Answers
Greetings.
The answer is y = -2.
Explanation:
The equation is defined to solve for y-term. Our y is currently our subject at this point and needs to be solved.
We move -3 to another side and leave y as the subject of equation. Moving to another side will change the sign/operator to opposite.

You start hiking at an elevation that is 80 meters below base camp.
You increase your elevation by 42 meters. What is the new elevation
with respect to base camp?
Answers
Answer:
You are now 38 m below base camp.
Step-by-step explanation:
Consider the provided information.
You start hiking at an elevation that is 80 meters below base camp.
Now your initial location is 80 m below base camp, that can be represents as: -80
Now you increase your elevation by 42.
So you go up by 42.
In other words, you get the equation -80+42 = -38.
Since a negative value is below the base camp, this means that you are now 38 m below base camp.

Step-by-step explanation:
If two lines are parallel, slope is equal
If perpendicular, product of slopes is -1
y = mx + c is the general equation of a line form
m represents slope
1. slope is -1 and 1, they are perpendicular
2. Slope is 5 in both cases, they are parallel
3. slope is equal; equation ii is same as i if rewritten
They are parallel

john swims 5/12 of a mile in 3/8 of an hour. What distance, in miles, does john swims in an hour?
A.) 1 5/9
B.)15/96
C.)5/20
D.)1 5/12
Answers
Answer:
1 1/9 miles
Step-by-step explanation:
If john swims 5/12 of a mile in 3/8 of an hour, then;
5/12 miles = 3/8 hours
TO get the number of miles he swims in an hour, we will say;
x miles = 1 hour
Equating both expressions
5/12 miles = 3/8 hours
x miles = 1 hour
Cross multiply
3/8 x = 5/12
3x/8 = 5/12
3x * 12 = 5 * 8
36x = 40
x = 40/36
x = 10/9
x = 1 1/9
The amount he swims in an hour is 1 1/9 miles

using both functions, determine which company is a better value for a 5 mile ride. show your work.
what are some real world limitations to the domain and range of both functions?
Answers
Answer:
See below
Step-by-step explanation:
Uber$5 pickup fee$0.25 per mileEquation
y = 0.25x + 5Cost of 5 miles:
y = 0.25(5) + 5 = $6.25KC yellow Cab Co.$1.75 pickup fee$0.75 per mileEquation
y = 0.75x + 1.75Cost of 5 miles:
y = 0.75(5) + 1.75 = $5.5Comparing the cost we see KC yellow Cab Co. is better value for a 5 mile ride.

Answers
Answer:

Step-by-step explanation:
enjoy enjoy hopefully it's right
Answer:
Slope = -3/2
y-intercept = 3
Step-by-step explanation:
Select any two points.
(x₁ , y₁) = (0, 3) & (x₂ , y₂) = (2 , 0)
Slope = [tex]\frac{y_{2}-y_{1}}{x_{2}-x_{1}}[/tex]
[tex]\frac{0-3}{2-0}\\\\=\frac{-3}{2}[/tex]
y - y₁ = m(x -x₁)
y - 3 = [tex]\frac{-3}{2}(x - 0)[/tex]
y - 3 = [tex]\frac{-3}{2}x[/tex]
[tex]y = \frac{-3}{2}x + 3[/tex]
Compare with y = mx + c
Slope = -3/2
y-intercept = 3

write the following as a fraction in simplest form and as a decimal:
143%

1/2%
1.9%
3/4%
Answers
Answer:
1.43
0.06
0.005
0.019
0.0075
Step-by-step explanation:
143% = 143/100 = 1 whole 43/100 = 1.43
6% = 6/100 = 3/50 = 0.06
1/2% = 0.5% = 0.5/100 = 1/200 = 0.005
1.9% = 1.9/100 = 19/1000 = 0.019
3/4% = 0.75/100 = 75/10000 = 3/400 = 0.0075
Jackie won tickets playing the bowling game at the local arcade. The first time, she won 60 tickets. The second time, she won a bonus, which was 4 times the number of tickets of the second prize. Altogether she won 200 tickets. How many tickets was the second prize?
Answers
28 is the number of tickets of the second prize
How to calculate how many tickets the second prize is?
A word problem is a mathematical exercise where significant background information on the problem is presented in ordinary language rather than in mathematical notation
Given that:
The first time wins = 60 tickets
The second time, she won a bonus, which was 4 times the number of tickets of the second prize
Altogether she won 200 tickets
Let N represent the number of tickets of the second prize
This can be written as:
60 + N + (4×N) = 200
60 + N + 4N = 200
60 + 5N = 200
5N = 200 -60
5N = 140
N = 140/5
N = 28
Therefore, the number of tickets of the second prize is 28
