Answer: f(x) - g(x) = -2x^2-3x+15

Step-by-step explanation:

To subtract functions, treat each function as a polynomial and subtract them as you would normally subtract polynomials.

f(x) = -3x + 7\\g(x) = 2x^2 + 8

f(x) - g(x) = (-3x+7)-(2x^2-8)\\\\f(x) - g(x) = -3x-2x^2+15

The correct answer is the fourth choice. It correctly subtracts the polynomials.

You want to buy a new car. You can afford payments of $300 per month and can borrow the money at an interest rate of 5.2% compou
Vikki [24]

Answer:

$367.17

Step-by-step explanation:

we are find the cost of the car after 5 years

Using the compound interest formula;

A = P(1+r/n)^nt

Given

Principal P = $300

rate r = 5.2% = 0.052

Time t = 5years

Time of compounding n = 1/12 (monthly)

Substitute into the formula

A = 300(1+0.052(12))^5(1/12)

A = 300(1+0.624)^0.4167

A = 300(1.624)^0.4167

A = 300(1.2239)

A = 367.17

hence the amount of the car after 5years is $367.17

On the dietitians beverage tray are 16 filled six ounce glasses. Four glasses contain prune juice and two glasses contain apple
zubka84 [21]

Answer:

\frac{5}{8}

Step-by-step explanation:

Given:

Total number of glasses = 16

Number of glasses containing prune juice = 4

Number of glasses containing apple juice = 2

To find:  fractional part of the glasses that contain beverages ( perhaps, H2O) other than prune juice and apple juice

Solution:

A fraction refers to the parts of a whole. In a fraction, a top number is the numerator, and a bottom number is the denominator.

Number of glasses that contain beverages ( perhaps, H2O) other than prune juice and apple juice = 16 - 4 - 2 = 10

Total number of glasses = 16

So,

Fractional part of the glasses that contain beverages ( perhaps, H2O) other than prune juice and apple juice = \frac{10}{16}=\frac{5}{8}

Monica paid sales tax of $3.20 when she bought a new bike helmet. If the sales tax rate was 8%, how much did the store charge fo
ICE Princess25 [194]

Answer: the store charged $40 for the bike helmet before tax.

Step-by-step explanation:

Let x represent the amount that the store charge for the bike helmet before tax.

If the sales tax rate was 8%, it means that the amount of tax that was charge is

8/100 × x = 0.08 × x = 0.08x

Monica paid sales tax of $3.20 when she bought a new bike helmet. This means that

0.08x = 3.2

Dividing the left hand side and the right hand side of the equation by 0.08, it becomes

0.08x/0.08 = 3.2/0.08

x = 40

If g(x) = -2x+7, what is the new function defined by h(x) = g(2x^2 +1)
hammer [34]

Answer:

h(x) = - 4x² + 5

Step-by-step explanation:

To find h(x) = g(2x² + 1), substitute x = 2x² + 1 into g(x)

h(x) = - 2(2x² + 1) + 7

      = - 4x² - 2 + 7

      = - 4x² + 5
