Answer:
x-intercept = 10
y-intercept = -8
Step-by-step explanation:
To identify the y-intercept, we will need to format the equation in the form 
. We can start by subtracting 
from both sides of the equation:
Divide both sides of the equation by the coefficient of 
, which is 
:
The 
is representative of the y-intercept in .
Identify in the equation :
Therefore, our y-intercept is -8.
To solve for the x-intercept, replace the in the equation with a zero:
Add 
to both sides of the equation:
You can go ahead and divide 
by to get rid of the fraction:
Divide both sides of the equation by the coefficient of 
, which is 
:
Therefore, our x-intercept is 10.
Answer:
Step-by-step explanation:
Given
See attachment for cumulative frequency histogram
Solving (a): Swimmers between 200yd and 249yd
To do this, we simply read the data from the 0 mark
From the histogram, we have:
and
So:
This gives:
Solving (b): Swimmers between 150yd and 199yd
To do this, we simply read the data from the 0 mark
From the histogram, we have:
and
So:
This gives:
Solving (c): Total swimmers
To do this, we simply read the longest bar of the histogram
Hence:
Answer: At midnight It will be -10 degrees
Step-by-step explanation:
Circle F, diameter is 16 and the radius is half of the diameter
Hey there! I'm happy to help!
Slope intercept form is y=mx+b, where m is the slope and b is the y-intercept. We already have the slope, so our equation so far is y=3/2x+b. We just need to find the b for it to be complete.
To do this, we plug in a point on the line and solve for b. We have a point (-3,-4), so let's use it and solve.
-4=3/2(-3)+b
Undo parentheses.
-4=-9/2+b
Add 9/2 to both sides
b=1/2
Therefore, our equation is y=3/2x+1/2.
Have a wonderful day! :D
