The parking garage for a building is underground. Kennedy parks her car 4 floors below ground level. She plans to walk to the 3rd floor of the office building from her car. If she uses the stairs to walk from her car to the 3rd floor of the building, how many floors will she travel?
Answer:
5 flights of stairs
Step-by-step explanation:
The car is 4 floors below ground so she walks 4 to get to ground level. Then she walks 3 more to get to where she is going.
4 + 3 = 7 total floors
Write an equation in standard form of the line that passes through (4,−1) and has the slope m=3.
Answer :
m = 3
Point = (4,-1)
x1 = 4
y1 = -1
Formula =
y - y1 = m (x-x1)
y - (-1) = 3 (x -4)
y + 1 = 3x -12
y - 3x + 1 + 12 = 0
y - 3x + 13 = 0
The line = y - 3x + 13 = 0 or -3x + y + 13 = 0
I'm sorry if I'm wrong.

y=3x-13 is the equation in standard form of the line that passes through (4,−1) and has the slope m=3.
What is Slope of Line?The slope of the line is the ratio of the rise to the run, or rise divided by the run. It describes the steepness of line in the coordinate plane.
The slope intercept form of a line is y=mx+b, where m is slope and b is the y intercept.
The slope of line passing through two points (x₁, y₁) and (x₂, y₂) is
m=y₂-y₁/x₂-x₁
m=3
We need to find slope intercept form, for this we should know the y intercept with slope m =3 and point (4,-1)
-1=3(4)+b
-1=12+b
-1-12=b
b=-13
y intercept is -13
Hence, y=3x-13 is the equation in standard form of the line that passes through (4,−1) and has the slope m=3.

Pool #1 is a rectangle that is 14 feet wide. The length is (14– 8)2ft.
The dimensions of the pool are: Length=________ ft Width=_________ft
Answer: the length is 6 feet. The width is 2 feet
Step-by-step explanation:
The garden pool is rectangular in shape.
Let L represent the length of the rectangular garden.
Let W represent the width of the rectangular garden.
The area of a rectangle is expressed as L× W. The area of the rectangular garden pond is 12ft^2. It means that
L× W = 12 - - - - - - - - - - 1
The length of the pool needs to be 2ft more than twice that width. This means that
L = 2W + 2 - - - - - - - - - - - 2
Substituting equation 2 into equation 1, it becomes
W(2W + 2) = 12
2W^2 + 2W = 12
2W^2 + 2W - 12 = 0
W^2 + W - 6 = 0
W^2 + 3W - 2W - 6 = 0
W(W + 3) - 2(W + 3) = 0
W - 2 = 0 or W + 3 = 0
W = 2 or W = - 3
Since the Width cannot be negative, then the width is 2 feet
Substituting W = 2 into equation 2. It becomes
L = 2×2 + 2 = 6 feet

What is this answer?
Answer:
$ 30.8Step-by-step explanation:
ratio and proportion:
3 tickets = 7 tickets
$13.20 x
then cross multiply: 3 (x) = 13.20 (7)
simplify: 3x = 92.4
solve for x = 92.4 / 3
x = $ 30.8
therefore,

I need help finding the slope, the y-intercept and the equation?
Answer:
y is (0,-2) thats all i know sorry
Step-by-step explanation:
The equation of line will be;
⇒ y = x + 2
And, The y - intercept will be 2.
What is Equation of line?
The equation of line with slope 'm' and y - intercept at point 'b' is given as;
⇒ y = mx + b
Given that;
The points on the graph are (0, 2) and (- 2, 0).
Now,
Since, The equation of line passing through the points (x₁ , y₁) and (x₂, y₂) with slope 'm' is defined as;
y - y₁ = m (x - x₁)
Where, m = (y₂ - y₁) / (x₂ - x₁)
Thus, The slope of the line with the points (0 , 2) and (-2, 0) is;
m = (0 - 2) / (- 2 - 0)
m = - 2/- 2
m = 1
So, The equation of line passing through the points (0 , 2) and (-2, 0) with slope 1 is defined as;
y - y₁ = m (x - x₁)
y - 2 = 1 (x - 0)
y - 2 = x
y = x + 2
Now, Compare with the equation y = mx + b, we get;
The y - intercept = 2
Thus, The equation of line will be;
⇒ y = x + 2
And, The y - intercept will be 2.

Find the variation constant and an equation of variation for the given situation.
y varies directly as x, and y = 7 when x = 1/2.
Answer:
[tex]\displaystyle y=14\cdot x[/tex]
Step-by-step explanation:
Directly Proportion
It's said that y varies directly proportional as x, if:
[tex]y=k\cdot x[/tex]
Where k is a constant of proportionality.
We know that y=7 when x=1/2.
Using the above condition, we can find the value of k:
[tex]\displaystyle 7=k\cdot \frac{1}{2}[/tex]
Solving for k:
k=14
Thus, the equation is:

Find x- and y-intercepts. Write ordered pairs representing the points where the line crosses the axes.
y= 1/3 x− 2/3
Answer:
y-intercept = (0,-2/3)
x-intercept = (2,0)
Step-by-step explanation:
*X-intercept touches the x-axis & y-intercept touches the y-axis*
You can identify the y-intercept by looking at the equation.
The slope is 1/3x and the y-intercept is -2/3.
I'm not sure how to solve for the x-intercept, but you can make a graph with the y-intercept and the slope points. By doing this you should be able to find the x-intercept.
Hope this helped!!! :)

h=4.8
Given:
area=24 , a=4 , b=6
To find:
height
Step-by-step explanation:
A = [tex]\frac{1}{2}[/tex] × h(a+b)
24 = [tex]\frac{1}{2}[/tex] × h(4+6)
24 × 2 = h(10)
48 = 10h
48/10 = h
h=24/5
h=4.8
therefore, height of the trapezium is 4.8
