Explanation:
Relation I has each item in the domain map to exactly one item in the range. So any input leads to exactly one output. Therefore, we have a function here.
In contrast, relation II has the input x = 0 lead to multiple outputs (namely y = 8 and y = -1 at the same time). This indicates we do not have a function here.
Relation III is the same as as the previous one. This time the input x = -2 maps to both y = 1 and y = -7 at the same time. We don't have a function here either.
If you wanted, you can plot these points on the xy plane to see that relations II and III fail the vertical line test. You would need to plot each relation separately.
JEN PURCHASED THE ITEM SHOWN IN THE TABLE IN THE CITY IN THE SALES TAX RATE IS 7.15 IN ANOTHER CITY THE SALES TAX RATE IS 6.35 HOW MUCH MORE IS SHE SPENDING IF SHE PURCHASED THE ITEM==EN IN THE CITY WHERE SHE LIVES
Answer:
First, calculate the amount of sales tax by multiply the percent tax times the total cost:
0.07×600 =42
Next, add the amount of tax to the price of the computer:
600+42=642
$0.45792 more is she spending if she purchases the items in the city where she lives.
Given that, Jen purchased the items shown on the table. In the city she lives in, the sales tax rate is 7.15%. In another city, the sales tax rate is 6.35%.
We need to find out how much more is she spending if she purchases the items in the city where she lives.
What is the sales tax?A sales tax is a consumption tax imposed by the government on the sale of goods and services.
Now, the cost of the goods she purchased=11.99+35.50+6.75+3.00
=$57.24
The sales tax rate is 7.15%.
So, the sales tax=7.15% of 57.24
=$4.09266
The sales tax rate is 6.35%.
So, the sales tax=6.35% of 57.24
=$3.63474
Now, 4.09266-3.63474=$0.45792
Therefore, $0.45792 more is she spending if she purchases the items in the city where she lives.

60*(1/5) = 60/5 = 12
Candice scored 12 points.
Answer:
12
Step-by-step explanation:
60 multiplied by 1/5

choose the correct solution and graph for the inequality "-x/3<=6"
Answer:
Step-by-step explanation:
To solve this inequality, we have to find x (or make x the subject of the inequality:
since ⁻ˣ/₃ ≤ 6 [multiply both sides by 3]
- x ≤ 18 [multiply both sides by -1; this flips the inequality sign]
x ≥ - 18 [this is the solution]To graph the inequality, draw the line x = - 18 with a solid line, and then shade the region that is x > -18.
We use a solid line because the point x = -18 is included. However, hypothetically, if the inequality was x > -18 only, a broken line would be used to show that the line x = -18 is not included.
What is an equation of the line that passes through the points (4,4) and
(8, 1)?
Answer:
y = -3/4x + 7
Step-by-step explanation:
ok first u need to find the slope so use the slope equation for this (x2 - x1 over y2 - y1) so
1 - 4 = -3
8 - 4 4
so the m is -3/4
now you need to find the y intercept so pick one of the points (let's do (8, 1)) and plug that into the slope intercept form (y = mx+b)
so 1 = -3/4(8) + b
1 = -6 + b
+ 6 + 6
b = 7
so the equation is y = -3/4x + 7. hope this helps
Billy has 1 gallon of paint he’s going to pour it into a paint tray that measures 10 inches wide 14 inches long and 4 cm deep which of the following scenarios would happen
Answer:
Lets see if the gallon fill the paint tray or not.
For that purpose we need to find out the volume of the paint tray and compare it with the volume of the gallon.
Given:
Length = 14 inches
Width = 10 inches
Depth = 4 cm = 1.57 inches
Volume = length x width x depth
Volume = 14 x 10 x 1.57
= 220.47 inches cube
Volume of Gallon = 231 inches cube
Comparing the two volumes:
231 inches cube - 220.47 inches cube = 10.52 inches cube
Hence,
The paint will not fill the tray by 10.53 in3.

