<h3>Answer: Choice A.  3/4</h3>

Work Shown:

x = number of weeks

y = number of tests

slope = rise/run

slope = (change in y)/(change in x)

slope = 27/36

slope = (9*3)/(9*4)

slope = 3/4

A slope of 3/4 means that there are 3 tests for every 4 weeks.

Write the equation of the line parallel to y= -5 through (2,7) .
ololo11 [35]

Answer: y = 7

Step-by-step explanation: The equation of the original line in standard form is y = -5. Lines with a "y = b" equation are horizontal, so we know that the parallel line will also be horizontal and follow the y=b format. The original line passes through the point (2, 7) so the equation is y = 7.

Ahmed wrote an expression as 12x + 24, find all the equivalent expressions using the distributive property.
xeze [42]

Answer:

12x + 24 = 2(6x + 12)

12x + 24 = 3(4x +  8)

12x + 24 = 4(3x +  6)

12x + 24 = 6(2x +  4)

12x + 24 = 12(x +  2)

Step-by-step explanation:

Given

12x + 24

Required

Equivalent expressions

No option were given; So, I will list out some possible equivalent expressions.

Using distributive property:

AB + AC = A*(B + C)

So, we have:

12x + 24 = 2*6x + 2 * 12

12x + 24 = 2(6x + 12) ----- (1)

Another:

12x + 24 = 3*4x + 3 * 8

12x + 24 = 3(4x +  8)

Another:

12x + 24 = 4*3x +  4*6

12x + 24 = 4(3x +  6)

Another:

12x + 24 = 6*2x +  6*4

12x + 24 = 6(2x +  4)

Another:

12x + 24 = 12*x +  12*2

12x + 24 = 12(x +  2)
