For this case we have that by definition, the GFC (greatest common factor) of two numbers is given by the greater number that is a factor of both numbers. Then, let:
We decompose into factors:
15: 1,3,5,15
18: 1,2,3,6,9,18
The GFC is 3.
So, we have that the GFC of the expressions is:
Answer:
Answer:
k = 2
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
y = - 3x + 5 ← is in slope- intercept form
with slope m = - 3
Parallel lines have equal slopes, thus the 2 points have a slope of - 3
calculate the slope using the slope formula and equate to - 3
m =
with (x₁, y₁ ) = (4, - 1) and (x₂, y₂ ) = (k, 5)
m = =
= - 3 ( multiply both sides by (k - 4) )
- 3(k - 4) = 6 ( divide both sides by - 3 )
k - 4 = - 2 ( add 4 to both sides )
k = 2
Answer:
The symbol is <, because -11.5 < -9.5
Step-by-step explanation:
The number line is arranged from smallest to greatest numbers, and when you read the numbers you start from left to right, so the numbers in the left are smaller than the number in the right
In the set of the negative numbers, the greatest value is the smallest number
Examples
-1 is greater than -2 because -2 lies before -1 on the number line
∵ The numbers are -11.5 and -9.5
∵ The number -11.5 is before the number -9.5 on the number line
- That means -11.5 is smaller than -9.5
∴ -11.5 < - 9.5
∴ The symbol is <
