A complementary angle is an angle that measures
90 degrees and they are also classified as right angles.
A supplementary angle is an angle that measures 180 degrees.
(i) Since the sum of the measures is 90 degrees, they are complementary.
(ii) Since the sum of their measures is 180 degrees, they are supplementary.
(iii) Since the sum of their measures is not 90 or 180, they are neither.
(iv) Since the sum of their measures is 180 degrees, they are supplementary.
(v) Since the sum of their measures is 180 degrees, they are supplementary.
(vi) Since the sum of their measures is 90, we have complementary.

Write the equation of the line passing through the given point that is perpendicular to the
given line.
12. y = - 4x + 7: (4,2)
Answers
Answer:
The equation of the line passing through the given point that is perpendicular to the given line y = - 4x + 7: (4,2) is [tex]\mathbf{y=\frac{1}{4}x+2 }[/tex]
Step-by-step explanation:
Write the equation of the line passing through the given point that is perpendicular to the given line.
y = - 4x + 7: (4,2)
The equation of required line will be in slope-intercept form [tex]y=mx+b[/tex] where m is slope and b is y-intercept.
We need to find slope and y-intercept
Finding slope:
When two lines are perpendicular their slopes are opposite reciprocal of each other. [tex]m_1=-\frac{1}{m_2}[/tex]
So, slope of given line = -4 ( Comparing with [tex]y=mx+b[/tex] m = -4)
Now, slope of required line will be: m =1/4 (Opposite reciprocal)
Finding y-intercept
y-intercept can be found using m = 1/4 and point (4,2)
[tex]y=mx+b\\2=\frac{1}{4}(4)+b\\2=b[/tex]
So, we get b = 2
Now, Equation of line
Equation of line having slope m = 1/4 and y-intercept b = 2 is:
[tex]y=mx+b\\y=\frac{1}{4}x+2[/tex]
So, the equation of the line passing through the given point that is perpendicular to the given line y = - 4x + 7: (4,2) is [tex]\mathbf{y=\frac{1}{4}x+2 }[/tex]

C. -1 ≤ y ≤ 1
Step-by-step explanation:
The range is the vertical extent of the graph.
Here, the graph goes back and forth between y = -1 and y = +1, so the range is the interval -1 to +1, with those values included. Written as an inequality, it is ...
-1 ≤ y ≤ 1
Written in interval notation, it is ...
[-1, 1] . . . . using square brackets to indicate the end values are included
__
Curly brackets { } are used to delimit a set. That is {-1, 1} means the y-values consist only of -1 or 1 and nothing else. Obviously, that is not the case here.
_____
So, the steps are ...
1) understand the vocabulary, so you know what the question is asking
2) be able to read a graph and identify high points and low points
3) recognize the various ways the answer can be written
4) locate one of those answer possibilities in the list of choices offered

Step-by-step explanation:
sports store sells three different packs of tennis balls. Brand A costs $2.50 for two balls, brand B sells three balls for $3.90, and brand C has a sale of four balls for $5.12. Which inequality about the unit price per ball is correct
Brand A:
$2.50 for 2
Brand B :
$3.90 for 3
Brand C:
$5.12 for 4
We calculate the unit price :
Brand A:
$2.50 / 2 = $1.25
Brand B:
$3.90 / 3 = $1.30
Brand C:
$5.12 / 4 = $1.2
Chris has just sold a home valued at $85,000. Her
normal commission for the homes that she sells
is 8%. Determine the amount that Chris will make
on the sale of the $85,000 home.
Answers
Answer:
Amount of Chris' commission = $6800
Step-by-step explanation:
Given that:
Value of the house sold by Chris = $85,000
Percent of Chris' commission = 8%
Amount of Chris' commission = 8% of 85000
Amount of commission = [tex]\frac{8}{100}*85000[/tex]
Commission = 0.08 * 85000
Commission = $6800
Hence,
Amount of Chris' commission = $6800

