C...to show this, interchange letters: x = (y+1)/(y-1)xy-x = y + 1xy - y) = x + 1y(x-1) = x+1y = (x+1)/(x-1) ⇐ this is f-1(x) and it's identical to f(x). Note: <span>the equal sign is missing in the definitions of the functions c. & d.</span>
Answer:
if they are similar then their sides are proportional and the following would be true:
40/30 = 48/36
reduce both sides:
4/3 = 4/3
so, yes, they are similar.
Step-by-step explanation:
1. The equations that I can think of are,
3 + 1 = 11 - 6
and
8 - 1 = 6 + 1
2. An example of equation that uses the variable x,
6x - 2x = 8
It may be required of you to perform certain steps in order to determine the value of x.
Answer:
60 square units; 40 units
Step-by-step explanation:
to find the missing side you use the pythagorean theorem
a^2 + b^2 = c^2
8^2 + b^2 = 17^2
64 + b^2 = 289
b^2 = 225
b = 15
area is l*h*1/2
15 * 8 * 1/2 = 60 square units
perimeter is adding them all
15 + 8 + 17 = 40 units
