A relation contains the points (−2, 0), (−1, −1), (0, 2), (1, 0), and (1, −2). (show work if you can)
A. The relation does not represent y as a function of x, because each value of x is associated with a single value of y.
B. The relation represents y as a function of x, because one value of y is associated with two values of x.
C. The relation does not represent y as a function of x, because one value of x is associated with two values of y
D. The relation represents y as a function of x, because each value of x is associated with a single value of y.
Answer:
C. The relation does not represent y as a function of x, because one value of x is associated with two values of y
Step-by-step explanation:
I chose choice c because in the relation we can see that the x-value 1 repeated but their y-values are different, one has 0 as its y-value and one has -2 as its y-value. In a function, this can't happen so it's not a function.
Hope this helps you
Find the angle measure.
The measure of angle XYZ is
Answer:
∠XYZ = 102Step-by-step explanation:
1st step is to solve x from ΔWXY
∠W + ∠X + ∠Y = 180
where ∠W = 5x + 2
∠X = 7x + 4
∠Y = 180 - (15x - 18)
= 198 - 15x
now plugin values into the equation:
5x + 2 + 7x + 4 + 198 - 15x = 180
combine similar terms:
5x + 7x - 15x = 180 - 2 - 4 - 198
simplify:
-3x = -24
x = -24 / -3
x = 8
2nd step is to substitute x = 8 into ∠XYZ
∠XYZ = 15x - 18
∠XYZ = 15(8) - 18
∠XYZ = 102

Andrea has $18 to spend. She spent $6.50, including tax, to buy a notebook. She needs to save $5.75, but she wants to buy a snack. If candy bars cost $1.15 per package including tax, what inequality would show the maximum number of packages that Andrea can buy? Solve your inequality by showing your work and steps. Please help
Answer: total cost of the stuff she buys ≤ 18 since she only has 18 dollars to buy stuff
Step-by-step explanation:
let's add up the cost of the stuff she buys:
- a flat cost of $6.50
- a savings of $5.75 (she's technically not spending money but we can count this as part of her expenses since it's taking away from the 18 dollars)
- some number (x) candy bars. if each candy bar costs $1.15 then the money she spends on candy bars is $1.15
with that being said:
6.50 + 5.75 + 1.15x ≤ 18
solve for x
since we are talking about whole # candy bars, if you get a decimal from this, round down to the nearest whole #
Answer:
Andrea can buy 5 candy bars.
Step-by-step explanation:
First to solve this we will subtract 6.50 from 18 because Andrea already spent that money. Then we must subtract 5.75 from 18 because Andrea can't spend that money. All the subtracting equals 5.75. After that we can divide the remaining money by 1.15 to see how many candy bars we can buy which equals 5. Finally the answer is that Andrea can buy 5 candy bars.

Banks provide a number of services including all of the following except __________.
A. Payday Lending
B. Safety Deposit Boxes
C. Checking Assets
D. Cashier's Checks
Answer:
A. Payday Lending
Explanation:
Payday Lending is common for small lending companies and not banks. They assist clients who have a minimal amount of salary to borrow a small amount of money with a high interest. The amount of money he can borrow will depend on the amount of salary he receives per month. The client will not be required to give any form of collateral for the borrowed money, thus, the client is said to be high-risk. However, he will have to return the money over a short period of time with an interest rate that is high. Though it is easy to get a loan with this kind of service, you have to make sure that you are employed.
Banks prefer to offer loans to people who have a steady income and a certain amount of salary.

When he arrived at school how many conks did Billy had left? Skateboards cost €36 each in my local store. The shopkeeper says if I buy one I can buy another for only 7/9 of the normal price. How much would a second skateboard cost?
Answer: 64 ; $28
Step-by-step explanation:
A. Billy collected 256 conks but lost ¾ of them on his way to school through a hole in his bag. When he arrived at school how many conks did Billy had left?
Number of conks collected by Billy = 256
Fraction lost = 3/4
Amount lost = 3/4 × 256 = 192
Number of conks Billy has left will be:
= 256 - 192
= 64
B. Skateboards cost €36 each in my local store. The shopkeeper says if I buy one I can buy another for only 7/9 of the normal price. How much would a second skateboard cost?
This will cost:
= 7/9 × $36
= 7 × $4

On a roadtrip, the distance driven can be represented by
the following equation
y = 152
where x is the number of gallons of gas.
What does the 15 represent?
15 represent the car travled 15 miles / gallons.
Distance is a scalar quantity that refers to "how much ground an object has covered" during its motion.
We have been given that -
y = 15 * x
Where y = the distance and
x = the number of gallons of gas to cover that distance.
A common unit of capacity in English-speaking countries, equal to four quarts, the U.S. standard gallon being equal to 231 cubic inches (3.7853 liters), and the British imperial gallon to 277.42 cubic inches (4.546 liters).
Consider the units:
y[miles] = 15[??] * x[gallons]
15[??] = y[miles] / x[gallons]
[??] = [miles] / [gallons]
So the units of the parameter 15 must be [miles / gallon] to convert the gallons to miles.
Therefore 15 represents the miles / gallon for the vehicle.

If -2x+4= 8, will x be positive or negative? Without solving the equation, explain how you know.
Answer:
x is negative
Step-by-step explanation:
I know x will be negative without solving the equation because we can see that both sides equal positive 8 and for -2x to be positive the x value must be negative. when two negative values are multiplied they change into positive. If the x value was Positive this equation would be false.
Hope this helps you
Answer:
Yes, x will be negative.
We are given:
-2x + 4 = 8
This means that "something", in this case -2x, added to 4, equals 8
The only thing that can add to 4 and equal 8 is 4.
So, that means -2x has to equal 4, which is a positive number.
Negative x negative = positive.
-2 is already a negative number, so x has to be a negative number.

Answer:
(a). 35 units ; (b). 44 units

(a). 7y - 14 = 2y + 21 ⇒ y = 7
EF = 7(7) - 14 = 35 units
(b). EJ = JG
15x + 7 = 12x + 10 ⇒ x = 1
