Step-by-step explanation:
y=6x^2-5x+1
y=-2x+4
<em>Substitute</em>
-2x+4=6x^2-5x+1
<em>Simplify</em>
0=6x^2-3x-3
<em>Solve by factoring</em>
(x-6/6)(x+3/6)=0
x-1=0, x+1/2=0
x=1, x=-1/2
<em>Plug x's into oringinal equation</em>
y=-2(1)+4, y=-2(-1/2)+4
y=-2+4, y=1+4
y=2, y=5
<em>Write out solutions</em>
(1,2) and (-1/2,5)
Answer: c
Step-by-step explanation:
Answer:
x=−5
Step-by-step explanation:
−3x+5=20
Step 1: Subtract 5 from both sides.
−3x+5−5=20−5
−3x=15
Step 2: Divide both sides by -3.
−3x/-3 = 15/-3
