Create a function table for inputs -2, 0, 2 and 4
When x = -2
When x = 0
When x = 2
When x = 4
So, the table is:
Answer:
B
Step-by-step explanation:
use the slope formula to find the slope. y2-y1/x2-x1. 3-(-6)/-4-2 which is 9/-6 (subtracting a negative number is the same as adding a positive) which can be simplified to -3/2 which is the slope. the intercept is the point where y is at x=0, we already know at y=3 x is -4 from the second point, so the y intercept has to be -3. which can be proven by replacing the x and y with a point 3 = -3/2(-4) - 3. put -3/2 times 4 into a calculator and you get 6, 6-3 is 3 which makes the statement true.
You multiply the number outside the parenthesis with both of the numbers in the parenthesis separately.
OK so if 70% of students in 8th grade have siblings and 112 8th graders have siblings, then:
0.7(total 8th graders) = 112
total 8th graders = 112/0.7
total 8th graders = 160
And since the number of 8th graders is 5/6 the size of the 7th grade class:
5/6(7th grade class) = 160
5(7th grade class) = 960
7th grade class = 192.
The correct answer is D) 192.
