A system of equations consists of a line s of the equation y = x - 5 that is graphed in orange, and a line t that passes through
Zarrin [17]

ANSWER

x =  4

and

y =   - 1

EXPLANATION

Line s has equation:

y=x-5

And line t has equation:

y =  -  \frac{3}{4}x  + 2

We equate the two equations to get:

x - 5 =  -  \frac{3}{4} x + 2

Multiply through by 4

4x - 20  =  -  \frac{3}{4} x \times 4 + 2 \times 4

4x - 20  =  - 3 x  + 8

4x + 3x   =  8 + 20

7x=28

x =  \frac{28}{7}  = 4

y =  4  - 5 =  - 1

Given that g(x) = 2x ^ 2 - 2x + 8 , find each of the following. a) g(0) b) g(- 2) C) g(3) d) g(- x) e) g(1 - t)
raketka [301]

Answer:

g(-2)=20

Step-by-step explanation:

Given g(x)=2x^2-2x+8, substitute what is in the parentheses for x to find an output.

For g(-2), the term -2 is in the parentheses. Thus, substitute x=-2 into 2x^2-2x+8 to find g(-2):

g(-2)=2(-2)^2-2(-2)+8,\\g(-2)=2\cdot 4+4+8,\\g(-2)=8+4+8,\\g(-2)=\boxed{20}

Answer:

x=40

Step-by-step explanation:

Both angles are equal. So the equation needs to equal 156.

Just plug in points for x until the answer is 156.

In this case, when we plug in 40, it works!

(3*40)+36=156
