Answer:
the answer to this should be no solution
Step-by-step explanation:
the first step would be adding seven to both sides, but all that does is leave a zero on the other side, so the equation ends up being 9x=0.
The value of x in the expression is 0.
We have,
Expression: 9x - 7 = -7
To solve for x.
Add 7 on both sides.
9x - 7 + 7 = -7 + 7
9x = 0
x = 0
Thus,
The value of x in the expression is 0.

What is an arc of the circle?A circle's arc is defined as a portion or segment of its circumference. A chord of a circle is a straight line that can be created by connecting the two ends of an arc. A semicircular arc is one whose length is exactly half that of a circle.
Given that the minor arc is 144. The value of angle x will be calculated by the ratio of the difference between the major arc and the minor arc to the 2.
The angle x will be calculated as,
x = ( Major arc - Minor arc) / 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
Answers
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 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)

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?
Answers
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.

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
