Answer:
12a + 24 = 6(2a + 4) is the equivalent expressions
Step-by-step explanation:
Given the terms ; 4, 12a, 6, 2a, and 24
There are two terms with unknown = 12a and 2a
but 12a = 2a x 6 .........(1)
from the last term = 24 = 6 x 4 ...........(2)
add both equation 1 and 2 = 12a + 24
12a + 24 = 6(2a + 4) is the equivalent expressions .
to VERIFY; Use a = 2
substitute into the expression ; LHS = RHS
= 12(2) + 24 = 24 + 24 = 48 (LHS)
FOR RHS = 6(2a+4) = 6(2x2 + 4)
= 6(4+4) = 48
Hence LHS = RHS
Which graph is the result of reflecting f(x) = One-fourth(8)x across the y-axis and then across the x-axis? On a coordinate plane, an exponential function approaches y = 0 in quadrant 2 and incresaes into quadrant 1. It goes through the y-axis at (0, 0.25) and goes through (1, 2). On a coordinate plane, an exponential function approaches y = 0 in quadrant 1 and increases in quadrant 2. It crosses the y-axis at (0, 0.25) and goes through (negative 1, 2). On a coordinate plane, an exponential function approaches y = 0 in quadrant 3 and decreases into quadrant 4. It crosses the y-axis at (0, negative 0.25) and goes through (1, negative 2). On a coordinate plane, an exponential funtion increases in quadrant 3 into quadrant 4 and approaches y = 0. It goes through (negative 1, negative 2) and crosses the y-axis at (0, negative 0.25).
On a coordinate plane, an exponential function increases in quadrant 3 into quadrant 4 and approaches y tends to zero, which goes through (-1,-2) and crosses the y-axis at (0,-0.25).
What is a function?Function is a type of relation, or rule, that maps one input to specific single output.

find the volume of a pyramid 8 base length 5 base width 12 height
Answer:
The volume is 160 cubic units
Step-by-step explanation:
1. Information given to us to answer the question correctly:
8 = base length
5 = base width
12 = height
2. Let's recall the formula of the volume of a pyramid with rectangular base:
Volume = (Length * Width * Height)/3
Volume = (8 * 5 * 12)/3
Volume = 480/3 ?
Volume = 160 cubic units
3x + 2y = 6 is an equation in standard form
Answer:
The value of y when x is 0 is 3
The value of x when y is 0 is 2
Step-by-step explanation:
3x + 2y = 6
3(0) +2y=6—> replace x with 0
2y=6—> divide both sides by 2
y=6
And do the same for y!
The equation 3x + 2y = 6 is a linear equation in standard form. Also, the equation y = 9 + 3x is an equivalent linear equation in slope-intercept form where b is 9 (y-intercept) and m is 3 (slope). A table of (x, y) values derived from this equation would plot as a straight line on a graph.
Explanation:The equation you're looking at, 3x + 2y = 6, is indeed a linear equation in standard form. As a refresher, a standard form equation is written as Ax + By = C, where A, B, and C are constants, and x and y represent variables.
Let's consider another similar example, y = 9 + 3x. In this equation, which is in slope-intercept form, the b term has been set equal to 9 and the m term has been set equal to 3. We can fill out table A1 with different values for x and calculate the corresponding values of y. When plotted on a graph, these points will form a straight line, as dictated by the nature of linear equations.

HELP QUICK I NEED TO KNOW THIS Three pirates named Ahab, Sparrow, and Davy play a game. The pirates have a total of 210 coins, and each pirate has a different number of coins. At the end of the game, Ahab has won 5 coins and Davy has won 7 coins. Now, the ratio of coins belonging to Ahab, Sparrow, and Davy is 4:5:6, respectively. How many coins did Sparrow have at the beginning of the game?
The number of coins Sparrow has at the beginning of the game is 92 coins.
How many coins did Sparrow have at the beginning of the game?
Total number of coins = 210.
Ratio of coins belonging to Ahab, Sparrow and Davy = 4 : 5 : 6
Let
x = multiplying factor
The number of coins to Ahab = 4x
The number of coins to Sparrow = 5x
The number of coins to Davy = 6x
Since, total number of coins = 210
So
4x + 5x + 6x = 210
15x = 210
Divide both sides by 15
x = 16
Therefore,
The number of coins to Sparrow = 5x
= 5 × 16
= 80 coins
At the end Ahab and Davy wins 5 and 7 coins respectively
So at the beginning of the game, the number of coins Sparrow has = 80 + 7 + 5
= 92

Martina runs 7 miles in 50 mins at the same rate how many miles will she run in 75 mins
Martina runs 10.5 miles in 75 minutes
Solution:
Given that,
Martina runs 7 miles in 50 minutes
Therefore, miles ran in 1 minute is:
[tex]Miles\ ran\ in\ 1\ minute = \frac{7}{50}\ miles[/tex]
At the same rate how many miles will she run in 75 mins
Thus, to find the miles ran in 75 minutes:
[tex]Miles\ ran\ in\ 75\ minute = \frac{7}{50}\ \times 75\\\\Miles\ ran\ in\ 75\ minute = 0.14 \times 75\\\\Miles\ ran\ in\ 75\ minute = 10.5[/tex]

