Eight more than four times a number is 28.

Write the slope-intercept form of the equation of each line.

shtirl [24]

Answer:

12) $y = -x + 8$

11) $y = 12x + 22$

10) $y = 5x - 4$

9) $y = -2x + 1$

8) $y = 2x + 9$

7) $y = 12x - 28$

6) $y = 1\frac{1}{3}x + 2$

5) $y = 4x - 2$

4) $y = x$

3) $y = 1\frac{2}{5}x - 7$

2) $y = 2x - 4$

1) $y = \frac{2}{3}x - 8$

Step-by-step explanation:

12)

y - 4 = −(x - 4)

y - 4 = −x + 4

+ 4 + 4

__________

$y = -x + 8$

_______________________________________________

11)

y + 2 = 12(x + 2)

y + 2 = 12x + 24

- 2 - 2

____________

$y = 12x + 22$

_______________________________________________

10)

y - 1 = 5(x - 1)

y - 1 = 5x - 5

+ 1 + 1

_________

$y = 5x - 4$

_______________________________________________

9)

y - 5 = −2(x + 2)

y - 5 = −2x - 4

+ 5 + 5

___________

$y = -2x + 1$

_______________________________________________

8)

y - 5 = 2(x + 2)

y - 5 = 2x + 4

+ 5 + 5

__________

$y = 2x + 9$

_______________________________________________

7)

y + 4 = 12(x - 2)

y + 4 = 12x - 24

- 4 - 4

____________

$y = 12x - 28$

_______________________________________________

6)

4x - 3y = −6

-4x - 4x

__________

−3y = −4x - 6

___ _____

−3 −3

$y = 1\frac{1}{3} + 2$

_______________________________________________

5)

4x - y = 2

-4x - 4x

_______

−y = −4x + 2

$y = 4x - 2$

_______________________________________________

4)

x - y = 0

______

−y = −x

$y = x$

_______________________________________________

3)

7x - 5y = 35

-7x - 7x

_________

−5y = −7x + 35

___ ______

−5 −5

$y = 1\frac{2}{5}x - 7$

_______________________________________________

2)

2x - y = 4

-2x - 2x

_______

−y = −2x + 4

$y = 2x - 4$

_______________________________________________

1)

2x - 3y = 24

-2x - 2x

_________

−3y = −2x + 24

___ _______

−3 −3

$y = \frac{2}{3}x - 8$

Which ordered pair is a solution of the inequality y > 13x + 3

solong [7]

Answer:

x<y-3/13

Step-by-step explanation:

Switch sides'

13x+3<y

Subtract 3 from both sides

13x+3-3<y-3

Simplify

13x<y-3

Divide both sides by 13

13x/13<y/13-3/13

Simplify

x<y-3/13

(13,3)

Hope this helped!!

Factor to find the zeros of the function defined by the quadratic expression. 2x2 − 18x + 36 A) x = 3 or x = 6 B) x = 3 or x = −

Morgarella [4.7K]

Answer:

A) x=3 or x=6

Step-by-step explanation:

Factor out the GCF : 2(x^2-9x+18)

Then, set to zero.

2(x^2-9x+18)=0

2(x-3)(x-6)=0

x=3 or x=6
