Substitute x with (-2) and y with (-4)<br> Simplify: 5(41 - x) + {-7(y + x)} =

kkurt [141]

Answer:

$257$

Step-by-step explanation:

We want to evaluate:

$5(41 - x) + ( - 7(y + x)$

for x=-2 and y=-4.

We substitute to get:

$5(41 - - 2) + ( - 7( - 4 + - 2)$

We now simplify to get:

$5(41 + 2) - 7( - 6)$

$5 \times 43 + 42$

$215 + 42 = 257$

If EF bisects CD, CG = 5x-1, GD = 7x-13, EF=6x-4, and GF = 13, find EG (MUST SHOW WORK)

iogann1982 [59]

Answer:

EG = 19

Explanation:

Given that a line segment CD. EF bisects the line CD at point G.

Length of CG = 5x-1

Length of GD = 7x - 13

We know that CG = GD

5x-1 = 7x-13

Solve for x,

2x = 12

x = 6

Now given that,

EF = 6x-4

GF = 13

EF = EG + GF

6x - 4 = EG + 13

EG = 6x - 4 - 13

EG = 6x - 17

put the value of x = 6, in order to find the EG

EG = 6*6 - 17

EG = 19

That's the final answer.

I hope it will help you.
