|Absolute Value| - makes any number positiveStep-by-step explanation:
Step 1: Define
|18 - 7| = |18| + |-7|
Step 2: Check
Subtract: |11| = |18| + |-7|Evaluate: 11 = 18 + 7Add: 11 ≠ 25Here we see that 11 does not equal 25.
∴ The statement is false.

The revenue earned from a sporting event can be determined by the ticket price, $125 each.
Answer:
all whole numbers
all whole-number multiples of 125
Step-by-step explanation:
The domain and the range of a function is the set of input and output values of the function.
The domain is the set of all whole numbersThe range is the set of all whole numbersLet the number of tickets be x, and the revenue be y.
So, the revenue function will be:
[tex]\mathbf{y = 125x}[/tex]
The number of tickets cannot be less than 0.
So, the domain of the revenue function is:
[tex]\mathbf{Domain = [0,\infty)}[/tex]
The above means that, the domain is the set of all whole numbers
Similarly, the revenue cannot be less than 0.
So, the range of the revenue function is:
[tex]\mathbf{Range = [0,\infty)}[/tex]
The above means that, the range is also the set of all whole numbers (in multiples of 125)

A) 64
B) 128
C) 8
D) 4
Answer:
the anser is 64 cups
Step-by-step explanation:
half gallon is 8 cups and she bought 8 of them so multiply 8 and 8 or 8^2 and you get 64
pls mark brainliest
Answer:
A. 64 cups
Step-by-step explanation:
There are 16 cups per gallon, so a half gallon would be 8 cups. If she bought 8 bottles that means you must take the 8 bottles times the 8 cups per bottle or just 8*8=64. Answer A. is 64 cups.

Quadratic – vertical compression by a factor of 1/3, vertical shift up 5 units
Answer:
Step-by-step explanation:
I used a site it won't let me mention... for this graph
This is if "vertical compression by a factor of 1/3, vertical shift up 5 units" translates to...
[tex]f(x)=\frac{1}{3} (x^2+5)[/tex]
The equation that has vertical compression by a factor of 1/3, vertical shift up 5 units will be y = (1/3)x² + 5.
What is the parabola?It's the locus of a moving point that keeps the same distance between a stationary point and a specified line. The focus is a non-movable point, while the directrix is a non-movable line.
The equation of a quadratic function, of vertex (h, k), is given by:
y = a(x – h)² + k
where a is the leading coefficient.
The vertical compression by a factor of 1/3, vertical shift up 5 units.
a = 3
(h, k) = (0, 5)
Then the equation will be
y = 1/3(x – 0)² + 5
y = (1/3)x² + 5

A yardstick casts a shadow of 24 in. At the same time a telephone pole casts a shadow of 20 ft 8 in. What is the height of the telephone pole, to the nearest inch? (1 yd = 36 in., and 1 ft = 12 in.)
Answer:
372 inches
Step-by-step explanation:
(1 yd = 36 in., and 1 ft = 12 in.)
1 yard stick = 24 in
This means , height of 36 inches casts a shadow of 24 Inches
At the same time a telephone pole casts a shadow of 20 ft 8 in
1 ft = 12 in
Hence,
Convey 20ft to inches
1 ft = 12 in
20 ft = 20 × 12 inches
= 240 inches
Total shadow of the telephone pole = 240in + 8 in = 248 = 248 inches
Hence,
Height/Length of shadow = Height/Length of shadow
36/24= x /248
Cross Multiply
24 × x = 36× 248
x = 36 × 248/24
x = 372 inches
The height of the telephone pole, to the nearest inch is 372 inches

The set of ordered pairs represents a function because every input has only one corresponding output.
what is the answer for x?
Answer:
x=5
Step-by-step explanation:
I first subtracted 88 from 180 because we know that 180 is the total degree of the three angles in a trangle. I got 92, then divided that by 2 since there are two angles that are unknown. I got 46, which I can then use to form the equation (9x+1)=46. I subtracted 1 from both sides to get rid of the 1 (since we're finding what x equals to), I then got 9x=45. After that, I divided 9 from both sides and got the answer x=5.

Answer:
a. y= -1221x+19820
b. For every year the car value decreases $1,221.
c. $11,273
Step-by-step explanation:
a. (y2-y1)/ (x2-x1)
(16157-17378)/(3-2)= -1221
For the y-intercept you would just add 1221 twice to the value of the 2 year old car, get the value of 0 years.
c. -1221(7) +19820 =$11,273
