1 answer:
Mandarinka [93]3 years ago
5 0

Answer:

(-2,2)

Step-by-step explanation:

x+2y=2 and 7x-3y=-20

x+2y=2

-2y    -2y

7(-2y+2)-3y=-20

-17y+14=-20

-14          -14

-17y=-34

^divide both sides by -17

y=2

x(-2)(2)+2

x=-2

Identifying Slope and y-Intercept of a Line
Ira Lisetskai [31]

Step-by-step explanation:

The slope-intercept form of an equation of a line:

y = mx + b

m - slope

b - y-intercept

y = 1 - 3x = -3x + 1

slope = -3

y-intercept at 1

y = 3x - 1

slope = 3

y-intercept at -1

x - 3 = y → y = 1x - 3

slope = 1

y-intercept at -3

x + 3 = y → y = 1x + 3

slope = 1

y-intercept at 3

HELLPPPPPPPPPPP PLEASE
KiRa [710]
Alright, so we plug (-2) in for x. (-2)^2 =4, and we can plug that in as 4(4)+(-2)+5. Next, 4*4=16, so we get 15+(-2)+5. After that, we get 15-2+5=18

Does anyone know this
Tamiku [17]

Answer:

I belive the answer is A

Step-by-step explanation:

So any answer with 22t would make sense, so you have A and C. In C though, it is subtracting 22, but since 6195 is the total it would have to include the 22 so it is A.
