The correct answer is summer because of heat
I only know what in the picture which is the letter A
(2x+1)(x+5) is the answer.
Answer:
2x+y=15x+y=10
Consider the first equation. Subtract 15x from both sides.
2x+y−15x=y
Combine 2x and −15x to get −13x.
−13x+y=y
Subtract y from both sides.
−13x+y−y=0
Combine y and −y to get 0.
−13x=0
Divide both sides by −13. Zero divided by any non-zero number gives zero.
x=0
Consider the second equation. Insert the known values of variables into the equation.
15×0+y=10
Multiply 15 and 0 to get 0.
0+y=10
Anything plus zero gives itself.
<span>ax + by + c = 0
by = - ax - c
y = -a/b (x) - c/b
so slope = </span>-a/b
answer
-a/b
