\sqrt{12}  -  \sqrt{4 \times 12}  =

\sqrt{4 \times 3}  -  \sqrt{4 \times 4 \times 3}  =

\sqrt{ {2}^{2} \times 3 }  -  \sqrt{ {4}^{2} \times 3 }  =

2 \sqrt{3}  -  4\sqrt{3}  =

6x + y = -2<br> y= -3x + 1<br><br> Graph the solution
Gala2k [10]
6x + y = -2
y = -3x + 1

Substitute the value of y in first equation, 
6x -3x + 1 = -2
3x = -2-1
x = -3/3
x = -1

Now, Substitute it in 2nd equation, 
y = -3(-1) + 1
y = 3+ 1 = 4

Coordinates would be: (-1,4) Mark that point and join with origin.

Hope this helps!

The best fit line is given by the equation y = 0.404x - 5.18, where y represents the height of the plant above ground level, and
IRISSAK [1]

Step-by-step explanation:

<u>The line of best fit given:</u>

  • y = 0.404x - 5.18

<u>It is given in the slope-intercept form:</u>

  • y = mx + b, where m- slope, b - y-intercept

The slope is this situation is m = 0.404 cm and it represents the average growth rate of the plant in one day.

It seems reasonable but without means of control it is difficult to trace the growth while still under the ground, during the first 13-14 days.

Katy's favorite rides at the amusement park are the roller coasters and water slide. The wait time for the roller coaster is 25
ioda

Answer:

She went on the slide 8 times and on the roller coaster 4 times

Step-by-step explanation:

We convert each statements to a mathematical equation.

Firstly, let's represent the number of times she went on the coaster with R and the number of times on the slide with S. We know quite well she went on 12 rides. Hence the summation of both number of times yield 12.

Mathematically, R + S = 12. ........(i)

Now we also know her total wait time was 3hours. Since an hour equals 60 minutes, her total wait time would equal 180 minutes.

To get a mathematical representation for the wait time, we multiply the number of roller coaster rides by 25 and that of the slides by 10.

Mathematically, 25R + 10S = 180 .......(ii)

Here we now have two equations that we can solve simultaneously.

From equation 1 we can say R = 12 - S. We can then substitute this into equation 2 to yield the following:

25(12 - s) + 10s = 180

300 - 25s + 10s = 180

300 - 25s + 10s = 180

300 - 15s = 180

15s = 300 - 180

15s = 120

S = 120/15

S = 8

S = 8 , and R = 12 - S = 12 - 8 = 4
