if P1 is (3,-3) and the midpoint is (-2,1), what are the points of P2?
Step-by-step explanation:
Hey there!
The points P1(3,-3) and midpoint is (-2,1). Let (X,y) be the end point.
Note: Find through using midpoint formula.
midpoint = ( \frac{x1 + x2}{2} , \frac{y1 + y2}{2} )
Put all values.
(\frac{X+3}{2},\frac{-3+y}{2})
Since they are equal, equating with it's corresponding components.
\frac{3 + x}{2} = - 2
-2 = 3 + x
-4 -3= x
Therefore, X= -7.
Now,
[tex] \frac{ - 3 + y}{2} = 1[/tex]
[tex] - 3 + y = 2[/tex]
Therefore, y= 5
Therefore, the other end point is (3,5).

Step-by-step explanation:
first you figure out the 2 angles the triangle is missing so 28-90 would be 62
then to find the other unknown angle you solver for the larger triangle
so 90+48=138
180-138=42
42+62=104
104+2y-30=180
add 30
104+2y=210

Answer:

let's say that

. Your function

, since
g

Based on this, to find the function for

(combined from right to left, by the way), simply replace

How many complete rotations does the minute hand of a clock make as it moves from 12:00 noon to 4:00 p.m.? rotations
Answer:
60 x 4 = 240 times
Step-by-step explanation:
In every hour there are 60 minutes.
That means for every hour the minute hand moves 60 times
Take the amount of hours and times it by 60 ( Hours x 60 )
The minute hand of the clock completes 4 rotations as it moves from 12:00 noon to 4:00 p.m
What is complete rotation of minute hand ?In a clock there are second hand, minute hand and hour hand, all rotates anticlockwise. If the minute hand come at the same place after start rotating from that place , then the rotation is called one complete rotation.
Since 1 complete rotation of a minute hand takes 60 minutes, which is one hour.
Therefore, In one hour the minute hand completes one rotation.
Thus, after first complete rotation of minute hand the time will be 1:00 p.m.
After two complete rotation of minute hand the time will be 2:00 p.m.
After three complete rotation of minute hand the time will be 3:00 p.m.
Similarly, after four complete rotation of minute hand the time will be 4:00 p.m.
Hence it takes 4 complete rotation of a minute hand to moves from 12:00 noon to 4:00 p.m.

Diego pays $4.50 for 3 pounds of bananas and 2 pounds of oranges. One pound of oranges cost $0.75 more than one pound of bananas let b represent the price per pound of bananas. Which equation represents the situation, and what is the price per pound of each fruit?
Answer:
Kindly check explanation
Step-by-step explanation:
Given that:
Let banana = b
Oranges = a
3b + 2a = 4.50 - - - (1)
a = 0.75 + b - - - (2)
Substitute (2) into (1)
3b + 2(0.75 + b) = 4.50
3b + 1.5 + 2b = 4.50
5b = 4.50 - 1.50
5b = 3
b = 3/5
b = $0.6
a = 0.75 + 0.6
a = $1.35

plss someone help my do this problem (a^14 • a^-6 / a^25)^3
Answer:
[tex]a^{-51} = \frac1{a^{51}}[/tex]
Step-by-step explanation:
When you're multiplying two powers with the same base (in our case, a) you add together the exponents.
[tex](\frac{a^1^4\cdot a^-^6}{a^{25}})^3 =\\(\frac {a^{14+(-5)}}{a^2^5})^3= (\frac {a^{14-6}}{a^2^5})^3 = (\frac {a^{8}}{a^2^5})^3[/tex]
Now, when you are dividing two powers with the same base (in our case, a again) you subtract the exponents:
[tex]= (a^{8-25})^3 = (a^{-17})^3[/tex]
Finally, when you're calculating the power of a power, you multiply the exponents together:
[tex]a^{-17\cdot 3} = a^{-51} = \frac1{a^{51}}[/tex]
At this point you just have to choose - or check with your book/teacher if you prefer a negative exponent, or a fraction.

Answer:
Step-by-step explanation:
The vertex is at x=0, so you can eliminate c and d.
To check if its a or b, you can notice that since it opens down, the coefficient of |x| must be negative, making it a.
Two different families bought general admission tickets for a Reno Aces baseball game.
One family paid $70 for 6 adults and 2 children. The other family paid $59 for 3 adults and
4 children. How much does an adult ticket cost?
Answer:
Family One:
$8x6= $48
$70-$48= $22
$22 ÷ 2 = $11
48+22= 70
Family Two:
$8x3= 24
$11x4= 44
44+24 =68
Family Two is not $59 so A isn't correct
Family One:
$9x6= $54
$70-$54= $16
$16÷2= 8
$54+$16= $70
Family Two:
$9x3=$27
$8x4= $32
$32+$27 =$59
These numbers match up to the ticket prices- therefore the answer is B. Adults tickets = $9

Carrie wants to make pancakes for her family for breakfast. The recipe on the box states that 10 2/3 cups of dry pancake mix are needed to make 24 pancakes. Carrie wants to make half of the recipe to make 12 pancakes. In simplest form, how many cups of dry pancake mix will she need in order to make 12 pancakes?
A
16/3
B
5 2/3
C
5 1/3
D
21 1/3
=======================================================
Explanation:
The box says 10 & 2/3 cups of mix will make 24 pancakes.
Carrie only wants to make half that and only wants 12 pancakes.
So we'll divide the mixed number in half.
This means we divide each piece of the mixed number in half like so
10 divided by 2 = 52/3 divided by 2 = 1/3, which you can think of it like 2/2 = 1 then place that over 3.Overall, the mixed number 10 & 2/3 divides in half to get 5 & 1/3 which is the final answer.
------------
To check the result, notice that
2*5 = 102*(1/3) = 2/3Meaning that doubling 5 & 1/3 lands us on 10 & 2/3.
The answer has been confirmed.

Your cafeteria line requires 8 minutes on the average for each customer to proceed through the line and pay the cashier. The average time space between each customer is 30 seconds. If the line is open for 14 hours for lunch, how many customers can you serve for lunch?
Answer:
99 customers.
Step-by-step explanation:
Ok so
14 hours = 840 minutes
Each customer requires 8 and a half minutes
8 minutes (to proceed through the line)
and
30 seconds (the interval time in between to get to another customer)
840 minutes ÷ 8.5 = 98.8..
Therefore, you can approximately serve 99 customers in 14 hours.
I didn't simply round that up, but the last customer does not need the 30 seconds of interval so therefore, you would get to serve 99 customers in 14 hours anyway.

Use the substitution method to solve the following system of equations:
3x + 5y = 3
x + 2y = 0
Answer:
[tex]\displaystyle [6, -3][/tex]
Step-by-step explanation:
To begin this process, we will first select the second equation. Here is how the Substitution method wourks:
[tex]\displaystyle \left \{ {{3x + 5y = 3} \atop {x + 2y = 0}} \right. \\ \\ \\ \left \{ {{y = 2x + 3} \atop {x = -2y}} \right. \\ \\ 3[-2y] + 5y = 3 \hookrightarrow -6y + 5y = 3 \hookrightarrow -y = 3; -3 = y, 6 = x \\ \\ \\ \boxed{[6, -3]}[/tex]
So, you substitute [tex]\displaystyle x[/tex]for [tex]\displaystyle -2y[/tex]and continue combining like-terms until you receive the y-value. You then plug this back into the system to get the x-value, which was what you saw.
