Answer: the following system of equations has 2 solutions
x1=4
X2=-2
Step-by-step explanation:
5*x+4=x²+3*x-4
x²-2*x-8=0
x12=(2+/-√4+4*1*8)/2
x12=(2+/-√36)/2
x1=(2+6)/2=4
x2=(2-6)/2=-2
Answer:
y=-1/8x
Step-by-step explanation:
m=(y2-y1)/(x2-x1)
m=(-0.5-0.5)/(4-(-4))
m=(-1)/(4+4)
m=-1/8
y-y1=m(x-x1)
y-0.5=-1/8(x-(-4))
y-0.5=-1/8(x+4)
y=-1/8x-4/8+0.5
y=-1/8x-1/2+1/2
y=-1/8x
