Answer:

the equation to find the slope is (y2-y1)/(x2-x1)

the points are (-1,2) and (2,2) so plug it in and you get

(2-2)/(2-(-1))

0/ (2+1)

0/3

whenever the numerator is 0, that means the slope is 0. the line is just a horizontal line.

Someone help, I just need the answers, no explanation or non of that

Answer:

5). x = 15

7). JL = 78

Step-by-step explanation:

We can solve these problems with the help of midsegment theorem.

Midsegment theorem:

"Segment joining midpoints of two sides of a triangle is parallel and half the measure of third side of the triangle"

Question 5

8x - 23 = $\frac{1}{2}(10x+44)$

8x - 23 = 5x + 22

8x - 5x = 22 + 23

3x = 45

x = 15

Therefore, x = 15 is the answer.

Question 7

Since, MN is the midsegment,

MN = $\frac{1}{2}(JL)$

5x - 16 = $\frac{1}{2}(4x+34)$

5x - 16 = 2x + 17

5x - 2x = 17 + 16

3x = 33

x = 11

Therefore, Length of JL = 4(11) + 34

= 44 + 34

= 78 units

The entry fee at a small fair is $1.50 for children and $4.00 for adults. On a certain day, 2200 people enter the fair and $5000

Sauron [17]

Answer:

The number of children attended the fair is 1520.

Step-by-step explanation:

We are given the following in the question:

Entry fee foe children = $1.50

Entry fee foe adult = $4.00

Total number of people in fair = 2200

Total money collected = $5000

Let x be the number of children and y be the number of adults in the fair.

Then, we can write the following equations:

$x + y = 2200\\1.5x + 4y = 5000$

Solving the two equations, we have:

$1.5x + 1.5y = 3300\\1.5x + 4y = 5000\\\Rightarrow 2.5y = 1700\\y = 680\\x = 2200-680 = 1520$

Thus, there were 1520 children and 680 adults in the fair.
