C. Plumber A and Plumber B will both charge $135 if they each work 2.5 h.
M1 = m4 = 50 (A) is the answer
First, make sure you convert both equations into standard form. Your two equations would be 2x+2y=38 and -x+y=3. Then multiply the bottom by 2. So your new equations would be 2x+2y=38 and -2x+2y=6. The x would cancel out and you would continue solving for y. y would equal 11 and then you would plug it back into an original equation. When you plug and solve for x, you would get x=8. So your answer would be (8,11)
Answer:
A vector's magnitude represents its length, so your answer is C, the length of a vector.
