Answer:
The answer is y = 4x - 1
Step-by-step explanation:
First find two points on the line.
I will be using (-1, -5) & (1, 3).
Using the formula for slope, substitute in the values and solve:
y2-y1/x2-x1(This is the formula)
3--5/1--1(When using this formula, if y1 or x1 are negative, make them positive.)
3+5/1+1 or 8/2; which simplifies into 4/1.
So, the slope is 4/1.
Now we use point-slope form:
y - y1 = m(x-x1)
1. Substitute in the values.
y--5 = 4/1(x--1)
2. Simplify and distribute.
y + 5 = 4/1x + 4
3. Subtract 5 from both sides.
y = 4/1x - 1
4. Simplify.
y = 4x - 1
Answer:
The height of the pyramid is 
Step-by-step explanation:
we know that
The volume of the pyramid is equal to
where B is the area of the base of the pyramid
h is the height of the pyramid
we have
----> the area of the base is the area of a rectangle
substitute the values in the formula and solve for h
I the answer is C I’m not really sure but I’ll update u when i get the answer
For both problems, we can use the section formula.
1) 
2) 
W - a width
3w - a length
27 ft² - an area
Therefore:
w · 3w = 27
3w² = 27 |:3
w² = 9 → w = √9 → w = 3
3w = 3 · 3 = 9
width = 3
length = 9
The perimeter:
P = 2 · width + 2 · length
P = 2 · 3 + 2 · 9 = 6 + 18 = 24 ft.
