Yes that is right so you just plug in the days as x then multiply the new x with the number to the left of it then add the number on the right and finally that is your y
3x-52=2x+2 (v.o.a)
3x-2x=2+52
x=54
Answer:
try B if not maybe C
Step-by-step explanation:
"y varies directly with square of x"
y = kx²
where "k" is the constant of variation you need to solve for first.
when y = 100 ; x = 5
100 = k(5)²
100 = 25k
100/25 = k
4 = k
Now you can solve for y when x = 9
y = 4(9)²
y = 4(81)
y = 324
Step-by-step explanation:
OPTION A
(-40) + (-30) + 28
