Explain why f(x-4) shifts to the right, while f(x+3) shifts to the left
Answer:
It is just because f(9x-4) is a subtraction so it goes to the right.
Then the f(x+3) is addition so it goes to left.
Step-by-step explanation:
It is like the opposite of their signs the adding is left, and the subtraction is right.
Adrian needs to be at school at 7:45 am. It takes him 15 minutes to walk to school, 512 hour to eat breakfast, 0.7 hour to get dressed, and 0.15 hour to shower. What time should he wake up.
Correct question:
Adrian needs to be at school at 7:45 am. It takes him 15 minutes to walk to school, 5/12 hour to eat breakfast, 0.7 hour to get dressed, and 0.15 hour to shower. What time should he wake up.
Answer:
Adrian should wake up by 6.14 am
Step-by-step explanation:
Given;
time to walk to school, = 15 mins
time to eat breakfast = 5/12 hour = 25 mins
time to get dressed = 0.7hour = 42 mins
time to shower = 0.15 hour = 9 mins
time Adrian needs to be in school = 7.45 am
Count from this time he needs to be at school backwards by subtracting the time he will spend before reaching school;
7.45 am - 15 mins = 7.30 am
7.30 am - 25 mins = 7.05 am
7.05 am - 42 mins = 6.23 am
6.23 am - 9 mins = 6.14 am
Therefore, Adrian should wake up by 6.14 am

-4 = 3 + 7(x - 1)
What does x equal
Answer:
x = 0
Step-by-step explanation:
Given
- 4 = 3 + 7(x - 1) ← distribute and simplify right side
- 4 = 3 + 7x - 7
- 4 = 7x - 4 ( add 4 to both sides )
0 = 7x , then
x = 0

Cup o' Coffee buys its coffee for $1.25 a cup. The coffee shop then sells each cup for $3.75. What is the percent markup for a cup of coffee?
Answer:
47%
Step-by-step explanation:
.375 × .125 = .046875
rounding up, 5 keeps the 7 as is, 7 is greater than 5, therefore the 8, becomes a 9, 9 is greater than 5, so the 6 becomes a 7, .047.
move the decimal three digits to the left and you get, 47%.
Percentage markup is the percent of the difference of the selling price to the buying price of a product. The percent markup for a cup of coffee is 200%.
The percentage markup has to be find out for the cup of coffee.
What is percentage markup?Percentage markup is the percent of the difference of the selling price to the buying price of a product. It can be given as,
[tex]M=\dfrac{\rm SP-C}{C} \times 100[/tex]
Here, [tex]SP[/tex] is the selling price and [tex]C[/tex] is the cost of the product.
Given information-
The Cup o Coffee buys its coffee for $1.25 a cup.
The Cup o Coffee sells its coffee for $1.25 a cup.
To find out the percentage markup for the cup of coffee, put the values in the above formula. Thus,
[tex]M=\dfrac{3.75-1.25}{1.25} \times 100\\M=\dfrac{2.5}{1.25} \times 100\\M=200[/tex]
Hence the percent markup for a cup of coffee is 200%.

The radius of a circle is 7 feet . What is the circle's area?
Answer:
The circle's area is 153.93804 feet^2
Step-by-step explanation:
The formula for the area of a circle is [tex]a = \pi r^{2}[/tex]
Using this formula, input the number 7 in for "r" and solve:
a = pi ( 7 )^2
a = pi ( 49 )
a = 153.93804 feet^2
The area of the circle is 153.93804 feet^2. Round the number to the specified decimal point.
it costs $12 for admission to the Fair, plus $0.50 for each ticket yo play games. if you have a total of $30 to spend, what is the greatest amount of tickets you can buy?
Answer:
36 tickets
Step-by-step explanation:
First you set up your equation, which would be 12 + 0.50x = 30. Next you subtract 12 on both sides to get 0.50x = 18. Divide both sides by 0.50 to get x = 36.

A barrel filled with oil is a cylinder with a diameter of 22 inches and a height of 35.5 inches. There are 231 cubic inches in a liquid gallon, how many gallons of oil does the barrel hold
Answer: The barrel holds about 58.44 gallons of oil .
Step-by-step explanation:
Given : For cylinder , diameter = 22 inches and height = 35.5 inches
radius = 11 inches [half of diameter]
Volume of cylinder [tex]=\pi r^2h[/tex], where r= radius and h = height.
Volume of cylinder [tex]=\dfrac{22}{7}\times(11)^2\times 35.5=13500.14\text{ cubic inches}[/tex]
Since, There are 231 cubic inches in a liquid gallon, so.
1 cubic inch = [tex]\dfrac{1}{231}[/tex] gallon.
13500.14 cubic inch = [tex]13500.14\times\dfrac{1}{231}\approx58.44\text{ gallons}[/tex]
Hence, The barrel holds about 58.44 gallons of oil .

The lenght of a rectangle is 3 inches more then its width. Its perimeter is 42 inches, find the dimensions of the rectangle
Answer:
The problem uses the perimeter formula. P = 2w + 2l where w is the width, and l is the length.
We know the length (l) is 3 inches longer than it's width (or l = w+3). Substitute w +3 into Perimeter equation.
P = 2w + 2(w+3). That simplifies to P = 4w + 6.
Since P + 42, we have 42 = 4w +6. With some simple algebra we find that w = 9 and l = 12.

sin θ = 4 cos θ
Answer:
θ=arctan(4) or 75.96°
Step-by-step explanation:
sinθ=4cosθ (given)
sinθ/cosθ = 4cosθ/cosθ (divide both sides by cosθ)
sinθ/cosθ = 4 (cancel cosθ)
tanθ=4 (sin/cos is equal to tan)
θ=arctan(4)(transposing tan will give you arctan)
θ=75.96 (calculation will give you this)

How many solutions does the following equation have?
4(y - 30) - 4y + 12
Choose 1 answer:
А
No solutions
Exactly one solution
Infinitely many solutions
Answer:
Infinite solutions
Step-by-step explanation:
After you distribute, you get -108. The equation doesn't have an equal sign, but I don't think that matters. For every possible value of y, you get the answer -108, so the answer is either infinite solutions, or no solutions, depending on what you are trying to get the equation to equal to.
If it's a typo, and the negative is supposed to be an equal sign, the answer is no solutions.

Answer:
The length of h is 3cm.
Step-by-step explanation:
You are looking for h. In order to find h you need the equation of area of a triangle, which is a=1/2bh. They give you base and they give you area. Plugging the numbers in, the equation is 7 7/8 cm^2= 1/2(5 1/4)(h). Now you solve by getting h by itself.
2(7 7/8 cm^2)= (1/2(5 1/4)(h))2
(15 3/4)/(5 1/4)= ((5 1/4)(h))/(5 1/4)
3=h
