Answer:

y= -2

Step-by-step explanation:

ADDING BOTH EQUATIONS

-3y + 51 =26

-<u>2y -51  = -16</u>

-5y        =  10

-5y/5 =  10/5

-y =2

y = -2

Please find the slope of (-2, 4) and (3, -5)
DIA [1.3K]

Answer:

The slope of the line = m = -9/5

Step-by-step explanation:

Given the points

  • (-2, 4)
  • (3, -5)  

Determining the slope between (-2, 4) and (3, -5)

(x₁, y₁) = (-2, 4)

(x₂, y₂) = (3, -5)

Using the formula

Slope = m =  [y₂ - y₁] /  [x₂ - x₁]  

                 =  [-5 - 4] / [3 - (-2)]

                 = [-9] / [3 + 2]

                 = -9/5

Thus, the slope of the line = m = -9/5

Answer correctly please !!!!!!!!!!!!!! Will mark brainliest !!!!!!!!!!!!!!!!!!!
valina [46]

Answer:

74º

Step-by-step explanation:

  • Ray TV bisects ∠RTS, so ∠RTV=∠STV=(16x-6)º
  • We also know that ∠RTS=(26x+18)º
  • So, (16x-6)º+(16x-6)º=(26x+18)º
  • We don't need parenthesis, 16x-6+16x-6=26x+18
  • Combine like terms, 32x-12=26x+18
  • Add, 32x=26x+30
  • Subtract, 6x=30
  • Divide, x=5
  • ∠RTV now is [16(5)-6]º=(80-6)º=74º
