Let's solve your equation step-by-step.1/2y−21/4=−35/4Step 1: Simplify both sides of the equation.12y+−21/4=−35/4Step 2: Add 21/4 to both sides.1/2y+−21/4+21/4=−35/4+21/41/2y=−7/2Step 3: Multiply both sides by 2.2*(1/2y)=2*(−7/2)y=−7Answer:y=−7

Find x when y = 32, given that x varies inversely as y, and x = 132 when y = 4.

gizmo_the_mogwai [7]

Answer:

When y=32, x=16.5

Step-by-step explanation:

Find x when y = 32, given that x varies inversely as y, and x = 132 when y = 4.

We are given:

x varies inversely with y

We can write it as: $x\:\alpha \:\frac{1}{y}$

$x=\frac{k}{y}$

We have x = 132, when y=4

We can find value of k by using these values

$x=\frac{k}{y}\\132=\frac{k}{4}\\k=132*4\\k=528$

We need to find x when y=32

$x=\frac{k}{y}\\x=\frac{528}{32}\\x=16.5$

So, when y=32, x=16.5

Which is the range of possible side lengths of the missing side?

Harlamova29_29 [7]

Answer:

5 < x <21

Step-by-step explanation:

The side lengths of a triangle :

The sum of two side lengths selected at random must be bigger than the third side length and their difference must be smaller than the third side length

If we call the third side x than

x must be smaller than 13 + 8 and x must be bigger than 13 - 8 which means

5 < x <21
