Answer:
Step-by-step explanation:
step 1
Find the slope of the given line
The formula to calculate the slope between two points is equal to
we have
(-2,5) and (-4,8)
substitute the values in the formula
step 2
Find the slope of the perpendicular line to the given line
we know that
If two lines are perpendicular, then their slopes are opposite reciprocal (the product of their slopes is equal to -1)
so
----> slope of the given line
therefore
---> slope of the perpendicular line to the given line
step 2
Find the equation of the line in point slope form
we have
substitute
step 3
Convert to slope intercept form
isolate the variable y
Answer:
nty
Step-by-step explanation:
The answer is A in my opinion
The least is 2000 and the greatest is 2005 so the difference is 5 because 2000+5=2005 !!! Hope its helpful
Answer:
Problem 1:
Problem 2:
Problem 3:
The radius is cm.
Problem 4:
The width is 15 cm.
Step-by-step explanation:
Problem 1:
We want to solve for .
Multiply both sides by 3:
Rearrange the multiplication using commutative property:
We want to get by itself so divide both sides by what is being multiplied by which is .
Problem 2:
We want to solve for in .
Multiply both sides by 3:
We want by itself so divide both sides by what is being multiply by; that is divide both sides by .
Problem 3:
The circumference formula for a circle is . We are asked to solve for the radius when the circumference is cm.
Divide both sides by what r is being multiply by; that is divide both sides by :
Reduce fraction:
The radius is cm.
Problem 4:
The perimeter of a rectangle is where is the width and is the length.
We are asked to find w, the width, for when L, the length, is 5, and the perimeter is 40.
So we have this equation to solve for w:
Simplify the 2(5) part:
Subtract both sides by 10:
Divide both sides by 2:
Simplify the fraction:
The width is 15 cm.
