\bf \begin{cases}
x=t^2+2\implies x-2=t^2\implies \sqrt{x-2}=\boxed{t}\\\\
y=t^2-4\\
----------\\
y=\left( \boxed{\sqrt{x-2}} \right)^2-4\implies y=x-2-4\\\\
y=x-6
\end{cases}

just a plain vanilla substitution

There are 230 calories in 4 ounce of a type of ice cream. How many calories are in 6 ounces of paper ice cream
serious [3.7K]

Answer:

345 calories.

Step-by-step explanation:

We have been given that there are 230 calories in 4 ounce of a type of ice cream.

First of all let us find calories per ounce ice-cream by dividing 230 by 4.

\text{Number of calories per ounce ice-cream}=\frac{230}{4}

\text{Number of calories per ounce ice-cream}=57.5

Therefore, the ice-cream contains 57.5 calories per ounce of ice-cream.

Let us find amount of calories in 6 ounces of ice-cream by multiplying number of calories per ounce by 6.

\text{Amount of calories in 6 ounces of ice-cream}=57.5\times 6

\text{Amount of calories in 6 ounces of ice-cream}=345

Therefore, there are 345 calories in 6 ounces of ice cream.

What is the side of equilateral triangle is altitude is 10
kotegsom [21]

Answer:

11.55

Step-by-step explanation:

An equilateral triangle is one which all it sides are equal.

10cm altitude means the height is 10cm.

Using Pythagoras theorem,

x² = 10² + (x/2)²

Assume that the side of the triangle is xcm

x² - x²/4 = 100

3x²/4 = 100

x = √(400/3)

x = 11.55cm
