The slope-intercept form of the equation of the line containing the points (−2, 4) and (6, 0) will be y =0.5 x+ 5.

A numerical assessment of a line's angle relative to the ground is known as the slope.

The inclination of any line, ray, or line segment is the fraction of the perpendicular to the horizontal distance between any two positions on it.

The slope of the line is found as;

[tex]\rm m = \frac{y_2-y_1}{x_2-x_1} \\\\ m = \frac{0-4}{6-(-2)} \\\\ m = \frac{-4}{8} \\\\ m = \frac{-1}{2}[/tex]

The standard line equation is;

y-y₁=m(x-x₁)

[tex]\rm y-4= \frac{-1}{2}(x-(-2)) \\\\ 2y-8 = x+2 \\\\ 2y =x+10 \\\\ y = 0.5 x + 5[/tex]

Hence, the slope-intercept form of the equation of the line containing the points (−2, 4) and (6, 0) will be y =0.5 x+ 5.

Answer:

y = -7/8x - 1 1/2

Step-by-step explanation:

m = y2 - y1/ x2 - x1 is how you find the m in y=mx+b

(I converted the fractions to decimals)

substitute you slope and (x,y)

y = mx + b

-5 = -0.875(4) + b

-5 = -3.50 + b

-1.50 = b

b = -1.50

[tex] \frac{6}{7} x = 2[/tex]

[tex]x = 2 \div \frac{6}{7} = 2 \times \frac{7}{6} = \frac{7}{3} = 2 \frac{1}{3} [/tex]

Answer:

[tex]2\frac{1}{3}[/tex]

Step-by-step explanation:

So this question is essentially asking how many 6/7s can fit into 2/1. Or in other words, what is 2 divided by 6/7. This gives you the equation: [tex]\frac{2}{1}\div\frac{6}{7}[/tex]. Whenever you're dividing by a fraction, you just keep the first fraction (don't change anything), change the operation (from division to multiplication) and "flip" the fraction so if you had the fraction a/b it's now b/a. This gives you the equation: [tex]\frac{2}{1}*\frac{7}{6}[/tex]. You can now just multiply the denominator and numerator. This gives you the fraction: [tex]\frac{2*7}{1*6}[/tex] which simplifies to [tex]\frac{14}{6}[/tex]. This can be further simplified by dividing both the numerator and denominator by 2. If you don't know why this keeps the original value think of it as multiplying the fraction by [tex]\frac{0.5}{0.5}[/tex] or [tex]\frac{\frac{1}{2}}{\frac{1}{2}}[/tex]. Which is technically multiplying the value by 1, so it should keep the original value, you're just simplifying the numerator and denominator. Simplifying it, gives you the fraction: [tex]\frac{7}{3}[/tex]. This can be a mixed fraction by splitting it up into two parts: [tex]\frac{6}{3}+\frac{1}{3}[/tex]. Which when added is the same thing, except the second side simplifies, and you get [tex]2\frac{1}{3}[/tex]

The measure of angles x and y are 90 degrees and 59 degrees.

A rhombus is a two-dimensional shape having four parallel opposite pairs of straight, equal sides. This shape resembles a diamond and is what you'd find on a deck of cards to represent the diamond suit. Rhombuses can be encountered in a variety of common situations.

We have shown the rhombus in the picture.

As we know the diagonals bisect at a 90-degree angle.

So angle x = 90 degree

To find the value of y:

31 + y + 90 = 180

y = 59 degrees

Thus, the measure of angles x and y are 90 degrees and 59 degrees.

The average rate of change of the function from n = 1 to n = 5 is 3.36 plants per day

The function is given as:

f(n) = 10(1.02)^n

The maximum height is 11.04

So, we have:

10(1.02)^n = 11.04

Divide by 10

1.02^n = 1.104

Take the log of both sides

n * log(1.02) = log(1.104)

Divide by log(1.02)

n = 5

Hence, the reasonable domain is 0 ≤ n < 5

We have:

f(n) = 10(1.02)^n

Set n to 0

f(0) = 10(1.02)^0

Evaluate

f(0) = 10

Hence, the y-intercept is 10

We have:

f(n) = 10(1.02)^n

Calculate f(1) and f(5)

f(1) = 10(1.02)^1 = 10.2

f(5) = 10(1.02)^5 = 10.2

The average rate is then calculated as:

m = (f(5) - f(1))/(5 - 1)

This gives

m =(11.04 - 10.2)(5 - 1)

Evaluate

m = 3.36

Hence, the average rate of change of the function f(n) from n = 1 to n = 5 is 3.36

We conclude that the measure of that angle is 150 degrees.

Notice that  the measure of angle ∠BFE will be equal to:

∠BFE = ∠BFC + ∠CFD + ∠DFE

Where:

∠CFD = 90°

∠DFE = 30°

And we will have that:

∠AFC = 180° - 90° - 30° = 60°

And we know that BF bisects that angle, then:

∠BFC = 30°

So we conclude that:

∠BFE = ∠BFC + ∠CFD + ∠DFE = 30° + 90° + 30° = 150°

We conclude that the measure of that angle is 150 degrees.

By using triangle properties and the law of the cosine twice, we find that the distance between points M and N is approximately 9.8 meters.

In this problem we must determine the distance between two points that are part of a triangle and we can take advantage of properties of triangles to find it. First, we determine the measure of angle L by the law of the cosine:

[tex]\cos L = \frac{(19.6\,m)^{2}-(14.8\,m)^{2}-(21.4\,m)^{2}}{-2\cdot (14.8\,m)\cdot (21.4\,m)}[/tex]

L ≈ 62.464°

Then, we get the distance between points M and N by the law of the cosine once again:

[tex]MN = \sqrt{(7.4\,m)^{2}+(10.7\,m)^{2}-2\cdot (7.4\,m)\cdot (10.7\,m)\cdot \cos 62.464^{\circ}}[/tex]

MN ≈ 9.8 m

Charlotte is 96 years old and Rachel is 292 years old

Let c represent Charlotte's age and r represents Rachels's age

From the question, we have:

c = r - 195

2 years later, we have:

r + 2 = 3(c + 2)

Expand the equation

r + 2 = 3c + 6

Subtract 2 from both sides

r = 3c + 4

Substitute r = 3c + 4 in c = r - 195

c = 3c + 4 - 195

Evaluate the like terms

-2c = -191

Divide by -2

c = 95.5

Approximate

c = 96

Substitute c = 96 in r = 3c + 4

r = 3*96 + 4

Evaluate

r = 292

Hence, Charlotte is 96 years old and Rachel is 292 years old
