The equation y = x + 3 represents a linear function. Which ordered
pair does not lie on the graph of this function?
A) (-10, -7)
B) (13, 16)
C) (-14, -11)
D) (-20, 17)
Answer:
D) (-20, 17)
Step-by-step explanation:
y = x + 3 (substitute the numbers & check if the equation is still true)
-7 = -10 + 3 -> -7 = -7
16 = 13+3 -> 16 = 16
-11 = -14 + 3 -> -11 = -11
17 = -20 + 3 -> 17 = -17 (not true)
[tex]\sqrt 18- \sqrt 2[/tex]
Answer:
2√2
Step-by-step explanation:
18 factors down to 3 * 3 * 2
The rule for taking the square root of a number factored into primes is if they are in pairs, take one of the pairs out of the root sign and throw the other one away. Any odd number of primes always has one prime left under the root sign.
3√2 - √2
Root 2 is a common factor on either side of the minus sign.
√2*(3 -1)
√2 * 2
Min mows lawns to earn money. The points in this
graph represent the total amount of money Min earns

Of the 650 student at westmoreland junior high, 80% will attend the field trip. How many student will attend the field trip?
Answer:
520 students will attend
Step-by-step explanation: sorry forgot to explain. An easy way to do it is to multiply the number your using (650) x the percentage (80%) here's an example: 60% of 1,005 multiply 60 x 1005 = 603
603 is 60% of 1005. ;D
Answer: 520
Step-by-step explanation: A way to find even percentages (10%, 20%, etc) is to take 10% of the original number, in this case, it would be 65, and then multiply it by the first number in the percentage. In this case, it would be;
65 x 8 = 520
Hope this helps!
REPOST PLEASE I NEED HELP I could really use some help with this guys:)................................................................................................................................................................................................................................................Groundhog's Day is on February 2nd each year. On this day, in Punxsatawney, Pennsylvania, thousands of onlookers watch to see if Phil, the groundhog, will cast a shadow. If he does, then six more weeks of winter are predicted. If he doesn't, then an early spring is predicted. Historically, Phil's prediction has only been correct about 40% of the time.
Using complete sentences, design a simulation to determine the probability that Phil's prediction will be correct at least two out of the next three years. Make sure to explain how you would use the simulation to determine the probability.

Glenn needs to cut pieces of ribbon that are each 1 meter long to make ribbon key chains.
If he has 9 pieces of ribbon that are each 1 dekameter long, how many 1−meter pieces of ribbon can he cut?
9514 1404 393
Answer:
90
Step-by-step explanation:
1 dekameter is 10 meters, so each of Glenn's 9 pieces of ribbon can be cut to make 10 1-meter pieces.
9 × 10 m = 90 m . . . . length of available ribbon
(90 m)/(1 m/piece) = 90 pieces
Glenn can cut 90 1-meter pieces from the ribbon he has.

A jar contains 21 brown and 19 blue marbles. A marble is drawn at random. What is the theoretical probability of drawing a blue marble? P(blue) = 63.3% P(blue) = 47.5% P(blue) = 2.5% P(blue) = 19% P(blue) = 52.5%
Answer:
The answer would be the 1st one.
Step-by-step explanation:
When you use a percentage calculator or look it up, you can shay 40 as a percent of 19 and the answer will be 47.5%. You could also divide and get your answer that way as well.
Hope that helps! If you get it wrong, please tell me so I could check my work. Have a great rest of your day :)!

Your dog is 8 years younger than your friend. In 2 years, your friend will be three times as old as your dog. How old is your dog now?
Answer:
Dog is 2 years old
Step-by-step explanation:
Let dog's age = d
Let friend's age = f
Your dog is 8 years younger than your friend:
d +8 = f
In 2 years, your friend will be three times as old as your dog:
3(d+2) = (f+2)
3d+6 = f+2
3d = f - 4
(sub in f=d+8 from above)
3d = f - 4
3d = d+8 - 4
2d = 4
d = 2

Find the midpoint of the line segment with the given endpoints. please help !!
Answer:
A. [tex] (-3, -2) [/tex]
Step-by-step explanation:
Given:
(4, -10) and (-10, 6)
Required:
Midpoint of the two endpoints
Solution:
Apply the midpoint formula,
[tex] M(\frac{x_1 + x_2}{2}, \frac{y_1 + y_2}{2}) [/tex]
Where,
(4, -10) = (x_1, y_1)
(-10, 6) = (x_2, y_2)
Plug in the values
[tex] M(\frac{4 + (-10)}{2}, \frac{-10 + 6}{2}) [/tex]
[tex] M(\frac{-6}{2}, \frac{-4}{2}) [/tex]

yes because 5 times 4 a
is 20 a and 5 times 7u is 35
Answer:
Yes
Step-by-step explanation:
If you were to give the variables a number value such as a=2 u=3
5(4*2+7*3)=145
20*2+35*3=145
