Answer:
The slope of a line that is perpendicular to the given line is 
Step-by-step explanation:
The equation of the line in Slope-Intercept form is:

Where "m" is the slope of the line and "b" is the y-intercept.
Solve for "y" from the equation of the line
:

You can observe that the slope of this line is:

By definition, the slopes of perpendicular lines are negative reciprocal, then, the slope of a line that is perpendicular to the give line, is

Answer:
The generalisation she can make from her work is that the other two angles of the quadrilateral are supplementary i.e their sum is 180°
Step-by-step explanation:
We are given the following from what she knows
m∠3=2⋅m∠1... 1
m∠2=2⋅m∠4 ... 2
m∠2+m∠3=360 ... 3
From what is given, we can substitute equation 1 and 2 into equation 3 as shown:
From 3:
m∠2+m∠3=360
Substituting 1 and 2 we will have:
2⋅m∠4 + 2⋅m∠1 = 360
Factor out 2 from the left hand side of the equation
2(m∠4+m∠1) = 360
Divide both sides by 2
2(m∠4+m∠1)/2 = 360/2
m∠4+m∠1 = 180°
Since the sum of two supplementary angles is 180°, hence the generalisation she can make from her work is that the other two angles of the quadrilateral are supplementary i.e their sum is 180°

Answer:
$0.50/lb
Step-by-step explanation:
The increase in cost is $40-25 = $15 for an increase in weight of 50-20 = 30 lb. That makes the cost per pound be ...
cost/pounds = $15/(30 lb) = $0.50/lb
Answer:
1) Repaid for the loan = $239,511.60
2) Percentage = 58.2%
3) Average amount = $387.53
Step-by-step explanation:
Given :
Amount $100,000
Rate 7%
Payments 360 - $665.31
Total interest $139,511.60
To find :
1) How much will be repaid for this loan?
Repaid for the loan = Amount - Total interest
Repaid for the loan = 100,000 + 139,511.60
Repaid for the loan = $239,511.60
2) What percentage will be repaid for this loan?




3) What will be the average amount per payment for interest?
