Lesson 3-8. Write an equation for the line perpendicular to the given line through the given point.
Answer:
y = -3x + 14Step-by-step explanation:
Given line:
y = 1/3x - 2/5Perpendicular lines have negative-reciprocal slopes.
We will have a line:
y = -3x + bUse the coordinates of the given point to find the value of b:
-1 = -3(5) + b-1 = - 15 + bb = 14So the line is:
y = -3x + 14solve for y
2x+3y=r
(Show solving steps please)
2x + 3y = r
---Subtract 2x from both sides
3y = r - 2x
---Divide both sides by 3
y = (1/3)(r) - (2/3)(x)

1/5 + 2/6
Answer:
The common denominator is x30
Step-by-step explanation:
Answer:
[tex]30[/tex]
Step-by-step explanation:
The best choice for a common denominator will always be the least common multiple of the two denominators. In this case, the least common multiple of 5 and 6 is 30, so [tex]\boxed{30}[/tex] is the best choice.

Question is in the pic :)
Answer:
Since +P looks to be 7, -P would be -7
Hope this helps :)
Answer:
-7
Step-by-step explanation:
P is a variable, and P can only have 1 value. Thanks to the number line, we know what this value is. P is positive 7. If we know that the set value of P is positive 7, then we can just treat it like it is positive 7.
P - 5 = 2
P + 3 = 10
So putting a negative sign in front of P will mean it will be

Answer:
(0,-1); (0,-2); (2,0); (2,-2)
Step-by-step explanation:
when rotating 180 degrees all the points have their coordinate sign's flipped.
so the points go from:
(0,1) --> (0,-1)
(0,2) --> (0,-2)
(-2,0) --> (2,0)
(-2,2) --> (2,-2)
so your new shape will have the points (0,-1); (0,-2); (2,0); (2,-2)

The area of each small square is 16 square centimeters. What is the side length of the window? Explain
Answer:
Length=4 cm
Step-by-step explanation:
Solve for L
L*W=A
16 cm^2=L*W
Since this a square. W will equal L.
So [tex]\sqrt{16} =4[/tex]
Meaning that the length is 4
The area of a square is given by:
Area = Side²
If the area of a square is 16 square centimeters, the side length of the window is 4 cm.
What is a square?A square is a four-sided polygon, whose all sides are equal in length and whose opposite sides are parallel to each other.
We have,
Area of the square = 16 square centimeters
The area of a square is given as:
Area = side²
Area = 16 cm²
16 cm² = side²
Square root on both sides
[ 4² = 16 ]
√16 cm² = √side²
Side = 4 cm
Thus if the area of the square is 16 square centimeters, the side length of the window is 4 cm.

Step-by-step explanation:
let the 3 consecutive odd number be
x + 1 , x + 3 , x + 5
as, there sum is 45. so, after inserting the values we got,
→ x + x + 1 + x + 3 = 45
→ 3x + 9 = 45
→ 3x = 45 - 9 = 36
→ x = 36/3 = 12
→ x = 12
therefore, 3 consecutive odd number are
→ x + 1 = 12 + 1 = 13
→ x + 3 = 12 + 3 = 15
→ x + 5 = 12 + 5 = 17

suppose another line for a chair lift is placed at a constant distance c below the gondola line. what is the equation of the new line? is the new line also parallel to the hill? explain.
Answer:
Yes They are Parallel.
Step-by-step explanation:
The required equation of the line y = ax + c as of the old line and also the line is parallel to the hill.
Given that,
Suppose another line for a chair lift is placed at a constant distance c below the gondola line. the equation of the new line and is the line parallel to the hill is to be discussed.
A line is a straight curve connecting two points or more showing the shortest distance between the initial and final points.
Here,
The required new line is placed at a constant distance c below the gondola line,
If the line has a constant distance from the other line that implies that the line is parallel, and the equation of the line is given as,
y = ax + c
Thus, the required equation of the line y = ax + c as of the old line and also the line is parallel to the hill.

An elevator travels down from the top floor of a skyscraper. The graph below represents its height, in feet, over time in seconds. What does the slope of the line represent?
Answer:
So Y, which represents height, goes down depending on how far you are in time, which is X.
The slope of the graph represents the elevator's descent speed, calculated as 12 feet per second based on the points (1, 838) and (2, 826).
The Slope of the line in the graph represents the rate of change of height with respect to time, or the speed of the elevator's descent.
In this case, the slope can be calculated using the formula: slope = (change in height) / (change in time). We know that the elevator's height changes from 838 feet at 1 second to 826 feet at 2 seconds,
So, the change in height is : 838 - 826 = 12 feet, and the change in time is 2 - 1 = 1 second.
Therefore, the slope is 12 feet/second, this indicates that the elevator is descending at a speed of 12 feet per second.

A contractor needs to buy nails to build a house. The nails come in small boxes and large boxes. Each small box has 150 nails and each large box has 400 nails. The contractor bought 2 more small boxes than large boxes, which altogether had 1950 nails. Write a system of equations that could be used to determine the number of small boxes purchased and the number of large boxes purchased. Define the variables that you use to write the system.
Answer:
The number of small and large boxes purchased are:
2 small boxes.
6 large boxes.
Step-by-step explanation:
To solve the unknowns, two equations must be established with the information provided:
150X + 400Y = 2700 (the price of the boxes and the final number of nails, where X is the small boxes and Y the large boxes)
Y = 3X (Large boxes are triple the small ones)
Then equation 2 is replaced in equation one and variable X is cleared:
150X + 400 (3X) = 2700
150X + 1200X = 2700
1350X = 2700
X = 2700/1350
X = 2
Finally, the value of X is replaced in equation 2 to find the number of large boxes:
Y = 3X
Y = 3 (2)
Y = 6
