(1,-9)
Step-by-step explanation:
Rewrite in vertex form and use this form to find the vertex
(h,k).
Answer:
(f-g)(4) = 10
Step-by-step explanation:
(f-g)(x) = f(x) - g(x)
= 1/2 x^2 - 1/4 x + 4 - 1/2 x + 1
= 1/2 x^2 - 1/4 x - 1/2 x + 4 + 1
= 1/2 x^2 - 3/4 x + 5
(f-g)(4)
= 1/2 (4)^2 - 3/4 (4) + 5
= 1/2 * 16 - 3 + 5
= 8 - 3 + 5
= 5 + 5
= 10
First
bring the fractions to a like denominator
8/12 equals 2/3 and 9/12 is equal to 3/4
2nd
cut the 8/12 into fourths
so 2/12 each piece
jessica ate 3 of the fourths so she ate
6/12 of the leftovers so it's half of the leftovers
now lets just cut up the pizza into 36. and 2 thirds is equal to 24/36
jessica ate 6/12 so she ate 12/24 of that
jessica ate 1/3 of the pizza
Answer:
300 burgers
Step-by-step explanation:
You can set up an equation like this: 50+0.05x=20+0.15x
Then, subtract 0.05x from both sides: 50=20+0.10x
Subtract 20 from both sides: 30=0.10x
Divide by .10 on both sides: 300=x
X represents how many burgers must be sold for the boys to have earned the same amount of money, and that is 300 burgers.
