Answer:
List the factors Count the number of factors Prime number have exactly two factors Composite numbers have two or more factors
Step-by-step explanation:
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.
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
