Write the point-slope form of the equation of the line that passes through the point (-1, 5) and has a slope of -1. Include your
ivolga24 [154]

Answer:

y = -x + 4

Step-by-step explanation:

The point-slope formula for a straight line is

y – y₁ = m(x – x₁)

x₁ = -1; y₁ = 5; m = -1     Substitute the values

  y – 5 = -1(x + 1)          Remove parentheses

  y – 5 = -x - 1              Add 5 to each side

       y = -x + 4

The graph is a straight line with a y-intercept at y = +4 and a slope = -10/10

= -1.

Simplify: 0.9(2b-1)-0.5b+1
Nutka1998 [239]

Answer:

Step-by-step explanation:

0.9*2b = 1.8b

0.9*-1 = -0.9

So far we have 1.8b-0.9. It can't be simplified further.

Then, we add the 2nd part, -0.5b+1.

We have:

1.8b-0.9-0.5b+1. Next we combine like terms.

1.8b-0.5b = 1.3b.

-0.9+1 = 0.1

Then we put it together.

1.3b+0.1 is our answer.

Hope this helped! Have a nice day :D

Aleonysh [2.5K]

Answer:

<em>It takes them 1.875 hours.</em>

<em></em>

<em>Step-by-step explanation:</em>

<em></em>

<em>Here, the job is cleaning the house.</em>

<em></em>

<em>Mom does 1 job in 3 hours.</em>

<em></em>

<em>In 1 hour, mom does 1/3 of the job.</em>

<em></em>

<em>Dad does 1 job in 5 hours.</em>

<em></em>

<em>In 1 hour, dad does 1/5 of the job.</em>

<em></em>

<em>Mom and dad working together do the job in x hours.</em>

<em></em>

<em>In 1 hour, mom and dad together do 1/x of the job.</em>

<em></em>

<em>1/3 + 1/5 = 1/x</em>

<em></em>

<em>5/15 + 3/15 = 1/x</em>

<em></em>

<em>8/15 = 1/x</em>

<em></em>

<em>8x = 15</em>

<em></em>

<em>x = 15/8 = 1.875</em>

<em></em>

<em>Answer: It takes them 1.875 hours.</em>

The graph shows the pounds of fruit and vegetables purchased by shoppers who bought both. (8th Grade Math)
vaieri [72.5K]

Because there is no pattern in the graph, we conclude that there is no correlation between the two variables, thus, the correct option is C.

<h3>What statement correctly describes the graph?</h3>

In the horizontal axis, we can see the pounds of fruit bought, while on the vertical axis we can see the pounds of vegetables bought.

If you see the graph, you can see that there is no pattern. Meaning that there is no relation between these two quantities.

So there is no correlation between the variables "pounds of fruit bought" and "pounds of vegetables bought.".

Then the correct option is C.

<em>"There is no association between the pounds of fruit purchased and the pounds of vegetables purchased"</em>
