The expression 3(x-9) is equivalent to
O 3(x)+9.
O 3(x)+3(9).
3(%) – 9.
O 3(x) - 3(9)

Hey there!

When we say (f + g)(2), we are adding both functions together and plugging in 2 for x.

Since f(x) is equal to 2x + 210 and g(x) is equal to 2x + 125, (f + g)(x) is equal to (2x + 210) + (2x + 125).

That can be simplified to 4x + 335.

So, (f + g)(x) = 4x + 335.

Let's plug 2 in for x and solve.

(f + g)(2) = 4(2) + 335

Multiply.

(f + g)(2) = 8 + 335

Add.

(f + g)(2) = 343

The x value is consistent for the values of both equations, in both x is defined as the number of hours spent exercising.

So, (f + g)(2), which is 343, is the amount of calories burned and the calorie deficit on a diet when 2 hours are spent exercising.

Hope this helps!

Answer:

Its D

Step-by-step explanation:

To solve this ratio problem, we need to determine the relationship between the given numbers and apply it to find the answer.

The given expression is:

9:3 :: 49 :

To solve this, we need to determine the relationship between 9 and 3, and then apply the same relationship to 49.

The symbol '::' represents the ratio or proportion between the numbers before and after it.

9 divided by 3 is equal to 3, so the relationship here is that the first number is three times the second number.

Now, let's apply the same relationship to 49:

49 divided by 3 is equal to 16.33, so we can say that the answer is 16.33.

The answer to the question is therefore 49 : 16.33.

Answer:

150

Step-by-step explanation:

We know that Scott's ratio of making the basket is 9/12. All we need to do is find out how many baskets he'll make if he attempts 200 shots.

So, 9/12 needs to become x/200. We don't know what x is yet, but there's a shortcut.

9/12 can be simplified by dividing 3 on the top and bottom.

9/12 ÷ 3/3 = 3/4

We can then see how many times 4 can go into 200.

200/4 = 50

So, we multiply 3/4 by 50 on both the top and bottom.

3/4 × 50/50 = 150/200.

So, if he attempts 200 shots then he'll make 150 of them.

Scott can expect to make approximately 150 baskets if he attempts 200 shots with his success rate being 9 out of 12, which equates to a 75% success rate.

The question asks how many baskets Scott can expect to make if he tries 200 shots given that his average success rate is 9 out of 12. To find the answer, we can set up a proportion because Scott's shooting is a matter of probability and ratios. First, we determine Scott's success rate as a fraction: 9/12 which simplifies to 3/4 or a success rate of 75%.

Then, we apply this success rate to the new number of attempts (200) to find the expected number of successful baskets:

Therefore, if Scott attempts 200 shots, he can expect to make approximately 150 baskets.

angle list: k,l,j:

sides are:  LJ, KJ, KL

To find the sides of triangle JLK in order from smallest to largest, we need to compare the measures of the angles. The side opposite the largest angle is the longest side, so we can determine the order of the sides based on the angle measures.

The triangle JLK has angles J, L, and K with measures 82, 57, and 41 degrees, respectively. To determine the sides of JLK in order from smallest to largest, we can use the fact that the side opposite the largest angle is the longest side. So, we need to identify the largest angle and its corresponding side.

Comparing the measures of the angles, we can see that M∠J is the largest angle. Therefore, the side opposite angle J, which is side JL, is the longest side. Next, we compare the measures of the remaining angles. M∠L is the next largest angle, so the side opposite angle L, which is side LK, is the second longest side. Finally, M∠K is the smallest angle, so the side opposite angle K, which is side JK, is the shortest side.

Therefore, the sides of triangle JLK in order from smallest to largest are JK, LK, JL.

Domain: [tex][-2,6][/tex]

Range: [tex][0,5][/tex]

Explanation:

Domain:

The domain of a function is the set of all possible values of the independent variable x. From the graph, we can see that the function has the set of all possible values from -2 to 6. Hence, the domain is from -2 to 6.

Thus, writing the domain in interval notation, we have,

[tex]-2\leq x\leq 6[/tex]

This also can be written as [tex][-2,6][/tex]

Hence, the domain is [tex][-2,6][/tex]

Range:

The Range of a function is set of all possible values of y obtained by substituting the values for x in the function. From the graph, we can see that the function has the set of all possible values from 0 to 5. Hence, the range is from 0 to 5.

