Answer:
y=5/2x-16
Step-by-step explanation:
First, we want to find the slope of the original line.
m= -4+8/-1-9
m= 4/-10
m= -2/5
Because we want the perpendicular bisector, we will need the slope to be the opposite reciprocal. Therefore, our slope is
m=5/2
Now, we want to find the midpoint of the line.
9-1/2
8/2=4
-8-4/2
-12/2= -6
So, the midpoint is (4,-6)
Using the information we have, we now can find b.
-6=5/2(4)+b
-6=10+b
-16=b
That gives us our equation
y=5/2x-16

what is 31 billion in scientific notation?
explain clearly <3 :D
Answer:
3.1*10^10
Step-by-step explanation:
31 billion would be written like that because... there are 9 0's left, and that goes up to 10 because i turned 31 to 3.1 not 31, so that value after a decimal point adds 1

Luis charges a travel fee of $10 plus $25 per month to mow his neighbors' lawns. If most of his customers only get their lawns mowed for 5 to 8 months out of the year, what is the RANGE of this situation?
Answer:
135 to 210
Step-by-step explanation:
Given
[tex]Base\ Charge = 10[/tex]
[tex]Additional\ Charge = 25[/tex] monthly
Months = 5 to 8
Required
Determine the range of the function
First, we need to determine the function equation.
Let total charges be y and months be x
[tex]y = Base\ Charge + Additional\ Charge * x[/tex]
[tex]y = 10 + 25 * x[/tex]
[tex]y = 10 + 25x[/tex]
When x = 5:
[tex]y = 10 + 25 * 5[/tex]
[tex]y = 10 + 125[/tex]
[tex]y = 135[/tex]
When x = 8
[tex]y = 10 + 25 * 8[/tex]
[tex]y = 10 + 200[/tex]
[tex]y = 210[/tex]
Hence, the range is 135 to 210

Step-by-step explanation:
Cesar has 32 boxes of pasta and 48 jars of sauce that he will be putting into bags for a food drive. He wants each bag to have the same amount of pasta and sauce and wants to use all of the items. Use the drop-down menus to complete the statements below about the number of bags Cesar can make.
Cesar has 32 boxes of pasta and 48 jars of sauce that he will be putting into bags for a food drive. He wants each bag to have the same amount of pasta and sauce and wants to use all of the items. Use the drop-down menus to complete the statements below about the number of bags Cesar can make.
What is the greatest number of bags Cesar can make and Each bag would have _____ pasta and _____ jars of sauce
Answer:
The greatest number of bags Cesar can make is 16 bags.
Each bag would have 2 pasta and 3 of jars of sauce
Step-by-step explanation:
We solve the above question using Greatest Common Factor method
The factors of 32 are: 1, 2, 4, 8, 16, 32
The factors of 48 are: 1, 2, 3, 4, 6, 8, 12, 16, 24, 48
Then the greatest common factor is 16.
Hence, the greatest number of bags Cesar can make is 16 bags.
For Pasta, We have 32 pasta
Each bag would have: 32/16
= 2 pasta
For Jars of sauce, we have 48 jars of sauce.= 48/16
= 3 jars of sauce

John is buying food for his cat, Fluffy. Fluffy LOVES a fancy wet food which costs $1.50 per day. Fluffy will also tolerate dry food which is $0.75 per day. John wants to spend at most $9.00 on cat food each week
Answer:
The answer is below
Step-by-step explanation:
Let x represent the number of days that fluffy eats wet food in a week and y represents the number of days that fluffy eats dry food in a week.
Hence:
x + y = 7 (1)
Also, John wants to spend at most $9.00 on cat food each week. Hence:
1.5x + 0.75y ≤ 9 (2)
The list of possible points after solving graphically are:
(0,7), (6,0), (0,12) and (5, 2). If x,y > 0, then the point that satisfies the inequality is:
(5, 2) i.e. 5 wet food and 2 dry food
Help!!!! I will give brainliest.
Answer:
Step-by-step explanation:
Well lets try to simplify this.
-3y= -4x +17
y=4/3 x - 17/3
Thus y-int is (0, -17/3)
To solve for x-int, y=0
y=4/3 x - 17/3
0=4/3 x - 17/3
4/3 x = 17/3
x=17/4
Thus x-int is (17/4, 0)

To simplify the expression, we need the trigonometric identities given:
we know that,
1. cot=1/tan
2. tan=sin/cos
3. sec=1/cos
so, we have,
cot θ sec θ sin θ = 1/tanθ(1/cosθ)sinθ
= (1/(sinθ/cosθ))(1/cosθ)sinθ
= (cosθ / sinθ) (1/cosθ)sinθ
= 1
The expression is equal to 1.

Apple pies have 8 pieces and cost $7. You only have $191 left in your budget. How many of each type of pie should you hut
Answer:
Step-by-step explanation:
You are planning a thanksgiving fest for all your family and friends. You invite 224 people. You plan to have a piece of pie for each guest. You only have $191 left in your budget. How many of each type of pie should you hut
Let the number of pumpkin pies = p
The number of apple pies = a
Pumpkin pies have 6 pieces and cost $5. Apple pies have 8 pieces and cost $7.
Hence:
p + a = 224 people
p = 224 - a
$5 × p + $7 × a = $191
5p + 7a = 191..... Equation 1
Substitute 224 - a for p in Equation 1
5(224 - a) + 7a = 191
1120 - 5a + 7a = 191
- 5a + 7a = 191

Answer:
The base is 0.1
The base is less than 1 so the function is decreasing
The x intercept is (3,0)
Step-by-step explanation:
The base of a logarithm refers to the number that must be raised to the power of the number on the right hand side of the logarithmic equation in order to yield the number on the left hand side of the logarithmic equation. It is always written as a subscript below the log symbol. In this case, the base is 0.1.
When the base of a logarithm is less than 1, it means that the function is decreasing as is the case in this question.
Looking at the graph, the x axis is cut at the point (3,0). This is the x-intercept of the graph.
Find the value of x that makes m || n
Answer:
a) 24
Step-by-step explanation:
To make m//n, the sum of co-interior angles (4x + 84) should be 180
4x + 84 = 180
4x = 180 - 84
4x = 96
x = 96/4
x = 24

samantha works at a nursery, where she pots plants. it takes her 1 1/2 hours to pot 12 plants.
how many plants can samantha pot in 1 hour?
12 (operation i dont know) n = (the number of plants she can pot in 1 hour)
Answer:
She could plant 9 plants.
Step-by-step explanation:
1 1/2 hours = 90 minutes, so 12 plants per 90 minutes. Which would mean 6 plants per 45 minutes. So in between 45 and 90 minutes (1 hour), and in between 6 and 12 plants (9).
Sorry if you didn't understand, I'm bad at explaining.
