Answer: All x-coordinates are different, so this relation is a function.
Having the same y value more than once is not a problem for a function.
"This (does not/does) represents a function because different (x values/y values) can have the same (x values/y values)."

A tree grew from 6 feet to 12 feet in one year. What is the percent of change?
Answer:
100%
Step-by-step explanation:
It doubles in height, which makes it 100%
Answer:
100%
Step-by-step explanation:
The tree grew from 6 feet to 12 feet, which is a growth of 6 feet. 6 feet/6feet is 1, which in percent is 100%.
Now, you could say as the tree doubled in size, the change is 200%, however you must subtract the original height to gain the amount of change. So, 12-6 = 6, and 6/6 = 1, 1*100 = 100%.

When multiplying the 2 and the -12 it would be -24, not 24. Which if my mental math is correct, would make the answer 6
Edit:
Note that subtracting a negative is the same as adding the absolute value.
so:
-24-(-30)
changes to
-24+30
and it equals

5 apples and 6 bananas cost $9.55. 8 apples and 10 bananas cost $15.60. What is the cost of one apple?
Answer
$1.95
Step-by-step explanation:
15.60 divided by 8
2. AB – AD and BC - DC. Solve for x:
Answer:
From the diagram since AB = AD = BD, hence ABD is an equilateral triangle. (All angles = 60 degrees)
ADC is a straight line, hence BDC = 120 degrees and triangle BDC is an isosceles triangle.
Hence angle B = C and B+C = 180-120 = 60 degrees.
Hence, (x) angle C = A. 30 degrees

What is the value of the missing exponent?
(x^3)^6=x^?
Answer:
[tex]x^{18}[/tex]
Step-by-step explanation:
When one exponent is being raised by another exponent, you can multiply them. The base remains the same.
3 * 6 = 18
Help, 5 says write the equation you would use to find the measure of each angle
Answer:
x=18, 4x=72, x=90
Step by-step explanation:
180 degrees = 90 degrees + x+ 4x
180 degrees = 90 +5x
180-90=5x
90=5x
x=18 degrees
right angle: 90 degrees
4x= 72 degrees

Answer:
1)86
2)102
3)118
4)134
Step-by-step explanation:
1) so we know that the photographer started off with 86 photographs and has been uploading 16 each month since then
so in month 1 she would have 86
in month 2: 86+16=102
month 3: 102+16=118
month 4: 118+16=134
you could also use the expression
y=16x+70
how to get this equation: get slope(16) by subtracting p coords and m coord
substitute slope in slope intercept form
y=16x+b
insert in a coordinate pair(1,86)
86=16+b
b=70
hence y=16x+70

Function NotationStep-by-step explanation:
Step 1: Define
f(x) = 2x + 1
g(x) = 3x - 2
Step 2: Find g(1)
Substitute in x: g(1) = 3(1) - 2Multiply: g(1) = 3 - 2Subtract: g(1) = 1Step 3: Find f[g(1)]
Substitute in g(1): f[g(1)] = 2(1) + 1Multiply: f[g(1)] = 2 + 1Add: f[g(1)] = 3A system of linear equations is graphed below.
Which coordinate point represents the solution?
A.
(40, 0)
B.
(20, 20)
C.
(2, 2)
D.

Answer:
probably (20,20) if the equation is asking for were the points intersect. the intercept at (20,20)
Use the Rational Zeros Theorem to write a list of all potential rational zeros.
Answer:
1/5,2/5,4/5,1,2,4 B
Step-by-step explanation:
To my recollection the rational zeroes theorem is when you take all the factor of the Y intercept and list those and then take the factors from before and divide it by A
The first step would be to break down 4 into
1,2,4
Those are our first couple of answers, now it's time to divide it by 5
so we have 1/5, 2/5,4/5
Put it all together and get 1/5,2/5,4/5,1,2,4

Jada saw a music video that her favorite artist recently posted online. The equation v (t) = 320 ⋅ 4t represents the number of views v of the video, t days since Jada saw the video. What does v (2) equal? (only enter number)
Answer:
2,560
Step-by-step explanation:
The equation v(2) is equal to 2560.
What is a function?A function has an input and an output.
A function can be one-to-one or onto one.
It simply indicated the relationships between the input and the output.
Example:
f(x) = 2x + 1
f(1) = 2 + 1 = 3
f(2) = 2 x 2 + 1 = 4 + 1 = 5
The outputs of the functions are 3 and 5
The inputs of the function are 1 and 2.
We have,
v(t) = 320 x 4t ________(1)
v(t) represents the number of views v of the video, t days since Jada saw the video.
We see that,
v(t) is a function where t is the input and v(t) is the output.
Now,
Substitute t = 2 in (1)
v(t) = 320 x 4 x 2
= 320 x 8
= 2560
Thus,
The v(2) is equal to 2560.

10 of the students in an algebra class passed an algebra test. If these students are 50% of all the students in the class, how many students are in this algebra class?
Answer:
Are 20 students in the class
Step-by-step explanation:
[tex]x(0.5) = 10 \\ x = \frac{10}{0.5} \\ x = 20[/tex]
Answer:
50% is a pretty simple number and a percentage almost everyone knows.
Since this is usually common knowledge we can say that 10 is equal to said 50%. We need to find out how many people there are in this class, and we can set up two separate equations of addition. 50%+50%=x
10+10=k
50+50%=100% which is the max amount of kids that there cna be in this classroom, and that there are. This means that the number which is equal to 50% plus itself will also equal 100% of the students.
10+10=20
