A local pizzeria sold 65 pizzas yesterday. Suppose the number of pizzas sold today was 60. Describe the number of pizzas sold as a percent increase or decrease, rounded to the nearest hundredth. Show your work.

% change formula=

(Old # - New #)/Old # x 100

65= old number

60= new number

% change= (65-60)/65 x 100

= 5/65 x 100

= 0.0769 x 100

= 7.69% change

ANSWER: There was a 7.69% decrease since the number of pizzas dropped from yesterday to today.

Hope this helped! :)

(Old # - New #)/Old # x 100

65= old number

60= new number

% change= (65-60)/65 x 100

= 5/65 x 100

= 0.0769 x 100

= 7.69% change

ANSWER: There was a 7.69% decrease since the number of pizzas dropped from yesterday to today.

Hope this helped! :)

How do the graphs of the functions f(x) = (3/2)x and g(x) = (2/3)x compare?

This is the graph. https://i.imgur.com/F9IBh3b.png

Red line is f(x) = (3/2)x

Blue line is g(x) = (2/3)x

Hope this somewhat helps.

Red line is f(x) = (3/2)x

Blue line is g(x) = (2/3)x

Hope this somewhat helps.

What is the rate of change of y=-3x - 2

Answer:

-3

Step-by-step explanation:

The rate of change is equal to the slope. In this slope intercept form (y=mx+b) m is the slope. Therefore m=-3 and that is the rate of change.

One number is 8 more than twice another. If their product is 640 , find the answers

Answer:

There are 2 answers

1. smaller number is -32, bigger number is -20

2. smaller number is 16, bigger number is 40

Step-by-step explanation:

Let x be the smaller number.

x(2x+8)= 640

expand

2x²+8x=640

move 640 to the other side and divide everything by 2

2x²+8x-640=0

x²+4x-320=0

use quadratic formulas to expand then group

x²+20x-16x-320=0

x(x+20)-16(x+20)

(x+20)(x-16)

x=-20

x=16

to find the bigger/smaller numbers, use 2x+8

2*-20+8= -32

2*16+8= 40

if you took 7 hours to mow 4 lawns, then at that rate, how many lawns could be lawns could be mowed in 35 hours? at what rate were lawns being mowed?

It takes 7 hours to mow 4 lawns

Therefore every hour, (4 ÷ 7) or 4/7 lawns are mowed. This gives the rate.

For 35 hours, 4/7 x 35 lawns are mowed.

=35 ÷ 7 = 5

= 4 × 5

= 20 lawns

Therefore every hour, (4 ÷ 7) or 4/7 lawns are mowed. This gives the rate.

For 35 hours, 4/7 x 35 lawns are mowed.

=35 ÷ 7 = 5

= 4 × 5

= 20 lawns
