Answers

Answer:

Monkey: -5/2

Step-by-step explanation:

monkey = x

3x + 4 = -x - 6

3x + x = -6 - 4

4x = -10

4x/4 = -10/4

x = -5/2

Check:

3x + 4 = -x - 6

3(-5/2) + 4 = -(-5/2) - 6

-15/2 + 4 = 5/2 - 6

-15/2 + 8/2 = -3.5

-7/2 = -3.5

-3.5 = -3.5

What are coordinates in a graph?

The coordinates in a graph indicate the location of a point with respect to the x-axis and y-axis.

The coordinates in a graph show the relationship between the information plotted on the given x-axis and y-axis.

We have,

y + 4 = 25 ( x + 3)

Some coordinates on the graph are:

When x = 0,

y + 4 = 175

y = 175 - 4

y = 171

When x = 1,

y + 4 = 25 (1 + 3)

y = 100 - 4

y = 96

3x−y=1?

Answers

Step-by-step explanation:

We wish to express 3x - y = 1

in slope-intercept form.

3x - y = 1

=> y = 3x - 1

Slope of line = 3, therefore

Slope of parallel line is also 3.

We have y = 3x + c.

When x = 1, y = 7.

=> (7) = 3(1) + c, c = 4

Hence the answer is y = 3x + 4.

x + 3 = 0

y = 1

C 6.333.... inches
D 6.333....Kilometers ​

Answers

Answer:

3.75 inches is the correct answer..

Answer:

A. 3.75 inches

Step-by-step explanation:

The question is asking for the amount of inches not kilometers, so options B and D are automatically incorrect. I took the three inches and divided it by the four kilometers to kind inches per kilometer. The times the inches by five to get the correct answer;

3 inches = 4 kilometers

3 / 4 = 0.75

0.75 = 1 kilometer

0.75 x 5 = 3.75

3.75 inches = 5 kilometers

Answers

This question has this set of answer choices:

a) when the plane cuts three faces of the cube, separating one corner from the others

b) when the plane passes through a pair of vertices that do not share a common face

c) when the plane is perpendicular to the base and intersects two adjacent vertical faces

d) when the plane makes an acute angle to the base and intersects three vertical faces

e) not enough information to answer the question

The right answer is the first choice: a) when the plane cuts three faces of the cube, separating one corner from the others

9. Melissa is making a set of 5 bulletin boards for her friends. She plans to decorate the bulletin boards with a strip of ribbon across each diagonal. If the bulletin boards are 12 in by 24 in, about how many total inches of ribbon will she use for all 5 boards? show work​

Answers

Answer:

Melissa will need 7200 square inches of ribbon to make the 5 bulletin boards.

Step-by-step explanation:

Since Melissa is making 5 bulletin boards for her friends, and each one measures 12 inches wide by 24 inches long, to determine the number of inches that Melissa should use in total, the following calculation must be performed:

12 x 5 + 24 x 5 = X

60 x 120 = X

7,200 = X

So, Melissa will need 7200 square inches of ribbon to make the 5 bulletin boards.

Answer:

y=93°, z=79°

Step-by-step explanation:

Lines and Angles

There are properties of lines and angles that will help us to find the required values.

The vertex at the bottom left side of the quadrilateral has two angles that were formed when two lines crossed. Those are called linear angles, and they always add up to 180°.

This means that z is the angle needed to complete 180°, that is:

z = 180° - 101° = 79°

Now the quadrilateral must have the sum of its internal angles equal to 360°. We have three of them that sum: 100°+88°+79°=267°.

This means y is the angle needed to complete 360°, or:

y = 360° - 267° = 93°

Answer: y=93°, z=79°

Find slope
11x - 6y = -36

Answers

Answer:

11/6

Step-by-step explanation:

To isolate the y on one side of the equation, you must first subtract 11x from both sides. Then the equation becomes -6y = -11x - 36.

Then you must divide both sides by -6 to isolate the y. The coefficient of the variable x becomes -11/-6, which is just 11/6.

Answer:

I would say D. There is no logical explanation for the final answer but there is for everything else.

For A: Makes sense because 3x-2 are in parenthesis outside a number so you can multiply.

For B: Makes sense because you are allowed to add/subtract like terms but in this case only subtracting would make sense, (which is what they did) since you want to get all the like terms on one side.

For C: Makes sense because you are trying to simplify the equation, and they are both like terms (they are both numbers that have no letter attached to them) and they are on the opposite side making them able to be simplified.

For D: No idea what the point is.
