Answer:
-7
Step-by-step explanation:
-7 is the number that is attached to the y. It is the coefficient. Another possible coefficient is 1, but you do not need to write it, as anything multiplied by 1 is equal to the original number.

Problem 1
Answer: Choice A
Vertically stretching it by a factor of 2 is the same as compressing it horizontally by a factor of 2
====================================================
Problem 2
Answer: choice B
Add up the functions to get
M(s) + L(s) = (225+0.65s) + (54 + 1.15s)
M(s) + L(s) = (225+54) + (0.65s+1.15s)
M(s) + L(s) = 279 + 1.80s
If the mean is 67, the total of all the data values has to be 67*4, or 268. 268-56-63-70 = 79, which means the fourth data value has to be 79.
Answer:
6 * 42 = 6 * (20 + 22)
= (6 * 20) + (6 * 22) = 120 + 132 = 252
Step-by-step explanation:
Here, we want to multiply 6 by 42 using distributive property
In this case, we can have the distributive property as;
a * ( b + c) = ab + bc
Thus, we can represent 42 as (20 + 22)
so 6 * 42 becomes 6 * (20 + 22)
Using the distributive property, we have
(6 * 20) + (6 * 22)
= 120 + 132 = 252
