Is the relation a function? Why or why not?
Answer:
Step-by-step explanation:
set up the relation as a table of ordered pairs. Then, test to see if each element in the domain is matched with exactly one element in the range. If so, you have a function!
Answer:
No
Step-by-step explanation:
What makes a function a function is that it only has one input for every output. So in other words the x can't have two y values. But on a graph you can just do the vertical line test to see if the line intersects the vertical line more than once for any x value, it fails. So if we use the vertical line test we can see that for the x value of 2 is intersected by the line more than once, so this isn't a function.

If the ratio of blue eyed students to non-blue eyed students is 7 to 12, about how many students would have have blue eyes out of 50 students ? A.29 B.18 C.85 D.45
Answer:
18
Step-by-step explanation:
the ratio of blue eyed students to non-blue eyed students is 7 to 12,
Total ratio = 7+12=19
Total student= 50 students
Ratio of blue eyes student= 7/19 ×50
=18.4
Hence, there are approximately 18 students with blue eyes.

What is the measure of DCB?
Solve for x, angle A, and Angle B
A x+50 B x+80 c72
9514 1404 393
Answer:
∠A = 39°
∠B = 69°
Step-by-step explanation:
We assume these are angles in a triangle, so their sum is 180°.
A + B + C = 180
(x+50) +(x +80) +72 = 180
2x +202 = 180
2x = -22
x = -11
Then the angle measures are ...
A = -11 +50 = 39
B = -11 +80 = 69
Angles A and B are 39° and 69°, respectively.

Answer:
FG - it is midline. FG = 5.
Explanation:
A midline in a triangle is a line segment connecting the midpoints of two sides.
A midline is half the length of the side to which it is parallel.
[tex]\dfrac{CE}{FG} =2\\\\ \dfrac{9x-26}{7x-23} =2\\\\9x-26=2(7x-23)\\9x-26=14x-46\\14x-9x=46-26\\5x=20\\x=4[/tex]
CE = 9 · 4 - 26 = 10
FG = 10/2 = 5

Use the original price and the markdown to find the retail price.
Original price: $70; Markdown: 24%
Answer:
$53.20
Step-by-step explanation:
First, you need to find 24% of $70.
Change the percent to a decimal.
24% to .24.
Multiply that times 70.
.24 x 70 = 16.8
This will be the amount of money taken off the original price, so you will subtract it from the $70.
70 - 16.8 = 53.2
Therefore, the retail price is $53.20

What is the Unit Rate for the speed of a car that travels 500 miles in 3.25 hours
At a local fair, the admission fees are $1.50 for children, $3 for college students, and $5 for adults,
On Saturday, 1300 tickets were sold and brought in $3800,
The number of college student tickets sold were 100 less than the number of adults tickets sold,
How many children's tickets were sold?
Answer: Number of children = 280 , Number of adults = 460.
Number of students = 360
Step-by-step explanation:
Let x= Number of children, y = number of adults.
Number of students = y-100
Given: At a local fair, the admission fees are $1.50 for children, $3 for college students, and $5 for adults.
1.50 x + 3 (y-100) + 5 y =3800 (i)
x+y-100+y= 1300 (ii)
From (iii)
1.50x + 3y -300+5y = 3800
⇒ 1.50x + 8y = 4100 (iii)
From (ii)
x+2y= 1200 (*)
⇒ 4x + 8y = 4800 (iv) [multiply 4 on both sides]
Eliminate (iii) from (iv) , we get
2.5x = 700
⇒ x= 280 [ Divide both sides by 2.5]
Put x= 280 in (*), we get
280+ 2 y= 1200
⇒ 2 y= 920
⇒ y = 460
Hence, Number of children = 280 , Number of adults = 460.
Number of students = 460-100 = 360

Use the distributive to evaluate each expression
4(12 + 3)
Answer: 60
Step-by-step explanation:
You do 4*12 and 4*3, 4*12=48, 4*3=12, Next you do 48+12 and you get 60
Answer: 4(12 + 3) = 48 + 12 = 60
Step-by-step explanation: We will use the distributive property to evaluate the expression, 4(12 + 3)
Simply do this by multiplying the number outside of the parenthesis by each number inside of the parenthesis.
4(12 + 3)
4 x 12 = 48 and 4 x 3 = 12
(48 + 12)
Now, add both numbers inside the parenthesis.
(48 + 12 = 60) or 60.
suppose that z varies jointly as x and y, and z=15 when x=1 and y=3. What is the constant of proportionality
Answer:
find z given x = 26 and y = 37
z = 2*26*37 = 1924
Step-by-step explanation:
i think
solve for x please!!!
Answer:
26
Step-by-step explanation:
Because these are remote exterior angles, you set (5x-2) equal to (2x+76)
After you set them equal you solve for x
5x-2=2x+76
5x=2x+78
3x=78
x=26
