And is C
Caitlin can eliminate $54 from Food/Clothes and $120 from Entertainment.
The choices are points of a function that lies at coordinates (x,y). Just do trial and error with each choice and see which applies
a) x = 0, y = 0
-5(0)^2 + 20(0) - 17 > 0
-17 > 0 (not true)
b) x = 2, y= 2
-5(2)^2 + 20(2) - 17 > 2
3 > 2 (true)
c) x =5, y=2
-5(5)^2 + 20(5) - 17 > 2
-42 > 2 (not true)
d.) x=1, y=5
-5(1)^2 + 20(1) -17 > 5
-2 > 5 (not true)
So, the answer is B.
Answer:
i can not see the picture..
Step-by-step explanation:
Answer:
x = -4/5 or x = 71/8
Step-by-step explanation:
Solve for x:
(5 x + 4) (8 x - 71) = 0
Split into two equations:
5 x + 4 = 0 or 8 x - 71 = 0
Subtract 4 from both sides:
5 x = -4 or 8 x - 71 = 0
Divide both sides by 5:
x = -4/5 or 8 x - 71 = 0
Add 71 to both sides:
x = -4/5 or 8 x = 71
Divide both sides by 8:
Answer: x = -4/5 or x = 71/8
The answer is A, pi. (Sorry I don’t have three pi symbol on my phone.)
