The x table increases by a constant amount, 1. While the y table increases by different amounts, making it not a function.
also if you graphed this, it would not be a line, making it not a function.
Hope this helped!! :)
Answer:
function
Step-by-step explanation:
To be a function, each value of the x-coordinate can be used only once. In other words, all x-coordinates must be different.
Here, the x-coordinates are all different, so it is a function.

If tan(t) ≈ 2.7, and sin(t) ≈ 0.94, find cos(t)
Answers
Answer:
cos = 0.89/1.9 = 0.46842105263157895-
Step-by-step explanation:
the value of cos(t) is approximately 0.347.
To find the value of cos(t), we can use the identity:
tan²(t) + 1 = sec²(t)
Since we know the value of tan(t) is approximately 2.7, we can calculate sec(t):
sec²(t) = tan²(t) + 1
sec²(t) = 2.7² + 1
sec²(t) = 7.29 + 1
sec²(t) = 8.29
Now, to find sec(t), we take the square root of both sides:
sec(t) = √(8.29)
sec(t) ≈ 2.877
Finally, we can find cos(t) using the reciprocal identity:
cos(t) = 1 / sec(t)
cos(t) ≈ 1 / 2.877
cos(t) ≈ 0.347
So, the value of cos(t) is approximately 0.347.

Sixteen scholars have volunteered to stay after school to help set up for the school musical. The musical director plans to order pizza for the scholars. Each pizza pie includes 8 slices and costs $13.49. How much money would the director have to pay in order to give each scholar 1.5 slices of pizza?
Answers
If each scholar eats one slice of pizza, then there would be two pizza pies because 8 slices plus another 8 slices in 16
8+8=16
If all of them eat another .5 slice, adding up the halves would equal 8
.5 x 16 = 8
In total, the director would have to buy three pizzas which equals up to our total of $40.47

Tim earns spending money by doing odd jobs for his neighbors. The table shows how much he is paid
for each job. Tim gets $12 for mowing lawn, $9 for washing cars, and $7 for walking dogs. Tim owes his mother $23. What possible combination of jobs could Tim perform to earn
enough money to pay back his mother? Write an addition equation using integers to represent the
situation. Will he have money left over? Select the correct choice below and fill in the answer boxes to complete your choice.
Answers
Answer:
D
Step-by-step explanation:
D is the only option where Tim has 23 or more dollars earned.
To show this I will solve each equation...
A) (-23)+9+9 = (-23)+18= -5
-5 < 0 so A doesn't work
B) (-23)+7+7+7 = (-23)+21= -2
-2 < 0 so B doesn't work
C) (-23)+12+9 = (-23)+21= -2
-2 < 0 so B doesn't work
D) (-23)+12+12 = (-23)+24= 1
1 > 0 so D does work!
* I am using 0 to compare each number with the result because Tim should have 0 or more dollars after paying his mom.

Answer:
F=(9C+160)/5
Step-by-step explanation:
C=5(F-32)/9
Simplify to 5F-160/9=c
multiply by 9 on both sides : 5F-160=9C
add 160 to both sides: 5F=9C+160
Divide by 5 on both sides: F=(9C+160)/5
Simplify: F=9/5c+32
Answer:
[tex]F=\frac{9C}{5}+32[/tex]
Step-by-step explanation:
The subject of the formula is the variable that's being worked out. Originally this was C. They want us to make F the subject of the formula.
[tex]c=\frac{5(F-32)}{9}[/tex]
To do this we first need to distribute 5.
[tex]C=\frac{5F-160}{9}[/tex]
Divide 5F-160 by 9.
[tex]C=\frac{5}{9}f-\frac{160}{9}[/tex]
We can then swap sides to make it easier.
[tex]\frac{5}{9}f-\frac{160}{9}=C[/tex]
We then add [tex]\frac{160}{9}[/tex] to each side.
[tex]\frac{5}{9}f=c+\frac{160}{9}[/tex]
We can then find F by multiplying by 9/5 or dividing by 5/9.
[tex]F=\frac{9}{5}(C+160/9)[/tex]
We then can simplify by multiplying.
[tex]F=\frac{9C}{5}+32[/tex]

−12x−8y−12x−30y
