Answer:
60
Step-by-step explanation:
había multiplicado 4 y 15 espero que esto ayude
Answer: B
Work:
-5x+10>-15 = x<3/10
A direct variation suggest that the value of x in the equation would greatly affect the value of y such that when x is increasing, y also increases and the other way around. The equation for a direct variation is that,
y = kx
Substituting the given values in the ordered pair,
5 = k(4) ; k = 5/4
