Answer:
24 - 24 = 0 (carols age past tense)
24 x 4 = 96
96 - 24 = 72 (present tense)
carol is now 72 yr
Answer: 1/2
First you do 4/4 times 4/4. Which is equal to 1. Then, you multiply by 2/4 to get 1/2.
Answer:
-3+-4
Step-by-step explanation:
David sold 60 bottles and Sammy sold 100 bottles. x(5+3)=160; 5x+3x=160; 8x=160; 8x/8=160/8; x=20; 20(5+30); 100+60=160
Answer:
See below
Step-by-step explanation:
y = -6x^2 + 24x-100
solve for 'x'
y + 100 = -6x^2 + 24x = -6(x^2-4x) complete the square for x
(y+100) /(-6 ) = (x-2)^2 -4 add 4 to both sides
(y+100)/(-6) +4 = (x-2)^2 sqrt both sides
sqrt [ ( y+100)/(-6) + 4 ] + 2 = x change x and y
y = ± sqrt [ (x+100)/(-6) + 4 ] + 2 simplify (if needed)
<u>y = ± sqrt( -x/6 -12.666) + 2 </u>
