Answer:
subtract the equations
Step-by-step explanation:
the second answer option is nonsense.
if the equations really have exactly one solution, then it is impossible to make them equal.
if 2 equations can be made equal, that means they have infinitely many solutions.
the other answers have all some merit.
but the last one (subtract the equations) is the best one.
it means
y = 2x + 4
- y = 3x - 6
------------------
0 = -x + 10
after adding x to both sides we get
x = 10
with that we use any of the 2 basic equations to get y :
y = 2x + 4 = 2×10 + 4 = 24
this worked right away, because the y terms have the same coefficients (1). so, by subtracting one equation from the other we eliminate y as variable and can solve for x.
if that was not the case like in
2y = 4x + 8
y = 3x - 6
we would have to do some transformation or manipulation to bring the system into a form like here in the beginning.
and the first and the third answer option would apply.

B.) 201.58 - x = -57.18
C.) -201.58 - x = -57.18
D.) 201.58 - x = 57.18
The equation that can be used to find the amount of bill payments Mike makes, from the $201.58 and the balance in the account of -$57.18, after making the payments is specified in option B.
B.) 201.58 - x = -57.18
What is a mathematical equation?An equation in mathematics is a mathematical statement that joins two expressions, with an 'equals to' mathematics symbol.
The initial amount in Mike's account = $201.58
The money in Mike's account after paying his bills = -$57.18
The amount of Mike's bill payment = x
Therefore;
The initial amount of money in Mike's account less the amount Mike paid as bills = The amount Mike has remaining in his account (his account balance)
Plugging in the values of the variables, we get;
The initial amount = 201.58
The amount of bill payments Mike makes = x
The balance in the account = -57.18
The equation, by plugging in the values becomes:
201.58 - x = -57.18The correct option is therefore, option B

The volume of a sphere is V = 4/3 x pi x r^3 .
What is unitary method ?Area is the total amount of space that an object's shape or a flat (2-D) surface occupy.
Create a square on paper by using a pencil. Tw dimensions make it up. A shape's area on paper is the space it takes up.
Imagine that your square is made up of smaller unit squares.
The area of a figure is equal to the number of unit squares required to completely cover the surface area of a particular 2-D shape. Square cms, square feet, square inches, square meters, etc. are a few common units for measuring area.
To get the area of the square figures presented below, draw unit squares with 1-centimeter sides. Therefore, the shape will be measured.
According to our question-
V' equals (4 pi x r' x r'2) (4 pi x (.9 3) x r2 x r')
This equation expresses how quickly the rind volume changes over time.
As stated in the issue, r' = 2.
Additionally, the radius will be r = 2 * 5 = 10 after 5 weeks.
V' equals (4 pi x 102 x 2) (Pi x (.93) x 10 x 2) = -
V' is equal to (800 pi) - (800 pi x (.729)).
V' = (800 x pi) (1 - .729) (1 - .729)
V' = (800 x pi)(.271) (.271)

A. On the vertical number line, 2 1/2 is located below 2 3/5
B. On the vertical number line, 2
3/5 is located below 2 1/5 C. On the vertical number line, 2 3/5 and 2 1/5 are located at the same point
D. On the vertical number line, 2 1/5 and 2 3/5 are both located
is located below 0
Answer: A.
Step-by-step explanation: On the vertical number line, 2 1/5 is located below 2 3/5.
To compare the values of 2 1/5 and 2 3/5, you need to first convert them to fractions with a common denominator. For example, you can convert 2 1/5 to a fraction with a denominator of 5 by multiplying the numerator (1) and the denominator (5) by 2: 2 1/5 = (2 * 1)/(2 * 5) = 2/10 = 1/5.
Then, you can add the fractions to get a common denominator: 2 1/5 + 2 3/5 = (2 + 2) + (1/5 + 3/5) = 4 + (4/5) = 4 4/5.
Since 4 4/5 is greater than 4, it follows that 2 3/5 is greater than 2 1/5. Therefore, on the vertical number line, 2 3/5 is located above 2 1/5.

The graph of the equation Y = x² and the 5x² + 4 is attached below.
Equation:
Equation is the combination of variables, numbers and constants.
Given,
Here we have to sketch the region enclosed by the given curves for the equations, Y = x² and Y = 5x² + 4.
Here we have to take some sample value for x to find the value of equations.
And then by using the values, we have to plot the graph through this.
x = -2, -2, 0, 1, 2
Then the corresponding value of y is calculated as,
=> x = -1 => y = 1
=> x = -2 => y = 4
=> x = 0 => y = 0
=> x = 1 => y = 1
=> x = 2 => y = 4
Similarly, the value of Y for the next equation is,
=> x = -2 => y = 24
=> x = -1 => y = 9
=> x = 0 => y = 4
=> x = 1 => y = 9
=> x = 2 => y = 24

Considering all the option and the question, We cannot determine anything about the angle is the right answer.
what is angle?An angle is a geometric shape that is formed by two rays that share a common endpoint, called the vertex.
what is vertex?The vertex of an angle is the common endpoint of the two rays that form the angle. The vertex is also sometimes called the "corner" of the angle.
It is not possible to determine whether the angle of the ramp will decrease or increase without more information. The angle of the ramp is determined by the slope of the ramp, which is the change in height divided by the change in distance. If the ramp starts closer to the step, it will have a different slope, and therefore a different angle, than if it starts 5 feet away from the base of the step.

What color is the condensed water, also called condensation, that collects on the inside of the top cup?
When the coloured water evaporates and condenses on the inside of the top cup, there is no colour in the water on the inside surface of the cup.
As water molecules in the air cool, they slow down and combine into tiny droplets of liquid water. This process is called condensation. This happens when water molecules in the air touch the outside of a cold mug exposed to air.
Water vapour in the air is extracted by several techniques, such as cooling the air below the dew point, exposing the air to a desiccant, using membranes that allow only water vapour to pass, collecting the mist, or pressurizing the air. I can do it.
Common examples are water forming on the outside of a cold mug, or moisture forming on a car window on a cool night.
