Y is the midpoint of line segment XZ. Find the length of XZ.

xz=60

Step-by-step explanation:

2(x+4) = 3x-3

2x+8 = 3x-3

8+3 = 3x-2x

11 = x

xz = 2(2(x+4))

xz = 4(11+4)

xz = 60

part a

x     y

0     8

1     7.5

2     7

3     6.5

4     6

5     5.5  

for every hour i deducted .5 inches from the length of the candle

part b

it is a function because for every x value there is only one y value

part   c

for every x value there is only one y value

x       y

step-by-step explanation:

2.2°  

step-by-step explanation:

let θ = the angle of elevation.

tanθ =77/2020

tanθ = 0.038 12

      θ = tan⁻¹0.038 12

      θ = 2.2°
