What is the solution to the system of equations? y = 2x – 3.5 x – 2y = –14 (–7, 3.5) (3.5, –7) (7, 10.5) (10.5, 7)

Putting the first equation into the second equation, we have

x - 2(2x - 3.5) = -14

x - 4x + 7 = -14

-3x = -21

x = 7

y = 2(7) - 3.5 = 14 - 3.5 = 10.5

Therefore the solution is (7, 10.5)

Step-by-step explanation:

the formula of a slope:

from a table we have

substitute:

the slope of f(x) is -1.

the graph of funcfion g(x) is a horizontal line. the slope of a horizontal line is equal 0. therefore the slope of g(x) is 0.

-1 < 0

1. sometimes

2. never true

3. sometimes

step-by-step explanation:

these are pretty self explanatory if you know what supp right and com angles are
