Find the coordinates of the intersection of the diagonals of parallelogram GHJK with vertices G (1,3) H (4,3) J (5,1) and K (2,1)
Answer: (3,2)
Step-by-step explanation: Diagonal is a line connecting two opposite points of a form. In parallelograms, there two diagonals and they bisect each other, i.e., the point where the diagonals meet divide them into two segments with the same measure. In short, diagonals meet at their midpoint.
The way to determine midpoint is given by
(x,y) = [tex]{\frac{x_{1}+x_{2}}{2} },\frac{y_{1}+y_{2}}{2}[/tex]
(x,y) = [tex]{\frac{1+5}{2} },\frac{3+1}{2}[/tex]
(x,y) = (3,2)
The coordinates where diagonals of parallelogram GHJK intersect are (3,2).

Answer:
x = - 8/23
y = 40/23
Step-by-step explanation:
-5x- y = 0
and
-8x+3y = 8
The first step to solve this would be to get what one of the two variables equal. The easiest in this case is y from the first equation.
-5x-y = 0
-y = 5x
y = - 5x
Now you can take this y value and plug it into the section equation.
-8x + 3(-5x) = 8
-8x - 15x = 8
-23x = 8
x = - (8/23)
Once you get the x value you can plug it back into equation one to get y's value
-5*-(8/23) - y = 0
40/23 - y = 0
y = 40/23

Step-by-step explanation:
Answer:
C. 35 sq. units
Step-by-step explanation:
in order to find the area of a triangle you have to use the formula
1/2 b h
b as in base
h as in height
so if we use the measurements on the triangle and we plug that in we will get
1/2 x 14 (the base) x 5 (the height)
therefore giving us 35 sq. units.

For glass, calculate the average rate of change between 1970 and 1980. Then interpret what this value means.
a.
From 1970 to 1980, the number of pounds of glass per person per day decreased by 0.002 per year.
c.
From 1970 to 1980, the number of pounds of glass per person per day increased by 0.002 per year.
b.
From 1970 to 1980, the number of pounds of glass per person per day decreased by 0.11 per year.
d.
From 1970 to 1980, the number of pounds of glass per person per day increased by 0.11 per year.
The correct option regarding the average rate of change for glass is given by:
c. From 1970 to 1980, the number of pounds of glass per person per day increased by 0.002 per year.
What is the average rate of change of a function?It is given by the change in the output divided by the change in the input.
Looking at the table, in the 10 years from 1970 to 1980, the amount of glass changed from 0.34 pounds to 0.36 pounds, hence the rate is given by:
r = (0.36 - 0.34)/10 = 0.02/10 = 0.002.
Which means that option c is correct.
