Solve the system of equations
Y = 2x
X - Y = 10
Answer:
x=-10, y=-20
Step-by-step explanation:
first you substiture the y in the second equation with the first
x-2x=10
then solve
1x-2x=-1
-x=10
multiply both sides by a negative to make the varible a
positive
x=-10
now we substitue the x in the first equation with -10
y=2(-10)
y=-20

Answer:
The graph is not a function.
Step-by-step explanation:
Using the "vertical line test" to attach a vertical line to each of the points on the graph, we will find that the vertical line that passes through (0,0) has ot one, but two points on it. Remember, if the vertical line passes through more than one points, the graph is not a function. As we know, the vertical line passes through two points, those being (0, -4) and (0, -3). So, we can conclude that the graph is not a function.

The price of a house is originally listed at $110,000. The owners are having a hard time selling it and decide to reduce the price to $101,200. What is the percentage decrease of the price of the house?
Answer:
8%
Step-by-step explanation:
110000 - 101200 = 8800 (change)
change/original price X 100
8800/110000 = 0.08
0.08 X 100 = 8
Hester sells televisions. she earns a fixed amount for each television and an additional $30 if the buyer gets an extended warranty. If Hester sells 13 televisions with extended warranties, she earns 13,00. How much is the fixed amount earns for each television?
Using proportions, it is found that the fixed amount that she earns for each television is of $70.
What is a proportion?A proportion is a fraction of a total amount, and the measures are related using a rule of three.
In this problem, she sold 13 televisions with warranty, hence earning a total in bonus of 13 x $30 = $390.
Hence, the sum of the 13 fixed amounts is of 1300 - 390 = 910, hence the fixed amount she earns is given by:
$910/13 = 70.

Which expressions are equivalent to 3(x + 3y + 2x − y )?
3(3x + 2y) and 9x + 6y
3(3x + 4y) and 9x + 12y
3(x + 4y) and 3x + 12y
3(x + 2y) and 3x + 6y
Answer:
3(3x + 2y) and 9x + 6y
Step-by-step explanation:
3(x + 3y + 2x - y)
= 3 (x + 2x) + (3y - y)
= 3 (3x + 2y)
= (3 • 3x) + ( 3 • 2y)
= 9x + 6y

Two friends, Sasha and Maria, are growing out their hair. They plan to cut it off at a certain
point and donate it to a charity that makes wigs for people with cancer. Sasha's hair is
already 10 centimeters long and grows at a constant rate of 3 centimeters per month. Maria's
hair is 36 centimeters and growing at a speed of 1 centimeter per month. If the girls get their
hair cut on a certain day, they will have exactly the same length to donate. How long will that
take? How long will their hair be?
In
months, both girls' hair will be
centimeters long,
Answer:
13 months, 49 cms
Explanation:
For Sasha, multiply 3 and 13 together for the growth per month. You should get 39, then add the 10 cm Sasha already has. The sum is 49.
For Maria, multiply 13 and 1 for the growth per month. You should get 13, then add the 36 Maria already has. The sum is also 49.

Select the solution(s) to the following equation: (3x−2)(x+5)=0 SELECT ALL THAT APPLY
x=3/2
x=5
x=-5
x=2/3
x=-2/3
x=-3/2
Answer:
Step-by-step explanation:
Check by direct substitution. If we begin by checking x = 3/2, we substitute 3/2 for x in (3x - 2)(x + 5), obtaining (9/2 - 2)(3/2 + 5), which is NOT zero. Therefore x = 3/2 is not a solution.
(3*5−2)(5+5)=0 False. x = 5 is not a solution.
(3*[-5]−2)([-5+5)=0 True. x = -5 is a solution
x = 2/3: (3*2/3 - 2)( ) = 0. True x = 2/3 is a solution
x = -2/3: ( )( ) = -17 1/3; so x = -2/3 is not a solution
x = -3/2: ( ) ( ) = -22 3/4; so x = -3/2 is not a soution

IMPORTANT THIGNS TO REMEMBER:
Has 20 lb. dog food!Gives dog 1 3/5 everyday!Find how much eaten after 2 days!Find how much is left!ANSWER:
Dog has eaten 3 1/5 after 2 days!
There is 16 4/5 left in bag!
EXPLANATION:
Since she gives 1 3/5 to her dog everyday and their asking for 2 days you would multiply 1 3/5 × 2 OR add 1 3/5 + 1 3/5
Which would give you 3 1/5
So, the dog has eaten 3 1/5 lb. of dog food in 2 days.
However then, you would subtract 20 lb. - 3 1/5 lb. because there is 20 lb. dog food in all and the dog has eaten 3 1/5 of it. This would give you 16 4/5 lb.
Meaning there is 16 4/5 lb. left in the bag of dog food!

Which of the following two-dimensional shapes can be rotated to create a sphere?
A. Triangle
B. Square
C. Circle
D. Ellipse
please give an explanation and not just a letter or answer. Thank you.
The shape that can be rotated to create a sphere is the circle (option C).
A sphere is a three-dimensional object with all points equidistant from its center. When a circle is rotated about its center axis, it creates a three-dimensional shape that perfectly matches the definition of a sphere.
Let's consider the other options and why they cannot be rotated to form a sphere:
A. Triangle: A triangle is a two-dimensional shape with straight sides. Rotating a triangle around any axis would not result in a three-dimensional shape with all points equidistant from its center, which is the defining characteristic of a sphere.
B. Square: Similarly, a square is a two-dimensional shape with straight sides. Rotating a square around any axis would not create a sphere, as it would still retain its flat, planar nature.
D. Ellipse: An ellipse is a two-dimensional shape resembling a squashed or stretched circle. Rotating an ellipse would not result in a sphere, as it would still retain its elliptical shape.
Therefore, the shape that can be rotated to create a sphere is the circle (option C) due to its symmetrical and curved nature.
