Answer: -1
Step-by-step explanation:
− 0.25(−8+12) = -0.25 x 4 =-1
A direct variation has a constant slope, i.e. (y/x)= constant.
Both of the given two points give a slope of (y/x)=14/2=28/4=7, so the equation of the function is
y/x=7, or simply
y=7x
Answer:
D
Step-by-step explanation:
X is increased by a factor of 5, so y should be multiplied by 5 as well. So y = 20*5=100
Number 1 is false and number 2 and 3 is true.
Sorry if it’s wrong I’m kinda of learning this too.
