Correct answer is C.
Suppose the length of the edge of a cube is 1.
CQ = 1 and
the answer should be x=3/2
-15/-21 -14/x
-15x = -21 * -14
x = -19.6
answer -14c = -19.6 or about -20
answer 3c = .6 or about 1
formula would be
y= 1.2x -3
partial variation means the line doesn't go through (0,0)
D control, the researchers are creating a control group that experience all of the same conditions of the test group (receiving a pill) but receive no benefit of the vitamin. It helps to reduce variable in the study to determine validity
The first function is y = 4x + 5 so the slope is 4
To find the slope of the second function, do rise or run which is 6-10/1-3 = 2
since 4 is greater than 2, function 1 is greater so the answer is the second choice.
