The formula is y=mx+b
To get the slope or m, use this formula
(the second y minus the first y)/(the second x minus the first x)
Now set it up.
(10-7)/(2--1)
3/3=slope is 1.
y=1x+b
Insert one of the points for x and y.
i will do (-1,7)
7=1(-1)+b
7=-1+b
8=b
Insert this into the final equation:
y=1x+8
Try it out. If you're not sure, try both points. If it works, then you set it up correctly.
A) After any given year the amount of money would be: [(1000*.04)x]+1000
and x stands for the number of years.
B) The interest is 4%.
C) There would be $3,480.00 after 4 years.
Answer:
<h2>
y = -3x - 13</h2>
Step-by-step explanation:
The equation of the line in slope intercept form: y = mx + b
If the line: y = mx + b passes through point (x₁, y₁) that means the equation:
y₁ = mx₁ + b is true
b = -3
(-5, 2) ⇒ x₁ = -5, y₁ = 2
Therefore:
2 = -3(-5) + b
2 = 15 + b
b = -13
So, the equation of the line in slope intercept form that has a y-intercept of -3 and passes through (-5, 2):
y = -3x - 13
3 minutes
10*8*12=960 cubic inches
960/320inches per minute =3
For the first one, the graph shows a total of 12 representatives across all 5 categories, and of those, 2 are from the west this is the fraction 2/12, or the answer A) 1/6, meaning that 1 in 6 of the representatives are going to be from the western region.
For number 2, the answer is A) If you flip a coin 800 times, heads will come up about 400 times. This is because the law of large numbers says that as the number gets larger the ratio will get closer to 1:1. This means that since the coin only has 2 sides, it is about 50/50, meaning that of 800, 400 would be heads and 400 would be tails.
Hope this helps! :D
