Answer:
6x - 4
Step-by-step explanation:
Cross out the 3 in the denominator and the 9, which simplifies to 2 times 3x, which is 6x. For the second part, cross out 3 in the denominator and -6, which becomes 2 times (-2), which is -4.
Just type it into the graphing calculator, but reorder and solve for y first.
x + y = 9
y = 9 - x
y = x^2
In the graphing calculator,
Y1 = 9 - x,
Y2 = x^2
If you don't have a graphing calculator try desmos.
1. sqrt 52 = 7.211 rounds to 7
2. irrational number
3. sqrt 441 = 21....rational
4. 12^2 + 3^2 = h^2
144 + 9 = h^2
153 = h^2
sqrt 153 = h
12.4 = h <===
5. 6^2 + b^2 = 18^2
36 + b^2 = 324
b^2 = 324 - 36
b^2 = 288
b = sqrt 288
b = 16.97 rounds to 17 <==
6. 39^2 + 52^2 = c^2
1521 + 2704 = c^2
4225 = c^2
sqrt 4225 = c
65 = c
(39 + 52) - 65 = 91 - 65 = 26 miles shorter <==
7. 4^2 + b^2 = 16^2
16 + b^2 = 256
b^2 = 256 - 16
b^2 = 240
b = sqrt 240
b = 15.49 rounds to 15.5 <==
8. ?
I need the graph buddy boy
I count 5. There could be more. Sorry. Don't have scratch paper at the moment.
