Evaluate each expression if a = 2, b = -34
3. - 9 (a-6)

Answer:

Step-by-step explanation:

The Buddha taught that just as individual states had laws, there was a universal law. Each person's station in life was a reflection of their karma, or the cumulative extent to which they had followed or broken the universal law in previous lives.  Chinese leaders began to appoint skilled bureaucrats rather than solely employing hereditary officeholders, and Confucian thinkers held that people became fully developed members of society through a process of education, rather than simply by noble birth.

Answer:

y=5x+11

Step-by-step explanation:

using point-slope equation, we substitute.

parallel lines have the same slope.

y-y¹=m(x-x¹)

y-6=5(x+1)

y-6=5x+5

y=5x+11

Answer:

Find the equation of a line given that you know a point of point on the line in the slopes the equation of the line is typically written as y=mx+b where am is slope and b is the y- intercept

Answer: m = 1/3

Step-by-step explanation:

Answer:

B

Step-by-step explanation:

only one that gives the y value of 9 for the x value of 1

The m variable is the slope of the line and controls its 'steepness'. A positive value has the slope going up to the right. A negative slope goes down to the right. The b variable is the y intercept - the point where the line crosses the y axis.

example 1                                                    

y = mx + b

m = slope b = y-intercept

y = 3x - 1

m = 3 and b = -1

example 2

y = b + mx

b = y-intercept m = slope

y = 5 - 1/2x

m =- 1/2 and b = 5

The simplified expression is:

[tex]\frac{2}{5}y+\frac{1}{5}x-0.2y-6+\left(-2\right)=0.2y+0.2x-8[/tex]

Step-by-step explanation:

Given the expression

[tex]\frac{2}{5}y+\frac{1}{5}x-0.2y-6+\left(-2\right)[/tex]

[tex]\mathrm{Remove\:parentheses}:\quad \left(-a\right)=-a[/tex]

[tex]=\frac{2}{5}y+\frac{1}{5}x-0.2y-6-2[/tex]

[tex]\mathrm{Group\:like\:terms}[/tex]

[tex]=\frac{2}{5}y-0.2y+\frac{1}{5}x-6-2[/tex]

Add similar elements

[tex]=0.2y+\frac{1}{5}x-6-2[/tex]

[tex]=0.2y+\frac{x}{5}-6-2[/tex]

[tex]=0.2y+\frac{x}{5}-8[/tex]

[tex]=0.2y+0.2x-8[/tex]

Thus, the simplified expression is:

[tex]\frac{2}{5}y+\frac{1}{5}x-0.2y-6+\left(-2\right)=0.2y+0.2x-8[/tex]

Answer:

5 miles

Step-by-step explanation:

There are 60 minutes in 1 hour, so to find how many miles he can walk, we simply multiply:

[tex]60 min * \frac{1 mile}{12 min} = 5 miles[/tex]

Answer:

Yes. It is an obtuse triangle

when 1/2 divided by (-8 / 12), it is equivalent to ( -3 /4)

Let an expression be 'x'

Given that, an expression must exist that is equivalent to -3/4 when divided by (-8/12).

This leads us to the conclusion that = x / (-8 / 12) = -3 / 4

It is equivalent to = x * (- 12 / 8) = -3 / 4

We get = x * (- 12 / 8) * (- 8 / 12) = -3 / 4 * (-8 / 12) by multiplying (- 8 / 12) on both sides.

We get = x = - 3/ 4 * (-8 / 12) by canceling like numbers.

x = 24 / 48

x = 1 / 2

Therefore, 1/2 divided by (-8 / 12) equals (-3 / 4).

Answer:

The standard deviation of the weight, σ, is approximately 4.73 kg

Step-by-step explanation:

The weights of the six puppies are;

[tex]x_i[/tex] = 1, 2, 7, 7, 10, and 15

The number of puppies, n = 6

Therefore, we have;

The mean = μ = ∑x/n = (1 + 2 + 7 + 7 + 10 + 15)/6 = 7

The standard deviation, σ, is given as follows;

[tex]\sigma =\sqrt{\dfrac{\sum \left (x_i-\mu \right )^{2} }{n}}[/tex]

By substituting, we have;

[tex]\sigma =\sqrt{\dfrac{ \left (1-7 \right )^{2} + \left (2-7 \right )^{2} + \left (7-7 \right )^{2} + \left (7-7 \right )^{2} + \left (10-7 \right )^{2} + \left (15-7 \right )^{2} }{6}}[/tex]

Simplifying gives;

[tex]\sigma =\sqrt{\dfrac{ \left (-6 \right )^{2} + \left (-5 \right )^{2} + \left (0 \right )^{2} + \left (0 \right )^{2} + \left (3 \right )^{2} + \left (8 \right )^{2} }{6}} =\sqrt{\dfrac{ 36 + 25 + 0 +0+ 9 + 64 }{6}}[/tex]

[tex]\sigma =\sqrt{\dfrac{ 134 }{6}} = \sqrt{\dfrac{67}{3} } \approx 4.72582[/tex]

The standard deviation of the weight, σ ≈ 4.73 kg to two decimal places.

Answer: rise is 4 and run is 5

Step-by-step explanation:

Answer:

down below

Step-by-step explanation:

To find the rise over run, you need to pick a point that intersects one of the axises. Then, you need to find a point that intersects the other axis. Third, you find the first point and begin moving up or down until you reach the height of the other point. From there, you count along that height line until you reach the second point. The number from counting on the y axis is the rise and the number from counting on the x axis is the run. So, you take the rise and put it over the run.

Answer:

y = -9/8x +7

Step-by-step explanation:

We know two points on the line so we can find the slope

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

m = ( -2 -7)/(8 -0)

  = -9/8

We also know the y intercept which is 7

The slope intercept form of the line is

y = mx+b where m is the slope and b is the y intercept

y = -9/8x +7

Answer:

[tex]y=-\frac{9}{8}x+7[/tex]

Step-by-step explanation:

Slope-intercept form is y=mx+b

Use the formula for slope: m=(y2-y1)/(x2-x1)

m=(-2-7)/(8-0)

m=-9/8

The graph shows that b, the y-intercept, is at (0,7)

Therefore, the final equation is [tex]y=-\frac{9}{8}x+7[/tex]

Step-by-step explanation:

I think x=-2

The value of x is 11. Then the length of the line segment PR, PQ, and QR will be 52, 30, and 22, respectively.

An axis is a term used to describe a line on which points are located, particularly if that line is connected to a triangle or other geometric shape. Since two factors determine a line, two points are transparently collinear. If the points are in a line, then the points are collinear points.

Let A, B, and C be the collinear points. Then the condition of the collinear will be

AB + BC = AC

PQ = 2x + 8, QR = x + 11, and PR = 5x - 3.​ From the figure, the points P, Q, and R are the collinear points. Then we have

PQ + QR = PR

2x + 8 + x + 11 = 5x - 3

3x + 19 = 5x - 3

22 = 2x

x = 11

Then the line segment PR, PQ, and QR will be

PQ = 2 × 11 + 8

PQ = 22 + 8

PQ = 30

QR = 11 + 11

QR = 22

PR = 5 × 11 - 3

PR = 55 - 3

PR = 52

The value of x is 11. Then the length of the line segment PR, PQ, and QR will be 52, 30, and 22, respectively.