Alex is 22 years older than Lana. Four years ago Lana’s age was one-half of Alex’s current age. How old was Alex four years ago?
Answer:
33
Step-by-step explanation
22 divided by 2 is 11
it says four years ago so add 11 and 4 and that equals 15
she is 15 right now. then add 22 which is 37 and subtract 4 which your answer would be 33

A drinking glass is in the shape of a cylinder. The volume of the glass is 2211.68 cubic centimeters, and its diameter is 16 centimeters. Find the height of the glass.
Round the answer to the nearest centimeter. Include the units in your typed answer.
Answer:
11cm
Step-by-step explanation:
diameter = 16, r = 8 (16÷2)
π = 3.142
V=πr2h
2211.68 = π x 8^2 x h
2211.68 = 3.142 x 64 x h
2211.68 ÷ 64 ÷ 3.142 = h
h = 10.9986
= 11 cm (round off to nearest cm)
To check and confirm
V=πr2h
3.142 x 64 (8^2) x 10. 9986 = 2211.68

y ∝ 1 √ x If y = 7 when x = 36 find, y when x = 4
Help please
Answer:
Yo Rick Astley
Step-by-step explanation:
y ∝ 1 √ x
y = k (1 √ x)
y = 7 when x = 36
7 = k ( 1 / √36)
7 = k (1/6)
k= 7 × 6
k = 42
If x = 4 then,
y = 42 ( 1/√4)
y = 42 ( 1/2)
y= 21
If a, b, and c are solutions to the
equation 3x3 – 25x2 - 50x = 0 and
a < b < c, evaluate 10c – 6a.
Answer:
[tex]\displaystyle 10c - 6a = 110[/tex]
Step-by-step explanation:
We are given the equation:
[tex]\displaystyle 3x^3 - 25x^2 -50x = 0[/tex]
Where a, b, and c are solutions to the equation and where a < b < c, we want to determine the value of 10c - 6a.
To find the solutions of the equation, we can factor:
[tex]\displaystyle \begin{aligned} 3x^3 - 25x^2 -50x & = 0 \\ \\ x(3x^2 - 25x -50) & = 0 \\ \\ x(3x+5)(x-10) & = 0 \end{aligned}[/tex]
From the Zero Product Property:
[tex]\displaystyle x = 0 \text{ or } 3x + 5 = 0 \text{ or } x - 10 = 0[/tex]
Solve for each case:
[tex]\displaystyle x = 0 \text{ or } x = -\frac{5}{3} \text{ or } x = 10[/tex]
We can see that -5/3 < 0 < 10. Thus, a = -5/3, b = 0, and c = 10.
Therefore:
[tex]\displaystyle \begin{aligned} 10c - 6a & = 10(10) - 6\left(-\frac{5}{3}\right) \\ \\ &= 100 + 10 \\ \\ & = 110 \end{aligned}[/tex]

Step-by-step explanation:
find the unknown angle
Answer:
x = 35 degrees
y = 70 degrees
z = 75 degrees
Step-by-step explanation:
X will equal 35 degrees because that angle is vertical to the 35 degree angle, which means they are equal.
To find the measure of angle z, subtract the outside angle from 180:
180 - 105 = 75
To find the measure of angle y, add the two other known angles of the triangle and subtract that from 180:
35 + 75 = 110
180 - 110 = 70
Answer:
x = 35, y=75, z=70
Step-by-step explanation:
I dont know which angle you wanted exactly. However x is equal to 35 (I'm sorry, I forgot the name of the rule that makes that way, I assume it's in your notes if this is for a class). Z is equal to 75 because a straight line(the one on the bottom) is equal to 180 degrees. Since you have an angle on that line already (105), just subtract 180-105 to get 75.
Lastly, since we have x and z now, we can add them and subtract from 180(the degree in a triangle. So 35+75 = 110 and 180-110 = 70.

Answer:
Step-by-step explanation:
X=16x
z=116
16x+112=128
360-128=232
232 divide by 2=116
Answer:
x = 9
z = 68
Step-by-step explanation:
For x, the top and bottom angles have the same value. To get x, you need to set up this equation: 12x + 4 = 112. Subtract 4 from itself and from 112. Your equation will then be 12x = 108. Divide 108 by 12, and then your answer is 9. So the value of x is 9.
For z, it's supplementary with the top angle. This means that the two angles combined add up to 180. So your question is: 112 + z = 180. Subtract 112 from 180, and then your answer is 68. So the value of z is 68.
