Step-by-step explanation:
No, in order for a set of numbers to be a function, it has to pass the vertical line test. Draw a vertical line to see if it intersects the line more than once. Another way to think about it, is that one singular x value cannot give two different y values. That is impossible.
For example at x = 0, there are two y values that relate to that point. I'm going to estimate the y value for simplicity and the purpose of explanation.

4. Which of the following values of x is not in the domain of f (x) = log; (10-2x)?
Answers
Answer:
its choice 3) 5
Step-by-step explanation:
We want to see which of the given values of x is not in the domain of f(x) = log(10 - 2x).
The correct option is (3); x = 5.
The domain is defined as the possible inputs of a given function f(x), in this particular case, we have:
f(x) = log(10 - 2x).
Remember that the logarithmic function is only defined for positive arguments, so the values of x that are NOT in the domain of f(x), are these x values such that:
10 - 2x ≤ 0
Solving it for x we have:
10 ≤ 2x
10/2 ≤ x
5 ≤ x
So any value of x equal to or larger than 5 is not in the domain of the given functions, and of the shown options, the only one that is equal or larger than 5 is x = 5, the third option.
So the correct option is the option (3).

A farmhouse shelters 7 animals. Some are horses and some are ducks. Altogether there are 20 legs. How many of each animal are there?
Answers
Answer:
3 horses and 4 ducks
Step-by-step explanation:
let h be the no. of horses and d be the no. of ducks
h+d=7
d=7-h
Since horses have 4 legs and ducks have 2 legs,
4h+2d=20
4h+2(7-h)=20
4h+14-2h=20
2h=6
h=3

f(x) = -⁴/₃x + 6Step-by-step explanation:
f(0) = 6 means y-intercept b = 6
So we have:
f(x) = mx + 6 and f(3) = 2
So:
2 = m×3 + 6
3m + 6 = 2
3m = 2 - 6
3m = -4
m = -⁴/₃
Therefore the function:
f(x) = -⁴/₃x + 6What is a equation of the line that passes through points (-6,3) and (2,7)

Sandra wants to park her car so that she optimizes the distance she has to walk to the art museum and the library. That is, she wants to park so that her total distance directly to each building is the shortest. Find where she should park.
Answers
Answer:
95 feet on the street towards the libraary
and 95 feet on the street towards the art museam
Recheck :
Total distance = 50 + 60 + 80 = 190
Each distance = 190/2 = 95
She should park her car distance from library 80 feet and go to museum first.
What is Algebra?A branch of mathematics known as algebra deals with symbols and the mathematical operations performed on them.
Variables are the name given to these symbols because they lack set values.
In order to determine the values, these symbols are also subjected to various addition, subtraction, multiplication, and division arithmetic operations.
Given:
let the distance to the library be x.
so, total y = 2(60+ x) 80 - x + 50
y= 50 + x (go to library First)
Again , y = 2 (50+ 80 -x ) + x + 60
y= 320 -x ( go to museum first)
Then when x= 80
y = 240 < 250
So, she should park her car distance from library 80 feet and go to museum first.

find the measure of angle 8
Answers
Answer: 18
Step-by-step explanation:
First we need to solve for x to find the measure of the adjacent angle.
-6x+64 = 8x + 162
subtract 162 to leave x by itself
-6x- 98 = 8x
add 6x to both sides
-98 = 14x
now divide by 14
x = -7
Now solve one of the given equations to find the measure of the adjacent angle.
8(-7)+162
-56 + 162 = 106
Meaning the measure of angle 8 is 18
because they'll add up to 180(The measure of the line)
Answer:
measure of angle 8 is 16 6/7
Step-by-step explanation:
-6x+64=8x+62 because there is a transversal.
2=14x
x=2/14
so, now you have to find 8x+162. 163 1/7 degrees. (Plug in variables)
measure of the angle we just found + measure of angle 8 is 180 degrees.
(straight line definition) so 180-163 1/7= 16 6/7
measure of angle 8 is 16 6/7

If function f(x) = 2x2 – 3x + 4, then f(x + 3) is equal to f(x+3)= 2x^2 +9x +13.
Degree of polynomial is two so it will have only two solution
f(a)=0 if x=a

f(b)=0 if x=b
so put X=x+3
we will get
2[x+3]^2 - 3[x+3] + 4 = 2x^2 +9x +13
so if f(x+3)= 2x^2 +9x +13
