To find the slope of a line perpendicular to another line, we simply need to find the inverse negative of the slope of the first one. This makes sense if you visualize it on a graph or in your head.
The slope of the line given is -1/2.
To find the inverse negative we first inverse the number, then take then negatuve of that (or opposite order).
The inverse of -1/2 is, -2 (switch the numerator and denominator or do to the power of -1, ^-1).
The negative of -2 is, 2.
Therefore the slope of the line perpendicular to y = -1/2x + 5 is 2.

Sierra has plotted two vertices of a rectangle at (3,2) and (8,2). What is the length of the sides of the rectangle
Answer:
5units
Step-by-step explanation:
Given the two vertices of a rectangle at (3,2) and (8,2). We are to calculate the distance between the two points.
Using the formula
D = √(x2-x1)²+(y2-y1)²
D = √(2-2)²+(8-3)²
D = √0+5²
D = √25
D = 5
Hence the length of the side of the rectangle is 5units

Use the distance formula to find the distance between each PowerPoint round to the nearest 10th if necessary
Answer:
Step-by-step explanation:
Distance between two points [tex](x_1,y_1)[/tex] and [tex](x_2,y_2)[/tex] is given by the formula,
Distance = [tex]\sqrt{(x_1-x_2)^2+(y_1-y_2)^2}[/tex]
a). A(-6, -4), B(-3, -1)
Distance between A and B = [tex]\sqrt{(-6+3)^2+(-4+1)^2}[/tex]
= [tex]\sqrt{9+9}[/tex]
= 3√2
= 4.2 units
b). C(3.5, 1), D(-4, 2.5)
Distance between C and D = [tex]\sqrt{(3.5+4)^2+(1-2.5)^2}[/tex]
= [tex]\sqrt{58.5}[/tex]
= 7.65
≈ 7.7 units
c). Distance between X(5, -5) and Y(-5, 5)
Distance = [tex]\sqrt{(5+5)^2+(-5-5)^2}[/tex]
= [tex]\sqrt{200}[/tex]
= 10√2
= 14.14
≈ 14.1 units
Mrs. Leary wants to buy some plants and potting soil. Each plant costs $2.50 and each bag of potting soil costs $3.25. Mrs. Leary wants to spend no more than $50. If Mrs. Leary buys 4 bags of potting soil, which inequality represents the number of plants, p, that she may buy?
Answer: Ok while i was working out this problem I started by multiplying so i started by 5
2.50 x 5 = 12.5
3.25 x 5 = 16.25 then I added then and got 28.75. So i was like i should go higher. I picked 7.
2.50 x 7 = 17.5
3.25 x 7 = 22. 75 then I added those two and got 40.25 when i got that I was like yes, Im getting closer. So i picked 9 then I got..
2.50 x 9 = 22.5
3.25 x 9 = 29.25 and that equaled 51.75
so then i was like oh! Taxes so I think the answer might be 8. 46 plus tax lol.

1) Mark and Huong are selling flower bulbs for a school fundraiser. Customers can buy packages
tulip bulbs and packages of crocus bulbs. Mark sold 9 packages of tulip bulbs and 1 package of
crocus bulbs for a total of $127. Huong sold 6 packages of tulip bulbs and 6 packages of crocus
bulbs for a total of $186. Find the cost each of one package of tulips bulbs and one package of
crocus bulbs.
Answer:
Package of tulip bulbs = $12
Package of crocus = $19
Step-by-step explanation:
Let b = cost of a package of bulbs
c = cost of a crocus package
Mark: (1) 9b + c = 127 Huong: (2) 6b + 6c = 186
c = 127 - 9b 6b + 6(127 - 9b) = 186
6b + 762 - 54b = 186
- 48b = -576
b = 12
c = 127 -9(12)
c = 127 - 108 = 19

Solve the equation above for X.
Answer:
[tex]\large\boxed{\tt x = 444.}[/tex]
Step-by-step explanation:
[tex]\textsf{We are asked to solve for x in the given equation.}[/tex]
[tex]\textsf{Note that our goal is to leave x alone on the left side of the equation. In order}[/tex]
[tex]\textsf{to do so we will need to use the \underline{Properties of Equality}.}[/tex]
[tex]\large\underline{\textsf{What are the Properties of Equality?}}[/tex]
[tex]\textsf{Properties of Equality are 9 Properties that allows us to manipulate equations}[/tex]
[tex]\textsf{to, commonly find unknown variables or to determine if equations are true.}[/tex]
[tex]\textsf{For our problem, we will be using 2 out of 9 of these properties as we need to}[/tex]
[tex]\textsf{isolate x, and make sure x is 1x.}[/tex]
[tex]\large\underline{\textsf{Solving for x;}}[/tex]
[tex]\tt \frac{1}{2} x-41=181[/tex]
[tex]\textsf{Let's first use the Addition Property of Equality where the equation will be equal}[/tex]
[tex]\textsf{if we add the same number to both sides of the equation. Let's start by adding}[/tex]
[tex]\textsf{41 to both sides of the equation.}[/tex]
[tex]\tt \frac{1}{2} x-41+41=181+41[/tex]
[tex]\tt \frac{1}{2} x = 222[/tex]
[tex]\textsf{Next, let's use the Multiplication Property of Equality where the equation is}[/tex]
[tex]\textsf{equal if we multiply the same number to both sides of the equation. Let's}[/tex]
[tex]\textsf{multiply 2 to both sides of the equation to cancel out} \ \tt \frac{1}{2} .[/tex]
[tex]\tt 2 \times \frac{1}{2} x = 222 \times 2[/tex]

-2x=-30
x=-15
4 x -15= -60
angle 3 =59 degrees
angle 6= 119 degrees
Find the percent of the number. 140% of 60 is
100% of 60 = 60
100%=60
140% of 60 = x
140%=x
60/x = 100/140
(cross multiplication)
x = 84
140% of 60 = 84

The population of a town is 75 000 and decreases 15% each year. Complete the exponential function that models the population afterx years
f(x) = 75,000
Answer:
Step-by-step explanation:
This is an exponential function of the form:
[tex]y=a(1-r)^x[/tex] where a is the initial value and (1 - r) is the growth rate (which in our case is a decay, actually!). Our initial value is 75000 and our rate of change in the population is 15% or .15. Filling in our model:
[tex]y=75000(1-.15)^x[/tex] and simplifying:
[tex]y=75000(.85)^x[/tex] This turns out to be a decay problem because the value inside the parenthesis is less than 100%.
x is our time, so the model is as stated above.
