The graph of y = f(x) is the solid black graph below. Which function represents the dotted graph?
Answers
Answer:
y = -f(x - 5)
Step-by-step explanation:
the function of the dotted graph is f(x) shifted (or translated) 5 units to the right and then reflected across the x-axis.
shifting it to the right is happening by reducing every x value by 5 (so that we get for x the functional value of x-5).
and reflecting it across the x-axis simply means to flip the sign. everything that was originally above the x-axis is now with the same distance below the x-axis (and vice versa).
therefore, the new
y = -f(x - 5)

Which ordered pair is a solution of the equation -3+5y=2x+3y ?
Answers
Answer: x = y + −3/2
Step-by-step explanation:
Let's solve for x.
−3+5y=2x+3y
Step 1: Flip the equation.
2x+3y=5y−3
Step 2: Add -3y to both sides.
2x+3y+−3y=5y−3+−3y
2x=2y−3
Step 3: Divide both sides by 2.
2x/2 = 2y - 3/2

Kendra earns $70 per week mowing lawns. She saves 60% of the money she earns each week. How many weeks will it take Kendra to save enough money to buy a game system that costs $210?
Answers
Answer:
5 weeks
Step-by-step explanation:
Let's find how much money she saves a week by multiplying the decimal form of 60% and $70.
To get the decimal form of a percent you have to move the decimal to the left twice, like this: 60 ---> .60
Now that we have the decimal form of the percent we can multiply it by the 70 to find how much she saves a week:
(70)(.6) = 42
Therefore, Kendra saves $42 each week.
To find how many weeks it will take Kendra to buy the game system you divide $210 by the $42. Like this:
(210)/(42) = 5
All in all, it will take Kendra 5 weeks to save enough money to buy a game system that costs $210.
I hope this helps!!

Which equation has no solution?
O l-2x + 81 = 0
O [3x + 61 = 6
o 14x - 2) = -6
O 1-2 - x| = 9
Answers
Answer: |4x-2|=-6
Step-by-step explanation:
This has no solution
The equation that has no solution is | 4x - 2 | = -6.
What is an equation?Two algebraic expressions having the same value and symbol '=' in between are called an equation.
| -2x + 8 | = 0: This equation has only one solution, which is x = 4. When we take the absolute value of any number, the result is always non-negative (i.e., greater than or equal to zero).
Therefore, the absolute value of -2x + 8 can only be zero if -2x + 8 itself is zero. Solving for x, we get x = 4.
| 3x + 6 | = 6: This equation has two possible solutions, which are x = 0 and x = -4. When we take the absolute value of 3x + 6, the result can be either positive or negative, depending on the value of x.
Therefore, we need to solve two separate equations: 3x + 6 = 6 and 3x + 6 = -6. Solving for x in each case, we get x = 0 and x = -4.
| 4x - 2 | = -6: As I mentioned in my previous answer, this equation has no solutions.
An absolute value cannot be negative or equal to a negative number, so there is no value of x that would make the left-hand side of the equation equal to -6.
| -2 - x | = 9: This equation has two possible solutions, which are x = -11 and x = 7. When we take the absolute value of -2 - x, the result can be either positive or negative, depending on the value of x.
Therefore, we need to solve two separate equations: -2 - x = 9 and -2 - x = -9. Solving for x in each case, we get x = -11 and x = 7.

The amount of time it takes a water pump to empty a tank varles directly as the capacity of the tank. If it takes a water pump 2.5 hours to empty
a tank containing 60,000 gallons of water, how long does it take the same pump to empty a tank containing 108,000 gallons of water?
It will take {BLANK} hours to empty the second tank.
Answers
Answer: 4.5 hours
Step-by-step explanation:
First you put 60000 and change 2.5 hours into minutes then divide by that, inwhich you get 400. After getting 400 divide 108000 by 400 which equals 270, divide by 60 for hours.
It would take the same pump 4.5 hours to empty a tank containing 108,000 gallons of water.
What is an expression?In mathematics, an expression is a combination of numbers, variables, and mathematical operations such as addition, subtraction, multiplication, and division. An expression can also include mathematical functions, parentheses, and other symbols.
Let x be the amount of time (in hours) it takes the pump to empty a tank containing 108,000 gallons of water.
Using the direct variation formula, we can write:
time = k x capacity
Where k is the constant of variation.
We can use the given information to find k:
2.5 = k x 60000
k = 2.5 / 60000
k = 0.00004167
Now we can use this value of k to find x:
x = k x 108000
x = 4.5
Therefore, it would take the same pump 4.5 hours to empty a tank containing 108,000 gallons of water.

Answers
The employee will receive a percentage raise after 16 years is $69,168
How to calculate the employee salary after 16 years ?The first step is to calculate the percentage raise of the salary per year
= 2/100 × 52,400
= 0.02 × 52,400
= 1,048
The next step is to multiply 1,048 by the number of years
= 1048 × 16
= 16,768
The salary after 16 years can be calculated as follows
= 52,400 + 16,768
= 69,168
Hence the employee salary after 16 years is $69,168

Answers
Answer:

Step-by-step explanation:
To write a number in scientific notation, you need to reduce the number to one which is between 0 and 10.
In this case, 725 and 72.5 aren't possible as they are more than 10.
7.25 is the number we want. So simply count the number of decimal places you need to move in order to turn 7,250,000,000 into 7.25.

The length of Philip's stride when walking is 4 inches greater than the length of Anne's stride. If it takes Philip 5 steps and Anne 6 steps to walk the same distance, what is the length of Anne's stride?
Answers
Answer:
20
Step-by-step explanation:
Let :
Length of Anne's stride = x
Length of Phillips stride = x + 4
Number of steps taken to walk same distance :
Anne = 6 steps ; Philips = 5 steps
Distance moved = Length of stride * number of strides
Hence,
For same distance :
Anne's distance = Phillip's distance
x * 6 = (x + 4) * 5
6x = 5x + 20
6x - 5x = 20
x = 20
Length of Anne's stride = 20
