The equation of a line for the given coordinates is 7x+2y+9=0.
The given coordinates are (1, -8) and (-1, -1).
We need to find the linear equation whose graph is a straight line.
What is the slope of a line?The slope of a line is defined as the change in the y coordinate with respect to the change in the x coordinate of that line. The slope of a line=m=(y2-y1)/(x2-x1).
Now, slope of the line=(-1-(-8))/(-1-2)
=7/(-2)
=-7/2
Now, put m=-7/2 and (-1, -1) in the equation y=mx+c.
So, -1=(-7/2)(-1)+c
⇒-1-7/2=c
⇒c=-9/2
Then the equation of the line=y=-7x/2-9/2
⇒2y=-7x-9
⇒7x+2y+9=0
Therefore, the equation of a line for the given coordinates is 7x+2y+9=0.

Two sides of a parallelogram are 49 feet and 78 feet. The measure of the angle
between these sides is 59º. Find the area of the parallelogram to the nearest square
foot.
Answer:
[tex]A=3276\ ft^2[/tex]
Step-by-step explanation:
Given that,
The sides of a parallelogram are 49 feet and 78 feet. The measure of the angle between these sides is 59º.
We need to find the area of the parallelogram.
Using trigonometry,
[tex]\sin(59)=\dfrac{h}{49}\\\\h=\sin(59)\times 49\\\\h=42.00\ ft[/tex]
We know that,
Area = base (b) × height (h)
So,
[tex]A=78\times 42.00\\\\A=3276\ ft^2[/tex]
So, the area of the parallelogram is equal to [tex]3276\ ft^2[/tex].

Drew's neighbor pays him $35 to mow
her lawn and she always gives him a 20%
tip. He decides to mow the lawn with his
friend and split the earnings evenly. How
much will each of them make?
Answer:
Step-by-step explanation:
Ok lets find 20% of 35 first.
20% of 35 is just 2 lots of 10%
10% of 35 is 3.5 if we move over the decimal
2 lots of 3.5 is 7
add the tip on
35 + 7 = 42
42 / 2 = 21
They each get $21

If you don't know that, you can use the change of base formula:
[tex]\log_2{\dfrac{1}{128}}=\dfrac{\log{\dfrac{1}{128}}}{\log{2}}=\dfrac{-2.1072}{0.30103}=\boxed{-7}[/tex]

The volume would be the area of the triangle x the length (r)
Find the area of the triangle:
Area of triangle = 1/2 x base x height
Area = 1/2 x 7 x 4 = 14 m^2
To find r, divide the volume by the area of the triangle :
R = 112/14 = 8
The answer is 8 m

what is the height of the tree
A. 156 ft
B. 100 ft
C. 80 ft
D. 25 ft
Answer:
B
Step-by-step explanation:
You first must find the conversion rate. Since you know a 4 ft tall object produces a 5 foot long shadow, you simply divide 4 by 5. This gives you 0.8. Now that you have your conversion rate, you multiply it by the shadow the tree casts, that being 125, and your answer is B, 100.

X
Answer:
x = 8
Step-by-step explanation:
For the triangles to be similar then the ratio of corresponding sides must be equal, that is
[tex]\frac{DF}{XZ}[/tex] = [tex]\frac{EF}{YZ}[/tex] , substitute values
[tex]\frac{2x-5}{22}[/tex] = [tex]\frac{6}{12}[/tex] ( cross- multiply )
12(2x - 5) = 132 ( divide both sides by 12 )
2x - 5 = 11 ( add 5 to both sides )
2x = 16 ( divide both sides by 2 )
x = 8
