The correct answer is D
A, B, and C are not true because you can not have sides of a triangle that are negative numbers.

Answer:

The answer is the option D

$x=7, y=4$

Step-by-step explanation:

we know that

If the triangles are congruent

then

The corresponding sides are congruent

$AC=EF, BC=DE$

substitute the values

$5x-5y=2y+7$ -------> $5x=7y+7$ --------> equation A

$6y-8=2y+8$ -------> $6y-2y=8+8$ -------> $y=4$

Substitute the value of y in the equation A and solve for x

$5x=7(4)+7$

$x=35/5$

$x=7$

Umnica [9.8K]

Answer:

18.3 ( when EPS is 45 cents), otherwise there is none of these

Step-by-step explanation:

PE = Current Price / EPS

current Price = $ 8.22 = 822 cents

EPS = .45 cents (?) ... is it 45 cents ?

The standard form:

$Ax+By=C$

The slope-intercept form:

$y=mx+b$

m - slope

$m=\dfrac{y_2-y_1}{x_2-x_1}$

b - y-intercept (0, b).

We have the point (0, 43) → b= 43.

Next point (2, 55). Substitute to the slope formula:

$m=\dfrac{55-43}{2-0}=\dfrac{12}{2}=6$

Therefore we have:

$y=6x+43$ <em>subtract 6x from both sides</em>

$\boxed{-6x+y=43}$
