Answer:38x-34
Step-by-step explanation:
f(x)=x^2+3x-7
g(x)=5x-3
We multiply the entire F equation times two, (x^2+3x-7)*4=
(4x^2+12x-28)
Now the entire g equation by 2, (5x-3)*2
(10x-6)
Now we add both equation
(4x^2+12x-28)+(10x-6)
(4x^2+22x-34)
(4x*4x+22x-34)
(16x+22x-34)
38x-34
Hopefully this is correct :)))
Answer:
$19.55
Step-by-step explanation:
Discount = 15% of 21.50
= 0.15 * 21.50
= 3.225
= $ 3.23
Balance need pay = 21.50 - 3.23 = $ 18.27
Tax = 7% of 18.27
= 0.07 * 18.27
= $1.28
Balance with tax = 18.27 + 1.28 = $ 19.55
