Answer:

Step-by-step explanation:

Let the number be x

5 is subtracted from a certain number means it will be x - 5

The result is multiplied by 7, the final result is 63,

7 (x - 5) = 63

7x - 35 = 63

7x = 63 + 35

7x = 98

x = 98/7

x = 14

The number is 14

Answer the number is 14 and the equation is 7 (x - 5) = 63

Answer:

The original number is 4

Step-by-step explanation:

Let x be the number.

5 is added to x => 5+x

When it is multiplied by 3,

3*(5+x) = 27

=> 15 + 3x = 27

Subtract 15,

3x = 27 - 15 = 12

Divide by 3,

x = 4

Graph each line. Give the slope-intercept form for all standard form equations.
8090 [49]

Answer:

Slope Intercept Form is y=2x.

Step-by-step explanation:

Since slope-intercept form is y=mx+b, you need to rewrite 2x-y=0 in Slope-Intercept Form.

First, you want to subtract 2x from both sides. That comes out to -y = (-2x.)

Then, multiply each term by -1. A negative times another negative is a possitive, so -y would become y, and -2x would become 2x, giving you the answer of y=2x.

What is the value of x?<br> 85°<br> 92°<br> 53°
MAXImum [283]

Answer:

x = 46

Step-by-step explanation:

Vertical angles are equal so call the angle y

85+53 +y =y+ 92+x

Subtract y from each side

85+53  = 92+x

Combine like terms

138 = 92+x

Subtract 92 from each side

138 -92 = 92+x-92

46 =x

If K(4,-5) is rotated counter clockwise 270°, what will be the coordinates of its image?
UkoKoshka [18]

Answer:

(-5, -4)

Step-by-step explanation:

The formula for a point (x, y) rotating 270 degrees counterclockwise is that it turns into (y, -x). Thus, for (4, -5), its image would be (-5, -4)
