Answer:

An equation like 2x + 3 = 7 is a simple type called a linear equation in one ... There are other types of equations, however, that can have several solutions. ... to solve an equation algebraically and you end up with an obvious identity (like 3 = 3)

What is the other way to solve besides multiplying both sides by a common factor

BabaBlast [244]

Answer:

Here's one way

Step-by-step explanation:

13) multiply each term by 24

9x - 32x = 96

-23x = 96, divide both sides by -23

x = -4.17

It took malcom 6 minutes to walk 500m from the bus stop to the opera house. How fastwas he travelling

mylen [45]

$v=\frac{s}{t}\\\\s=500m=0.5km\\\\t=6min=\frac{6}{60}h=\frac{1}{10}h=0.1h\\\\v=\frac{0.5}{0.1}\ km/h=5\ km/h$

Assuming the probability of a single sample testing positive is 0.15, find the probability of a positive result for two samples

Grace [21]

Answer:

$P(Positive\ Mixture) = 0.2775$

The probability is not low

Step-by-step explanation:

Given

$P(Single\ Positive) = 0.15$

$n = 2$

Required

$P(Positive\ Mixture)$

First, we calculate the probability of single negative using the complement rule

$P(Single\ Negative) = 1 - P(Single\ Positive)$

$P(Single\ Negative) = 1 - 0.15$

$P(Single\ Negative) = 0.85$

$P(Positive\ Mixture)$ is calculated using:

$P(Positive\ Mixture) = 1 - P(All\ Negative)$ ---- i.e. complement rule

So, we have:

$P(Positive\ Mixture) = 1 - 0.85^2$

$P(Positive\ Mixture) = 1 - 0.7225$

$P(Positive\ Mixture) = 0.2775$

<em>Probabilities less than 0.05 are considered low.</em>

<em>So, we can consider that the probability is not low because 0.2775 > 0.05</em>

Write a real-world problem that can be represented by the given equation. Explain what your variable represents. 2X + 6 = 3X + 4

Nina [5.8K]

Answer:

Choose one of these equations: (20 points) 10x + 12y = 10,500 4x + 6y = 2,340 10x + 6y = 150 a. Write your own word problem that could match one of the equations above. Abby makes $150 a day at her new job as an assistant for a fashion designer in New York. She earns $10 an hour plus $6 for every dress she trailers. How many hours does she have to work and how many dresses does she have to tailor to earn $150? b. Rewrite the equation in slope-intercept form. y= -(5)/(3)x + 25 c. Graph the Equation
