Math help please I promise to give brainliest

AlekseyPX

Answer:

y = 0.5

x = 4 - y (0.5)

3.5 = 4 - 0.5

------------

3x - 10 = y

3(3.5) - 10 = y

10.5 - 10 = y

0.5 = y

Find the distance between the points (-16,-17) and (7,-17).

gladu [14]

Answer:

23 units

Step-by-step explanation:

Calculate the distance (d) using the distance formula

d = √ (x₂ - x₁ )² + (y₂ - y₁ )²

with (x₁, y₁ ) = (- 16, - 17) and (x₂, y₂ ) = (7, - 17)

d = $\sqrt{(7+16)^2+(-17+17)^2}$

= $\sqrt{23^2+0^2}$

= $\sqrt{23^2}$

= 23

Need help with 5e + 8f + (-2)e - 12f

Ivanshal [37]

You have to add your like terms. So you would add 5e + (-2)e first. That would equal 3e. Next you would add 8f + (-12)f. That would equal -4f. You final answer would be 3e - 4f.
