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
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.
Hope this helps!

Write the slope intercept form of the equation of each line
Answer:
The slope is 1/4 so the slope intercept form is y=1/4+3
Step-by-step explanation:
To find the slope the easiest way from looking at a graph is just to find the rise over run. From looking at the graph we can see that the next point from 0,3 is 4,4. The y here is increased by 1, which means the rise is 1. The x is increased by 4 so the run is 4. From putting rise (1) over run (4) the slope is 1/4. The formula for slope intercept is y=mx+b. m is slope so we substitue that for 1/4 so now we have y=1/4x+b. Then the b is the y intercept, or, at what point the line crosses the y line. Which in this case is 0,3 so the y intercept would be 3 because that is what height it crosses the y line.

Megan has a bag with 8 red cubes, 3 yellow cubes, and 5 green cubes. What is the probability she will pick a red cube, keep it, and then pick another red cube?
Answer:
1st time: 50% chance or 8/16 chance
2nd time: 46% chance or 7/15
I can try again if its wrong
Answer:
7/30
Step-by-step explanation:
8/16 that she picks a red cube.
7/15 that she picks another red cube after keeping the first red cube.
multiply 8/16 (1/2) times 7/15 to get 7/30 as your final answer

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

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.

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.
