It depends on the type of function, however there are patterns that can be found
A general rule of thumb to consider is as follows
f(x) + d shifts a function up d units
f(x) - d shifts a function down d units
Ex. [tex]f(x) = x^{2} +3[/tex] shifts up 3 units, and [tex]f(x) = 2x - 4[/tex] shifts down four units
f(x+c) shifts a function left c units
f(x-c) shifts a function right c units
EX. [tex]f(x) = (x+2)^{2}[/tex] shifts left 2 units, and [tex]f(x) =(x-7)^{2}[/tex] shifts right 7 units
-f(x) is a reflection over the x-axis
EX. [tex]f(x) = x^{2}[/tex] opens up, while [tex]f(x) = -x^{2}[/tex] opens down
These guidelines can also be combined
EX. [tex]f(x) = -(x-4)^{2} + 3[/tex] opens down, is shifted right 4 units, and is shifted up 3 units from the parent function

Claire said 4/3 /5/2 is 10/3. She reasoned 4/3 *5 = 20/3 and 20/3 / 2= 10/3
Clare's answer and reasoning are incorrect because she performed the multiplication operation (4/3) × 5 = 20/3 before the division operation and the correct quotient is 8/15, not 10/3.
To perform the division operation (4/3) ÷ (5/2), we need to first divide the numerator by the denominator.
This gives us (4/3) ÷ (5/2) = 8/15.
Thus, Clare's reasoning is incorrect because she did not apply the order of operations when simplifying the expression.
Instead, she performed the multiplication operation (4/3) × 5 = 20/3 before the division operation (20/3) ÷ 2 = 10/3.
Therefore, the correct quotient is 8/15, not 10/3.

During bowling practice, Marley rolled 28 strikes out of 70 attempts. What percent of Marley's
attempts were strikes?
40 percent of Marley's attempts were strikes, when Marley rolled 28 strikes out of 70 attempts.
Define percentage.Rather than being expressed as a fraction, a percentage is a piece of a whole expressed as a number between 0 and 100. Nothing is zero percent; everything is 100 percent; half of something is 50 percent; and nothing is zero percent. You divide the part of the whole by the whole and multiply the result by 100 to get the percentage. A % is a number that indicates how many out of 100 it is, and it can also be expressed as a decimal or a fraction. Put the percentage value in the numerator and 100 in the denominator to convert a percentage to a fraction.
Given,
28 strikes rolled by Marley
Total attempts = 70
For percentage,
28/ 70 × 100%
0.4 × 100%
40%
40 percent of Marley's attempts were strikes, when Marley rolled 28 strikes out of 70 attempts.

The Royal Fruit Company produces two types of fruit drinks. The first type is 40% pure fruit juice, and the second type is 90%
pure fruit juice. The company is attempting to produce a fruit drink that contains 45% pure fruit juice. How many pints of each
of the two existing types of drink must be used to make 170 pints of a mixture that is 45% pure fruit juice?
Answer: 131.36363 pints of the first type of drink, and 38.63636 pints of the second type of drink.
Step-by-step explanation:
We can use the principle of linear equations. Let's say that the first type of drink is represented by x, and the second type is represented by y. We can then set up the following system of equations:
x + y = 170 (1)
0.4x + 0.9y = 0.45 * 170 (2)
We can solve for x and y using the methods of linear algebra. To do this, we can multiply equation (1) by 0.9, and equation (2) by 0.4, and then subtract the two equations to get the following equation:
0.9x - 0.4y = 0.45 * 170 - 0.4x - 0.9y
0.5x = 0.45 * 170 - 0.9y
x = (0.45 * 170 - 0.9y) / 0.5
We can substitute this expression for x into equation (1) and solve for y:
y = 170 - x
y = 170 - (0.45 * 170 - 0.9y) / 0.5
2.2y = 170 - 0.45 * 170
y = (170 - 0.45 * 170) / 2.2
y = 85 / 2.2
We can then substitute this value for y back into equation (1) to solve for x:
x = 170 - y
x = 170 - (85 / 2.2)
x = 170 - 38.63636
x = 131.36363
Therefore, the Royal Fruit Company needs to use 131.36363 pints of the first type of drink, and 38.63636 pints of the second type of drink, in order to produce 170 pints of a mixture that is 45% pure fruit juice.

Based on these results, express the probability that the next customer will pay with a
debit card or a credit card as a decimal to the nearest hundredth.
The probability that the next customer pays with a debit card or a credit card will be 0.28.
What is probability?Its fundamental concept is that someone will nearly surely occur. The proportion of positive events in comparison to the total of occurrences.
Then the probability is given as,
P = (Favorable event) / (Total event)
Jacob claims an independent venture selling bagels. He realizes that somewhat recently 108 clients paid cash, 24 clients utilized a charge debit card, and 18 clients utilized a credit card.
The total number of events is given as,
Total event = 108 + 24 + 18
Total event = 150
The probability that the next customer pays with a debit card or a credit card is written as,
P = (24 / 150) + (18 / 150)
P = 42 / 150
P = 0.28

A. 0.06x + 40
B. 0.08x + 20
C. 0.1x + 10
D. 0.12x
Answer:
b. 0.08x + 20
Step-by-step explanation:
its B because the price goes up $40 every 500 KW's so
40 divided by 500 = 0.08
The expression used to calculate Naomi's electricity cost after using x kilowatt hours is 0.08x+20. Therefore, option B is the correct answer.
What is an expression?An expression is a combination of terms that are combined by using mathematical operations such as subtraction, addition, multiplication, and division.
From the graph we have, (500, 60), (1000, 100), (1500, 140) and (2000, 180).
We know that, slope of a line is Slope=(y2-y1)/(x2-x1)
= (100-60)/500
= 40/500
= 0.08
Substitute m=0.08 and (x, y)=(500, 60) in y=mx+c, we get
60=0.08(500)+c
60=40+c
c=20
Substitute m=0.08 and c=20 in y=mx+c, we get
y=0.08x+20
The expression used to calculate Naomi's electricity cost after using x kilowatt hours is 0.08x+20. Therefore, option B is the correct answer.