[tex]x = \frac{12}{7}\ books[/tex]
Step-by-step explanation:
Given
[tex]3\ books = 1\frac{3}{4}\ weeks[/tex]
Required
Number of books in 1 week
Represent the number of books in 1 week with x.
So, we have:
[tex]3\ books = 1\frac{3}{4}\ weeks[/tex]
[tex]x = 1\ week[/tex]
Cross Multiply
[tex]x * 1\frac{3}{4} = 3 * 1[/tex]
[tex]x * 1\frac{3}{4} = 3[/tex]
Convert fraction to improper fraction
[tex]x * \frac{7}{4} = 3[/tex]
Multiply through by [tex]\frac{4}{7}[/tex]
[tex]x * \frac{7}{4}*\frac{4}{7} = 3 * \frac{4}{7}[/tex]
[tex]x = 3 * \frac{4}{7}[/tex]
[tex]x = \frac{12}{7}\ books[/tex]
Hence: 12/7 books were read in a week

Answers
Answer:
a(y-1)/1+y
Step-by-step explanation:
Given the expression y = a + p/a-p
yo are to make P the subject of the formula:
Step 1: Cross multiply
y = a + p/a-p
y(a-p) = a+p
Step 2: open the bracket
ya - yp = a+ p
Step 3: Collect the like terms
ya - a = p+ yp
ya - a= p(1+y)
a(y-1) = p(1+y)
Step 4: Divide both sides by 1+y
a(y-1)/1+y = p(1+y)/1+y
a(y-1)/1+y = p
p =a(y-1)/1+y
Hence the required solution is p = a(y-1)/1+y

The Reeds are moving across the country. Mr. Reed leaves 5 hours before Mrs. Reed. If he averages 40mph and she averages 50mph, how many hours will it take Mrs. Reed to catch up to Mr. Reed?
Answers
Answer:
It will take 20 hours for Mrs. Reed to catch up with Mr. Reed
Step-by-step explanation:
Given that:
Mr. Reed leaves 5 hours early.
Speed of Mr. Reed = 40 mph
Distance covered in 5 hours = 40 * 5 = 200 miles
Let,
h be the number of hours and D be the total distance.
D = 40h + 200
Speed of Mrs. Reed = 50 mph
D = 50h
For catching up, both distances will be same
D = D
50h = 40h + 200
50h - 40h = 200
10h = 200
Dividing both sides by 10
[tex]\frac{10h}{10}=\frac{200}{10}\\h=20[/tex]
Therefore,
It will take 20 hours for Mrs. Reed to catch up with Mr. Reed

Answer: See step by step
Step-by-step explanation: For A my 15 statements are.
It has 3 triangles inside it, ACD, ADC, and ABCIt has 2 right triangles, and 1 isocelesAC≅ABCD≅DBD is midpoint of CBAD⊥CBAngle CDA=90 degreesAngle BDA equal 90 degreesAD≅ADΔCDA≅ΔBDA by any congruence theorem, (SSS, SSA,AAS,ASA, HL) [tex]AD^{2}[/tex]+ [tex]DB^{2}[/tex]=[tex]AB^{2}[/tex]12.[tex]AD^{2}[/tex]+ [tex]CD^{2}[/tex]= [tex]AC^{2}[/tex]
13. Triangle ABC has a max of 180 degrees.
14. We can rotate this triangle 180 degrees and it will coincide.
15. We can reflect triangle ACD over vertical line ACD and it will be congruent to ABD.
2. We use pythagorean theorem since it has a right angle.
[tex]AD^{2}[/tex]+ [tex]DB^{2}[/tex]=[tex]AB^{2}[/tex] Let plug it in.
[tex]40^{2}[/tex]+[tex]b^{2}[/tex]=[tex]45^{2}[/tex]
1600+ b^2=2025
b^2=424
sqr root of 425 is about 21. Now let find the perimeter.
AB is 45, Since BD+DC=CB, and they are congruent they are equal so 21+21=42 and AC is congruent to AB so it is 45. So the perimeter is 132.
For 3. Start at the orgin, then go up 5 on the y-axis so you should be at (0,5)
Then use the rise over run method to graph it. go left -3 and and up 1. Keep doing that 2 more times then draw a straight line.
Your 3 point should be
(0,5)
(1,2)
(2,1)
