Answer:
J' (3, 2)
Step-by-step explanation:
when a point is rotated 90 degrees clockwise, the point goes from (x, y) to (y, -x). You can imagine this rule or come up with it by doing a rotation on a graph, but really it's just a rule you should memorize.
So, apply (x, y) --> (y, -x) to this point:
(-2, 3) --> (3, 2)

7) -129 = 7(-7 - 4v) + 8v
Answer:
v = 4
Step-by-step explanation:
-129 = 7(-7 -4v) + 8v
-129 = -49 - 28v + 8v
-129+49=-20v
-20v = -80
20v = 80
v = 4
Answer:
v=4
Step-by-step explanation:
1) distribute
-129= -49 - 28v + 8v
2) Add like terms
-129= -49 - 20v
3)Isolate
-80= -20v
4)Divide
v=4

Step-by-step explanation:
You are going to plug in the x values to the equation.
f(-4)=-2(-4)-3 -> f(-4)=8-3 -> f(-4)=5
f(-2)=-2(-2)-3 -> f(-2)=4-3 -> f(-2)=1
f(2)=-2(2)-3 -> f(2)=-2-3 -> f(2)=-5
Then you are going to graph. Plot the points on the table (remember rise over run) and connect them with a straight line.

If Sam visits an average of about 1.5 houses per minute for Trick-or-Treating, how many houses could she visit in a half hour? She could visit (your answer) houses
Answer:
45
Step-by-step explanation:
to get the answer you need to multiply 1.5×30
the reason there is 30 is because every hour has 60 minutes in it and a halp of an hour is 30 minutes. So your answer would be 45

Paul is p years old and Susan, s, is five more than two times Paul's age. Which
equation best represents Susan's age?
A S = (5 + 2)p
Bp = 25 + 5
C S = 2p + 5
D p = (5 + 2)s
Net
Answer:
C - S= 2p + 5
Step-by-step explanation:
So this is what we have:
Paul's age : p
Susan's age: s
S is 5 more than two timess of Paul's age meaning that her age is 5 plus 2 of Paul's age thus:
Susan's age = 2p + 5

A man is three times as old as his son.In ten years time their combined ages will be 68 How old is each person
Answer:
22
Step-by-step explanation:
is 22 because 3 times 22 ut maie us 68
Answer:
Let Dad = Y, Son = X
Mathematically, from your statement:
Y = 3X, and (Y+10) + (X+10) = 68
Solving for X in 2nd equation, X = 48-Y
Insert this into first equation and solve for Y:
Y = 3(48-Y)
Y= 144 - 3Y
4Y = 144
Y = 36
Now, solve for X using either equation. I rearranged the 1st equation for X:
X = Y/3
X = 36/3 = 12
The boy is 12 and the dad is 36

Step-by-step explanation:
(58.36)(.75)
43.77
Answer:
$43.77
Step-by-step explanation:
Because 3/4 is just 3 divided by 4, we can divide 58.36 by 4 and multiply that by three.
We get: [tex]\frac{58.36}{4}[/tex]×3, or 14.59×3
From this, we get $43.77

Beth had 1 yard of ribbon. She used 1_ 3 yard for a project. She wants to divide the rest of the ribbon into 1_ 6 yard pieces. How many 1_ 6 yard pieces of ribbon can she make? Explain your solution.
Given:
Total ribbon beth had = 1 yard
Ribbon used for project = [tex]\dfrac{1}{3}[/tex] yard
She wants to divide the rest of the ribbon into [tex]\dfrac{1}{6}[/tex] yard pieces.
To find:
The number of [tex]\dfrac{1}{6}[/tex] yard pieces of ribbon she can make.
Solution:
Total ribbon beth had = 1 yard
Ribbon used for project = [tex]\dfrac{1}{3}[/tex] yard
Remaining ribbon is
[tex]1-\dfrac{1}{3}=\dfrac{2}{3}[/tex]
She wants to divide the rest of the ribbon into [tex]\dfrac{1}{6}[/tex] yard pieces.
Let the number of [tex]\dfrac{1}{6}[/tex] yard pieces of ribbon she can make be x.
[tex]\dfrac{1}{6}x=\dfrac{2}{3}[/tex]
Multiply both sides by 6.
[tex]\dfrac{1}{6}x\times 6=\dfrac{2}{3}\times 6[/tex]
[tex]x=2\times 2[/tex]
[tex]x=4[/tex]
Therefore, number of [tex]\dfrac{1}{6}[/tex] yard pieces of ribbon she can make is 4.

There were 120 entries for the Rogers County Library annual writing competition, and 12 of them were picked to be published. What percent of the entries were picked to be published
Answer:
10%
Step-by-step explanation:
In order to calculate the percentage of the entries that were picked we need to divide the number of picked entries to be published by the total number of entries that were received during the competition like so...
12 / 120 = 0.1
Now we simply multiply this value by 100 in order to turn this into a percentage value
0.1 * 100 = 10%
Therefore, we can now see that only 10% of the total entries were picked to be published.

Max is going to borrow money to buy a TV. For one TV he must pay back $438 in 12 months. For the other TV, he must pay back $555 in 15 months. Which TV has lower monthly payments? Explain how you know
Step-by-step explanation:
"Max is going to borrow money to buy a TV. For one TV he must pay back $438 in 12 months. For the other TV, he must pay back $555 in 15 months. Which TV has lower monthly payments? Explain how you know"
let us solve for the monthly payment expected in both cases
given data
amount= $438
time =12 months
monthly pay = 438/12
monthly pay = $36.5 per month
given data
amount= $555
time =15 months
monthly pay = 555/15
monthly pay = $37 per month
Therefore the First plan which is $438 in 12 months has lower monthly payments because Max will pay $36.5 monthly, the second plan is $0.5 more which is $37

in a survey of 600 adults , 15 % did not know how to ride a bike. how many people can ride a bike? plz I don't really understand this thank u for answering the question SHOW UR WORKING OUT
Answer:
510
Step-by-step explanation:
510 adults can ride a bike out of 600.
We can do this by first taking 15% of 600. To calculate 15% of 600, simply divide the percent (in this case, 15) by 100 and multiply by the number (600). For example, 15 ÷ 100 x 600 = 90, which means the same as 0.15 x 600 = 90.
Now that we know how many adults can't ride a bike, we take 600 and subtract that number from it. So, 600 - 90 = 510, which is how many adults can ride a bike.
Hope this helped! :)
