Answer:
$1040
Step-by-step explanation:
9 ÷ 100 = 0.09 × 500 = 45
45 × 12 = 540
500 + 540 = 1040
Replace x with the value in the answers and solve for Y to see which ones match.
y = 1-4 = -3
y = -1-4 = -5
(1,-3), (-1,-5) is the answer.
(2x-1)(4x+1) just multiply the terms in the parentesis
Do the following:
2x*4x
2x*1
-1*4x
-1*1
You get:
8x^2+2x-4x-1
Final result:
8x^2-2x-1
