A line connecting the points (-3,0) and (x, -6)has slope -1. Determine x.

Answer:

20%

Step-by-step explanation:

Take the amount of rent and put it over the total amount of money to find  the percent

800/4000 =.2

Change to percent form by multiplying by 100

.2 * 100 = 20%

The value of x is 5. The correct option is the second option-  5

From the question, we are to determine the value of x

By the proportionality theorem, we have that

If three or more parallel lines intersect two transversals, then they cut off the transversals proportionally.

Considering the diagram, we can write that

[tex]\frac{12}{28 }= \frac{35-4x}{35}[/tex]

Then, we get

12 × 35 = 28(35-4x)

420 = 980 -112x

112x = 980 - 420

112x = 560

x = 560/ 112

x = 5

Hence, the value of x is 5. The correct option is the second option-  5

Answer:

It should be 7.

Step-by-step explanation:

If y = 4 multiply 2 by 4 equals eight, then you have 8x-8=48. Do the opposite of subtraction to both sides the 8 cancels on the left side add 8 to 48 you get 56 now all you have to is get x by it self to get that do the opposite of multiplication divide both sides by 8 and you should get 7.

The first step that we need to take before attempting to solve the problem is to understand what the problem is asking us to do and what they are giving us to help solve the problem.  Looking at the problem statement they are asking for us to determine the probability that a point will randomly be plotted in the shaded region.  We are not given much of anything else which means that we will need to use our own numbers.

The picture that was provided has a square with four equal circles inside right next to each other.  Therefore, we can say that each side of the square is going to be 2 units which causes the diameter of the circle to be half that or 1 unit.  We can go even further and determine that the radius is going to be 0.5 units for each circle.  Let's determine the area of all the shapes.

Area of the square

Area of a circle

The area that we got from the circle only gives us the area for one of the circles so we need to multiply the number by four to give us the total area of the circles.

Total area of the circles

Now that we determined the area of both the square and the circles we can move onto the part of finding the probability of a point randomly landing on a circle.

Determine the probability

However, now that we have determined what the probability, looking at the answer options we can see that all of the are in percentages.  So let's convert our probability into a percentage.

Convert to percentage

Therefore, looking at the options given, the option that would best fit this choice would be option B, about 80%.

Answer:

Option D graph

Step-by-step explanation:

x - 4 ≥ - 1

add 4 to both sides, x - 4 + 4 ≥ - 1 + 4

x ≥ 3

so x is greater than or equal to 3

- equal to means closed dot at 3

- greater than means arrow to the right of 3

The ratio of the difference of the two means to Sidney’s mean absolute deviation is; 4/3.28

From the given table, we see that;

Mean grade of Sidney = 82

Mean grade of Phil = 78.

Mean absolute deviation of Sidney = 3.28

Mean absolute deviation of Phil = 3.96.

The difference between the two means of Sidney and Phil = 82 - 78 = 4.

Thus, the ratio of the difference of the two means to Sidney’s mean absolute deviation is; 4/3.28

Complete Question is;

Because x is the number of boxes in the shipment, we conclude that the correct option is "the maximum weight allowed in a shipment"

Remember that for a function f(x), the y-intercept is given by f(0).

In this case, the graph represents the amount of allowed weight remaining in a shipment depending on the number of boxes of screws included.

Then the variable x represents "the number of boxes of screws in the shipment".

So when x = 0, there are no boxes.

Then the y-intercepts represents the remaining weight when there are no boxes of screws, which would be all the allowed weight on the shipment.

The correct option is:

"the maximum weight allowed in a shipment"

m= y2-y1/x2-x1

= (1-0)/(0-2)

= -1/2

The first rational expression simplifies to (m - 1).

The second rational expression simplifies to (m - 2) / m.

The third rational expression simplifies to (m - 2) / (m - 1).

An expression contains one or more terms with addition, subtraction, multiplication, and division.

We always combine the like terms in an expression when we simplify.

We also keep all the like terms on one side of the expression if we are dealing with two sides of an expression.

Example:

1 + 3x + 4y = 7 is an expression.com

3 + 4 is an expression.

2 x 4 + 6 x 7 – 9 is an expression.

33 + 77 – 88 is an expression.

We have,

(m² - 2m + 1) / (m - 1)

(m² - 2m + 1) / (m - 1)

= (m - 1) / 1

= m - 1

The first rational expression simplifies to (m - 1).

(m² - 3m + 2) / (m² - m)

(m² - 3m + 2)

= (m - 1)(m - 2)

(m² - m)

= m(m - 1)

So,

(m² - 3m + 2) / (m² - m)

= (m - 2) / m

The second rational expression simplifies to (m - 2) / m.

(m² - m - 2) / (m² - 1)

(m² - m - 2)

= (m - 2)(m + 1)

(m² - 1)

= (m - 1)(m + 1)

So,

(m² - m - 2) / (m² - 1)

= (m - 2) / (m - 1)

The third rational expression simplifies to (m - 2) / (m - 1).

Thus,

The first rational expression simplifies to (m - 1).

The second rational expression simplifies to (m - 2) / m.

The third rational expression simplifies to (m - 2) / (m - 1).

Answer:

V = 150.72 cm³.

Step-by-step explanation:

First, get the volume of a cylinder.

V = πr²h

Where:

π = 3.14 (given)

r = radius (half of diameter, or 2)

h = height (12)

Knowing this, substitute the known values.

V = πr²h

V = (3.14)(2²)(12)

Square 2.

V = (3.14)(4)(12)

Multiply 3.14 and 4.

V = (12.56)(12)
Multiply 12.56 and 12.

V = 150.72.
