Jerry bought a bottle of perfume for a gift for his wife.The perfume cost $92 before tax.

If the total price including tax was $98.90, find the tax rate.

Answers

First, you need to find how much money the tax was (98.90-92=6.9) Then, divide the tax by the price without the tax to find the tax rate (6.9/92=.075) then multiply the answer by 100 (.075*100=7.5)The tax rate is 7.5%

Alan has scored 99, 85, and 74 on his previous three tests. What score does he need on his next test so that his average (mean) is 83?

Answers

(99+85+74+x)/4=83
multiply both by 4
99+85+74+x= 332
258+x=332
subtract 258 both sides
x= 74

He must get a 74.

To check answer:
99+85+74+74= 332
332/4 = 83

It’s right!

Hope it helps

Mrs. Colen took a trip. She drove 350 miles in 7 hours and 30 minuets. what is her average speed to the nearest tenth of a mile per hour

Answers

diatance travelled by her= 350 miles
amount of time taken by her to travel 350 miles= 7 hrs 30 mins
                                                                      =450 mins
 average speed travelled by her to the nearest tenth of a mile per hour= 450*60/100
                                                                                                      =270/10
                                                                                                      =27
 therefore he travelled 27 miles to the nearest tenth of a mile per hour.   
7 hours and 30 minutes is 7.5 hours. Average speed can be found by taking distance and dividing it by time. 350 miles/7.5 hours=46.6666 miles per hour. Rounded to the nearest 10th that is 46.7 mi/hr

Choose the correct graph of the given system of equations.y + 2x = −1

graph of two lines that intersect at the point (negative 1, 1)
graph of two lines that intersect at the point (1, 1) < Not
graph of two parallel lines with positive slopes
None of the above

Answers

Answer: Graph of two lines that intersect at the point (negative 1, 1).

Step-by-step explanation:

The given system of linear equations :

y+2x=-1---------(1)\n\n3y-x=4-------------(2)

Multiply equation (1) by 3 , we get

3y+6x=-3-------------(3)

Subtract equation (2) from (3), we get

6x+x=-3-4\n\n 7x=-7

Divide both sides by 7 , we get

x=-1

Put value of x in (1), we get

y+2(-1)=-1\n\n y-2=-1\n\n y=-1+2=1

⇒ both lines are intersecting at (x,y)=(-1,1)

∴  The correct graph of the given system of equations : graph of two lines that intersect at the point (negative 1, 1)

Answer:

(-1,1) One solution

Step-by-step explanation:

Use these steps for the equations:

1)  Rewrite the equation in slope intercept form.

2) Graph the first equation.

3) Graph the second equation.

4) Identify the point of intersection.

What’s the answer to this

Answers

Answer:

A

Step-by-step explanation:

Given f(x) the f(x) + c represents a vertical translation of f(x)

• If c > 0 then a shift up of c units

• If c < 0 then a shift down of c units

Here c = - 6, thus a shift down, thus

g(x) = x² - 6  → A
