Which equation represents a line with a slope of -2/3 that passes through point (5, -2)?
serg [7]

Answer:

c) 2x + 3y = 4

Step-by-step explanation:

−2 = −⅔[5] + b

−3⅓

1⅓ = b

y = −⅔x + 1⅓

Then convert to Standard Form:

y = −⅔x + 1⅓

+⅔x + ⅔x

__________

⅔x + y = 1⅓ [We do not want fractions in our Standard Equation, so multiply by the denominator to get rid of it.]

3[⅔x + y = 1⅓]

2x + 3y = 4

* 1⅓ = 4⁄3

A florist arranges 4 flower arrangements in 92 minutes.
Black_prince [1.1K]

Answer:

\boxed {\boxed {\sf 9 \ arrangements }}

Step-by-step explanation:

Let's set up a proportion using the following setup:

\frac{arrangements}{minutes} =\frac{arrangements}{minutes}

We know that the florist can arrange 4 in 92 minutes.

\frac{4 \ arrangements}{92 \ minutes} = \frac{arrangements}{minutes}

We don't know how many the florist can arrange in 207 minutes, so we say x arrangements can be completed in 207 minutes.

\frac{4 \ arrangements}{92 \ minutes} = \frac{ x \ arrangements}{ 207 \ minutes}

\frac{4}{92} =\frac{x}{207}

Solve for x by isolating it on one side of the proportion.

x is being divided by 207. The inverse of division is multiplication. Multiply both sides of the proportion by 207.

207*\frac{4}{92}=\frac{x}{207}*207

207*\frac{4}{92}=x

207*0.0434782609=x

9=x

The florist can arrange <u>9 arrangements</u> in 207 minutes.

What do you think Thomas Edison meant by the word perspiration? How do those words apply to what you've learned about businesses
EastWind [94]

1. Thomas Edison used "perspiration" to refer to the physical and mental efforts needed to achieve a meaningful purpose in any human endeavor.

2. As it applies to businesses, it is not enough to develop a business idea or plan, as the business person must be prepared to execute and carry the business idea or plan to fruition.

<h3>What does Thomas Edison's reference mean?</h3>

According to Thomas Edison, the superior intellect or creativity we associate with great minds comes from inspiration (the idea) and perspiration (hard work).

Perspiration literarily refers to the sweat that emanates as someone works hard.

Without a strong working ethic, it will be impossible to achieve great results from only the proposition of great ideas or business plans.
