<h2>Answer::</h2>

An equation has a proportional relationship if it can be written in the form y=kx where k is the constant of proportionality.

a.y=0.5x−2a.y=0.5x−2 does not have a proportional relationship since it has the term −2 on the right side.

b.y=1,000xb.y=1,000x has a proportional relationship with a constant of proportionality of 1,000.

c.y=x+1c.y=x+1 does not have a proportional relationship since it has the term 1 on the right side.

What is the longest line segment that can be drawn in a right rectangular prism that is 14 cm long 11 cm wide and 7 cm tall

weqwewe [10]

Answer:

The longest segment is approximately 19.13cm

Step-by-step explanation:

Given

$l = 14cm$

$w = 11cm$

$h = 7cm$

Required

The length of the longest segment (d)

This is calculated using:

$d = \sqrt{l^2 +w^2 + h^2$

So, we have:

$d = \sqrt{14^2 +11^2 +7^2$

Using a calculator, the equation becomes

$d = \sqrt{366$

Take square roots

$d = 19.13cm$

Help with this math question please

lakkis [162]

The given inequality is:

$|12x-18| \leq 18$

This inequality can be simplified as:

$-18 \leq 12x-18 \leq 18 \\ \\ 
-18 + 18 \leq 12x-18+18 \leq 18+18 \\ \\ 
0 \leq 12x \leq 36 \\ \\ 
0 \leq x \leq 3$

So, the solution to the given inequality in Interval Notation is [0,3]

Answer:

Molly

Step-by-step explanation:

Brady did not properly create a square.

The square of a binomial is ...

(a -b)² = a² -2ab +b²

Where a²=x² and -2ab = -4x, you find b=2. The constant term in the square is 2²=4. Brady shows it as -4, which is incorrect.

Molly's work is correct.
