Step-by-step explanation:

Step 1: Cross Multiply

$\frac{3}{y} = \frac{4}{5}$

$5(3) = 4(y)$

$15 = 4y$

Step 2: Divide both sides by 4

$15 / 4 = 4y / 4$

$3.75 = y$

Answer: $y = 3.75$

Which is an equivalent equation solved for y?

Nata [24]

X and y are the half length of the largest and smallest diameter of the ellipse.
Area of the Ellipse , a = πxy
To find: Equivalent Equation for y.

Consider,
a = πxy
πxy = a
(πx)y = a
transpose πx to RHS,

y = a ÷ ( πx )
Hope this helps!

Answer

x = 1

Explanation:

Given the following equation

$\begin{gathered} (2x+2)^{\frac{1}{2}}=\text{ -2} \\ \text{According to the law of indicies} \\ x^{\frac{1}{2}}\text{ = }\sqrt[]{x} \\ (2x+2)^{\frac{1}{2}}\text{ = }\sqrt[]{(2x\text{ + 2)}} \\ \text{Step 1: Take the square of both sides} \\ \sqrt[]{(2x\text{ + 2) }}\text{ = -2} \\ \sqrt[]{(2x+2)^2}=-2^2 \\ 2x\text{ + 2 = 4} \\ \text{Collect the like terms} \\ 2x\text{ = 4 - 2} \\ 2x\text{ = 2} \\ \text{Divide both sides by 2} \\ \frac{2x}{2}\text{ = }\frac{2}{2} \\ x\text{ = 1} \end{gathered}$

Therefore, x = 1
