Answer:
Number one is only a function
Step-by-step explanation:
A function has all different x values, but if there are two of the same x values with different y values, that is not a function. It’s okay if there are two do the same x values- they just have to have the same y values.
Number one has all different x values
Number two has an x value with two different y values, therefore it is not a function
Number 3 has two of the same x values but with different y values, so it’s not a function
Number four is not a function because of the vertical line test. You pick a point on the line and draw a vertical line all the way through the line. If that point passes through any other points, that it is not a function. Number four doesn’t pass the vertical line test, so it’s not a function.

In 2021 the age of Anis is x years . She is born when her mother was 32 years old. Her mother's age is now 3 times her age . Find the age of her mother , in years , in 2021 .
Answers
Answer:
The age of Anis mother in year [tex]2021[/tex] is [tex]48[/tex] years.
Step-by-step explanation:
The given statement is that the mother was [tex]32[/tex] years old when Anis was born, which means that Anis was zero year old.
After [tex]x[/tex] years, Anis is [tex]x[/tex] years old, in year [tex]2021[/tex], so her mother will also grow by [tex]x[/tex] years, so her mother's age will become [tex](32+x)[/tex] year.
But Anis mother's age is now [tex]3[/tex] times her age when she is [tex]x[/tex] years old, so her mother's age is [tex]3x[/tex] years, in year [tex]2021[/tex].
But her mother's age is also [tex](32+x)[/tex] years, in year [tex]2021[/tex].
So, the equation will become,
[tex]\begin{aligned}3x&=32+x\\3x-x&=32\\2x&=32\\x&=16\end{aligned}[/tex]
Her mother's age in year 2021 is,
[tex]\begin{aligned}3x&=3(16)\\&=48\:\rm{yrs}\end{aligned}[/tex]

Step-by-step explanation:
We can use the distance formula
11. d =sqrt( (y2-y1)^2 + (x2-x1) ^2)
= sqrt( (-3 --5)^2+(-6 - -1)^2)
= sqrt( (-3+5)^2 + (-6+1)^2)
= sqrt( 2^2 + (-5)^2)
= sqrt (4+25)
= sqrt(29)
12. Using the points ( 1,3) and (4,-1)
d =sqrt( (y2-y1)^2 + (x2-x1) ^2)
= sqrt( (-1-3)^2+(4-1)^2)
= sqrt( (-4)^2+(3)^2)
= sqrt(16+9)
=sqrt(25)

Answer:
17.5 mi/gal
Step-by-step explanation:
You can think of "per" as meaning "divided by." Then "miles per gallon" means "miles divided by gallons:"
(166.25 mi)/(9.5 gal) = 17.5 mi/gal
John's car gets 17.5 miles per gallon.
Callie wants to build a fence halfway between her house and her neighbor's house. How far away from Callie's house should the fence be built?
Answers
The distance of the fence from Callie's house is [tex]\frac{y}{2}[/tex]
Let the total distance between Callie and her neighbor's house = y
The distance from Callie + distance from her neighbor's house = y
The distance from Callie = half of the total distance
In mathematical equation, the distance of the fence from Callie's house is calculated as:
[tex]distance = \frac{y}{2} = \frac{total\ distance \ between \ Callie \ and \ her \ neighbor }{2}[/tex]
Thus, the distance of the fence from Callie's house is [tex]\frac{y}{2}[/tex]

Step-by-step explanation:
In order to find this, we simply need to select an x and it will help us find y. Our x for this case will be one. Now we put that into the equation and solve for the y value.
y=4x+9
y=4(1)+9
y=4+9
y=13
This gives us the ordered pair of (1,13)
