Hello!
695 - 7x = 140
-7x = 140 - 695
-7x = -555
-x = -79.29
x = 79.29
I hope this helps you! Have a lovely day!

Answer:
b) - 10
Step-by-step explanation:
<h3>Average rate of change:</h3>
To find the average rate of change, we have divide the change in y of f(x) , by the change in x(input).
a = 4 ; f(a) = -17
b = 6 ; f(b) = -37
Answer:
f(x)= -(x^3+10x^2-275x-1500) Standard
f(x)= -(x+20)(x+5)(x-15)
Step-by-step explanation:
The factored form of the equation is:
(x+20)(x+5)(x-15)=f(x) Each of the zeroes are where the graph crosses the x-axis.
The expanded form of the equation is found by using FOIL on the equations above:
-x^3+10x^2-275X-1500
The leading coefficient is negative because the graph rises to the left and falls to the right.
