The sum of 5 times a number and -8:
5x - 8 = y
Step-by-step explanation:
RS = RT-ST
................
7 divided by 2 is 3.5 therefore the answer is:3.5
If y varies directly with x, that means they change at proportion rates. We can define their relationship using a constant k.
y = kx
Plug in what we know to find k.
-3 = 5k
k = -3/5
So:
y = -1 * (-3/5)
y = 3/5
