Let x = times in the pool
Let y = times in the basketball courts

42=3x+5y
x+y=12
Therefore y = 12-x
Subsitute for y
42 = 3x + 5(12-x)
42 = 3x + 60 -5x
Subtract 60
-18 = -2x
9 = x

The person used the pool 9 times.

Y=x-3 what is my answer
ale4655 [162]

Answer:

x = 3 or y = -3

Step-by-step explanation:

To find x, substitute y with a 0.

0=x-3. Minus the x on both sides and x will equal 3

To find y, substitute x with a 0.

y=0-3. 0-3 equals -3 which means that y will equal -3

Rationalize the denominator and simplify.
Irina18 [472]

Answer:

\frac{3 \sqrt{2}  - 2 \sqrt{3} }{3 \sqrt{2}  + 2  \sqrt{3}  }   \times  \frac{3 \sqrt{2}  - 2 \sqrt{3} }{3 \sqrt{2}  - 2 \sqrt{3} }  \\  \\  =   \frac{18 + 12 - 12 \sqrt{6} }{18 - 12}  \\  \\  =  \frac{30 - 12 \sqrt{6} }{6}  \\  \\  = 5 - 2 \sqrt{6}

A) Write an equation for the line of best fit.
JulijaS [17]

Answer:

Step-by-step explanation:

For this equation you want to start with signing the equation for the best line of fit. You’re going to take your year in and your rabbitsFrom the table and you’re going to find the slope in the Y intercept which would be your MX and you’re B. If you used as most you want to pull up a table in the graphing calculator and into your data there when you get there and the next box under your table you’re going to put y1~mx1+b There it will show you your slope and your intercept along with other things you will need to know for the equation when you get here sleeping when you said you’re going to round to the second decimal place and then you should get y=8.2x-16451.3 Which will be your best line of fit. Now when you’re trying to estimate the number rabbit at the farm In 2016 you want to put your year where X is so you’ll input your 2016 where x is and you should get 8.2(2016)-16451.3From there you solve it and you’re around to the second decimal space and there you have your just wanna sit and your estimate
