Answer:
A, D, E . . . not a function
B, C . . . a function
Step-by-step explanation:
Look at the lists of first numbers:
{2, 3, 5, 2} . . . 2 is repeated, not a function
{3, -3, 0, 5} . . . no repeats, is a function
{1, 2, 3, 4} . . . no repeats, is a function
{4, 6, 8, 4} . . . 4 is repeated, not a function
{2, 2, 2, 2} . . . 2 is repeated, not a function
The graph of the function y = 3(x - 2)^3 + 7 is translated 2 units to the
right and then 4 units down. Write the equation of the final graph.
Answer:
y = 3(x - 4)^3 + 3Step-by-step explanation:
Given function
y = 3(x - 2)^3 + 7Translation to the right achieved by adding - 2 to x-value
Translation down achieved by adding -4 to y-value
So the function becomes:
y = 3(x - 2 - 2)^3 + 7 - 4 ⇒y = 3(x - 4)^3 + 3Plsss help!! Will give brainliest to the person with most explanation and best answer! 30 POINTS!

Which equation is correct?
Pls I need help !!!!!!
Answer: m1 m2 and m5 all equal to 135 as well
While m3 m6 and m4 are 45
Why: since they are on a line the two angles together should equal 180. So 180- 135= 45

Which is the graph of the equation ?
a
b
c
d
Answer:
First graph's equation is: y=2/3x+3
Second graph's equation is: y=2/3x-1
Third graph's equation is: y=2/3x+1
Fourth graph's equation is: y=2/3x-3
Step-by-step explanation:
Well you didn't provide the equation so I can't give you the exact answer but I can tell you the equation for each graph and you can match that with the equation they gave you!
Here ya go:
The y intercept is where the line crosses the y axis(vertical axis)
The slope is rise/run (vertical/horizontal)
The first graph:
The line crosses the y axis at (0, 3)
To find the slope we need to take the (y) of one of the given coordinates and subtract the (y) of the other coordinate then divide that over (x) of one of the coordinates minus the (x) of the other coordinate.
5-1/3-(-3)
4/6
2/3 is our slope, apply that to slope-intercept formula (y=mx+b)
y=2/3x+3
The second graph:
The line crosses the y axis at (0, -1)
Do as we did with the first graph to find the slope.
1-(-3)/3-(-3)
4/6
2/3 is our slope
y=2/3x-1
The third graph:
The line crosses the y axis at (0, 1)
Find the slope
3-(-1)/3-(-3)
4/6
2/3 is our slope
y=2/3x+1
The fourth graph:
The line crosses the y axis at (0, -3)
Find the slope
-1-(-5)/3-(-3)
4/6
2/3
y=2/3x-3

The next day, Kiran read for x minutes, and Andre read for 1/10 less than that. Write an equation that relates the number of minutes Kiran read with y, the number of minutes that Andre read.
Answer:
y - 1/10 = x
Step-by-step explanation:
y = # minutes read Kiran
x = # minutes read Andre
A farmer has a square field that is 1 mile wide by 1 mile long. Her irrigation system can water the northern 0.5 miles of her field. If her tomatoes are planted in a strip 0.3 miles wide, what is the area of her watered tomatoes?
Answer:
0.15mile^2Step-by-step explanation:
Step one:
Given
lenght of field L= 1mile
width of field W= 1 mile
Required
The area that can be watered
we are told that the system can water 0.5miles North
This represents the length that can be watered
and the width of the tomatoes area is 0.3miles
Therefore the area that can be watered is
A= 0.5*0.3
A=0.15mile^2
(ANSWER ASAP) Solve the inequality.
Answer:
y > -6
Step-by-step explanation:
add 6 over from the left side to get y by itself
this simplifies to -6
since this was subtraction, you flip the equation and the sign
so it changes to y > -6

Each bottle of perfume contains
2.1
2.1 fluid ounces of perfume. The store sells
30
30 bottles. How many fluid ounces of perfume did the store sell in total?
Answer:
Total amount of fluid sold = 63 ounces
Step-by-step explanation:
Given:
Each bottle contain = 2.1 ounces
Total number bottle = 30
Find:
Total amount of fluid sold
Computation:
Total amount of fluid sold = Each bottle contain x Total number bottle
Total amount of fluid sold = 2.1 x 30
Total amount of fluid sold = 63 ounces
Caleb and Landon work at a dry cleaners ironing shirts. Caleb can iron 30 shirts per hour, and Landon can iron 15 shirts per hour. Caleb worked 2 more hours than Landon and they ironed 330 shirts between them. Write a system of equations that could be used to determine the number of hours Caleb worked and the number of hours Landon worked. Define the variables that you use to write the system
Answer:
The system of the equations is x - y = 2, 2x + y = 22, where x is the number of hours that Caleb worked and y is the number of hours that Landon worked
Step-by-step explanation:
Assume that Caleb worked for x hours and Landon worked for y hours
∵ Caleb worked for x hours
∵ Landon worked for y hours
∵ Caleb worked 2 more hours than Landon
→ That means Caleb hours = Landon hours + 2
∴ x = y + 2
→ Subtract y from both sides
∴ x - y = 2 ⇒ (1)
∵ Caleb can iron 30 shirts per hour
∵ Landon can iron 15 shirts per hour
∵ They ironed 330 shirts between them
→ Multiply x by 30 and y by 15, then equate their sum by 330
∴ 30x + 15y = 330
→ Divide both sides by 15 to simplify the equation
∴ 2x + y = 22 ⇒ (2)
The system of the equations is x - y = 2, 2x + y = 22, where x is the number of hours that Caleb worked and y is the number of hours that Landon worked
Use the side-splitter theorem to solve for x in the triangle below.
Answer:
[tex] x = 7 [/tex]
Step-by-step explanation:
According to the side-splitter theorem, the two sides of the triangle is divided proportionally if the line that intersects both sides is parallel to the third side of the ∆.
Therefore, based on this theorem, we would have the following:
[tex] \frac{x}{21} = \frac{8}{24} [/tex]
Solve for x
[tex] \frac{x}{21} = \frac{1}{3} [/tex]
Multiply both sides by 21
[tex] \frac{x}{21}*21 = \frac{1}{3}*21 [/tex]
[tex] x = \frac{21}{3} [/tex]
[tex] x = 7 [/tex]
