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:
Step-by-step explanation: okay so given the radius, u find the circumference of the circle (2*pi*radius). Divide 48 by 360 and then multiply that result by the circumference because your finding the length of only a portion of the circle.
Step-by-step explanation:
where n starts from 0.
so the answer is :
16+5=21,
25+7= 32
C(-1,4),(1,7),(2,10) hope this helps
