Harry is organizing a picnic. He can spend at most $24.00 on beverages. Iced tea costs $2.00 per gallon and lemonade costs $2.50

Arada [10]

Answer:

$10

Step-by-step explanation:

x + 5y = $24

x + 5($2.50) = $24

x + $12.50 = $24

x = $24 - $12.50

x = $11.50/2

x = 5

Thus, Harry bought 5 gallons of iced tea which cost him $10.

Aldo spends $14 each time he travels the toll roads. He started the month with $224 in his toll road account. The amount, A

skelet666 [1.2K]

Pare a.) $70 is what he would have left. Since each trip is $14 you would multiply that by the amount of times he went which was 11. 14x11 is $154. But you need what he has left so you take his total amount $224-$154 and get $70.

Part b.) 16 times. He has $224 total. You want to find out how many times he can go on the tool roads. We know the toll roads cost $14 each time. So you do $224/14 and get an even amount of 16. He would be able to use it 16 times before he have no money left.

Which of the following statements about f(x)=(x-4)^2-1 are true? select all that apply

melamori03 [73]

We have that
f(x)=(x-4)^2-1 in the question and f(x)=-(x-4)^2-1 in the picture
so

I'm going to analyze the two cases

using a graph tool

case 1)
f(x)=(x-4)^2-1
the vertex is the point (4,-1)
the x intercepts are the points (3,0) and (5,0)
the y intercept is the point (0,15)
the axis of symmetry is x=4
see the attached figure N 1

case 2)
f(x)=-(x-4)^2-1
the vertex is the point (4,-1)
there is no x intercepts
the y intercept is the point (0,-17)
the axis of symmetry is x=4
see the attached figure N 2

the answer
considering the case N 2 is
vertex (4,-1)------> is correct
y intercept (0,-17)-----> is correct
axis of symmetry x=4-----> is correct
