Step-by-step explanation:
8/1.4 = 0.175 which is how many each will have
Answer:
Slope is 1/2
Step-by-step explanation:
Using the slope formula y₂-y₁/x₂-x₁
(x₁,y₁) and (x₂,y₂) → (1,2) and (3,3)
So...
3-2=1
3-1=2
1/2
Answer:
The equation of the new function is 
Step-by-step explanation:
Suppose we have a function f(x).
a*f(x), a > 1, is vertically stretching f(x) a units. Otherwise, if a < 1, we are vertically compressing f(x) by a units.
f(x - a) is shifting f(x) a units to the right.
f(x + a) is shifting f(x) a units to the left
In this question:

Vertically compressing by 1/2:
This is the same as multiplying the function by 1/2. So

The equation of the new function is 
Instead of using PEMDAS or the Order of Operations, the student went ahead and solved the equation as though it were written 6 * 12 - 8.
The correct way to solve would be to first solve the parentheses. 12 - 8 is equal to 4. 4 times 6 is 24, giving us an answer of 24.
