Answer:

[tex]\frac{35}{2}[/tex] - [tex]7n[/tex]

Step-by-step explanation:

7/1 − 3( 7/3n − 7/2 )

Anything divided by one gives itself.

7 - 3 ( [tex]\frac{7}{3}n - \frac{7}{2}[/tex])

Use the distributive property to multiply −3 by  [tex]\frac{7}{3}n - \frac{7}{2}[/tex])

7 - 3 × ([tex]\frac{7}{3}[/tex][tex]n[/tex] - 3 (-[tex]\frac{7}{2}[/tex])

Multiply −3 times [tex]\frac{7}{3}[/tex]

7 - 7n - 3 (-[tex]\frac{7}{2}[/tex])

Express -3 (-[tex]\frac{7}{2}[/tex]) as a single fraction.

7 - 7n + [tex]\frac{-3(-7)}{2}[/tex]

Multiply −3 and −7 to get 21.

7 - 7n + [tex]\frac{21}{2}[/tex]

Convert 7 to fraction [tex]\frac{14}{2}[/tex]

[tex]\frac{14}{2}[/tex] - 7n +  [tex]\frac{21}{2}[/tex]

Since [tex]\frac{14}{2}[/tex] and [tex]\frac{21}{2}[/tex] have the same denominator, add them by adding their numerators.

[tex]\frac{14 + 21}{2} - 7n[/tex]

Add 14 and 21 to get 35.

[tex]\frac{35}{2} - 7n[/tex]

I'm pretty sure the answer to y=−x. Write equation for (8,2) is y=x-6. The opposite of the x is -8, hence, (-8,2) is y=-x-6 is the answer

1. The equation of the line which is parallel and goes through the point (-8, 2) is,

y = x + 10

2. The equation of the line which is parallel and goes through the point (8, 2) is,

⇒ y = x - 6

What is Equation of line?

The equation of the line in slope-intercept form is expressed as:

y - y₁ = m(x - x₁)

where: m is the slope.

and (x₁, y₁) is the point on the line.

1. Given that;

Equation of the line as y = -x

Get the slope of the line,

y = -x

m = -1

Since, The required line is parallel to this line,

So, the required slope will be -1

Now, Get the required equation as,

y - y₁ = m(x - x₁)

y - 2 = 1 ( x - (-8) )

y - 2 = x + 8

y = x + 8 + 2

y = x + 10

Hence, The equation of the line which is parallel and goes through the point (-8, 2) is,

⇒ y = x + 10

2.  Given that;

Equation of the line as y = -x

Point as (8, 2)

Get the slope of the line,

y = -x

m = -1

Since, The required line is parallel to this line,

So, the required slope will be -1

Now, Get the required equation as,

y - y₁ = m(x - x₁)

y - 2 = 1 ( x - 8 )

y - 2 = x - 8

y = x - 8 + 2

y = x - 6

Hence, The equation of the line which is parallel and goes through the point (8, 2) is,

⇒ y = x - 6

Thus,

1. The equation of the line which is parallel and goes through the point (-8, 2) is,

y = x + 10

2. The equation of the line which is parallel and goes through the point (8, 2) is,

⇒ y = x - 6

Answer:

50%

Step-by-step explanation:

The distribution is symmetrical about  the y-axis.

The probability that z is greater than zero in a standard normal distribution is 0.5 or 50%.

The branch which deals with the occurrence of a random event is known as probability.

The area under the curve to the right of z = 0 is equal to the area under the curve to the left of z = 0. So the standard normal distribution is symmetric about the mean of zero

As the total area under the curve is equal to 1, each of these areas must be 0.5 or 50%.

In a standard normal distribution, the probability that z is greater than zero is 0.5, or 50%.

Therefore, the probability that z is greater than zero in a standard normal distribution is 0.5 or 50%.

Answer:

A) 1/3

B) 3

Step-by-step explanation:

PART A: To calculate the scale factor reduction going from the large shape to the small shape you have to use the equation SF reduction = small/large. Using the figures on the side of the shape I need to have 3/9, which simplifies to get 1/3. This is the final answer.

PART B: To calculate the scale factor enlargement going from the small shape to the large shape you have to use the equation SF enlargement = large/small. Using the figures on the side of the shape I need to have 9/3, which simplifies to get 3. This is the final answer.

Answer:

Answers in Bold

Step-by-step explanation:

Point Slope Form: (y - y₁) = m(x - x₁)

4. y - 4 = 0.8(x - 2)

   - To make it slope-intercept form

   y - 4 = 0.8x - 1.6

   y = 0.8x + 2.4

5. (Use slope finding formula) 4 - 10 / -2 - (-5) = 2

   y - 4 = 2(x + 2)

   - To make it slope-intercept form

   y - 4 = 2x + 4

   y = 2x + 8

Answer:

$513.75

Step-by-step explanation:

Let h represent the number of hours he worked in a week

An auto mechanic earns $498.75 in 35 hours during the week. His pay is $2.50 more per hour on weekends.

Hence, his pay Is represented by equation:

$498.75 + $2.50 × x

If he works 6 hours on the weekend in addition to the 35 hours during the week

$498.75 + $2.50 × 6

= $498.75 + $15

= $513.75

Therefore, he earns $513.75

Answer: C, 6.875 is the correct answer

Step-by-step explanation:

AC = 6 - 1.875 = 4.125

AB = 5/3 * 4.125 = 6.875

The measure of AB is 6.875. Therefore, option C is the correct answer.

Given that, the ratio AC: AB = 3: 5.

In mathematics, a ratio indicates how many times one number contains another.

AC = 6 - 1.875 = 4.125

AB = 5/3 * 4.125 = 6.875

Answer:-36

Step-by-step explanation:-3(-1)-12

so negative times negative is positive so -3 x -1 is 3 so now positive times negative is negative so 3 x -12 is -36

The statement which best describes all the possible values of m is –12 < m < 4.

The turning point of a function is defined as the point where the graph of the function changes it's form. That is, an increasing graph changes to decreasing at that point and vice versa.

Given a table values of function.

Also, given that, one of the turning point is at x = -1.

At x = -1, f(x) = 4.

After it, the function decreases.

We can also see another turning point at x = 1.

At x = 1, f(x) = -4.

After x = 1, the function again increases to get the value f(x) = -2.

So x = -2 is not a turning point.

So the value of f(-2) = m lies in between -12 and 4.

Hence the correct option is B.
