Set up the system of equations described in the question, and add the equations:
________________
Now that we have x=14, the other side length can be solved by substituting 14 into either equation to get y=4.
The side length of one square is 14. The side length of the other is 4.
Answer:
B)
Step-by-step explanation:
Given f(x) = ( 7 - 8x )²
let f(x) be y,
y = ( 7 - 8x )² .............to find inverse we have to make x the subject.
±√y = 7 - 8x
-8x = √y - 7
x = (±√y - 7 ) / -8
Then,
Inverse of ( 7 - 8x )² is and is a function.
I don’t know which one you need help with so I’ll answer #1. A triangle cannot have two right angles because the angles in a triangle have to add up to 180°. Since a right angle is 90°, two of those will make 180°. Since a triangle has three angles, that doesn’t leave anything for the third angle, and you can’t have a 0° angle. Also, you could have figured this out by trying to draw it, it’s impossible! This is because it would require a fourth line to complete the shape, which makes it a square!
The answer would be about 98 hamburgers.
This is because you would have to divide 393 by 2 to get 196.5.
Since the number of cheeseburgers is doubled divide 196.5 by 2 to get 98.25.
Add 98.25 to 196.5 and get 294.75.
Subtract.
