Answer:
y = x/3 - 2 or f(x) = x/3 - 2
Step-by-step explanation:
f(x) = y
y = 3x + 6
To solve for inverse change y to x and x to y and solve for y.
x = 3y + 6 //Subtract 6 on both side
x - 6 = 3y //Divide 3 on both side
x/3 - 6/3 = y //Simply
y = x/3 - 2
In this image, the two angles (equations) form a right angle, which is 90°. You combine these equations: 4y-7+3y-1. When you combine like terms, you get 7y-8. You set this equal to 90°. 7y-8=90. Solve for y, and you get y=12.
D'ou know the area of a circle?
72:80
9:10
Divide 72 and 80 by 8 to simplify it and get the ratio
Each of the triangles are equal in base length, height, and area<span>. Remember the formula for the </span>area<span> of a triangle. The </span>area<span> of any triangle is 1/2 times the length of the base (which, in the </span>polygon<span>, is the length of a side) multiplied by the height (which is the same as the apothem in </span>regular polygon<span>).
