Answer:
z>=2
Step-by-step explanation:
2z+2-4z+16<=2z+10
8<=4z
z>=2
Answer:
z[tex]\geq[/tex]2
Step-by-step explanation:
2( z + 1 ) - 4(z - 4) ≤ 2(z + 5)

300 pi
Solve the equation. Show all of your work. 1/59X + 60) = 2/3x- 2
Step-by-step explanation:
1/5x+60=2/3x-2
subtract 1/5x from 2/3x
when you do that you should get 0.46x repeating
then you add two to 60
you should get 62
62=0.46x
divide x
you get 134.7

long
The formula for the area of a square is A = s? where A stands for the area and
s is the length of one side.
What is the area of the pen?
ter ABUESTIONS
040 square feet
1600 square feet
80 square feet
400 square feet
Area =20^2 = 20 x 20 = 400 square feet
Answer: The answer is 400
Step-by-step explanation:
The answer is 400 because each side is 20feet and u have to multiply l x w so the answer is 400 because 20x20 is 400

Find the perimeter of the isosceles triangle in simplest radical form.
9514 1404 393
Answer:
6 +8√5
Step-by-step explanation:
The leg length can be reduced to simpler form:
3 +√45 = 3 +√(3²·5) = 3 +3√5
The perimeter is the sum of the side lengths, so is ...
(3 +3√5) +(3 +3√5) +(2√5) = 6 +8√5 . . . perimeter
A cheetah can run 97 km/hour. How fast can it run in 90 seconds? Round your answer
to the nearest hundredth.
The cheetah can run 2.42 km in 90 seconds
Calculating distanceFrom the question, we are to determine how fast the cheetah could run in 90 seconds
First, we will convert the speed to meter/seconds
The given speed = 97 km/hour
97 km/ hour = (97 × 1000 /3600) m/s
97 km/hours = 26.9444 m/s
Now, using the formula,
Distance = Speed × Time
From the given information,
Time = 90 seconds
∴ Distance = 26.9444 × 90
Distance = 2424.996 m
Distance = 2.424996 km
Distance ≅ 2.42 km
Hence, the cheetah can run 2.42 km in 90 seconds

Write a function to represent the set of ordered pairs.
{(2, 2), (3,7). (4, 14), (5,23)}
Answer:
Step-by-step explanation:
The set of ordered pairs {(1 , 7) , (−1 , 7) , (8 , −6) , (−3 , 2)} is a function
The set of ordered pairs {(4 , 7) , (−1 , 2) , (4 , −6) , (−3 , −2)} is not a
function
The set of ordered pairs {(3 , 7) , (−1 , 2) , (−4 , −2) , (−3 , −2)} is a function
The set of ordered pairs {(−3 , 7) , (1 , 2) , (4 ,−2) , (12,−4)} is a function
An ordered pair represents a relationship between two values
The first value is the input the second value is the output
1. A relation is a set of inputs and outputs
2. A function is a relation with one output for each input
3. All functions are relations
{(1 , 7) , (−1 , 7) , (8 , −6) , (−3 , 2)}
∵ Each x-coordinate in each ordered pair has only one y-coordinate
∴ The relation above is a function
The set of ordered pairs {(1 , 7) , (−1 , 7) , (8 , −6) , (−3 , 2)} is a function
{(4 , 7) , (−1 , 2) , (4 , −6) , (−3 , −2)}
∵ The x-coordinate 4 has two values of y (7 and -6)
∴ The relation above is not a function
The set of ordered pairs {(4 , 7) , (−1 , 2) , (4 , −6) , (−3 , −2)} is not a
function
{(3 , 7) , (−1 , 2) , (−4 , −2) , (−3 , −2)}
∵ Each x-coordinate in each ordered pair has only one y-coordinate
∴ The relation above is a function

The value of a car decreases by 20 percent per year. Mr. Sing purchases a $22,000 automobile. What is the value of the car at the end of the second year?
$14,080
$17,600
$19,800
$26,400
Answer:
$14,080
Step-by-step explanation:
You can use a formula for exponential decay, but since it is only 2 years, you can find 80% of the original value, and then 80% of the new value.
Original value: $22,000
Value after 1 year: 80% of $22,000 = 0.8 * $22,000 = $17,600
Value after 1 year: $17,600
Value after 2 years: 80% of $17,600 = 0.8 * $17,600 = $14,080
Answer: $14,080
Answer:
it is A , 14,080
