Vertical Line Test - Tells us if a graph is a functionVertical Lines - slopes are undefinedStep-by-step explanation:
If the slope m was equal to 0, then it would be a horizontal line rather than a vertical line.
Using the Vertical Line Test, we also know that the graph is not a function.
Usually a vertical line has an undefined slope, as x equals a certain number, and m = unknown.
Answer: It's undefined, because it's vertical

Evaluate 4 cubed. I will mark brainlest.
Answers
4 * 4 * 4 = 16 * 4 = 64
Therefore 4 cubed is 64
Answer:
64
Step-by-step explanation:
4 cubed is 64 because 4 cubed can be written as an exponentiation, where the base is 4 and the exponent is 3, like this: 43. For future reference, note that cubed means that the exponent is 3 regardless of what the base is. When the exponent is 3 (aka cubed) and the base is 4 you simply multiply 4 by 4 by 4 to get the answer 64
Polygon MNP shown on the coordinate planeA dilation centered about the origin will be performed on the polygon with vertices M(- 18, 12) forall(8,10),8(-6,8) and Q(- 8, - 8)
Answers
Answer:
N'(4, 5)
Step-by-step explanation:
The correct question is attached.
Transformation is the movement of a point from its initial location to a new location. Types of transformation are reflection, rotation, dilation and translation.
Dilation is a transformation that changes the size of a figure (i.e. it increases or reduces the size).
If a point A(x, y) is dilated by a factor k, the new point is at A'(kx, ky).
The location of the polygon vertex is at M(-16, 12), N(8, 10), P(-6, 8) and Q(-8, -8).
After dilation, the new location of M is at M'(-8, 6)
M(-16, 12) ⇒ M'(-8, 6)
M(-16, 12) ⇒ M'[1/2(-16), 1/2(12)]
Hence the dilation factor is 1/2. This means that the new vertex is at:
N'(4, 5), P'(-3, 4) and Q'(-4, -4).

ABCD is a quadrilateral inscribed in the circle
=> ∠ABD = ∠ACD
⇔ x = 34°
and ∠ADB = ∠ACB
we also have:
∠DCE + ∠ DCB = 180°
⇔ 96° + x + ∠ACB = 180°
⇔ ∠ACB = 180 - 96 - x = 180 - 96 - 34 = 50
because ∠ADB = ∠ACB => y = 50°
Step-by-step explanation:
Alexus is modeling the growth of bacteria for an experiment in science. She assumes that there are B bacteria in a Petri dish at 12:00 noon. In reality, each bacterium in the Petri dish subdivides into two new bacteria approximately every 20 minutes. However, for the purposes of the model, Alexus assumes that each bacterium subdivides into two new bacteria exactly every 20 minutes.
2a. Create a table that shows the total number of bacteria in the Petri dish at 1/3 hour intervals for 2 hours starting with time 0 to represent 12:00 noon.
2b. Write an equation that describes the relationship between total number of bacteria T and time h in hours, assuming there are B bacteria in the Petri dish at h=0.
2c.If Alexus starts with 100 bacteria in the Petri dish, draw a graph that displays the total number of bacteria with respect to time from 12:00 noon (h=0) to 4:00 p.m. (h=4). Label points on your graph at time h=0,1,2,3,4.
2d. For her experiment, Alexus plans to add an anti-bacterial chemical to the Petri dish at 4:00 p.m. that is supposed to kill 99.9% of the bacteria instantaneously. If she started with 100 bacteria at 12:00 noon, how many live bacteria might Alexus expect to find in the Petri dish right after she adds the anti-bacterial chemical?

Which of the following is a solution to the system? Show your work.
3x+2y=-3
3x-y=6
Group of answer choices
(-1, 0)
(1, -3)
(2, 0)
LaTeX: (0,-\frac{3}{2})
Answers
Answer:
(1, -3) is a solution to the system of equations ⇒ B
Step-by-step explanation:
Let us solve the system of equations
∵ 3x + 2y = -3 ⇒ (1)
∵ 3x - y = 6 ⇒ (2)
→ Subtract equation (2) from equation (1)
∵ (3x - 3x) + (2y - -y) = (-3 - 6)
∴ (0) + (2y + y) = (-9)
∴ 3y = -9
→ Divide both sides by 3 to find y
∴ y = -3
→ Substitute the value of y in equation (2) to find x
∵ 3x - (-3) = 6
∴ 3x + 3 = 6
→ Subtract 3 from both sides
∵ 3x + 3 - 3 = 6 - 3
∴ 3x = 3
→ Divide both sides by 3 to find x
∴ x = 1
To check the answer substitute the values of x any in each equation if the two sides of the equation are equal, then the solution is right
∵ 3x + 2y = -3
∵ 3(1) + 2(-3) = -3
∴ 3 - 6 = -3
∴ -3 = -3
→ The two sides of the equation are equal
∵ 3x - y = 6
∵ 3(1) - (-3) = 6
∴ 3 + 3 = 6
∴ 6 = 6
→ The two sides of the equation are equal
∴ The solution satisfies the two equations
∴ (1, -3) is a solution to the system
