postnew [5]

Answer:

(9,126)

Step-by-step explanation:

Make sure x and y are on the same side

$0.5x+0.25y=36\\16x-1y=18$

Eliminate y by multiplying the first equation by 4 then adding both equations together

$2x+1y=144\\16x-1y=18\\18x=162\\x=9$

Plug the x value (9) into one of the equations

$16(9)-1y=18$

Solve

$16(9)-1y=18\\144-1y=18\\144=18+1y\\126=y$

x=9, y=126

Stem and leaf plots, what is the mode median and range of the scores

frez [133]

Answer:

Mode = 81, Median = 81 and Range = 39.

Step-by-step explanation:

The mode is the most occurring value which is 81.

The median is also 81. There are a total of 19 numbers arranged in ascending order so the median is the 10th number.

The range is the highest - lowest number = 100 - 61 = 39.

Beatrice calculated the slope between two pairs of points.

kumpel [21]

Answer:

The answer in the procedure

Step-by-step explanation:

we know that

The formula to calculate the slope between two points is equal to

$m=\frac{y2-y1}{x2-x1}$

step 1

Find the slope between (-3, -2) and (1, 0)

$m=\frac{0+2}{1+3}$

$m=\frac{2}{4}=\frac{1}{2}$

Find the equation of the line

$y-y1=m(x-x1)$

with m and the point (1,0)

substitute

$y-0=\frac{1}{2}(x-1)$

$y=\frac{1}{2}x-\frac{1}{2}$

step 2

Find the slope between (-2, -1) and (4, 2)

$m=\frac{2+1}{4+2}$

$m=\frac{3}{6}=\frac{1}{2}$

Find the equation of the line

$y-y1=m(x-x1)$

with m and the point (4,2)

substitute

$y-2=\frac{1}{2}(x-4)$

$y=\frac{1}{2}x-2+2$

$y=\frac{1}{2}x$

<em>Compare the equation of the two lines</em>

The two lines are parallel, because their slope is the same, but are different lines

therefore

Beatrice's conclusion is incorrect

All of these points are not on the same line, because are different parallel lines

The slope between (-2,-1) and (1,0) is equal to $\frac{1}{2}$

How did some businesses get the government to stay out of their affairs

inn [45]

Some of the businesses are successful in keeping government away from their affairs, by giving money to the Congress secretly.

<u>Explanation:</u>

Businesses which come to the attention of the government are those which doesn’t go by the rules or get flagged for not abiding by the rules. As the amendments in the policies are made modified time to time to serve the best interest of the public which needs to be followed very well.

But the business cannot be swapped overnight each time as it causes great damage to the structure of the business, so the business sort another way of settling the Congress by giving off money.
