to inverse a equation make all y's x and andy x's y
Thus the inverse is
x=4y-8
Evaluated to
4y=x+8
y= \frac{1}{4}x +2
X2<span> - 25 = x</span>2<span> - 5</span>2<span> = (x - 5)(x + 5)
</span>
X in this equation equals 140°
It would be b because a^2+b^2=c^2 so in this case 5^2+8^2=c^2
Answer:
You can do these "in your head" like this:
50 dimes would be $5.00
Each quarter adds 15 cents.
10.25 - 55.00 = $5.25 added
Step-by-step explanation:
525/15 = 35 quarters
--> 15 dimes
==========================
or,
d + q = 50
10d + 25q = 1025
etc
