Write an equation in point-slope form of the line that passes through the point (2,−8) and has a slope of 4.
Answer:
y = 4x - 16
Step-by-step explanation:
Plug in the slope and point into y = mx + b, and solve for b:
y = mx + b
-8 = 4(2) + b
-8 = 8 + b
-16 = b
Then, plug in b and the slope into y = mx + b
y = 4x - 16 is the equation in point slope form
9514 1404 393
Answer:
y +8 = 4(x -2)
Step-by-step explanation:
Point-slope form of the equation of a line is ...
y -k = m(x -h) . . . . . line of slope m through point (h, k)
Filling in the given point and slope, you have ...
y -(-8) = 4(x -2)
y +8 = 4(x -2)
What is the slope of the line?

Step-by-step explanation:
uber charges a $5 pickup fee and $0.25 per mile. define variables and write an equation to model this situation.
KC yellow Cab Co. charges $1.75 for pickup and $0.75 per mile. define variables and write an equation to model this situation.
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?
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.

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
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
In softball, Marissa hits the ball 40% of the time when she is up to bat. Based on this information, how many times will Marissa hit the ball if she goes to bat 30 times?
Answer:
Marissa hit the ball 12 times if she goes to bat 30 times.
Step-by-step explanation:
Given that:
Marissa hits the ball 40% of the time when she is up to bat.
Marissa gets to bat for 30 times.
Balls hit by Marissa = 40% of the times Marissa goes to bat
Balls hit by Marissa = [tex]\frac{40}{100}*30[/tex]
Balls hit by Marissa = 0.4 * 30
Balls hit by Marissa = 12
Hence,
Marissa hit the ball 12 times if she goes to bat 30 times.
write the following as a fraction in simplest form and as a decimal:
143%
6%
1/2%
1.9%
3/4%
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

Answer:
x = 8
Step-by-step explanation:
10 x 8 = 80 and the bottom would equal 80 as well so you would get 1 ^^
Answer:
x =25/2
10/8 = x/10
- Cross multiply
8x=100
- Divide both sides by 8
x=100/8
- Simplify
x=25/2

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?
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
