Evaluate functions from their graph
Answers
Answer:
f(1) = 1
Step-by-step explanation:
To evaluate a function, you see the y value it gives when you plug in the x value.
When you plug in 1 for the x value, the y value is also 1, so f(1) = 1
For the y-values in the given in the table, add x-values that will eliminate the set of ordered pairs as being a function. State the four c-values. X, Y 9,2,6,11
Answers
The x-values could be 1,3,1,3 because this would eliminate it fom being a function.
There are 8 members on a board of directors. If they must form a subcommittee of 3 members, how many different subcommittees are possible
Answers

written with the correct number of significant digits?
Answers
Answer:
Tanya's height at age of 9 is 53.75 inches
Step-by-step explanation:

3 36.8
4 40
5 41.25
6 45
7 48.0
8 51.5
Tanya's height at the age of 8 = 51.5
We are given that Tonya grew 2.25 more inches before her 9 year height was recorded.
So, Tanya's height at age of 9 = 51.5+2.25
Tanya's height at age of 9 =53.75 inches
Hence Tanya's height at age of 9 is 53.75 inches

There are 15 students on the debate team. Of these, 3 are boys. Give the ratio of boys to girls on the debate team in simplest form.
Answers
Answer:
1/4
Step-by-step explanation:
15 - 3 = 12
3 : 12
1 : 4
In its most basic form, the debate team's male-to-female ratio is 1/4.
What is ratio?The ratio can be defined as the number that can be used to represent one quantity as a percentage of another. Only when the two numbers in a ratio have the same unit can they be compared. Ratios are used to compare two objects.
given, There are 15 students on the debate team. Of these, 3 are boys.
Since there are 3 boys out of 15
Thus,
Number of girl = 15 - 3
Number of girls = 12
Ratios compare two numbers, usually by dividing them. If you are comparing one data point (A) to another data point (B), your formula would be A/B. This means you are dividing information A by information B.
thus,
The ratio of boys to girls = 3/12
the Ratio of boys to girls = 1/4
therefore, the ratio of boys to girls on the debate team in simplest form is 1/4.

Answer:
[tex]WX = 83[/tex]
[tex]WY = 119[/tex]
[tex]XY = 36[/tex]
Step-by-step explanation:
Given
[tex]WX = 3y + 11\\WY = 6y - 25\\XY = y + 12[/tex]
Required
Determine the values of WX, XY and XY
Since X is between W and Y, we have:
[tex]WY = WX + XY[/tex]
[tex]6y - 25 = 3y + 11 + y + 12[/tex]
Collect Like Terms
[tex]6y - 3y - y = 25 + 11 + 12[/tex]
[tex]2y = 48[/tex]
Solve for y
[tex]y = 48/2[/tex]
[tex]y = 24[/tex]
Substitute 24 for y in
[tex]WX = 3y + 11\\WY = 6y - 25\\XY = y + 12[/tex]
[tex]WX = 3 * 24 + 11[/tex]
[tex]WX = 83[/tex]
[tex]WY = 6 * 24 - 25[/tex]
[tex]WY = 119[/tex]
[tex]XY = 24 + 12[/tex]

Answers
Answer:
-4/19
Step-by-step explanation:
1. The first step to finding the reciprocal of -4 3/4 is to convert it into an improper fraction. To do that, multiply the -4 by the denominator, 4, and add the answer to the numerator, 3. The answer should come out to -19/4.
2. Now we have to find the reciprocal of -19/4 by flipping the denominator with the numerator, which is -4/19.
