Solve the system of equations by the substitution method.

Mathematics
1 answer:
victus00 [196]3 years ago

Answer:

Step-by-step explanation:

Are you certain you wrote the question accurately?—because none of the choices is correct.

rearrange 3x+y =-5 to solve for y:

y = -3x-5

substitute -3x-5 for y into the second equation:

12x + 3y = 13

12x + 3(-3x-5) = 13

12x - 9x - 15 = 13

3x = 28

x = 28/3

y = -3x-5 = -33

solution: (28/3, -33)

frez [133]
(1/2,3)(2,3/4)
slope = (3/4 - 3) / (2 - 1/2) = (3/4 - 12/4) / (4/2 - 1/2) =
(-9/4) / (3/2) = -9/4 * 2/3 = -18/12 = -3/2

<h3>Answer: Choice 2)  sin(B) = cos(90-B)</h3>

Explanation:

The rule is that

sin(A) = cos(B)

if and only if A+B = 90.

Solving for A gets A = 90-B

So we end up with

sin(90-B) = cos(B)

which is the same as

cos(B) = sin(90-B)
