Answer:
<u>In 14 years Marc's grandmother will be 5 times as Marc will be then</u>
Step-by-step explanation:
1. Information given to us to solve the problem:
Marc's age today = 0
Marc's grandmother age today = 56
2. In how many years will Marc's grandmother be 5 times as Marc will be then?
x = Number of years when Marc's grandmother age will be 5 times as Marc will be then
Let's solve for x, this way:
5 times Marc age in x years = Marc's grandmother age in x years
5 (0 + x) = 56 + x
5x = 56 + x
5x - x = 56 (Subtracting x at both sides)
4x = 56
x = 56/4
<u>x = 14</u>
Let's prove that x = 14 is correct:
5 (0 + 14) = 56 + 14
70 = 70
We proved that x = 14 is correct
<u>In 14 years Marc's grandmother will be 5 times as Marc will be then</u>
Well evaluate means solve . so you just substitute the -18 in place of x you'll get -18-10/ 4
which is -28/4 = -7

Answer:
(g + f)(x)
Step-by-step explanation:
the outputs of f(x) and g(x) will always have a sum of -1, which is h(x).
Answer:
Option D
Step-by-step explanation:
' y = 4x − 1' would graph as a straight line. Therefore, it is a linear equation.
Liner equations are graphed as a straight line, while nonlinear equations are not.
