Answer:

x=5 so x+1 = 6 and x+3 = 8

Step-by-step explanation:

It's all about proportions. These are similar triangles, so corresponding sides are proportional. Basically you want to solve an equation $\frac{x+1}{x+3} = \frac{3}{4}$

Let me know if you cannot see how EG corresponds to GH or how EF corresponds to IH.

Anyway, from here we just solve. Again, let me know if you have any questions.

4(x + 1) = 3(x + 3)

4x + 4 = 3x + 9

x = 5

And you can check

[tex]\frac{6}{8} = \frac{3}{4}[/tex

Answer:

−(7p+6)−2(−1−2p) = - 3p - 4

Step-by-step explanation:

−(7p+6)−2(−1−2p) = -7p - 6 + 2 + 4p

= (-7p + 4p) + (2 - 6)

= -(7p - 4p) - (6 - 2)

= - 3p - 4

Which equation shows how (-10,8) can be used to write the equation of this line in point-slope from?

NeTakaya

Options :

y – 8 = –0.15(x – 10)

y + 8 = –0.15(x – 10)

y – 8 = –0.2(x + 10)

y + 8 = –0.2(x – 10)

Answer:

y – 8 = –0.2(x + 10)

Step-by-step explanation:

(-10, 8)

General equation in point - slope form:

y - y1 = m(x - x1)

m = slope

Given the points : ( - 10, 8)

x1= - 10 ; y1 = 8

y - y1 = m(x - x1)

Substitute the values of x and y into the equation :

y - 8 = m(x - - 10)

y - 8 = m(x + 10)

The best option which fits is :

y – 8 = –0.2(x + 10)
