Answer:

y = 3x + 4

Step-by-step explanation:

To find the slope, you need to subtract 4 from 13 and 0 from 3. So this will look like 9/3, which would be 3. To find the y-intercept, plug in one of the coordinates, so let's take (0, 4) since it's easier. If you plug in the 0 as the x and the 4 as the y in the equation, it should look like, 4 = 3(0) + b. 0 times 3 is 0, so that makes the b (y-intercept) 4.

\sqrt{27} - \sqrt{ 12} + \sqrt{48 }

Answer:

$5\sqrt{3}$

Step-by-step explanation:

I'm assuming you're asking for most simplified form?

Original Equation:

$\sqrt{27} - \sqrt{12} + \sqrt{48}$

Rewrite sqrt(27) using the exponent property: $\sqrt[n]{a} * \sqrt[n]{b} = \sqrt[n]{ab}$

$\sqrt{9} * \sqrt{3} -\sqrt{12} + \sqrt{48}$

Simplify sqrt(9)

$3\sqrt{3} -\sqrt{12} + \sqrt{48}$

Rewrite the radical sqrt(12)

$3\sqrt{3} -\sqrt{4}\sqrt{3} + \sqrt{48}$

Simplify sqrt(2)

$3 \sqrt{3} -2\sqrt{3} + \sqrt{48}$

Rewrite the radical sqrt(48)

$3\sqrt{3} -2\sqrt{3} + \sqrt{16}\sqrt{3}$

Simplify the sqrt(16)

$3\sqrt{3} -2\sqrt{3} + 4\sqrt{3}$

You can think of sqrt(3) as x, in which case you have 3x - 2x + 4x, so you just add the coefficients and leave the sqrt(3) alone.

Subtract 2 from 3

$1\sqrt{3} + 4\sqrt{3}$

Add 1 and 4

$5\sqrt{3}$

A hot air balloon festival, Mohammed’s balloon is at 40 feet and rises at a rate of 10 ft./min. dana’s balloon is at a height of

nekit [7.7K]

Answer:

5 minutes
90 ft

Step-by-step explanation:

After some number of minutes m, Mohammed's altitude will be ...

40 +10m

and Dana's altitude will be ...

165 -15m

The altitudes will be the same when ...

40 +10m = 165 -15m

25m = 125 . . . . . . . . . . . add 15m-40

m = 5 . . . . . . . . . . . . . . . divide by 25

The height of the two balloons after 5 minutes will be 40+10·5 = 90 ft.
