Answer:

point-slope form:

y - 10 = -4(x - -2)

y - 10 = -4(x + 2)

---

slope-intercept form:

y - 10 = -4x - 8

y = -4x - 8 + 10

y = -4x + 2

Solve for . 5w-26=-4(w-7) Simplify your answer as much as possible. PLZ HELP

NikAS [45]

Answer:

w = 6

Step-by-step explanation:

5w-26 = - 4 (w - 7) multiply -4 through

5w - 26 = - 4w + 28 add 4w to each side to cancel it out on the right

5w + 4w - 26 = 28

9w - 26 = 28 Now add 26 to each side

9w - 26 + 26 = 28 + 26

9w = 54 Now divide each side by 9

(9w)/9 = 54/9

w = 6

If A = (7,9) and B = (3 , 12) what is the length of AB

V125BC [204]

Answer:

AB = 5 units

Step-by-step explanation:

Calculate the length using the distance formula

d = $\sqrt{(x_{2}-x_{1})^2+ (y_{2}-y_{1})^2$

with (x₁, y₁ ) = A(7, 9) and (x₂, y₂ ) = B(3, 12)

AB = $\sqrt{(3-7)^2+(12-9)^2}$

= $\sqrt{(-4)^2+3^2}$

= $\sqrt{16+9}$

= $\sqrt{25}$

= 5

PLEASE HELP! IM ALMOST DONE WITH THIS ASSIGNMENT PLSSS HELPP ILL GIVE BRAINLIEST SHOW UR WORK

Talja [164]

Answer:

x = -3

y = -8

Step-by-step explanation:

2y = x - 13

3x = y - 1; let y = 3x + 1

substitute to solve for 'x':

2(3x + 1) = x - 13

6x + 2 = x - 13

5x + 2 = -13

5x = -15

x = -3

solve for 'y':

3(-3) = y - 1

-9 = y - 1

-8 = y
