Answer:
x=2.5, y=6.5
Step-by-step explanation:
Y=x+4 ,y=3x-1
x+4=3x-1
2x=5
x=2.5
y=x+4=2.5+4=6.5
0.625 = 0.625 / 1
Numerator = 0.625 × 10 × 10 × 10 = 625
Denominator = 1 × 10 × 10 × 10 = 1000
Numerator / Denominator = 625 / 1000
Our simplifed fraction is:
= 625/1000
= 5/8
I think it would be A. It controls how much we pay for goods and services, because if there is a high demand, and a limited supply, the cost will be high, if there is a large supply but low demand, then the cost will be lower.
Answer:
D
Step-by-step explanation:
substitute 10 for x in the equation and solve
If the roots are r1,r2,r3, the facotred polynomail looksl ike this
f(x)=(x-r1)(x-r2)(x-r3)
given
roots 4,2i and -2i
f(x)=(x-4)(x-2i)(x-(-2i))
f(x)=(x-4)(x-2i)(x+2i)
expand
f(x)=x³-4x²+4x-16
