Answer:
B. 20 years
Step-by-step explanation:
By using the process of trial and error, if Gina is 20 years old, that would mean her sister is 29 years old. This is because 20+9 is equal to 29. 29+20 sums up to 49.
Hey there!
First, we'll solve for x = 0.
The first step is to replace x with 0 anytime it appears in the equation.
f(0) = 7(0) + 2
Multiply 7 by 0 next because multiplication comes before addition in PEMDAS.
f(0) = 0 + 2
Then, add 2 to 0 since it is the last step.
f(0) = 2 The value of f(x) when x = 0 is 2.
Now we can solve for x = 1.
The first step is to replace x with 1 anytime it appears in the equation.
f(1) = 7(1) + 2
Multiply 7 by 1 next because multiplication comes before addition in PEMDAS.
f(1) = 7 + 2
Then, add 2 to 7 because it is the last step.
f(1) = 9 The value of f(x) when x = 1 is 9.
Hope this helps!
I’m not sure if this is right. but wouldn’t it be 0 if he spent the remaining amount of money on supplies for an art project?
