Answer:
Step-by-step explanation:
first, you have to find the equation of the perpendicular bisector of this given line.
to do that, you need the slope of the perpendicular line and one point.
Step 1: find the slope of the given line segment. We have the two end points (10, 15) and (-20, 5), so the slope is m=(15-5)/(10-(-20))=1/3
the slope of the perpendicular line is the negative reciprocal of the slope of the given line, m=-3/1=-3
step 2: find the middle point: x=(-20+10)/2=-5, y=(15+5)/2=10 (-5, 10)
so the equation of the perpendicular line in point-slope form is (y-10)=-3(x+5)
now plug in all the given coordinates to the equation to see which pair fits:
(-8, 19): 19-10=9, -3(-8+5)=9, so yes, (-8, 19) is on the perpendicular line.
try the other pairs, you will find that (1,-8) and (-5, 10) fit the equation too. (-5,10) happens to be the midpoint.
Answer:
It's A, B, and D.
Explanation:
A-(−8, 19)
B-(1, −8)
D-(−5, 10)

Can someone please how to do fractions in the lowest terms
Answer:
In order to out a fraction in lowest terms, you must divide by the Greatest Common Factor, or GCM, of the numerator and denominator in the fraction. Let's say we have the fraction 25/100. We know that the greastest common factor of 25 and 100 is 25, as 25 ÷ 25 = 1 and 100 ÷ 25 = 4 so 25/100 in lowest terms is 1/4:
25 25 1
___ ÷ ___ = ___
100 25 4
If the GCM of a fraction equals 1, the fraction is simplified. Because the only common factor of 1 and 4 is 1, we know this fraction is simplified.
1 1 1
__ ÷ ___ = ___
4 1 4

An equivalent expression for 16x − 8
Answer:
2x-1
Step-by-step explanation:
Find the measure of each numbered angle
The measure of each numbered angles are ∠1 = 56°, ∠2 = 56° and ∠3 = 74°.
What is Angle?An angle for any figure is formed by two rays which joins at a common point called vertex or node.
Usually angles are measured in degrees or radians.
Consider triangle PMQ
The sum of the interior angles of a triangle is 180°.
∠MPQ + ∠QMP + ∠PQM = 180°
58° + 66° + ∠1 = 180°
∠1 = 180° - (58° + 66°)
∠1 = 180° - 124°
∠1 = 56°
Now, ∠1 and ∠2 are vertically opposite angles. Hence they are equal.
∠2 = 56°.
Again, for triangle NQO
∠2 + ∠3 + 50° = 180°
56° + ∠3 + 50° = 180°
∠3 = 180° - (50° + 56°)
∠3 = 180° - 106°
∠3 = 74°
Hence ∠1, ∠2 and ∠3 are 56°, 56° and 74° respectively.

Please help me answer question 12
Answer:
x = 81, y = 68, z = 99
Step-by-step explanation:
The sum of the 3 angles in a triangle = 180°
Consider the triangle on the left, then
x = 180 - (36 + 63) = 180 - 99 = 81
The exterior angle of a triangle is equal to the sum of the 2 opposite interior angles.
x is an exterior angle of the triangle on the right, thus
13 + y = x , that is
13 + y = 81 ( subtract 13 from both sides )
y = 68
Consider the triangle on the right
z = 180 - (13 + y) = 180 - (13 + 68) = 180 - 81 = 99
2x + 4y-31=123 what is the equation for x and then y
Answer:
i would say
y = ( 77 - x ) / 2
Step-by-step explanation:
2x + 4y = 123 + 31
2x +4y = 154
4y = 154 -2x
y = ( 154 - 2x ) / 4
y = ( 77 - x ) / 2
The number of cookies Natalie can bake varies directly with the time she
spends baking. She can make 3 dozen cookies in 0.5 of an hour. How many
dozen cookies can she make in 5 hours?
Please help fast!!
We already know that 0.5 of an hour, or half of an hour, is 30 minutes. We also know that 3 dozen equals 36. With this information, we can conclude that Natalie can make 72 cookies in one hour. 72 times 5 is 360. 360 divided by 12 is 30, so, Natalie can bake 30 dozen, or 360, cookies in five hours.

The perimeter of a square is 8x +2 units. What is the length of one side? Explain your answer .
Answer: 2x + 0.5 unit
Step-by-step explanation:
A square has 4 equal sides. Therefore, its perimeter is calculated by adding the four sides.
Since the perimeter of a square is 8x +2 units, to get the length of one side, we divide the perimeter by 4. This will be:
= (8x + 2)/4
= 2x + 0.5
Therefore, the length of one side is 2x + 0.5 unit

Kerry is looking foward to a skiing trip this weekend she checked the tempature yesterday and today, and overnigjt is dropped from 12 F to -5 F what is the total difference in the tempature
Answer:
-[tex]17^\circ F[/tex]
OR
[tex]17^\circ F[/tex] decrease in the temperature.
Step-by-step explanation:
Given that:
Temperature at the night = [tex]12^\circ F[/tex]
Temperature in the morning = -[tex]5^\circ F[/tex]
To find:
The total difference in the temperature = ?
Solution:
Difference of any quantity is given by the Final value of quantity minus Initial value of quantity.
Therefore, the difference is given as : -[tex]5^\circ F[/tex] - [tex]12^\circ F[/tex] = -[tex]17^\circ F[/tex]
Negative value in the difference indicates that there is a decrease of the quantity.
So, the answer is:
-[tex]17^\circ F[/tex]
OR
there is decrease of [tex]17^\circ F[/tex] in the temperature.

Answer:
100 because you cal look at the balz on that
Step-by-step explanation:
The measure of exterior angle ∠CAD of a triangle ABC is 100°.
From the given figure, ∠ACB=80° and ∠ABC=20°.
What is an exterior angle theorem?The exterior angle theorem states that the measure of an exterior angle is equal to the sum of the measures of the two remote interior angles of the triangle.
From the given triangle,
m∠CAD=m∠ACB+m∠ABC
⇒ m∠CAD=80°+20°
⇒ m∠CAD=100°
Therefore, the measure of exterior angle ∠CAD of a triangle ABC is 100°.

Andrea has a balance of $135.68 in her savings account. Every Friday Andrea goes to the bank to deposit $170.50 and withdraw (take out) $60. If she does this every Friday for 4 weeks, how much money does Andrea have in the bank? Show all work or explain how you got your answer.
Answer
577.68
Step-by-step explanation:
first you subtract 60 from 170.50 to get 110.5. After that you multiply by 4 to get 442. take 442 and add it to 135.68 to get 577.68. so it would look like this
170.500-60=110.5 110.5 x 4=442 442+135.68=577.68
