Given EGF~HGI what is the value of x

saveliy_v [14]

Answer:

$x = 14$

Step-by-step explanation:

Since ∆EGF is similar to ∆HGI, therefore, the ratio of their corresponding side lengths are the same.

Thus, FG:GI = EG:GH

FG = x + 4

GI = 30

EG = 12

GH = 20

$\frac{FG}{GI} = \frac{EG}{GH}$

$\frac{x + 4}{30} = \frac{12}{20}$

Cross multiply

$(x + 4)(20) = (12)(30)$

$20x + 80 = 360$

Subtract 80 from both sides

$20x + 80 - 80 = 360 - 80$

$20x = 280$

Divide both sides by 20

$\frac{20x}{20} = \frac{280}{20}$

$x = 14$

Has a slope of -2/5 and goes through (-10,-1)

Aleonysh [2.5K]

Answer:

Below in bold.

Step-by-step explanation:

Using the point-slope form of a straight line equation:

y - y1 = m(x - x1)

y - (-1)) = -2/5(x - -10)

y + 1 = -2/5(x + 10)

y + 1 = -2/5x - 4

y = -2/5x - 5.

In standard form this is:

2x + 5y = -25.
