Answer:

-1 and -5

Step-by-step explanation:

-1x-5= 5

-1+-5= -6

The slope of a line perpendicular to the line whose equation is x - 2y = -8 is -2.

In Mathematics and Geometry, perpendicular lines are two (2) lines that intersect or meet each other at an angle of 90° (right angles).

From the information provided above, the slope for the equation of line m is given  by:

x - 2y = -8

2y = x + 8

y = x/2 + 4

slope (m) of line m = 1/2

In Mathematics and Geometry, a condition that is true for two lines to be perpendicular is given by:

m₁ × m₂ = -1

1/2 × m₂ = -1

m₂ = -2

Slope, m₂ of perpendicular line = -2

Answer:

Richard travels 9 meters in 1 second on the zipline.

The slope of the line is 6, which means that Richard travels 6 meters per second on the zip line. Therefore, in 1 second, he would travel 6 meters.

What is the slope?

The slope of a line is a measure of its steepness. Mathematically, the slope is calculated as "rise over run" (change in y divided by change in x).

To find out how far Richard travels on the zip line in 1 second, we can use the information provided in the coordinate plane.

From the graph, we can see that the distance Richard travels increases by 6 meters every second. This means that his speed is constant, and we can calculate it by finding the slope of the line that connects any two points on the graph.

Let's choose the points (2,6) and (3,12) to find the slope:

slope = (change in y)/(change in x) = (12-6)/(3-2) = 6

Hence, the slope of the line is 6, which means that Richard travels 6 meters per second on the zip line. Therefore, in 1 second, he would travel 6 meters.

The matching expressions are:

\(i) 3a x 4 = C (12a)\\ii) a^2 x a = A (a^3)\\iii) 6 × 1/2 a^2 = D (3a^2)\)

i) 3a x 4 can be represented as C (12a) since multiplying 3a by 4 gives 12a.

ii) a^2 x a can be represented as A (a^3) since multiplying a^2 by a gives a^3.

iii) \(6 \times 1/2 a^2\) can be represented as D (3a^2) since multiplying 6 by 1/2 and then by a^2 gives 3a^2.

To understand the matching expressions, let's break down each one:

i) 3a x 4:

This expression represents multiplying a variable, 'a', by a constant, 4. The result is 12a, which matches with C (12a).

ii) a^2 x a:

This expression represents multiplying the square of a variable, 'a', by 'a' itself. This results in a^3, which matches with A (a^3).

iii) 6 × 1/2 a^2:

This expression involves multiplying a constant, 6, by a fraction, 1/2, and then multiplying it by the square of 'a', a^2. The final result is 3a^2, which matches with D (3a^2).

Therefore, the matching expressions are:

i) 3a x 4 = C (12a)

ii) a^2 x a = A (a^3)

iii) 6 × 1/2 a^2 = D (3a^2)

Answer:

d. accuracy

Step-by-step explanation:

In measurements, accuracy is a term that is used to describe the closeness of a measured value to the actual or true value. While precision describes how close different measured values are to each other.

Thus when a measured value is accurate, it implies that the value is very close or almost equal to the true value. The correct answer to the question is  is option D.

Answer:

y = 3. last option is correct answer for 2nd question.

Step-by-step explanation:

f(x) just means y.

horizontal asymptote is y = 'something.'

the graph crosses y = 4, so y = 4 cannot be asymptote.

y = 3 is since the graph never quite touches it.

as for ∞, we see that as x approaches -∞, y almost reaches 3. but not quite. also, as x approaches +∞, y approaches +∞.

so the last option is the correct answer.

The probability that a student who attends the first session also attends the second session is 1/3

Evaluating the probability

We can approach this problem by using conditional probability.

Let's use the notation "S1" to represent the event that a student attends the first session, and "S2" to represent the event that a student attends the second session.

Then we can use the formula for conditional probability:

P(S2 | S1) = P(S1 and S2) / P(S1)

We know that P(S1) = 0.6, since 60% of students attend the first session. We also know that P(S1 and S2) = 0.2, since 20% of students attend both sessions.

So we can plug in these values and solve for P(S2 | S1):

P(S2 | S1) = 0.2 / 0.6

P(S2 | S1) = 1/3

Therefore, the probability that a student who attends is 1/3 or approximately 0.333.

Answer:

Slope = 1/3

Y-intercept = 0

Step-by-step explanation:

Hello!

Slope - Intercept Form: y = mx + b

The slope is the coefficient before the x-variable. Which means that the slope would be 1/3.

The y-intercept is the constant term after the x-term. In this case, there is no term, so the y-intercept is 0.

Answer:

Slope: 1/3

y-intercept: 0

Step-by-step explanation:

y=mx+b

the coefficient (m) of x is always the slope, so therefore the slope is 1/3

the y-intercept (b) is not here in this equation, so the y-intercept is 0

In Mathematics and Geometry, a perpendicular bisector is a line, segment, or ray that bisects or divides a line segment exactly into two (2) equal halves and forms an angle that has a magnitude of 90 degrees at the point of intersection.

This ultimately implies that, a perpendicular bisector bisects a line segment exactly into two (2) equal halves, in order to form a right angle that has a magnitude of 90 degrees at the point of intersection.
