Answer:

24

Step-by-step explanation:

Answer:24

Step-by-step explanation:144/6=24

Answer:

C. 21

Step-by-step explanation:

5 times of x is 5x.

5x + 10 = 35

Remove 10 from both sides to get one side x, and the other side a number.

5x + 10 - 10 = 35 - 10

5x = 25

Both sides of the equation can be divided by 5.

x = 5

3 times of x is 3x.

3x + 6

Substitute in x = 5 from the earlier working.

3(5) + 6

= 15 + 6

= 21

Therefore, the result of 3 times x added to 6 is 21.

Answer:

Graph A

Step-by-step explanation:

First, isolate the y variable and simplify

12 = 3x + 4y

-3x+12=4y

-(3/4)x+3=y

From here, you can tell that your graph has a negative slope and a y-intercept at 3.

Graph A is the only graph with a negative slope.

Answer:

The slope is [tex]-\frac{3}{4}[/tex]

Step-by-step explanation:

To find the slope, you take 2 points and use rise/run. I used (0,1) and (4,-2) because they look like they are being touched by the line. So by looking at the graph, I have to look at how I can get from (0,1) to (4,-2). So from (0,1), I go down 3 units which makes my number -3, over the run which is 4 units to the right, which makes it positive. so I went down 3 and then went right 4, making this    [tex]-\frac{3}{4}[/tex]. You could also use point-slope which means [tex]\frac{y2-y1}{x2-x1}[/tex] or [tex]\frac{-2-1}{4-0}[/tex] which equals the same thing

EF and BC in the trapezoid below are parallel. if ED=35, BC=63, and DC=28

Find the length of BD if EF = 45. Not all figures are rendered to scale.

A trapezoid is a quadrilateral with one pair of opposite sides parallel. It can have right angles (a right trapezoid), and it can have congruent sides (isosceles), but those are not required.

The base angles and the diagonals of an isosceles trapezoid are equal. The intersection point of the diagonals is collinear to the midpoints of the two opposite sides. Opposite sides of an isosceles trapezoid are of the same length or congruent to each other.

The slope-intercept form will be easier to write the equation of the line.

An equation of the line is defined as a linear equation having a degree of one. The equation of the line contains two variables x and y. And the third parameter is the slope of the line which represents the elevation of the line.

The equation of the line for the slope and intercept form is y = mx + c. Where m is the slope of the line and c is the y-intercept of the line.

Therefore, the slope-intercept form will be easier to write the equation of the line.

What Is the Square Root of 175? The square root of 175 is defined as the value obtained on the multiplication of an integer by itself which will give the final product as 175. As there is no such integer which on multiplication with itself will give 175 exactly, the square root of 175 is not a whole number.

Answer:

Step-by-step explanation:

Any 1 of the following transformations will work. There are others that are also possible.

translation up 4 units, followed by rotation CCW by 90°.

rotation CCW by 90°, followed by translation left 4 units.

rotation CCW 90° about the center (-2, -2).

Step-by-step explanation:

The order of vertices ABC is clockwise, as is the order of vertices A'B'C'. Thus, if reflection is involved, there are two (or some other even number of) reflections.

The orientation of line CA is to the east. The orientation of line C'A' is to the north, so the figure has been rotated 90° CCW. In general, such rotation can be accomplished by a single transformation about a suitably chosen center. Here, we're told there is a sequence of transformations involved, so a single rotation is probably not of interest.

If we rotate the figure 90° CCW, we find it ends up 4 units east of the final position. So, one possible transformation is 90° CCW + translation left 4 units.

If we rotate the final figure 90° CW, we find it ends up 4 units north of the starting position. So, another possible transformation is translation up 4 units + rotation 90° CCW.

Of course, rotation 90° CCW in either case is the same as rotation 270° CW.

5x = x + 2(12)

5x = x + 24

4x = 24

x = 6

5(x)

5(6) = 30

Our standard linear slope equation is:

mx + b = y

We're told our slope is 1/2, so that's our m value.

When x = 0 our value is 5. If you need this visualized, then:

1/2 * 0 +b = 5

0 + b = 5

b = 5

So our equation looks like:

x/2 + 5 = y

Answer: The symbol ∈ indicates set membership and means “is an element of” so that the statement k∈R means that k is an element of the set R. In other words, k is one of the objects in the collection of (possibly many) objects in the set R.

-4 is a rational number...

The circle is a plane figure whose circumference is given by the formulae [tex]2\pi r[/tex]. Where r is the radius of the circle.

The area of the circle is given by the formulae [tex]\pi r^{2}[/tex] where again r is the radius of the circle and pie is the common factor in both the formulae

We also need to know that the radius of the circle is the half of the diameter of the circle and the diameter is twice the radius

From which we can derive the relation; d=2r where d is the diameter of the circle.

So, the formulae now in terms of diameter becomes [tex]\pi d[/tex] for circumference and [tex]\frac{\pi d^{2} }{4}[/tex] for area of the circle.
