Answer:
y =
Step-by-step explanation:
given that y and x are proportional then the equation relating them is
y = kx ← k is the constant of proportionality
to find k use the given condition y = 12 when x = 5
k = =
y = x ← equation of proportionality
when x = 8, then
y = × 8 =
Answer:
Equation 2 of system divided by 2 on both sides then we get second equation of system 2.
Step-by-step explanation:
We are given two equations
We are given a proof which shows an equivalent system of equations created from another system of equations
We have to fill the correct reason in the blank space
Statement:
Reason: Given
Statement :
Reason : equation 2 of system I divided by 2 on both sides then we get second equation of system 2.
When we divide by 2 then the solution does not change and x and y - intercepts are not change.So, the two systems are equivalent.
