1. Find the value of x.

Mathematics
1 answer:
Kisachek [45]2 years ago
4 0

Answer:

x = 14

Step-by-step explanation:

Assuming the triangles are similar then the corresponding sides are in proportion, that is

\frac{15}{x-4} = \frac{12}{8} = \frac{3}{2} ( cross- multiply )

3(x - 4) = 30 ( divide both sides by 3 )

x - 4 = 10 ( add 4 to both sides )

x = 14

Can someone help me find an equation for both of these ❤️
Nitella [24]

Answer and Step-by-step explanation:

<u><em>First equation:</em></u>

y = -4x + 9

This equation has a negative slope (a slope that does downwards) and has a positive y-intercept (at (0, 9)).

<em><u>Second Equation:</u></em>

y = -4x - 4

This equation is parallel to the first line because it has the same slope. It also has a negative y-intercept (at (0, -4)).
