Answer:
Step 1: Find f(5/2)
f(5/2) = -23(5/2) + 5
f(5/2) = -115/2 + 5
<em><u>f(5/2) = -105/2</u></em>
<em><u /></em>
<em><u /></em>
Step 2: Find f(52)
f(52) = -23(52) + 5
f(52) = -1196 + 5
<em><u>f(52) = -1,191</u></em>
I don't know how to solve 11 but I guess I can solve 12 so I think those are the answers:
12.
(4, 53)
(5, 85)
Answer:
(8x - 5y)(8x + 5y)
Step-by-step explanation:
To factor the expression, use the difference of squares pattern. A difference of squares is subtraction between two perfect squares and factors as a² - b² = (a-b)(a+b).
The expression has the perfect squares 64x² and 25y². Take the square root of each. The factors become (8x - 5y)(8x + 5y).
From what I can see with this picture, it seems like theyre asking for percentages of one number, to take a percentage of a number you convert the percent to a decimal, so 10% is equal to 10/100 = .10, so 200 * .10 = 20
P (perimeter)= (5x-7) + (3x-4) + (2x-6)
P= (5x+3x+2x) + (-7-4-6)
P= 10x-17
