Answer:

hi there!

the answer to this question is x= 7

Step-by-step explanation:

you minus 6x on both sides to get 2x+5=19

then you minus 5 on both sides to get 2x=14

then you divide 2 on both sides to get x=7

Which of the following equations has the same solution as m - (-62) = 45?

Alborosie

Well in the first equation m= -17
So you just have to substitute -17 in and see if it makes sense
like with the first equation -17 + 25 does equal 8 therefore x (in the second equation) = m (in the first)

15 POINTS! What is the correct answer for Dean's problem? Explain where he went wrong.

prohojiy [21]

Answer:

The slope is 5/-2.

Step-by-step explanation:

Slope is y1-y2 over m1-m2 (rise over run). The first ordered pair is -2 (m1) and 11 (y1). We then subtract the second ordered pair (4 (m2) and -4 (y2)) from the first.

11 - (-4) = 11 + 4 = 15

-2 - 4 = -6

Remember, slope is rise over run (y over x), so the slope is 15/-6. Now, we must simplify. 15/-6 = 5/-2

Dean went wrong because he thought that slope was run over rise (x over y). If he had switched the two numbers, his answer would have been correct.
