The answer is x=-80.

First subtract 4 from both sides.

-6= $\frac{x}{8}$ +4

-6-4= $\frac{x}{8}$ +4-4

-10= $\frac{x}{8}$

Multiply 8 on both sides to isolate x.

-10·8= $\frac{x}{8*8}$

-80=x

Triangle JKL and triangle MNP are similar.

Rom4ik [11]

Answer:

Option G

Step-by-step explanation:

We know that both triangles are similar in proportion. We see that the base of 8 is similar to 6, and therefore the side length of x should be similar to 5.

x/5 = 8/6

Cross multiply.

6x = 40

x = 40/6

x = 6 + 2/3

x = 6.67

13x - 5y (if x = 10 and y = 6)

OlgaM077 [116]

Answer:

13(10) - 5 (6)

130 - 30

= 100

Step-by-step explanation:

You replace the x with 10, and the y with 60 and answer normally

13(30) = 130

5(6) = 30

130 - 30 = 100

What is the solution of the system?<br> y=x^2-4x+5<br> Y=-2+8

Nataly_w [17]

Yea something is not right.if y=6 then you cant solve the system because you end up with x^2-4x-1

Solve for x & y. 30x−42y=−6 and 5x−7y=−1

vladimir1956 [14]

Um.. Both of those equations are the exact same. Divide both sides of the first equation by 6. You get:

$\frac{30x - 42y}{6} = \frac{-6}{6} \\ 5x - 7y = -1$

That is the exact same as the second equation. This system has an infinite number of solutions. 5x - 7y = -1 is a line, so basically every point on that line is a solution to the system.

For example, $x = 0$ and $y = \frac{1}{7}$ would work, but so would $x = 1$ and $y = \frac{6}{7}$
