Answer:
-2 and 18
Step-by-step explanation:
a + b = 16
ab = -36
a = (16-b)
b(16-b) = -36
16b - b² = -36
-b² + 16b + 36 = 0
b² - 16b - 36 = 0
(b+18)(b-2) = 0
Does anyone know how to do this? Im supposed to find the angle in bold and explain how i got my answer but im not sure how lol.
Answer:
10 degrees
Step-by-step explanation:
5x + 10 = 6x (because corresponding angles are equal)
6x = 10
x = 10/6
x = 5/3
6 x 5/3 = 10 degrees
Use the figure to find the value of X?
Answer:
x=7
Step-by-step explanation:
set it equal to 90 because of vertical angles and solve

1Determine whether the survey sample is biased or unbiased. Explain your answers.
What is your favorite sport? Sample is chosen from people attending a soccer game.
2What is your favorite soft drink? Sample is chosen by picking names out of a telephone book.
4Should more money be put into athletic programs or music programs at school? Sample is chosen from students in the band program.
5What is your favorite vacation destination? Sample is chosen by asking every student in the class.
Answer:
1 is biased, 2 isn't, 3 is biased, 4 isnt
Step-by-step explanation:
If you ask a question to people in a group who are already clearly for a certain topic then it is biased. For survey to not be biased, the people need to be chosen at random. Ask students what their favorite class is, or ask flight attendants where their favorite destination to travel to is. Dont use a group who has any relation to the survey at hand. Asking band students about funding for band is biased, as well as asking people who are at a SOCCER GAME what their favorite sport is.

The front of a sculpture is symmetric about the y-axis. Point A is located at (−3, 0), and AC is the longest side of △ ABC. The perimeter of △ABC is 16. What is the value of a?
Answer:
1124
Step-by-step explanation:

The area of the triangle △ABC is 12 square units.
The question is incomplete. The actual question is
Triangle ABC is symmetric about the y-axis. Point A is located at (-3,0), and AB is the longest side of ABC. If the perimeter of ABC is 16, what is the area?
What is symmetry?Symmetrical forms or figures are things that can have a line drawn through them so that the representations on both sides of the line mirror each other.
How to solve the problem?As could be seen in the figure the triangle △ABC is symmetric along the y-axis. Hence, the side AC and BC must be of the same length let us call it 'a'. Also, the coordinate of B must be (3,0) because (3,0) is the reflection of (-3,0) corresponding to the y-axis.
And, the length of AB=6 units because the distance between (-3,0) and (3,0) is 6 units.
Now, the perimeter of the triangle is 16 units. Therefore,
2a+6=16
⇒a=(16-6)/2
⇒a=5 units.
Hence, we have an isosceles triangle △ABC we can find the height 'h' of the triangle using the Pythagoras theorem. Consider the triangle △ACE
then we have that
the height of the right triangle △ACE= h
the base of the right triangle △ACE= 3 units
the hypotenuse of the right triangle △ACE= a = 5 units.
Hence, by Pythagoras' theorem
h²+3²=5²
⇒h²=25-9=16
⇒h=4 (we choose the positive value of h because length is always positive)
Hence, the area of the triangle △ABC is
(1/2)×base×height
=(1/2)×AB×CE
=(1/2)×6×4 unit²
=12 unit²
Hence, the area of the triangle △ABC is 12 square units.

(7x-26) (5x-27) (10x-23)
Answer:
-547
Step-by-step explanation:
(7×-26) = -182
(5×-27) = -135
(10×-23) = -230
-182+ - 135 + -230
= -317 + -230
= -547
Paul was thinking of a number. Paul adds 10, then divides by 2 to get an answer of -13. What was the original number?
Answer:
I believe its -36
Step-by-step explanation:
-36+10=-26
-26/2= -13
Answer:
-36
Step-by-step explanation:
(x+10)/2 = -13
-13 times 2= -26
-26-10= -36
check
-36+10= -26
-26/2= -13

Melanie is going to a book sale. All the books are priced for $2 each, including sales tax. She can spend no more than $15. Which inequality represents the number of books Melanie can buy?
Answer:
x ≤ 7
Step-by-step explanation:
Let the cost of each book be $2
Let the amount of book she can buy be x
If she can spend no more than $15
Amount of book she can buy≤ Total amount/cost of each book
Amount of book she can buy ≤ $15/$2
Amount of book she can buy ≤ 7.5
x ≤ 7.5 OR x ≤ 7
Hence the required inequality is x ≤ 7. Less than or equal to was used since she can't spend more than $15
Answer:
x ≤ 7
