Answer: y=-13/12x-7
Step-by-step explanation:
To find the slope-intercept form, we first need to find the slope. To find the slope, you use the formula 
. We use the two given points to find the slope.
Now that we have our slope, we can start filling out the slope-intercept form equation.
y=mx+b
y=-13/12x+b
Since we don't know the y-intercept, we can use one of the given points and solve for b.
6=(-13/12)(-12)+b [multiply (-13/12) and -12]
6=13+b [subtract both sides by 13]
b=-7
With the y-intercept, we can complete our equation.
y=-13/12x-7
Answer:
x=2
Step-by-step explanation:
-3 = -2x +1
+3 +2x = +2x +3
2x=4
divide them both by 2
x=2
Add the 8 to 24 and divide 32 by 2
Hello!
The formula for circumference is
and the formula for area of a circle is
. Armed with these formulas, we can begin to find the circumferences and areas of the circles.
20.
C =
C =
C =
C = 13(3.14)
C = 40.8
A =
A =
A =
A = 132.7
The circumference of the circle is 40.8 in and the area of the circle is 132.7 in².21.
[Since we are given the diameter for this problem, to find the circumference, we no longer need to multiply the radius by 2 as in
because the diameter is the radius × 2. For
we do need to divide the diameter by 2.]
C =
C = 49.3
A =
A =
A =
A = 193.5
The circumference of the circle is 49.3 in and the area of the circle is 193.5 in².
And that is all there is to it. I hope this helps you! (:
