Y = kx
80 = 16k
k = 80/16 = 5

The first 2 choices are corect
300miles÷15=20
Efficient:20miles/gallons of gas
7a+21=56
Begin by subtracting 21 on both sides:
21-21=0 so the 21 in the left cancels, then 56-21=35
Your new equation will be
7a=35
Finally, divide by 7 on both sides:
7/7=1 and 35/7=5
your answer will be
a=5
Answer:
x² is HCF (Height common factor)
Step-by-step explanation:
Given:
x² , x³
Find:
HCF (Height common factor)
Computation:
HCF (Height common factor) is uused to find Height common factor from the given numbers.
x² , x³
Takling x² as common
x² (1 , x)
So,
x² is HCF (Height common factor)
Answer:
If you need to know the intercepts, then standard form is easier because you can just plug in 0s. slope intercept is easier if you want to graph
