Select the correct locations on the graph.
Select the lines that represent functions.
All the lines given represent functions except the vertical line given which is attached below.
What is a Function?In a function, every x-values has only one possible y-value. Two x-values can have the same y-value but one x-value cannot have two different y-values. That is why a vertical line graph cannot in anyway represent a function.
An horizontal line graph is a constant function graph. Thus, all the lines represent functions except the vertical line that is attached below.

Research department eight employees budget of $11,500 department
Answer:
d. 80:8:3
Step-by-step explanation:
The question
For each $ 200 spent by the research department, sales department spends $ 20.For every $ 400 spent by the sales department the advertising department spends $ 150. The triple ratio of the money spent by the research department to the money spent by the sales department to the money spent by the advertising department fan be expressed as 2:1:5 b. 20:4:1 c. 40:8:3 d. 80:8:3
Research department : Sales Deptt: Advert Deptt
$ 200 : $ 20
$4000 : $ 400 : $150
( multiplying 400 with 10 to get the research department proportion)
400 : 40 :15 (dividng by 10)
80 : 8 : 3 ( dividing by 5)
Here we see that the ratio between the research department and the sales department is 10 :1 ( 200: 20)
Keeping the same ratio for the proportion given 400: 150 the $ 400 is multiplied with 10 to get the proportion of the research department.
Then we obtain 4000: 400: 150 which is reduced first by dividing with 10 and then 5 .
The original price of the shirt is $50 but you paid $30 for it on sale what was the percentage change in price
40% was the percentage change in price.
What is percentage?A value or ratio that may be stated as a fraction of 100 is referred to as a percentage in mathematics. If we need to compute a percentage of a number, we should divide it by its whole and then multiply it by 100. The proportion, therefore, refers to a component per hundred. Per 100 is what the term percent signifies. The letter "%" stands for it.
Given, The original price of the shirt is $50 but you paid $30 for it on sale
From the general formula of percentage change:
Percentage change = change in value / original value * 100
In our case,
Original value = 50
Change in values = 50 - 30
Change in values = 20
Percentage change = 20/50 * 100
Percentage change = 40
Therefore, the percentage change in price was 40%.

Eric rented a truck for one day the base fee was 16.95 for additional charge of .76 cents for each mile driven eric had to pay 152.23 when he returned the truck how many miles did he drive
Answer:
178 miles
Step-by-step explanation:
Let Eric has driven d miles.
As the rate of charge of driving the truck = 76 cents /mile
So, the charge of driving the truck for d miles = 76d cents= $0.76d
The base fee of the truck was $16.95.
Total money paid at the time of returning the truck = $152.23
So, 16.95+0.76d=152.23
0.76d= 152.23-16.95=135.28
d=135.28/0.76
d=178
Hence, he drives 178 miles.

(2A /h) - b1 = b2
Step-by-step explanation:
A = 1/2 h ( b1 + b2)
Multiply each side by 2
2A = 2*1/2 h ( b1 + b2)
2A = h ( b1 + b2)
Divide each side by h
2A/h= h/h ( b1 + b2)
2A/h= b1 + b2
Subtract b1 from each side
2A /h - b1 = b2

What was Marta’s mistake? Explain.
Answer:
Marta solved for y in the first equation and then substituted it back into that equation instead of the other one!
Step-by-step explanation:
edge 2020/2021
The mistake Marta did was substituting the value of a variable from equation 1 into same equation itself.
What is System of Equation?The system of equation is set of equations which have a common solution.
Marta was trying to solve the following equations:
10x+y = 22
2x+y =-2
For using the substitution method , the value of a variable is taken in terms of another variable from equation 1 and substituted in equation 2
y = 22 -10x will be substituted in equation 2
2x + (22-10x) = -2
2x +22 -10x = -2
-8x = -24
x = 3
y = -8
The system of equation has finite solution of x = 3, y =-8.

At an expected rate of return of 7% compounded semi-annually, what is the expected percentage growth of a portfolio after 4 years?
Answer:
The expected growth is 17.2%
Step-by-step explanation:
Let us have a present initial value of 500
we then proceed to get the value after 4 years
We use the compound interest formula to get the amount
That will be;
A = P( 1 + r/n)^nt
P = 500
r = 4% = 4/100 = 0.04
n is 2: semi annually means twice per year
t is 4
So
using the formula, we have that;
P = 500(1 + 0.04/2)^(2 * 4)
= 500(1.02)^8
= 586 approximately
So the percentage growth rate is as follows
(586-500)/500 * 100
= 86/500 * 100 = 17.2%

Answer:
About 145 miles.
Explanation:
Assume that the distance from the center of the earth to any point on the earth's surface is 4,000 miles.
Step-by-step explanation:
r = 4000
v = 13796/5280
(divide by 5280 to convert to miles)
Using Pythagorean's Theorem:
a^2 + b^2 = c^2
a^2 + 4000^2 = (4000 + 13796 /5280)^2
a^2 = (4000 + 13796 /5280)^2 − 4000^2
a = √(4000 + 13796 /5280)^2 − 4000^2 ≈ 144.6
