Write the equation of the line that passes through the points (4, -8) and (-8, 1).
Put your answer in fully reduced point-slope form, unless it is a vertical or horizontal
line.
Answer:
y = -3/4x -5
Step-by-step explanation:
(4, -8) and (-8, 1)
m = (y2-y1)/(x2-x1)
m= (1+8)/(-8-4)
m = (9)/(-12)
m = -3/4
y - y1 = m(x-x1)
y + 8 = -3/4(x -4)
y + 8 = -3/4x + 3
y = -3/4x -5
Answer:
y = -3/4x - 5
Step-by-step explanation:
Hope this helps!
Renae has been playing Tower of Hanoi and has noticed that the minimum number of moves it takes to defeat the game is related to the number of disks she must move. She has recorded her observations below. Write an equation that describes this pattern. Show your work.
Number of Disks in the Tower ║Minimum Number of Moves
1 ║1
2║ 3
3 ║7
4 ║15
5 ║31
Answer:
[tex]y = 2^x - 1[/tex]
Step-by-step explanation:
Let the number of disks be x and the minimum number of moves be y.
[tex]y = 2^x - 1[/tex]
When x = 1: y = 1
[tex]y = 1 = 2 - 1 = 2^1 - 1[/tex]
When x = 2: y = 3
[tex]y = 3 = 4 - 1 = 2^2 - 1[/tex]
When x = 3: y = 7
[tex]y = 7 = 8 - 1 = 2^3 - 1[/tex]
When x=4: y = 15
[tex]y = 15 = 16 - 1 = 2^4 - 1[/tex]
When x = 5: y = 31
[tex]y = 31 = 32 - 1 = 2^5 - 1[/tex]
Notice that for each derived expression of y, the exponent of 2 is being replaced by the value of x.
The general equation is: [tex]y = 2^x - 1[/tex]
8 + 3 + 2a = -1 + 3a + 4
Answer:

Step-by-step explanation:
8 + 3 + 1 - 4 = 3a - 2a
8 = a
a = 8

Step-by-step explanation:
A rental car company charges $55.98 per day to rent a car and $0.14 for every
mile driven. Joseph wants to rent a car, knowing that:
• He plans to drive 375 miles.
• He has at most $300 to spend.
What is the maximum number of days that Joseph can rent the car while
staying within his budget?
Answer:
4 days
Step-by-step explanation:
0.14 × 375= $52.50
$300-52.50=247.50
247.50 ÷55.98= 4.42122186495
round 4.42122186495 to the nearest whole that won't go over 300 and its 4 at $223.92 and the if you add your 52.50 thats $276.42

Answer:
The y-intercept is 2 and the slope is 1/2. So the equation is y = 1/2x + 2
Step-by-step explanation:
The y-intercept is where the line starts on the y-axis. For the slope to the next point on the line you have to move 2 units to the right and 1 unit up. When writing the slope as a fraction, you always put how far you move up or down above how far you move to the right or left.
