Answer:

x=1

Step-by-step explanation:

hello :

3x+3 =6

means : 3x+3-6 =6-6

           3x -3 =0

add 3 : 3x = 3 divid by 3 : x=3/3=1

The required simplified value of the x for which the function gives f(x) = 6 is given as x = 1.

The process in mathematics to operate and interpret the function to make the function or expression simple or more understandable is called simplifying and the process is called simplification.

Here,
Given function,
f(x)=3x+3,

Since we have given f(x) = 6, we have to determine the value of x for which the function gives 6,
Now,
f(x)=3x+3

Substitute f(x) = 6
6 =3x + 3
3x = 6 - 3
3x = 3
x = 1

Thus, the required simplified value of the x for which the function gives f(x) = 6 is given as x = 1.

Answer:  y intercept

Step-by-step explanation:

Answer:

1) one solution

2) Infinitely many solution

3) no solution

Step-by-step explanation:

The first equation is -14-8x=-2(-3x+7)

Let us expand the right hand side to get:

-14-8x=-2*-3x+-2*7

We multiply -14-8x=6x-14

We group similar terms to get:

-8x-6x=-14+14

Combine similar terms to get:

-14x=0

Divide through by -14 to get:

x=0

2) The second equation is 3+5x=5(x+2)-7

We expand to obtain:

3+5x=5x+5*2-7

Multiply to get:

3+5x=5x+10-7

This gives us

3+5x=5x+3

5x=5x

1=1

There is infinitely many solutions

3) The third equation is: 36-7x=-7(x-5)

We expand to get:

36-7x=-7x+35

Group similar terms;

-7x+7x=35-36

0=-1

This statement is not true so there is no solution.

Answer:

Step-by-step explanation:

To find the difference, first calculate how much 3 pounds of each meat costs.

$3.20 × 3 = $9.60 for 3 pounds of chicken

$4.59 × 3 = $13.77 for 3 pounds of beef

Now, take the difference.

$13.77 - $9.60 = $4.17

3 pounds of beef costs $4.17 more than 3 pounds of chicken.

Answer:

3 pounds of beef costs $4.17 more than 3 pounds of chicken

The factors common to 12x and 18xy are 1, 2, 3, 6, and x.

The factors common to 12x and 24y are 1, 2, 3, 4, 6, and 12.

The GCF of the expression is 6.

Answer: Options B, C and E.

Explanation:

Factors are numbers we can increase together to get another number. At the point when we discover the components of at least two numbers, and afterward discover a few variables are the equivalent ("normal"), at that point they are the "basic elements".

These are the factors which are common in the whole expression or are common in any two equations at the time of comparison. The common factor which is the biggest is known as the greatest common factor.

Answer:

B,C,E

Answer:i think it is 0

Step-by-step explanation:

You can use the fact that if (x-root) is a factor of a single variable polynomial function p(x) = 0

A binomial factor of p(x) is (x-2)

Let its root be x = k

Then we have one of the factor of polynomial as (x-k)

Root of a polynomial function p(x) is a value of x such that putting that value in place of x makes the output 0.

Thus, if x = k is a root of the polynomial p(x), then

p(k) = 0

Since it is given that

p(2) + 4=4

thus,

p(2) = 4-4 = 0

Thus, x = 2 is a root of the polynomial function, and thus, using the aforesaid conclusions, we have (x-2) as one of the factors of the considered polynomial function.

Thus,

A binomial factor of p(x) is (x-2)

The given figure is missing so I attached it below

m∠ A B C = 72°

m∠ F B C = 108°

m∠ A B D = 90°

m∠ D B E = 18°

Step-by-step explanation:

∵ Lines A F and C E are intersected at point B

∴ ∠ A B C and ∠ F B E are vertical opposite angles

- That mean they are equal in measures

∴ m∠ A B C = m∠ F B E

∵ m∠ F B E = 72°

∴ m∠ A B C = 72°

∵ Ray F B and line E C are intersected at B

∴ ∠ C B F and ∠ F B E formed a pair of linear angles

- Their measures is 180°

∴ m∠ C B F + m∠ F B E = 180°

∵ m∠ F B E = 72°

∴ m∠ C B F + 72 = 180

- Subtract 72 from both sides

∴ m∠ C B F = 108°

∵ Ray B D ⊥ to line A F

- That mean ∠ A B D and ∠ F B D are formed a pair of linear

  angles equal in measures, then their measures is 180 ÷ 2 = 90

∴ m∠ A B D = m∠ F B D = 90°

∴ m∠ A B D = 90°

∵ Ray B E divides ∠ D B F into two angles D B E and F B E

∵ m∠ F B D = 90°

∴ m∠ D B E + m∠ F B E = 90°

∵ m∠ F B E = 72°

∴ m∠ D B E + 72 = 90°

- Subtract 72 from both sides

∴ m∠ D B E = 18°

Step-by-step explanation:

This is the graph:

-5x=14

Answer:

$13,952.30

Step-by-step explanation:

refer to attached graphic

the formula for compound interest is given as

A = P [ 1 + (r/n) ] ^ (nt)

where

A = final amount (we are asked to find)

P = principal amount = $13,500

r = rate = 3.3% = 0.033

n = 12 (compounded monthly)

t = 1 year

substituting these values into the equation

A = 13500 [ 1 + (0.033/12) ] ^ [(12)(1)]

A = 13500 [ 1 + 0.00275 ] ^ 12

A = 13500 [1.00275 ] ^ 12

A = 13500 (1.0335)

A = $13,952.30

The balance on a $13,500 deposit earning 3.3% and compound monthly after 1 year is equal to $13,952.30.

In Mathematics and Financial accounting, compound interest can be calculated by using the following mathematical equation (formula):

[tex]A(t) = P(1 + \frac{r}{n})^{nt}[/tex]

Where:

By substituting the given parameters into the formula for compound interest, we have the following;

[tex]A(1) = 13500(1 + \frac{0.033}{12})^{12 \times 1}\\\\A(1) = 13500(1.00275)^{12}[/tex]

Future value, A(1) = $13,952.30.

Answer:

3

Step-by-step explanation:

Option A:

Lateral surface area = 1319 cm²

Solution:

Given image is the cone.

Radius of the cone = 15 cm

Slant height = 28 cm

Value of π = 3.14

To find the lateral surface area of the cone:

Lateral surface area = [tex]\pi r l[/tex]

                                 [tex]=3.14\times 15\times28[/tex]

                                 =  1318.8 cm²

Change this to nearest whole unit.

Lateral surface area = 1319 cm²

Hence the lateral surface area of the cone is 1319 cm².

Final answer:

The center of the circle is (3, -4) and the radius is approximately 5.66 units.

Explanation:

To find the center and radius of the given circle, we need to rewrite the equation in the standard form of the equation of a circle. The standard form is: (x - h)^2 + (y - k)^2 = r^2, where (h, k) is the center of the circle and r is the radius.

So, let's complete the square for both x and y terms in the given equation:

(x^2 - 6x) + (y^2 + 8y) = 7

(x^2 - 6x + 9) + (y^2 + 8y + 16) = 7 + 9 + 16

(x - 3)^2 + (y + 4)^2 = 32

Now we can see that the center of the circle is (3, -4) and the radius is √32 or approximately 5.66 units.
