Answer:
y = -x + 8
Remember that the slope-intercept form had formula y = mx + b where m is the slope and b is the y-intercept.
Area of sector = 1/2 * r^2 * x where r = radius and x = angle in radians
86 = 1/2 * r^2 * pi/4
r^2 = 2 * 86 * 4 / pi = 219
r = sqrt 219
= 14.80
1 2/3 + 1 5/6
We’ll start by converting the 2/3 to 6ths so we have a common denominator.
Look at the denominator first. 3 x 2 is 6, so we need to multiply the numerator by 2 as well. 2/3 = 4/6.
So we have 1 4/6 + 1 5/6 = 2 9/6
But you know they’ll want you to reduce that so it’s 3 3/6...or 3 1/2.
Let me know where you have questions.
