Pllllssss help i dont need working out just answers

A) y = -(8/3)m - 2

B) y = 4x - 1

C) y = -3.2x - 4

D) y = -2.5x - 3

Step-by-step explanation:

A) In the first equation, when x = 0, y = -2

From y = mx + c, we can say that

-2 = 0 + c

c = -2

Also,when y = 0, x = -0.75

Thus, 0 = -0.75m - 2

m = -2/0.75 = -8/3

Thus, y = -(8/3)m - 2

B) when x = 0, y = -1

From y = mx + c, we can say that

-1 = 0 + c

c = -1

Also,when y = 0, x = 0.5

Thus, 0 = 0.5m - 2

m = 2/0.5 = 4

y = 4x - 1

C)when x = 0, y = -4

From -4 = mx + c, we can say that

-4 = 0 + c

c = -4

Also,when y = 0, x = -1.25

Thus, 0 = -1.25m - 4

m = - 4/1.25 = -3.2

y = -3.2x - 4

D) when x = 0, y = -3

From y = mx + c, we can say that

-3 = 0 + c

c = -3

Also,when y = 0, x = -1.2

Thus, 0 = -1.2m - 3

m = -3/1.2 = -2.5

y = -2.5x - 3

The diagram I attached is this triangle based on the information you gave. From the information, we know a few things that can help us solve the problem.
(You should know that a triangle has 180°, as well.)

First: We know that m∠A = 20°. We know that m∠B = m∠C. And finally, we know that m∠A + m∠B + m∠C = 180. Since m∠B = m∠C, we can substitute one for the other. Let's say that m∠B = x, just for clarity's sake. We end up with:
20 + 2x = 180
2x = 160
x = 80°
This means that m∠B and m∠C = 80°.

To solve for AC, we can use the Law of Sines (which is ). Substitute 20 for A, 4 for a, 80 for B, and AC for b.

Cross-multiply:

Divide both sides by .

And finally, solve:
