B because when you combine all of those terms, x^4 + 7x^4, and 3x^3 - 2x^3, and x^2 - 5x^2, and x - x, and 1 you get 8x^4 + x^3 - 4x^2 + 1.

A company finds that there is a linear relationship between the amount of money that it spends on advertising and the number of

Kay [80]

The formula for the equation of y, the number of units sold as a function of x is y = 0.00625x + 250

<h3>How to illustrate the equation?</h3>

From the information given, when the company spends no money on advertising, it sells 250 units and for each additional $4000 spent, an additional 25 units are sold.

The formula for y will be:

y = (25/4000)x + 250

y = 0.00625x + 250

Answer:

-20

Step-by-step explanation:

First, you divide both sides by -2/5, which would get you c = 8 * -5/2 (Because when you divide, you multiply by the reciprocal). 8 * -5/2 is equal to -20. The answer is -20.

How do you find the area of this composite figure?

Yanka [14]

Split the shape into smaller shapes, (see attachment)
find the area of the split shapes. So first find the area of the triangles
A = 1/2bh
A = 1/2*2*3
A = 1/2*6
A = 3
so that is the area of one triangle. the area of the other is
A = 1/2*4*3
A = 1/2 * 12
A = 6
now find the area of the rectangle
A = l*w
A = 9*3
A = 27
add them all together
27 + 6+ 3 = 36
the area of the total figure is 36
