The equation of the line with the given properties is y - 17 = 3/2(x - 18)

Linear equations are equations that have constant average rates of change.

The points are given as

(8, 17)

The slope is given as

Slope = 3/2

Calculate the slope of the points using

m = (y2 - y1)/(x2 - x1)

Where

Slope = m = 3/2

(x1, y1) = (8, 17)

So, we have

3/2 = (y - 17)/(x - 8)

Cross multiply in the above equation

So, we have

y - 17 = 3/2(x - 18)

A linear equation is represented as

y = m(x - x1) + y1

In point-slope form, we have

y - y1 = m(x - x1)

By comparing y - y1 = m(x - x1) and y - 17 = 3/2(x - 18), we can see that

y - 17 = 3/2(x - 18) is in point-slope form

Hence, the equation in point-slope form of the line that passes through the point (8, 17) is y - 17 = 3/2(x - 18)

The quadratic equation in standard form that contains the points (5, - 6), (- 7, 0) and (3, 0) is y = - (1 / 4) · x² - x + 21 / 4.

Herein we find the equation of a parabola that contains a points and its x-intercepts (two real roots). According to fundamental theorem of algebra, we can derive a quadratic function with real coefficients if we know three points of the parabola. The procedure is shown below.

First, use the quadratic function in product form and substitute on all known variables to determine the lead coefficient:

y = a · (x + 7) · (x - 3)

- 6 = a · (5 + 7) · (5 - 3)

- 6 = a · 12 · 2

- 6 = 24 · a

a = - 6 / 24

a = - 1 / 4

Second, expand the quadratic function into its standard form:

y = - (1 / 4) · (x + 7) · (x - 3)

y = - (1 / 4) · (x² + 4 · x - 21)

y = - (1 / 4) · x² - x + 21 / 4

The quadratic equation in standard form is y = - (1 / 4) · x² - x + 21 / 4.

If 13800 adult Pacific newts made their annual migration between November 2020 and March 2021, Roughly 2/5 didn't survive the trip, then the number of newts survived crossing the road is 8280 newts

The number of adult Pacific newts made their annual migration = 13800

Roughly 2/5 didn't survive the trip

Then the number of newts didn't survive = 13800×(2/5)

= 13800×0.4

= 5520 newts

To find the number of newts survived, we have to use subtraction

The number of newts survived crossing the road = 13800-5520

= 8280 newts

Answer:

64 = x

Step-by-step explanation:

The angles are alternate interior angles and alternate interior angles are equal when the lines are parallel

128 = 2x

Divide each side by 2

128/2 = 2x/2

64 = x

Answer:

x = 64

Step-by-step explanation:

We know that,

If lines are parallel, the alternate angles are also equal.

Therefore,

[tex] \sf2x = 128[/tex]

Now, let us solve for x.

For that, divide both sides by 2.

The variable represents time. The time in which a person runs a mile will depend on the speed of that person, and that can take almost any value, thus, here the variable is continuous.

First, when a variable is discrete and when it is continuous?

A variable is discrete if it only can take some selected values on a given interval, while a variable is continuous if it can take any value (or at least a dense set) of values in that interval.

For example, the numbers that one can roll on a dice form a discrete set, because the values can only be {1, 2, 3, 4, 5, 6}, just to given an example.

Now, in this case, the variable represents time. Time almost always is a continuous variable, in this case, the time is the time in which a person runs a mile. So that variable can take almost any value (depends on the speed of the person).

The combined weight of a large box and a small box is 80 pounds. The truck is transporting 65 large boxes and 55 small boxes. If the truck is carrying a total of 4850 pounds in boxes. This will be illustrated as:

x + y = 80 ...... i

From equation i x = 80 - y

This will be put into equation ii

55(80 - y) + 65y = 4850

4400 - 55y + 65y = 4850

Answer:

Step-by-step explanation:

Given two planes flying in opposite directions are 810 miles apart after 3 hours, and the first is 30 mph slower than the second, you want the speed of each plane.

Let s represent the speed of the slower plane. Then faster plane will have a speed of (s+30). The distance between the planes increases at a rate equal to the sum of their speeds. Distance is the product of speed and time, so we have ...

  distance = speed × time

  810 = (s + (s+30)) × 3

Dividing the equation by 3, we get ...

  270 = 2s +30

  240 = 2s . . . . . . subtract 30

  120 = s . . . . . . . divide by 2

  150 = s+30 . . . the speed of the faster plane

The speed of the first plane is 120 mph; the speed of the second plane is 150 mph.

The rate of the two planes flying in opposite direction was found to be

given data

The first plane is flying 30 mph slower than the second plane.

time = 3 hours

distance = 810 miles

let the rate of the faster plane be x

then rate if the slower plane will be x - 3

rate of both planes

= x + x - 30

= 2x - 30

Finding the rate of each plane

rate of both planes = total distance / total time

2x - 30 = 810 / 3

2x - 30 = 270

2x = 270 + 30

2x = 300

x = 150

Then the slower plane = 150 - 30 = 120 mph

Hence the rate of the faster plane is 150 mph and the rate of the slower plane is 120 mph
