Answer:
$15.40
Step-by-step explanation:
At a given hourly rate, the pay is proportional to the hours spent earning it. So, we have ...
pay/hours = $17.92/3.2 = (mowing pay) / 2.75
Multiply by 2.75 to get ...
(mowing pay) = $17.92·(2.75/3.2) = $15.40
Hilary earned $15.40 mowing lawns.

Answer:
No, he is not correct. The initial value is 3, and the rate of change, or in graphing, the slope, is -5.
Step-by-step explanation:
Answer : the leading coefficients of f(x) and g(x) are opposites
if f(x) and g(x) are quadratic functions but (f+g)(x) produces the graph below
Let f(x) = ax^2 + bx +c
g(x) = dx^2 + ex + f
The graph attached is a linear graph
we need to produce linear graph by adding two functions ,
In linear graph, there is no x^2 term
To remove x^2 term, the coefficient of x^2 term should be same and of opposite sign
if d= -a , then g(x) = -ax^2 + 2x + f
f(x) + g(x) = (a-a)x^2 + (b+e)x + c+f= (b+e)x + c+f
f(x) + g(x) becomes linear
the leading coefficients of f(x) and g(x) are opposites
I think the answer is A. Cause your supposed to subtract so 7n-4n=3n, and 3-2=1 :) I hope this helps