Option D: [tex]\frac{2}{5}[/tex] is the x-coordinate
Explanation:
It is given that the coordinates of the line segment are A(3,2) and B(6,11).
Since, the line is partitioned by the point C by the ratio AC : BC = 2 : 3
The distance between the x-coordinates is 3 units.
To determine the value of the x-coordinate for point C, let us divide the value of x-coordinate from the ratio divided by the sum of ratio.
The value of x-coordinate from the ratio is 2.
Sum of the ratio is 2 +3 = 5
Thus,
The x - coordinate = value of x-coordinate from the ratio / Sum of ratio = 2/5
Substituting the values, we have,
The x - coordinate of the Point C = [tex]\frac{2}{5}[/tex]
Thus, Option D is the correct answer.

The unknown resistance is approximately 0.44 Ω.
Solution:
Total (equivalent) resistance = 0.28 Ω
Resistance 1 = ?
Resistance 2 = 0.81 Ω
To find the unknown resistance.
Formula for determining equivalent resistance in a parallel circuit:
[tex]$\frac{1}{R_{e q}}=\frac{1}{R_{1}}+\frac{1}{R_{2}}[/tex]
Substitute the given values in the formula.
[tex]$\frac{1}{0.28}=\frac{1}{R_{1}}+\frac{1}{0.81}[/tex]
[tex]$3.571=\frac{1}{R_{1}}+1.235[/tex]
Subtract 1.235 on both sides of the equation, we get
[tex]$2.282=\frac{1}{R_{1}}[/tex]
Take reciprocal to find [tex]R_1[/tex].
[tex]$R_{1}=\frac{1}{2.282}[/tex]
[tex]$R_{1}=0.44[/tex]
[tex]R_1[/tex] = 0.44 Ω
The unknown resistance is approximately 0.44 Ω.

Consider the dilation of square KLMN by a scale factor of 1/4, with a center of dilation at the origin. Assume the units are centimeters.
1. What is the perimeter of the square after the dilation? Explain the change in the perimeter.
2. What is the area of the square after the dilation? Explain the change in the area.
1. The given squares perimeter after dilation is 16 cm. Perimeter is reduced by 48 cm due to dilation.
2. The squares area is 16 square centimeters after dilation. The area reduces by 240 square cm due to dilation
Step-by-step explanation:
Step 1; First, we determine the coordinates of the points given in the graph. By plotting we determine that the points are; K (-8, -8), L(8,-8), M(8, 8) and N(-8, 8).
Step 2; We calculate the new coordinates of the square KLMN by multiplying the scale factor with each of the coordinate's x and y values.
8 × [tex]\frac{1}{4}[/tex] = 2, -8 [tex]\frac{1}{4}[/tex] = -2 are the different values in the four coordinates.
So by multiplying the scale factor we get the dilated square's points as
K (-2, -2), L(2,-2), M(2, 2) and N(-2, 2).
Step 3; The perimeter of a square is given by 4 times its side length. As the units are in centimeters, we determine the side length is 4 cm whereas it is 16 cm for the undilated square.
Perimeter of original square = 4 × 16 cm = 64 cm
Perimeter of the dilated square = 4 × 4 cm = 16 cm.
Change in perimeter = Perimeter of original square - Perimeter of the dilated square = 64 cm - 16 cm = 48 cm.
Step 4; The area of any given square is the side length of the square squared. The side length of the original square is 16 cm whereas the side length of the dilated square is 4 cm.
Area of original square = 16 × 16 cm = 256 square cm
Area of the dilated square = 4 × 4 cm = 16 square cm.
Change in area = area of original square - area of the dilated square = 256 cm - 16 cm = 240 square cm.

There are 3 caterpillars on each plant, and there are 2 caterpillars on the ground. The table shows how the number of caterpillars, c, depends on the number of plants, p. Choose the equation which represents the rule.
A) c = 3p + 3
B) c = 2 − 3p
C) c = 3p − 2
D) c = 3p + 2
Answer:
c = 3p + 2 is the equation that shows relation between number of caterpillars and plants
Solution:
Given that,
There are 3 caterpillars on each plant
And there are 2 caterpillars on the ground
Let the number of plants be "p"
Let the number of caterpillars be "c"
The equation that shows relation between number of caterpillars and plants is:
If there are 3 caterpillars on each plant, then for "p" plants, there will be "3p" caterpillars
Number of caterpillars = 3p + 2 caterpillars on the ground
Therefore,
Number of caterpillars = 3p + 2
c = 3p + 2
Thus the equation is found