Thus, writing the range in interval notation, we have,

[tex]0\leq y\leq 5[/tex]

This also can be written as [tex][0,5][/tex]

Hence, the range is [tex][0,5][/tex]

The domain and range in interval notation represent sets of possible values a function can take. For instance, for the function f(x) = 2x + 3 where x can be any real number, both the domain and range would be (-∞, ∞). Square brackets denote inclusive endpoints, while parentheses denote exclusive endpoints in interval notation.

In mathematics, particularly in functions, the domain and range represent sets of possible input and output values respectively. When expressed in interval notation, domain and range convey a concise representation of these sets.

Let's illustrate with an example. If we have the function f(x) = 2x + 3, and x can be any real number, the domain in interval notation would be (-∞, ∞). As for the range, since the function can also output any real number, the range would also be (-∞, ∞).

To write the domain and range in interval notation, remember that square brackets [ ] represent inclusive endpoints, while parentheses ( ) represent exclusive endpoints. The symbol '∞' is always cloaked by parentheses.

Question:

Crispy clover, a popular vegetarian restaurant, introduced a new menu that had 20% more dishes than the previous menu. The previous menu had D dishes. Which of the following expressions could represent how many dishes crispy clovers new menu has?

Answer:

The expression could represent how many dishes crispy clovers new menu has is:

[tex]D + \frac{1}{5}D \text{ or } 1.2D[/tex]

Solution:

Given that,

The new menu had 20% more dishes than the previous menu

The previous menu had D dishes

Therefore,

Previous menu = D dishes

New menu = 20 % more dishes than previous menu

Which means,

New menu = 20 % of previous menu + previous menu

Therefore,

New menu = 20 % of D + D

Solve the above equation

[tex]New\ menu = 20 \% \times D + D\\\\New\ menu = \frac{20}{100} \times D + D\\\\New\ menu = 0.2 \times D + D\\\\New\ menu = 0.2D + D = \frac{D}{5} + D = 1.2D[/tex]

Answer:

Cost of each cherry pie = $6

Cost of each blackberry pie = $16

Step-by-step explanation:

Let x be the cherry pies and y be the blackberry pie.

Solution:

From the above statement Jasmine sold 12 cherry pies and 4 blackberry pies for a total of $136.

So, we write the first equation as.

[tex]12x+4y = 136 ------(1)[/tex]

And Stephanie sold 8 cherry pies and 1 blackberry pie for a total of $64.

So, we write the second equation as.

[tex]8x+y = 64 --------(2)[/tex]

First we solve equation 2 for y.

[tex]y = 64-8x[/tex] ------------------------(3)

Substitute [tex]y = 64-8x[/tex]  in equation 1.

[tex]12x+4(64-8x) = 136[/tex]

[tex]12x+256-32x=136[/tex]

[tex]12x-32x=136-256[/tex]

[tex]-20x=-120[/tex]

[tex]x=\frac{120}{20}[/tex]

x = 6

Substitute x = 6  in equation 3.

[tex]y = 64-8(6)[/tex]

[tex]y=64-48[/tex]

y = 16

Therefore, cost of each cherry pie = $6 and cost of each blackberry pie = $16

By solving the system of equations, it is determined that the cost of one cherry pie is $6 and the cost of one blackberry pie is $16. These findings are crucial for pricing strategies in the school fundraiser.

To solve the system of equations for the cost of cherry and blackberry pies sold by Jasmine and Stephanie for a school fundraiser, we can set up two equations based on the given information:

Let's denote the cost of one cherry pie as c and the cost of one blackberry pie as b. Therefore, we can form the following equations based on the problem statement:  

Using the method of substitution or elimination, we solve for c and b.

For simplicity, let's use elimination. To eliminate b, we can multiply the second equation by -4 and add to the first:

-32c - 4b = -256
12c + 4b = 136

Combining these, we get -20c = -120, thus c = $6. Substituting c = 6 into the second equation, 8*6 + b = 64, gives us b = $16.

In real-life terms, this means one cherry pie costs $6, and one blackberry pie costs $16, which would be important for pricing and accounting in the fundraiser.

The equation have infinite solutions.

Final answer:

The total surface area of a square prism with a base edge of 6 km and height of 5 km is 192 km².

Explanation:

The question is about finding the surface area of a square prism (also known as a rectangular prism where the base is a square). A square prism has six faces: two square bases and four rectangular sides. To find the total surface area, we calculate the area of each face and sum them up.

The formula for the area of a square is side × side. Since the base of the prism is a square with each side measuring 6 km, the area of one square base is:

Since there are two square bases:

The formula for the area of a rectangle is length × width. The four rectangular sides each have one dimension that is the height of the prism (5 km), and the other dimension is the length of a side of the base (6 km), so:

There are four such sides:

Adding the areas of the bases and the sides:
