2⁻³*(-7)⁻³ =(2*(-7))⁻³ =(-14)⁻³ =-14⁻³ =-1/14³Abigail orders a book and
two identical DVDs from
Amazon. The total bill is
$42.95. If the book
costs $7.65, then how
much does each DVD
cost?
Answer:
$17.65
Step-by-step explanation:
First you have to subtract $7.65 from the total cost, $42.95.
Now, you have $35.30. Since she bought 2 DVD's, you have to divid $35.30 by 2.
Your answer is now $17.65, meaning that each DVD cost $17.65.
the fee for charging an electric car at station A is $2 to start and $4 for each hour or fraction of an hour. Which point is NOT included in the graph of this step function?
A. (2.5, 14)
B. (2, 10)
C. (0,0)
D. (1,6)
The point (0, 0) is not lie on the graph of this step function.
What is an expression?
Mathematical expression is defined as the collection of the numbers variables and functions by using operations like addition, subtraction, multiplication, and division.
Given that;
The fee for charging an electric car at station A is $2 to start and $4 for each hour or fraction of an hour.
Now,
Since, The fee for charging an electric car at station A is $2 to start and $4 for each hour or fraction of an hour.
Hence, We can formulate the function as;
⇒ y = 4x + 2
Substitute (x, y) = (0, 0), we get;
⇒ y = 4x + 2
⇒ 0 = 4 × 0 + 2
⇒ 0 ≠ 2
Thus, The point (0, 0) is not lie on the graph of this step function.

Using the functions f(x) = (3 - x)/(x2 + 4) and g(x) = 3x, find the value of (f*g)(2).
9514 1404 393
Answer:
(f×g)(2) = 3/4
Step-by-step explanation:
For each of the functions, put 2 where x is and evaluate the expression.
f(2) = (3 -2)/(2² +4) = 1/8
g(2) = 3×2 = 6
Then the product is ...
(f×g)(2) = f(2)×g(2) = (1/8)×6 = 6/8
(f×g)(2) = 3/4
© Given that R= 9x + 8y
Find X when y 3 and R= 5
Give your answer as an improper fraction in its simplest form.
answer??
Answer:
-19/9
Step-by-step explanation:
First, you would plug in the numbers for y and r. Therefore, your equation should now be 5 = 9x + 24. Now you would put like terms on the same side. It now then look like -19 = 9x. You divide by 9 to get the x by itself. The answer should be x = -19/9.
Simplify the expression by combining like terms. -8y + 2 + 10y - 7
Please help
Answer:
2y - 5 (read below)
Step-by-step explanation:
-8y + 10y = 2y
2 + (-7) = -5
Your expression could/would be:
2y - 5.
Hope this helps!
Answer:
you can combine -8y and 10y since 8 is negative it would be =2y
an you can do 2+-7=-5
Which set of decimals is in order from least to greatest
1. 0.35, 0.3, 0.03
2. 0.3, 0.03, 0.35
3. 0.03, 0.3, 0.35
4. 0.03, 0.35, 0.3
Answer:2 1 4 then 3
Step-by-step explanation:
The option (3) 0.03, 0.3, 0.35 represents the order from least to greatest. Option (3) is correct.
What is number?A number is a mathematical entity that can be used to count, measure, or name things. For an example, 1, 2, 56, 0.3 etc. are the numbers.
We have decimal number:
0.35, 0.3, 0.03
Here, the smallest number is 0.03
And the greatest number is 0.35
So,
The order from least to greatest:
0.03 > 0.3 > 0.35
Thus, the option (3) 0.03, 0.3, 0.35 represents the order from least to greatest. Option (3) is correct.

I will mark you brainiest if you can answer this
Answer:
Step-by-step explanation:
a) PQ' / PQ = 12/8 = 3/2
Q'R' / QR = 15/10 = 3/2
PR' / PR = 9/6 = 3/2
b) this means that triangle PQR is congruent to triangle PQ'R'. Because if we divide each side we get 3/2 (SSS)
c) because QR and Q'R' are parallel and they have same angles.

Find the perimeter of the rectangle.
A rectangle with length 12 millimeters. The area of the rectangle is marked as 132 square millimeters.
Answer:
46 [tex]millimeters^{2}[/tex]
Step-by-step explanation:
What is given....
The length which is 12.
The area which is 132
We can use both of those to find the missing height
A = l * h
132 = 12 * h
132/12 = 12/12 * h
11 = h
Now that we found what "h" is, we can use that to find the perimeter....
Perimeter is when you add up all of the sides of a shape
L = 12
H = 11
There are 4 sides in a rectangle ( 2 sides for the height, and 2 sides for the lengths)
12 + 12 + 11 + 11
24 + 22
46
The perimeter of the rectangle is 46 [tex]millimeters^{2}[/tex]

What is the volume of the box?
Use unit cubes. Click the Unit Cube button below.
15 ft?
72 ft3
18 ft3
4 ft3
Answer: 72 ft^3
Step-by-step explanation:
When you fill the box with cubes you can plug in the numbers. The volume formula is length times width times height. With those cubes filled in the box the length is 3 the width is 6 and the height is 4. 3 times 6 times 4 is 72. I don’t know if it’s right but that’s what I think.
Answer: 18^3
Step-by-step explanation:
Once you find the volume (72) you have to multiply by 1/4 which makes it 18^3 ft - the guy above is wrong tbh
| 2x + 9 | = 15
Help pls
Answer:
x = 3 and x = -12
Step-by-step explanation:
To solve an absolute value equation, you create two equations, one where the right side is negated and one where the right side isn't:
| 2x + 9 | = 15 becomes:
2x + 9 = 15 and 2x + 9 = -15
2x = 6 and 2x = -24
x = 3 and x = -12
Why this works is that |-x| and |x| will both be equal to 0. Remember that absolute value is the distance a number is away from 0.

What is the slope of a lone represented by the equation2y-x=-4
Answer:
slope = [tex]\frac{1}{2}[/tex]
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y= intercept )
Given
2y - x = 4 ( add x to both sides )
2y = x + 4 ( divide all terms by 2 )
y = [tex]\frac{1}{2}[/tex] x + 2 ← in slope- intercept form
with slope m = [tex]\frac{1}{2}[/tex]
