Answer:
b
Step-by-step explanation:
The slope-intercept form of the equation of a line is
y = mx + b,
where
m = slope and b = y-intercept.
The point (0, 3) is the y-intercept, so b = 3.
The slope is -2, so m = -2.
y = mx + b
y = -2x + 3
1. find slope
x=tickets sold
y=money made
slope=(y2-y1)/(x2-x1)
take any point
(5,23.75) and (10,47.50)
input (note, (x,y))
(47.50-23.75)/(10-5)=23.75/5=4.75
slope=4.75
y=mx+b
m=slope
b=yintercept
y=4.75x+b
input
47.5=4.75(10)+b
47.5=47.5+b
b=0
equation is y=4.75x
if ticket sold is 24 then x=24
y=4.75(24)
y=114
answer is $114
2. points
(0,56.00) and (3,45.5)
slope=(y2-y1)/(x2-x1)
slope=(45.5-56.00)/(3-0)=-3.5
y=-3.5x
slope=-3.5
logic it yourself
equation is
y=-3.5x+0
y intercept is when x=0 so when the start of it was or when time=0
x intercept is when y=0 is when he has no money left
1.a. rate of change=4.75
b. $114
2. a.do this yourself, (desmos graphing calculator)
b. slope=-3.5 (duh, means money goes down with time)
c. equaiton is y=-3.5x+0, xint meanss when he has no money, y int means when time=0 or when it started
Answer:
12% decrease
Step-by-step explanation:
You need to answer this question: What percent of 500 is 440? If you get the answer in a percentage, it will be the percent decrease of this situation.
The answer would be 88%. Meaning 440 is 88% of 500.
This would also mean 500-440 is 100%-88%. 60 is 12%.
Since the difference between 500 and 440 is 12% the answer is above.

Answer:
x = ± 10
Step-by-step explanation:
8x² - 7 = 793 ( add 7 to both sides )
8x² = 800 ( divide both sides by 8 )
x² = 100 ( take square root of both sides )
x = ± = ± 10
