Answer: -1/2

You get y = 2x - 5, so the slope is 2. Perpendicular lines have opposite-reciprocal slopes, so the slope of the line we want to find is -1/2.

Express each ratio as a unit rate.round to the bearest tenth,if necessary. 2 note books for $0.60
FrozenT [24]

Option B

2 notebooks for $ 0.60 expressed as unit rate is $ 0.30 per notebook

<h3><u>Solution:</u></h3>

We have to express ratio as unit rate

Given that, 2 notebooks for $ 0.60

Number of notebooks = 2

Cost of 2 notebooks = $ 0.60

So we have to find cost of 1 notebook

\begin{array}{l}{\text { cost of } 1 \text { notebook }=\frac{\text { cost of } 2 \text { notebook }}{2}} \\\\ {\text { cost of } 1 \text { notebook }=\frac{0.60}{2}=0.30}\end{array}

So unit rate = cost of 1 notebook = $ 0.30

So 2 notebooks for $ 0.60 as unit rate is $ 0.30 per notebook

Solve x^5-4x^3 is less than or equal to 0
Aleks04 [339]
Solve for x over the real numbers:
x^3 (x^2 - 4) = 0

Split into two equations:
x^3 = 0 or x^2 - 4 = 0

Take cube roots of both sides:
x = 0 or x^2 - 4 = 0

Add 4 to both sides:
x = 0 or x^2 = 4

Take the square root of both sides:
Answer:  x = 0 or x = 2 or x = -2
