Answer:

All you have to do is insert the first value where the x is, and the second value where the y is.

y = 3x + 5

11 = 3(2) + 5

11 = 6 + 5

11 = 11

So, this is right.

Now, let's check (3,13)

y = 3x + 5

13 = 3(3) + 5

13 = 9 + 5

13 = 14

This is NOT true. So, your answer is: Only (2,11)

Hope this helps!

Kim caught a fish that was 9/10 of a meter long. Doug caught a fish that was 2/3 as long as Kim's fish. So, Doug caught a fish that was 3/5 meters long.

<h3>What is the fundamental principle of multiplication?</h3>

If an event can occur in m different ways and if following it, a second event can occur in n different ways, then the two events in succession can occur in m × n different ways

Kim caught a fish that was 9/10 of a meter long. Doug caught a fish that was 2/3 as long as Kim's fish.

Kim caught a fish of length = 9/10 m

Doug caught a fish of length = 2/3 as long as Kim's fish.

= 2/3 x 9/10

= 18 / 30

= 3/5

Thus, Doug caught a fish that was 3/5 meters long.

Ilya [14]

Answer: Option 'E' is correct.

Step-by-step explanation:

Marginal utility is the addition utility derived from each successive unit of a particular good.

so, marginal utility is the change in utility from consuming an addition unit of a good or service.

Mathematically, it is expressed as

$MU=\dfrac{\Delta TU}{\Delta Q}$

Hence, Option 'E' is correct.

Point A is at (3, -8) and point B is at (7, 3). Point M is the midpoint of point A and point B.

IgorC [24]

The midpoint of point A and point B is (5, -2.5)

<h3>How to determine the midpoint?</h3>

The coordinates are given as:

A = (3, -8)

B = (7, -3)

The midpoint is calculated as:

(x, y) = 0.5 * (x1 + x2, y1 + y2)

So, we have:

(x, y) = 0.5 * (3 + 7, -8 + 3)

This gives

(x, y) = 0.5 * (10, -5)

Evaluate

(x, y) = (5, -2.5)

Hence, the midpoint of point A and point B is (5, -2.5)
