26,500 - 19,610 = 6,890
6,890 would be your price discount, but now you'd have to find your percent discount. Make it into an equation to make things easier.
6,890/26,500 = p/100
(6,890*100)/26,500 = p
6,890*100 = 689,000
689,000/26,500 = 26
The price discount would be 26%.
D All real numbers Equal or greater that 2
Step-by-step explanation:
Root of the function, where y = 0
f(x) = x² + 2x - 1
0 = x² + 2x - 1
x² + 2x - 1 = 0
x² + 2x = 1
x² + 2x + 1 = 1 + 1
(x + 1)² = 2
x + 1 = ±√2
x = -1 ± √2
Roots → x = -1 ± √2
Answer:
C. x^2 -4
Step-by-step explanation:
What you do is subtract the functions as said by
(f-g)(x).
so:
f(x)-g(x)
(2x^2+3) - (x^2 -7)
2x^2 -x^2 +3 - 7= x^2 -4
Ok, so she started off with $5.00.
She bought milk for $2.99.
She buys bread, which costs $1.50.
Subtracting the money she wasted, the total would be $0.51.
The only thing she could buy is 5 pieces of gum for 25 cents.
Her change will be $0.26.
Hope this helps!
