Answer:
First answer.
Step-by-step explanation:
This is called the Arc length, here is the formula:
Arc length = (angle/360)*(2Pi*radius)
So,
(45/360)*(2*3.14*4)
= 3.14
SO Pi !!!!!
Point slope form: (y-2) = 4(x-6)
Slope-intercept form: y=4x-22
Slope: 0 | Y intercept 0, 33
Answer:
B. 5x - 4y = 12
Step-by-step explanation:
Let's convert this to slope-intercept form to interpret the equation easier.
5x - 4y = 12
Subtract 5x from both sides.
-4y = -5x + 12
Divide both sides by -4.
y = 5/4x - 3
Based on this, we know the slope is 5/4 and the y-intercept is (0, -3). When you count the rise over run in the picture and look at the y-intercept, they match.
Let Amanda's age = x.
Gregory's age = x + 5.
Since Gregory is 17 years old.
17 = x + 5
x = 17 - 5
x = 12
Amanda is 12 years old.
