eliminating y
x - y = -5
3x + y = 1
________ +
4x = -4
x = -1
eliminating x
• x - y = -5 ....... (x3)
3x + y = 1 ....... (x1)
• 3x - 3y = -15
3x + y =1
___________ -
-4y = -16
y = 4
A. (-1, 4)
Answer:
Option B is correct.
Step-by-step explanation:

Answer:
slope of 2y- 5X = -20: m=
Convert to standard form: 5x- 2y=20
Slope using standard form: m=5/2
slope - Intercept form of 2y-5x= -20:
y=mx+b
y=5/2x-10
Axis interception points of 5/2x-10:
X Intercepts: (4, 0),
Y Intercepts: (0, - 10)
I don’t think you’re wrong good job
Answer:
(12x²+4)(x-5)
Step-by-step explanation:
To factor the expression factor by grouping.
(12x³ - 60x²) + (4x - 20)
12x²(x - 5) 4(x-5)
(12x²+4)(x-5)
