If a number can only be divided by 1 and itself it is prime, but if it is composite, it can be divided evenly by numbers other than 1 and itself.
63 can be divided by 3 and 21, so it is a composite number.
Answer:
21 = -10m - 3
Add 3 to both sides:
24 = -10m
Divide by -10 on both sides:
-2.4 = m
Answer:
A
Step-by-step explanation:
We can calculate the equation of the lines based on two points. First line m:
y = ax +b
where a is the slope and b is the y-intercept. To find the slope we use the x and y of the points as:
a =
So:
y = 6x + b
we can find the y intercept by substituting the x and y for one of the points:
solving for b:
b=-32-(6)(-4)= -8.
So the equation is:
y = 6x - 8.
We can change it to:
y + 8 = 6x
8 = 6x - y.
So it’s (A).
Hope that helps!
The answer is f(x) = 2.9|x| and f(x) = 1.2|x + 8<span>|</span>
Answer:
<u>about</u> 7 pounds
Step-by-step explanation:
NOTE: 16 ounces equals a pound
so, we would do 15x7 which equals 105 ounces. then we would do 105/16 since 105 is the ounces in total and 16 ounces=1 pound. so our answer would equal to 6.5625. which rounded off would be about 7 pounds. I hope this is correct /helps!:)
