Ok I just did a test on this and my teacher taught me how to do it, For problem like number 3 with the table of numbers, You take the first to sets like -1,-5 and 1,1....Then   you do 1 - (-5) =  your answer then 1 - (-1) = your answer than you get 6 and 2  ...you want to divided those numbers 6/2 = 3 and that is positive so #3 is positive.                                                                                                                       Same thing for #4  1,-2 and 2,-6       -6 - (-2) = x      2 - 1 = x  x/x  I want you to solve #4 for yourself        #2 is already done  y = -4x + 5  just take the -4 and -4 is negative so #2 is negative.   Then #1  I have a hard time with those but I think it's positive

Explain how you decide whether a number is a prime number or a composite number

Answers

To determine if  a  number is  prime or  composite, follow these steps.Find  all factors of  the  number.If  the  number has  only tow  factors, 1 and  itself, then it is  prime. If the  number  has there are many possible ways to explain the  solution to this  problem.These are just three if  you make a  mistake, choose a  different  button.

Answer:

List the factors Count the number of factors Prime number have exactly two factors Composite numbers have two or more factors

Olivia has 21 coins in her drawer. Nine of the coins are nickels, and the rest are pennies. What is the total value of the coins in her drawer?

Answers

21 COINS
9 are NICKLES
all the other are pennies
21 - 9 =12
so 12 pennies
1 nickle is 5 cents so
5*9 = 45 cents so
45 + 12 = 57
so the answer is 57 cents 
do 21-9=12. So there are 12 pennies. then since you are finding the value of the coins you do 9*5=45 since there are 9 nickels and each nickel is 5 cents. Then you add 45+12=57. So the value is 57 cents.

How to solve this math question?

Answers

To find the length of side HJ, we need to use sine, as we're looking for the length of the side that is opposite to the side where we have an angle measure.


Sin(70*) = x/13

Sin(70* = 0.94) = x/13

Multiply both sides by 13.

Sin = 12.21 = x

The side HJ is equal to 12.21.

Write an equation of the line that passes through (−4, −9) and is parallel to the line y=4x .

Answers

Answer:

y = 4x + 7

Step-by-step explanation:

parallel = same slope

y = 4x + b

plug in (-4, -9)

-9 = 4(-4) + b

-9 = -16 + b

b = 7

y = 4x + 7

Answer:

7=4x+7

Step-by-step explanation:

To do this you would just plug in (-4,-9) into the equation y=mx+b so we would get -9=4(-4)+b when you simplify you will get -9=-16+b so we would add 16 to both sides and we would get 7=b so we would know that the y intercept is 7 and we know that if a line is parallel to another line is just has a different b so for our equation we would get 7=4x+7
