30 pound in kilograms are 13.61 kilograms
Answer:
slope = -9/2
Explanation:
The form of the slope-intercept equation is:
y = mx + c
where:
m is the slope
c is the y-intercept
The given is:
y = -9/2 x
Comparing the given with the general form, we will find that:
m is the slope = -9/2
c is the y-intercept = 0
Hope this helps :)
y = -9/2
Answer: Last option.
Step-by-step explanation:
Given the equation:
Follow these steps to solve it:
- Subtract the fractions on the left side of the equation:
- Using the Difference of squares formula (
) we can simplify the denominator of the right side of the equation:
- Multiply both sides of the equation by 
and simplify:
- Multiply both sides by 
:
- Apply Distributive property and simplify:
- Divide both sides of the equation by -6:
- Factor the equation and solve for "m":
In order to verify it, you must substitute 
into the equation and solve it:
<em>NO SOLUTION</em>
Answer:
Increased by a factor of 4
Step-by-step explanation:
The original circumference is:
C1 = 2 * pi * r1
The new circumference is:
C2 = (2 * pi * r2)
"circumference that is 4 times larger than the original"
(2 * pi * r2) = 4 (2 * pi * r1)
Rewriting:
r2 = 4r1
Answer:
The radius of the original circle is:
increased by a factor of 4
Hope this helps :)
