Answers

Answer:

Slope 1: [tex]m=0[/tex]

Slope 2: [tex]m=5[/tex]

Slope 2 is bigger than slope 1.

General Formulas and Concepts:

Pre-Algebra

Order of Operations: BPEMDAS

Algebra I

Slope Formula: [tex]m=\frac{y_2-y_1}{x_2-x_1}[/tex]

Step-by-step explanation:

Step 1: Define

Slope 1

Point (-2, 3)

Point (1, 3)

Slope 2

Point (4, 21)

Point (9, 46)

Step 2: Find slope m

Slope 1

Substitute:                    [tex]m=\frac{3-3}{1+2}[/tex]Subtract/Add:               [tex]m=\frac{0}{3}[/tex]Divide:                          [tex]m=0[/tex]

Slope 2

Substitute:                   [tex]m=\frac{46-21}{9-4}[/tex]Subtract:                      [tex]m=\frac{25}{5}[/tex]Divide:                         [tex]m=5[/tex]

We know that 5 is greater than 0. ∴ Slope 2 is bigger than slope 1.

The first slope is: m = 0/3 OR m = 0
The second slope is: m = 5

4+(2x−7)3=−5 ?

Answers

Answer: x = 2.

Step-by-step explanation: Step 1: Simplify both sides of the equation.

4+(2x−7)(3)=−5

4+(2x)(3)+(−7)(3)=−5(Distribute)

4+6x+−21=−5

(6x)+(4+−21)=−5(Combine Like Terms)

6x+−17=−5

6x−17=−5

Step 2: Add 17 to both sides.

6x−17+17=−5+17

6x=12

Step 3: Divide both sides by 6.

6x /6  =  12 /6

x = 2.

it would be -3x+2x if you were talking about the whole question like 4+(2x-7)3=-5 it would be x=2

Three hundred vehicles are parked in a parking garage. Seventy percent of the vehicles are midsized cars. Which equation can be used to find the number of midsized cars in the parking garage?
StartFraction 300 divided by 3 Over 70 divided by 3 EndFraction = StartFraction 100 Over 23.3 EndFraction
StartFraction 100 divided by 3 Over 300 divided by 3 EndFraction = StartFraction 33 Over 100 EndFraction
StartFraction 70 times 3 Over 300 times 3 EndFraction = StartFraction 210 Over 900 EndFraction
StartFraction 70 times 3 Over 100 times 3 EndFraction = StartFraction 210 Over 300 EndFraction

Answers

Answer:

210 is the number of midsized cars

Step-by-step explanation:

Assume x is the number of midsized cars

So you can create the equation 70/100=x/300

(300*70)=100x

21000=100x

210=x

{Y'all... its 3/4 divided by 1/2}

Answers

Answer: 1 1/2
Explanation: the first number of the division problem stays the same but you flip the second fraction witch is 1/2 then that will be 2/1 then change the division symbol into a multiplication symbol and 3/4 times 2/1 and that equals6/4 and 6/4 is divisible by two so you divide 6/4 x 2. That equals 3/2 and you had to make that a mixed number so you divide two and 33 on the inside of the house and two on the outside. Two goes into threewants and when is your whole number and your remainder is one and one is your numerator and two is your denominator. You might understand it better if you see my work which a photo of it is down below.

A keyboard costs $400 is marked down 10% for a sale. What is the total savings?

Answers

Answer:

$40 in savings

Step-by-step explanation:

Turn the percentage into a decimal.

10% -> 0.1

Multiply.

400 * 0.1 = 40

Subtract.

400 - 40 = 360

Best of Luck!

You would save 40$, I know someone already answered it, but yeah.

I think that for me an easy way to figure it out is by dividing the % by the original price and you will find the amount you save. (Hope I help)
