We move all terms to the left:

-9s-8-(-4s+8-3s)=0

We add all the numbers together, and all the variables

-9s-(-7s+8)-8=0

We get rid of parentheses

-9s+7s-8-8=0

We add all the numbers together, and all the variables

-2s-16=0

We move all terms containing s to the left, all other terms to the right

-2s=16

s=16/-2

s=-8

ABC is translated 4 unite to the loft and 8 unito up, thon roflooted
gayaneshka [121]

Answer:

(-3, 13)

Step-by-step explanation:

Coordinate of A is (7,5)

4 units to the left means (7-4, 5) --> (3,5)

8 units up means (3, 5+8) --> (3,13)

Reflected across the y-axis means that the sign of whatever x coordinate you have now will be reversed.

So (-3,13)

The sun shines at a 30° angle to the ground. To the nearest inch, how long is the shadow cast by a 72-in. tall fence post?
tensa zangetsu [6.8K]

The length of the shadow is 124.7 in

<u>Explanation:</u>

<u />

Given:

Angle, θ = 30°

Height of the fence,  h = 72 in

Length of the shadow, l = ?

Given:

tan 30° = \frac{perpendicular}{base}  = \frac{height of the fence}{length of the shadow}

\frac{1}{\sqrt{3} } = \frac{72}{l} \\\\l = 72\sqrt{3} \\\\l = 124.7 in

Therefore, the length of the shadow is 124.7 in
