What is the slope of a line that is perpendicular to the line x = –3? –3 0 1/3 undefined

Mathematics
1 answer:
Elena L [17]3 years ago
8 0

Answer:

slope = 0

Step-by-step explanation:

The line with equation x = - 3 is a vertical line parallel to the y- axis

A perpendicular line is therefore a horizontal line parallel to the x- axis

The slope of the x- axis is zero, hence the slope of the horizontal line is

slope = 0

X - 4y = 12<br> X - 5y = 15<br> PLS HELP ME SOLVE USING ELIMINATION
balu736 [363]

Answer:

(0, -3)

General Formulas and Concepts:

<u>Pre-Algebra</u>

  • Order of Operations: BPEMDAS
  • Equality Properties

<u>Algebra I</u>

  • Solving systems of equations using substitution/elimination

Step-by-step explanation:

<u>Step 1: Define systems</u>

x - 4y = 12

x - 5y = 15

<u>Step 2: Solve for </u><em><u>y</u></em>

<em>Elimination</em>

  1. Subtract 2 equations:                    y = -3

<u>Step 3: Solve for </u><em><u>x</u></em>

  1. Define original equation:                    x - 4y = 12
  2. Substitute in <em>y</em>:                                     x - 4(-3) = 12
  3. Multiply:                                                x + 12 = 12
  4. Subtract 12 on both sides:                  x = 0

A contractor purchases 4 dozen pairs of padded work gloves for ​$56.16. She incorrectly calculates the unit price as ​$14.04 per
8090 [49]

Answer:

The correct unit price is $1.17 per pair of gloves. The error is she used number of dozens so, firstly convert it to number of pairs of gloves then divide.

Step-by-step explanation:

It is given 4 dozen pairs of gloves for $56.16.

So, unit price = Divide the price by number of pairs of gloves.

And 1 dozen =12

So 4 dozen =4*12=48 pairs of gloves

So, to find unit rate divide 56.16  by 48.

Unit price =\frac{56.16}{48}= $1.17

So, the error is she didn't convert the dozen to units.

That made mistake in finding unit price.

Can someone show me how to even start with 1 and 2? ​
diamong [38]

All you need to know is that

\displaystyle \lim_{x\to\infty}a^x=\begin{cases} \infty \text{ if } a>1\\1 \text{ if } a=1\\0 \text{ if } 0\leq a

So, the first function grows exponentially and the second decays exponentially. The rate of growth/decay are the bases of the exponentials, which means 1.08 and 0.205
