A car company has found that there is a linear relationship between the money it spends on advertising and the number of cars it
Sveta_85 [38]

Answer:

The required formula for y, the number of cars sold is: y = 0.008x +200.

Step-by-step explanation:

Consider the provided information.

Let x represents the amount of money spend on advertising .

y is number of cars sold,

For each additional 5000 dollars spent, they sold 40 more cars.

Slope = m = \frac{Rise}{Run}=\frac{40}{5000}=0.008

The y-intercept form is: y = mx + b

Substitute x=60,000, y=680 and m=0.008 in the above equation.

680= 0.008(60,000)+b

b=680-480

b=200

Thus, the required formula for y, the number of cars sold is: y = 0.008x +200.

erica [24]

Answer:

x^18, or x¹⁸

Step-by-step explanation:

8¹⁵/8⁻³

8¹⁵ ₓ 8³

8¹⁸

When an exponent is negative, you have to flip what the exponent is attached to. If the negative exponent is the numerator(x⁻¹/1), it becomes a denominator(1/x¹). If the negative exponent is in the denominator (1/x⁻¹), it becomes a numerator(x¹/1).
