Answer:
110.8. This is only for 24÷5 +18-12-400+500. I don't know the answer to the last two numbers.
Step-by-step explanation:
Answer:
b) $4.60
Step-by-step explanation:
a)
2 panels at $923.40 each = $1846.80
Total with installation: $1944.80
Installation $1944.80-$1846.80 = $98
b)
2 panels at $940.50 each = $1881.00
Total with installation: $1983.60
Installation $1983.60-$1881.00 = $102.60
Substract a from b
102.60-98 = 4.60
A and C appear to be 5th degree polynomials
Answer:
2 solutions:
x=5 and y=7
x=-1 and y=-5
Step-by-step explanation:
y=2x-3
y=x^2-2x-8
y=y so:
2x-3=x^2-2x-8
simplifying to:
x^2-4x-5=0
factoring to:
(x-5)(x+1)=0
x=5 or x=-1
if x=5 then y=2(5)-3=7
if x=-1 then y=2(-1)-3=-5
