Answer:
D) y-7=-6/11(x+7)
Step-by-step explanation:
m=(y2-y1)/(x2-x1)
m=(1-7)/(4-(-7))
m=-6/(4+7)
m=-6/11
y-y1=m(x-x1)
y-7=-6/11(x-(-7))
y-7=-6/11(x+7)
y=-6/11x-42/11+7
y=-6/11x-42/11+77/11
y=-6/11x+35/11

The formula for the perimeter, P, of a rectangle is P = 2(l + w), where l represents the length and w represents the width.
A. Todd has a string that is 26 inches long and wants to create a 9-inch-long rectangle with it. Substitute these values into the formula above, and solve for w to determine how wide Todd’s rectangle must be. Show your work.
B. Todd solved for the width arithmetically, as follows:
The length of the rectangle is 9 inches, so the sum of the lengths of the two long sides is 2 • 9 = 18 inches.
The string is 26 inches long, and 18 inches are used for the long sides of the rectangle, so the number of inches available for the short sides is 26 − 18 = 8 inches.
A rectangle has 2 congruent short sides, so the length of each short side, or the width of the rectangle, is 8 ÷ 2 = 4 inches.
Describe how Todd’s arithmetic solution process is similar to your algebraic solution process from part A, and how they are different.
C. The perimeter formula can be solved for w, in terms of P and l, as shown below.
P = 2(l + w)
P = 2l + 2w
P − 2l = 2w
= w
Explain why it could be useful to solve the perimeter equation for w in terms of P and l.
Answers
Answer:
p= 2L + 2w

volume of a pyramid with a square base of length 5m is 75m³. Find it's hieght
Answers
Answer:
The height of the pyramid is 3 m.
Step-by-step explanation:
Given;
volume of pyramid, V = 75 m³
length of the square, L = 5 m
The volume of a pyramid is given as;
V = area of the square base x height
V = Ah
where;
A = L² = 5 x 5 = 25 m²
h = V/A
h = (75) / (25)
h = 3 m
Therefore, the height of the pyramid is 3 m.

[tex](5x-3y)[/tex] and [tex](8x+8y)[/tex]
To find:
The difference of [tex](5x-3y)[/tex] and [tex](8x+8y)[/tex].

Answers
The simple interest for the principal amount of $600 at the rate of 4% for 9 months will be equal to $216.
What is Simple interest?A quick and simple way to figure out interest on that money is to use the simple interest approach, which adds interest at the same rate for each daily cycle, and it is to the initial principal amount. A way to figure out how much interest will be charged on an amount of money at a specific rate and for a specific duration of time is by using simple interest.
As per the given information in the question,
Principle amount, P = $600
Time, T = 9 months
Rate, R = 4%
SI = (600 × 9 × 4)/100

Salvador has a rug in his bedroom with perimeter of 36 feet, the length of the rug is 8 feet what is the width of the rug?
Answers
Answer:
10 feet
Step-by-step explanation:
Salvador has a rug in his bedroom with perimeter of 36 feet, the length of the rug is 8 feet what is the width of the rug?
The rug is shaped as a rectangle
The formula for the Perimeter of a rectangle = 2L + 2W
Perimeter = 36 feet
Length = 8 feet
Hence
36 = 2(8) + 2W
36 = 16 + 2W
2W = 36 - 16
2W = 20
W = 20/2
W = 10 feet
Therefore, the Width of the rug is 10 feet

just in case if line AC and BD are straight lines,
angle EGD will be 180-90-30=60
and EGD will equal to x°becoz they are just in opposite
Answer:
The Answer is 60
Step-by-step explanation:
If you look at E B and F those make up a 180-degree angle if you look across from B then you will see that it is a 90-degree angle so you can assume that B is also a 90-Degree angle so if you add up 30 + 90 = 120
You then can subtract 180 - 120 to get the answer 60
So therefor the answer is 60
