Answer:
A
Step-by-step explanation:
Answer:
A) (4,8) is the correct answer.
Step-by-step explanation:
Step: Solvey=2xfor y:
y=2x
Step: Substitute2xforyiny=x+4:
y=x+4
2x=x+4
2x+−x=x+4+−x(Add -x to both sides)
x=4
Step: Substitute4forxiny=2x:
y=2x
y=(2)(4)
y=8(Simplify both sides of the equation)
Hope this helps!

A new amusement park presold discounted tickets for the opening day as well as upon arrival at the park the opening day ticket sales for the park including pre-sales is represented by this function where T(h) is the number of tickets sold H hours after opening at 7:00.am.
What is the approximate rate of change in the number of tickets sold between 10:00 a.m and 1:00 p.m?
HELP PLEASE I WILL MARK BRAINLIEST!!♥️
Answer:
-21 tickets per hour
Step-by-step explanation:
I think it's right
Answer:
Therefore, the correct answer is option C. 21 tickets per hour.
Step-by-step explanation:
Given: the opening day ticket sales for the park is given by the function[tex]T(h)=\frac{386+110h}{h}[/tex] where [tex]T(h)[/tex] represents the number of tickets sold [tex]h[/tex] hours after opening at 7:00 a.m.
To find: the rate of change in the number of tickets sold between 10:00 a.m and 1:00 p.m.
For 10 a.m., [tex]h=3[/tex]
So the number of tickets sold upto 10 a.m. are,
[tex]T(3)=\frac{386+110 (3)}{3}[/tex]
[tex]T(3)=238.67[/tex]
Similarly, for 1 p.m., [tex]h=6[/tex] hours
So, the number of tickets sold in 6 hours are,
[tex]T(6)=\frac{386+110(6)}{6}[/tex]
[tex]T(6)=174.33[/tex]
Now, the rate of change in the number of tickets sold between 10:00 a.m and 1:00 p.m is,
[tex]\frac{T(6)-T(3)}{6-3}[/tex]
[tex]=\frac{174.33-238.67}{3}[/tex]
[tex]=-21.445[/tex]
which is approximately [tex]-21[/tex] tickets per hour.
Hence, the rate of change in the number of tickets sold between 10:00 a.m and 1:00 p.m is -21 tickets per hour.
The correct answer is option C.

A block of marble is in the shape of a rectangular prism. The block is 2 feet long. 3 feet wide, and 90 inches high. What is the volume of the block? The volume of the block is cubic feet
Answer:
Volume of a rectangular prism can be found with the equation
v = length × width × height
They are trying to trip you up a little bit here because they give 2 measurements in feet then the last in inches. So for your prism...
18 inches = 1.5 ft
v = l×w×h
v = 3×2×1.5
v = 9 ft^3
Volume=length*width*height, so first you would have to change the units of the inches to feet, which would be 90/12=7.5, so now you can fit that into the equation, 2*3*7.5=45 ft cubed!
Choose the solution to this inequality.
The answer is c because 8-4is 4 and 3 (dominator) stays the same
Alexander is designing a new board game, and is trying to figure out all the possible outcomes. How many different possible outcomes are there if he flips a coin and rolls a fair die in the shape of a cube that has six sides labeled 1 to 6?
Answer:
its 24
Step-by-step explanation:
delta math said it was right
Answer is 12.
Possible Outcomes:
It is a list of all the resulting possibilities from an event.
(Here),
when he flips the coin, there are 2 outcomes = {front, back}
When he rolls a die, there are 6 outcomes = {1, 2, 3, 4, 5, 6)
For every outcomes of coin there are 6 outcomes of a die.
So, Possible outcomes = 2 * 6 = 12.

can someone help me on this?
Answer:
⅜ or ⅗
Step-by-step explanation:
I say ⅜ because of how many variables you can take into account 3 different colors, and a 2 sided coin, lastly 3 different numbers. So in total that is 8 possible variables and the 3 being blue, heads, and landing on 1.
Now I say ⅗ because of this perspective on the variables. You have the 3 colors, and your two sided coin but thing here is that the 1 is basically another color so the question is technically asking for the probability of spinning blue, landing on heads and landing on red in a sense.
