A rectangular doubles tennis court is (8x - 2) ft long and (4x - 4) ft wide. Which expression represents the perimeter of the tennis court?
A (12x - 6) ft
B. (12x + 6) ft
C (24x - 12) ft
D. (24x + 12) ft
If you can please show the steps
Answer:
C
Step-by-step explanation:
Remark
The easiest way to do this is to add the two givens together and then multiply by two. Why 2? Because the formula is P = 2(L + W)
Givens
L = 8x - 2
W = 4x - 4
Solution
P = 2*(8x - 2 + 4x - 4)
P = 2*(12x - 6)
P = 24x - 12

Answer:
1.The formula to convert Celsius to Fahrenheit is:
F = 1.8 C + 32
Multiply the Celsius temperature by 1.8.
Add 32 to this number.
Report the answer in degrees Fahrenheit.
Example: Convert 20°C to Fahrenheit.
F = 1.8 C + 32
F = 1.8 (20) + 32
1.8 x 20 = 36 so F = 36 + 32
36 + 32 = 68 so F = 68°F
20°C = 68°F

What is the solution to the system of equations?
(4, 0)
(−2, 3)
(0, 6)
(−4, 0)
Answer:
The answer is (-2,3)
Step-by-step explanation:
If you look at the coordinate plane, you'll notice that the x -values are negative and the y-values are positive. So, if you look at where the two lines meet, they meet at the point (-2,3).

Two trains on opposite tracks leave the same station at the same time. One train travels at an average speed of 80 kilometres per hour and the other travels at an average speed of 70 kilometres per hour. How long after they leave the station will they be 50 km apart?
Answer:
1/3 hr or 20 min.
Step-by-step explanation:
Call the trains A and B
Remember d = rt
Distance train A travels is 80t
Distance train B travels is 70t
Now, 80t + 70t = 50
150t = 50
t = 50/150 = 1/3 hr or 20 min.

what is value of x in the multi-step equation
22-9x=9x+10
Answer:
x= 2/3
Step-by-step explanation:
Step 1: Simplify both sides of the equation.
22−9x=9x+10
22+−9x=9x+10
−9x+22=9x+10
Step 2: Subtract 9x from both sides.
−9x+22−9x=9x+10−9x
−18x+22=10
Step 3: Subtract 22 from both sides.
−18x+22−22=10−22
−18x=−12
Step 4: Divide both sides by -18.
x=2/3

Answer:
a. The domain of the function is -3 < x ≤ 5
b. The range of the function is -3 ≤ y < 3
c. The y-intercept is the point (0, 0)
d. The values of 'x' at which f(x) ≥ 0 are;
x = -3, x = 1, x = 5
e. The intervals over which f(x) is decreasing are;
-3 < x ≤ - 1, and 1 ≤ x ≤ 3,
f. The local minimums are;
(-1, -1), and (3, -3)
Step-by-step explanation:
a. The domain of a function is the set of the possible independent variable values
Therefore, the domain of the function is -3 < x ≤ 5
b. The range of a function is the set of the possible values of the dependent variable
Therefore, the range of the function is -3 ≤ y < 3
c. The y-intercept is the point (0, 0)
d. The values of 'x' for which f(x) ≥ 0 are;
x = -3, x = 1, x = 5
The range of values of 'x' where f(x) ≥ 0 are;
-3 < x ≤ - 1.5, 0 ≤ x ≤ 1.5, 4.5 ≤ x ≤ 5
e. f(x) is decreasing over the following intervals;
-3 < x ≤ - 1, and 1 ≤ x ≤ 3,
f. The local minimums are the points that are lowest compared to other nearby points
The local minimums are;
(-1, -1), and (3, -3).

The expression 2 - 2 + 5x is equivalent to the expression 5x
True or False
Answer:
True!
Step-by-step explanation:
Put all the whole numbers together so 2+ (-2) cancels out
2-2+5x
positive 5x would be the only thing left so there you go!!!
Identify the points which of the following coordinate pairs make the equation x - 9y = 12 true?
Show your reasoning.
1. ( 12, 0 )
2. ( 0, 12 )
3. ( 3, -1 )
4. ( 0, - 4/3 )
Answer:
Step-by-step explanation:
Because in equation x-9y=12
If we put x=12 and y=0 then it satisfy equation. (12)-9(0)=12
So, (12,0) make equation
(3,-1) also make equation
(3)-9(-1)=12
(0,-4/3) also make equation
Because
0-9(-4/3)=12
Only (0,12) is not making
Beacuse
(0)-9(12) is not equal to 12

The school orchestra is creating a CD of their last concert. The total cost to make the CD is $300 plus $2.50 per CD. They are selling the CDs for $10 each. How many CDs will they need to sell to make a profit?
Answer:
They need to sell more than 40 CDs to make a profit.
Explanation:
They will make a profit when the sales are higher than the cost and with the information provided, you can write the following inequality:
10x>300+2.5x, where x is the number of CDs sold
Now, you can solve for x:
10x-2.5x>300
7.5x>300
x>300/7.5
x>40
According to this, the answer is that they need to sell more than 40 CDs to make a profit.

In a certain Algebra 2 class of 24 students, 6 of them play basketball and 7 of them play baseball. There are 13 students who play neither sport. What is the probability that a student chosen randomly from the class plays basketball or baseball?
Answer:
13/24 or 54%
Step-by-step explanation:
There are 24 students in total. Total will also be the denominator. Add 6 + 7 to find the amount that play the sports. Insert the number (13) as the numerator. Divide 13 by 24 if you need to find the percent!
Answer: 11/24
Step-by-step explanation:
2+5+4 =11
Expect the 13 person/students didn't play
Total people 24
24-13=11
11/24
