Will give brainiest

Mashutka [201]

Answer:

Step-by-step explanation:

We are told that n = 3m + 6. Substitutte 3m + 6 for n in the second equation, obtaining:

(3m + 6) - 2m = 2, or 3m + 6 - 2m = 2.

Combining like terms yields

m = -4.

Knowing that m = -4 allows us to calculate n. Use the first equation, n = 3m + 6, for this purpose: n = 3(2) + 6 = 12.

Thus, the solution is (2, 12).

Find the value of 13 + (-7)

Vikki [24]

Answer:

Step-by-step explanation:

Before solve this you've to know that,

( + ) × ( - ) = ( - )

( + ) × ( + ) = ( + )

( - ) × ( - ) = ( + )

Let us solve now.

13 + (-7)

13 - 7

= 6

Hope this helps you :-)

Let me know if you have any other questions :-)

Consider the point P = (4,-1) and the line L, given by the equation y=2x+3.

3241004551 [841]

Answer:

A. y=2x-9

B. $y=-\frac{1}{2}x+1$

Step-by-step explanation:

A. Parallel lines have the same slope. That means the line y=2x+3 has the same slope as any line parallel to it. So the slope is 2.

Using m=2, substitute it and (4,-1) into the point slope form and simplify to find the y-intercept.

$y-y_1 = m(x-x_1)\\y--1=2(x-4)\\y+1=2(x-4)\\y+1=2x-8\\y=2x-9$

B. Perpendicular lines have slopes which are negative reciprocals of each other. The slope of the line y=2x+3 is 2. The slope perpendicular to it is -1/2.

Using m=-1/2, substitute it and (4,-1) into the point slope form and simplify to find the y-intercept.

$y-y_1 = m(x-x_1)\\y--1=-\frac{1}{2}(x-4)\\y+1=-\frac{1}{2}(x-4)\\y+1=-\frac{1}{2}x+2\\y=-\frac{1}{2}x+1$
