How Do I Solve This Step By Step? I Dont Know How To Set Up This Equation

Answers

Answer 1

Answer:

23

Step-by-step explanation:

The markings show that the vertical line and the hypotenuse are bisected. That means that the common ratio is 1/2.

(x - 8) / 30 = 1/2                     Cross multiply

2(x - 8) = 30                           Divide both sides by 2

x - 8 = 30/2      

x - 8 = 15                                Add 8 to both sides

x-8+8 =15+8

x = 23

Lucy brought 4 of her scarves to a secondhand store to sell. She was paid the same amount
of cash for each scarf. Before she left, Lucy spent $10.50 of her earnings on a used sweater.
She had $7.50 remaining. What was the value of each scarf?

Answers

The value of each scarf from the sales will be $4.50.

Since Lucy spent $10.50 of her earnings on a used sweater and she had $7.50 remaining, the total amount that she made from the sales will be:

= $10.50 + $7.50

= $18.00

Since she sold 4 scarves, the cost of each scarf will be:

= $18.00 / 4

= $4.50

Therefore, the value of each scarf will be $4.50.

1: h= 28
2: h= -30
3: h= 15
4: h= -15

Answers

Step-by-step explanation:

→ 15 + 6h = 45 + 8h

→ -8h + 6h = 45 - 15

→ -2h = 30

→ h = 30/-2

→ h = -15

hope this answer helps you dear...take care and may u have a great day ahead!

Answer:

4

Step by step explanation:

15+6h=45+8h

15+6h-8h=45

6h-8h=45-15

-2h=45-15

-2h=30

h=-15

Does (5, 4) make the equation y = –7x true? Yes Or No

Answers

Answer:

No

Step-by-step explanation:

Given point ,

(5,4)

Substitute ,

y = -7x 4 = -7*5 4 = -35 ( Not true )

Answer:

No

Step-by-step explanation:

Substitute the x- coordinate into the equation and if the value equals the y- coordinate then it makes the equation true.

y = - 7(5) = - 35 ≠ 4

Thus (5, 4 ) does not make the equation true

What equation is graphed?

Answers

X^2/9-y^2/16=1 is what is graphed.

2w + y = 6
a. Find y if w = -4
b. Find y if w = 10

Answers

A. Y would be 14 since 2w would equal -8, and -8+14=6.
B. Y would be -14 because 2w would equal 20 and 20+(-14)=6

Answer:

a. Find y if w = -4 --- y = 14

b. Find y if w = 10 --- y = -14

Step-by-step explanation:

This is all about substitution!! For question a, we need to substitute "w" with "-4" ...

2 (-4) + y = 6

We know that a positive time a negative equals a negative...so 2 · -4 is -8.

-8 + y = 6

Now let's add 8 on both sides to isolate the variable...which equals to

y = 14

Onto question b...We substitute w with 10.

2 (10) + y = 6

 = 20 + y = 6

Subtract 20 from both sides to isolate "y"

y = -14

What is an equation of the line that passes through the point (-2,7)(−2,7) and is perpendicular to the line x-4y=24x−4y=24?

Answers

9514 1404 393

Answer:

  4x +y = -1

Step-by-step explanation:

The equation of the perpendicular line can be written by ...

swapping the x- and y-coefficients, negating one of themchoosing a new constant so the line goes through the given point.

The x- and y-coefficients in the given equation are 1 and -4, respectively. Since we want the leading coefficient positive, it is convenient to use 4 and 1 as the coefficients in the new equation. The constant can be found by substituting (x, y) = (-2, 7) to see what it is.

  4x +y = 4(-2) +7 = -1

The desired perpendicular line has an equation ...

  4x +y = -1
