The answer is -0.13071895424837 becuase the 4.24 will come first because of pemdas and the negatives Catherine negative in the parentheses come out and the negative will still be there.

Answer:
y = -4x -21
Step-by-step explanation:
Use slope intercept form:
y = mx + b
use slope from original line: y = -4x - 1 so slope is -4
use the given point (-4,-5) for the x and y values and solve for b
-5 = -4(-4) + b
-5 = 16 + b
-5 - 16 = b
-21 = b
substitute b value in slope intercept form
y = -4x - 21
Answer:
If you’re asking what the simplified version is, it would be 2b + 6c
Step-by-step explanation:
First, let's get the area of the entire triangle since we'll need it later. The area of a triangle is A=1/2*b*h
We can find the height with the Pythagorean theorem by splitting the triangle in half.
3^2+b^2=6^2
9+b^2=36
b^2=27
b=√27
Then we can find the area:
A=1/2*6*√27
A=3√27 or =9√3 or 15.59
Now we can find the area of each region in the triangle other than the shaded region because they are all portions of a circle.
Each region has an angle of 60 because this is an equilateral triangle. Therefore the area of each region other than the shaded region will be 1/6 the area of a circle with a radius of 3 because a full circle is 360 degrees.
A=pi*r^2/6
A=pi*9/6
A=4.71
So three of these regions would have an area of 14.14
We do the area of the triangle minus the area of these regions to get the area of the shaded region
15.59-14.14 = 1.45
Hope this helps!
