You would solve the function but you would replace the variable with the number in the parenthesis. Like if it was f(2)=3x+4 then you would do 3(2)+4 which is 10.

Find the dimensions of a rectangle whose width is 5 miles less than its length and whose area is 84
Answer: the length of the rectangle is 12 miles and the width is 12-5=7 miles.
Step-by-step explanation:
84 divided by 10.92 long division(with work)
Answer:
7.692
Step-by-step explanation:
Divide 84 by 10.92 to get 7.69230769231
Round 7.69230769231 to the nearest thousandth to get 7.692.
Answer: 7.69 rounded
Step-by-step explanation: The numbers go on further but I just rounded it to the hundredths. The full number if you want is 7.69230769231.
Now, Change the divisor 10.92 to a whole number by moving the decimal point 2 places to the right. Then move the decimal point in the dividend the same, 2 places to the right.
We then have the equations:
8400 ÷ 1092 = 7.69
and therefore:
84 ÷ 10.92 = 7.69
Both calculated to 2 decimal places.
0 0 0 7. 6 9
1 0. 9 2 |8 4. 0 0 0 0

1. 0 0 8 0
− .9 8 2 8
.0 2 5 2
Remember that it can keep going on for more decimal places, but this is to 2 decimal places so the answer to 2 decimal places is 7.69.
Hope this helps!

Janet wants to build a fence around her square garden.her garden has an area of 81 square feet.How much fencing will Janet need?
Area of garden = 81 ft²
Area of square = side²
[tex] \rm \implies side ^{2} = 81 \\ \\ \rm \implies side = \sqrt{81} \\ \\ \rm \implies side = \sqrt{ {9}^{2} } \\ \\ \rm \implies side = 9 \: ft[/tex]
Perimeter of square = 4 × Side
= 4 × 9
= 36 ft
[tex] \therefore [/tex] Fencing needed by Janet = 36 ft

Answer:
The first one
Step-by-step explanation:
Bcs when u have a closed circle is when is less or equal to, and an open circle means greater/less to. And you have a closed bcs is less or equal to. So u look in the answers, you can already take two answers out which are the 2 and the 3 bcs they are open circle. Then x ≥ 98.6, then x is bigger than the 98.6 so the arrow would go to the right. And the answer would be first one
(How to do that in an easier way, Look at this ≥, the pointy side is aiming in the right so the arrow will go always to the right, THIS ONLY WORKS WHEN THE LETTER IS IN THE LEFT {EX. y ≤ 19, the arrow will be pointing in the left.)

Answer:
A. Simon's unit rate is 2 more miles per hour than Eric's unit rate
Step-by-step explanation:
We are concerned with the number of miles each runs in 1 hour.
For Eric, that means x=1 in his equation, so his mileage is ...
y = 6×1 = 6 . . . . miles
__
For Simon, it means we want to find time = 1 hour on the horizontal axis at the bottom of the graph. Then we want to see where the graphed line crosses that vertical line. The point of crossing has horizontal line that goes over to 8 on the vertical distance axis. That is, Simon runs 8 miles in 1 hour.
__
Eric's unit rate (miles in 1 hour) is 6 miles per hour.
Simon's unit rate (miles in 1 hour) is 8 miles per hour.
Simon's unit rate is 2 more miles per hour than Eric's unit rate.
Answer:
A. Simon's unit rate is 2 more miles per hour than Eric's unit rate

What is the equation of the circle with center (-3,1) that passes through the point (-5, 3)?
A)
(x - 3)2 + (y + 1)2 = 8
B)
(x + 3)2 + (y – 1)2 = 8
0)
(x + 1)2 – (y - 3)2 = 8
D)
(x + 3)2 - () - 1)2 = 8
Answer:
Option B) (x + 3)^2 + (y – 1)^2 = 8 is the correct answer.
Step-by-step explanation:
The equation of a circle with center (h,k) and radius r is given by:
[tex](x-h)^2 + (y-k)^2 = r^2[/tex]
Given
Center = (h,k) = (-3,1)
=> h = -3
=> k = 1
The distance between the center of circle and the point through which the circle passes will be the radius.
The distance formula is given by:
[tex]r = \sqrt{(x_2-x_1)^2+(y_2-y_1)^2[/tex]
Given
[tex](x_1,y_1) = (-3,1)\\(x_2,y_2) = (-5,3)[/tex]
Putting the values in the formula
[tex]r = \sqrt{(-5+3)^2+(3-1)^2}\\r = \sqrt{(-2)^2+(2)^2}\\r = \sqrt{4+4}\\r = \sqrt{8}[/tex]
Putting the values of h,k and r in general form of equation
[tex]\{x-(-3)}^2\} +(y-1)^2 = (\sqrt{8})^2\\(x+3)^2+(y-1)^2 = 8[/tex]
Hence,
Option B) (x + 3)^2 + (y – 1)^2 = 8 is the correct answer.

Matt runs in the park every day at the average rate of c meters per minute.
b
If Matt runs triple his regular speed for 20 minutes, what distance would he cover?
Answer:
distance = 20c
Step-by-step explanation:
distance = speed x time
speed= c
time=20mins
distance = 20 x c
= 20c
∠3 is a supplement of ∠4, and m∠4 = 68°. Find m∠3.
Answer:
112°

Answer: 8
Step-by-step explanation:
8x0
The required amount of ounces of white paint added is 35.15 ounces.
Given that,
Liya has one 30-ounce jar of pink paint. The ratio of white paint in the jar is 3:7, Liya doesn't like the shade pink so she moves the paint into a 128-ounce container and adds more white and red paint to fill the container. If the new ratio of white paint to red is 3:5.
The ratio can be defined as the proportion of the fraction of one quantity towards others. e.g.- water in milk.
Here,
Ounces of white paint in a 30-ounce jar,
= 30 × 3 / 7 = 12.85,
Ounces of white paint in 128-ounce of the jar,
= 128 × 3 / 8 = 48
The number of ounces of white paint added = 48 - 12.85 = 35.15
Thus, the required amount of ounces of white paint added is 35.15 ounces.

. A person weighing 120 pounds has about 20 pints of blood in their body. Which equation below represents the relationship between pints of blood, b, to a person's weight, w?
Answer:
[tex]w = 6b[/tex]
Step-by-step explanation:
Given
[tex]b = blood[/tex]
[tex]w = weight[/tex]
[tex]b = 20; when\ w = 120[/tex]
Required
Determine the equation that binds both parameters
First, we need to determine the constant of proportionality using:
[tex]w = k * b[/tex]
Where k represents the constant.
Substitute 120 for w and 20 for b
[tex]120 = k * 20[/tex]
Divide both sides by 20
[tex]6 = k[/tex]
[tex]k = 6[/tex]
Using the same formula, substitute 6 for k
[tex]w = 6 * b[/tex]
[tex]w = 6b[/tex]
Hence:
The equation is represented as [tex]w = 6b[/tex]
