Hey there!

Three points to keep in mind!

The given options are in standard form: ax+by=c
The line is a solid line, hence, the possible outcomes would be ≤ or ≥
The shaded part is above the line, hence, the symbol would be ≥

First, let's find the slope:

Slope : (y2-y1)/(x2-x1)

Slope : (0-3)/(2-0)

Slope : -3/2

Looking at line, we know that the y-intercept is 3 b=3

Slope intercept form:

Let's now convert this into a standard form:

<em>Multiplying all the sides with 2: </em>

<em>Remember that the coefficient of 'x' shall not be negative or a fraction!</em>

<em>3x+2y≥6 </em><em>is the final answer!</em>

Which statement is true? <br><br><br> Help please.

Every point on a line satisfies the equation of that line.
If two lines intersect at one point, that point is a point on both lines, so it must satisfy both lines. Since two different lines can intersect at most at one point, that point is the only point that makes the two equations true.

Natalie picks 40 bushels in 12 hours and Mary can pick the same amount in 11 hours. how long would it take if they worked togeth

rosijanka [135]

Answer: $5.73\ hours$ or $5\ hours\ and\ 44\ minutes$

Step-by-step explanation:

You can use the following work-rate formula:

$\frac{t}{t_A}+\frac{t}{t_B}=1$

In this case let be ${t_A}$ the time it takes for Natalie to pick 40 bushels, ${t_B}$ the time it takes for Mary to pick 40 bushels and $t$ the time it takes to pick 40 bushels if they work together.

Based on the information given in the exercise, you can identify that:

$t_A=12\\\\t_B=11$

Then, knowing this values, you need to substitute them into the formula:

$\frac{t}{12}+\frac{t}{11}=1$

Finally, you must solve for "t" in order to find its value.

The result is:

$t(\frac{1}{12}+\frac{1}{11})=1\\\\t(\frac{23}{132})=1\\\\t=\frac{132}{23}\\\\t=5.73\ hours$

Since $1\ hour=60\ minutes$ :

$(0.73\ hours)(\frac{60\ minutes}{1\ hour})\approx44\ minutes$

Therefore it would take 5 hours and 44 minutes to pick 40 bushels if they worked together.

Over the first five years of owning her car, Gina drove about 12,100 miles the first year, 15,758 miles the second year, 12,200

grandymaker [24]

To find the mean, add up all of the miles and divide by the number of years. 12100 + 15758 + 12200 + 11800 + 12750 = 64608.   64608/5 = 12921.9. The mean (the average) is 12,921.9 miles.

To find the median, put the numbers in order and find the middle number. The middle number is 12200.  The median (middle number) is 12,200 miles

To find the mode, you would look for the number that is repeated the most. In this data set, no number repeats, so there is no mode.  There is no mode for this data set.

The mean (average) would be the best measure of central tendency to predict how many miles Gina will drive in the sixth year.

I hope this helps! Can I have Brainliest, please? :)

Adam lived a quarter of his life as a boy as fifth as a young man, a third in middle-age and 13 years in retirement. How old was

Anika [276]

ANSWER

Find out the how old was we when he died.

To proof

Let us assume that the age of the Adam be x

As given

Adam lived a quarter of his life as a boy as fifth as a young man, a third in middle-age and 13 years in retirement.

$x =\frac{x}{4} +\frac{x}{5} +\frac{x}{3} + 13$

L.C.M of denominator i.e ( 4,5,3) =60

than the equation becomes

60x = 15x + 12x +20x +780

60x - 47x = 780

13x = 780

$x =\frac{780}{13}$

x = 60 years

therefore the Adam age when he died is 60 years.

Hence proved

How do you solve this question: what is the difference between (2,5) and (2,0) without using a coordinate plan graph?

IrinaK [193]

Answer: (2,5) is 5 units above (2, 0)

Step-by-step explanation: The first point has a 5 in the y-axis (up and down) while the second point is on the x-axis
