What does it mean for angles to be supplementary and complementary?
Answer:
A complementary angle is an angle that adds up to 90 degrees. supplementary angles add up to 180 degrees. So a supplementary angle lies on a single, straight line, and a complementary angle is a right angle.
Step-by-step explanation:
hopes this helps
Answer:
Step-by-step explanation:
Supplementary is when all the angles add up to 180. Complementary is when all the angles add up to 90.

Karen used a birthday check her mother gave her to start a savings account. She plans to save $25 per
month as well. After 8 months, Karen has $250. Write and solve a linear equation to find the original check
amount from Karen's mother.
Answer:
Explanation:
Lets just say the amount her mom gave her is c
and the months is a
the equation would be
c + 25a = 250
we can plug in 8 for a, cause we know its been 8 months,
c + 25(8)= 250
then do the parentheses
c + 200 = 250
subtract the 200 to isolate the variable c
c = 50
then you get c = 50,
Karen's mom gave her a check for $50.
(why karen btw. i would never give $50 to a karen)
The linear equation to calculate the amount from Karen's mother is
A + 25x = 250
where A is the amount and x is the number of months
The amount from Karen's mother is $ 50
What is an Equation?
Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.
It demonstrates the equality of the relationship between the expressions printed on the left and right sides.
Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.
Given data ,
Let the amount given to Karen by her mother be = A
Let the total number of months be = x
The value of x is = 8 months
The total amount Karen has after 8 months = $ 250
The amount Karen saves per month = $ 25
Now , the equation will be
Total amount Karen has after 8 months = amount given to Karen by her mother + ( amount Karen saves per month x total number of months )
Substituting the values in the equation , we get
250 = A + 25x
On simplifying the equation , we get
A + 25x = 250
when x = 8
A + 25 ( 8 ) = 250
A + 200 = 250
Subtracting 200 on both sides of the equation , we get
A = $ 50
Therefore , the value of A is $ 50
Hence , The linear equation to calculate the amount from Karen's mother is A + 25x = 250
where A is the amount and x is the number of months
The amount from Karen's mother is $ 50

Options 1 and 4 are the only other parallel lines
Step-by-step explanation:
Plug the equation into a graphing calculator and observe your results.
Answer:
The answers are y = −4x, 16x + 4y = 9, and y = −4x + 15
Step-by-step explanation:
y=-4x has the -4 as slope so it parallel
y = −4x + 15 also has the -4 as a slope so it parallel
16x + 4y = 9 u have to solve.
4y=-16x+9 First step is to subtract -16 both sides (which just tosses -16 to the other side where the 9 is.

The point A has coordinates (-1, 6) and the point B has coordinates (7, 2).
i Find the equation of the perpendicular bisector of AB, giving your answer in the form y = mx + c.
ii A point C on the perpendicular bisector has coordinates (p, q). The distance OC is 2 units, where O is
the origin. Write down two equations involving p and q and hence find the coordinates of the possible
positions of C.
Answer:
a) y = 2x -2
b) Equation: q = 2p - 2 ----(1)
p² + q² = 4 ----(2)
The coordinates of C may be (0, -2) or (6/5, 8/5)
Step-by-step explanation:
a) Step 1: Find the coordinates of midpoint, P of AB
x-co-ordinate of P = (x₁ + x₂)/2 = (-1 + 7)/2 = 3
y- co-ordinate of P = (y₁ + y₂)/2 = (6 + 2)/2 = 4
Step 2: Determine the gradient, m₂ of perpendicular bisector of AB
For perpendicular lines, m₁ * m₂ = -1 where m₁ is slope of AB
m₁ = (2 - 6)/(7 - -1) = -4/8 = -1/2
-1/2 * m₂ = -1
m₂ = 2
Step 3: Deriving the equation of the perpendicular bisector in the form y = mx + c
y - y₁ = m(x - x₁); substituting the values of the midpoints of the line
y - 4 = 2(x - 3)
y - 4 = 2x - 6
y = 2x -2
b) Step 1: Derive the values of the p and using the formula of distance between two points:
y = 2x - 2
therefore q = 2p - 2 ----(1)
OC = √(x₂ -x₁)² + (y₂ - y₁)²
2 = √(p - 0)² + ( q - 0)²
2 = √p² + q²
squaring both sides
p² + q² = 4 ----(2)
Substituting (1) in (2)
p² + (2p - 2)² = 4
p² + 4p² - 8p + 4 = 4
5p² - 8p = 0
p(5p - 8) = 0
Therefore p = 0 or 5p - 8 = 0
p = 0 or p = 8/5
Substituting p = 0 in (1)
q = -2
substituting p = 8/5 in (1)
q = 2(8/5) - 2
q = 16/5 - 2
q = 6/5
Hence the coordinates of C may be (0, -2) or (6/5, 8/5)
