A situation could be for example if you wanted to buy a large amount of {something} and you had $135. To find out how many you would be able to buy, you would solve the equation.

15x = 135 \\ \frac{15x}{15} = \frac{135}{15} \\ x = 9

So 9 would be the amount of {something} that you could buy.

Y = 3(x-2)^2 + 5
Orlov [11]

The y-intercept coordinate is at the point (0, 17)

<h3>Properties of functions</h3>

Given the following function expressed as:

y = 3(x-2)^2 + 5

  • The vertex of the function (h, k) is (2, 5) while the axis of symmetry is at x = 2
  • Domain are the input values for which the function exist. According to the function, the domain and  range exists on all real values

The x-intercept is the point where y = 0

3(x-2)^2 + 5=0\\3(x-2)^2  = -5\\(x-2)^2 = -5/3\\x - 2 = 25/9\\x = 25/9 + 2\\x = \frac{43}{9}

Hence the x-intercept is (43/9, 0)

The y-intercept is the point where x = 0

y=3(x-2)^2 + 5\\y=3(-2)^2 + 5\\y=12+5\\y=17

The y-intercept coordinate is at the point (0, 17)

There were thirteen friends playing a video game online when six players quit.If each player left had eight lives how many lives
Lorico [155]
They had 56 lives in total

Explanation: if there were thirteen friends to begin with and six quit that would leave them with 7 friends. If those seven remaining friends each had 8 lives, you multiply those 7 friends by 8 lives which would get 56.

If all thirteen friends were still in the game then they would have 104 lives all together.
