The numerical length of BC is 36

The given parameters are:

AC= 64, AB = 7x + 8, and BC = 3x + 6.

The above means that the point B is between points A and C

So, we  have

AC = AB + BC

Substitute the known values in the above equation

64 = 7x + 8 + 3x + 6

Evaluate the like terms

10x = 50

Divide both sides by 10

x = 5

Substitute x = 5 in BC = 3x + 6

So, we have

BC = 3 x  10 + 6

Evaluate

BC = 36

Hence, the numerical length of BC is 36

The points that are located 3 units from (-4,-2) are (-1, 2), (-7, 2), (-4, -1) and (-4, 5)

The point is given as

Point = (-4, 2)

The distance is given as

Distance = 5

The points that are located 3 units from (-4,-2) are calculated using

Points = (x ± 3, y) and (x, y ± 3)

So, we have

Points = (-4 ± 3, 2) and (-4, 2 ± 3)

Expand

Points = (-4 + 3, 2), (-4 - 3, 2), (-4, 2 - 3) and (-4, 2 + 3)

Evaluate the sum and the difference

Points = (-1, 2), (-7, 2), (-4, -1) and (-4, 5)

Hence, the points that are located 3 units from (-4,-2) are (-1, 2), (-7, 2), (-4, -1) and (-4, 5)

The number in the equation is -10.

Given,

The sum of a number and three is ​tripled the result is one less than twice the number.

We can take the number as x.

Then,

3(x + 3) = (2x - 1)

Equate the above equation and find x.

3x + 9 = 2x - 1

Add -2x to both sides:

That is,

3x - 2x + 9 = 2x - 2x - 1

x + 9 = -1

Add -9 to both sides:

We get,

x + 9 - 9 = -1 - 9

x = -10.

That is, the number in the equation is -10.

Ok so I was very confused on this too. Not even going to lie to ya, I struggled with this for a long time. However once you get the hang of it, it's actually rather simple.

So, lets try a problem. What is 0.04 as a fraction?

Well, we know that 0.04 is 4%. And you can do [tex]\frac{4}{100}[/tex] which is 0.04, or 4%

Does that make sense? If not let me explain it a little more.

Well basically all you have to do is put that number over 100.

Here are some examples of decimals to percentage to fraction:

0.5 = 50% = [tex]\frac{50}{100}[/tex] or in simplest form [tex]\frac{1}{2}[/tex]

0.11 = 11% = [tex]\frac{11}{100}[/tex]

0.03 = 3% = [tex]\frac{3}{100}[/tex]

I really hope this helped you!!!

If not let me know how i can explain it and what doesn't make sense!

Answer: To convert a decimal to a fraction, place the decimal number over its place value. For example, in 0.6, the six is in the tenths place, so we place 6 over 10 to create the equivalent fraction, [tex]\frac{6}{10}[/tex]. If needed, simplify the fraction.

Step-by-step explanation:

Option C) is correct which is Adam started the construction at the wrong place. He should have started at point R and drawn an arc across both rays.

According to the question we can see that Adam first draws an arc on a line and draws the bisector, which gives him the error.

We know that when we construct an angle bisector, first we put the compass on the point of the angle and make an arc and from that arc we make two arcs that intersect at a point. Then we draw a ray from the point of angle to that intersecting point which gives us the angle bisector.

Here Adam didn't draw the arc from point R.

Thus, Adam started the construction at the wrong place. He should have started at point R and drawn an arc across both rays.

Hence option C) is the correct option.

Answer: -5/2

Step-by-step explanation:

4y−10∣=20

Combine like terms and use the properties of equality to get the variable on one side of the equal sign and the numbers on the other side. ∣4y−10∣=20 Use the definition of absolute value.

4y−10=20

4y−10=−20

Add 10 to both sides of the equation. 4y=30 which then equals  4y=−10

Divide both sides by 4 to get y = 15 over 2 converted to y = negative 5 over 2

(hope this is helpful)

The equation that models the data will be y = 3 + x and for x = 12, y will be 15.

We are given the equation:

y = a + b x

Also, we have some points of the equation as:

X         2         3         4         5         6           8

Y         5         6         8         9         10         12​

For the point ( 2 , 5 ), we have the equation as:

5 = a + b ( 2 )

5 = a + 2 b

a = 5 - 2 b   …(1)

For the point (3 , 6), we have the equation as:

6 = a + b (3)

6 = a + 3 b

a = 6 - 3 b   …(2)

From (1) and (2), we get that:

5 - 2 b = 6 - 3 b

3 b - 2 b = 6 - 5

b = 1

a = 5 - 2

a = 3

So, the equation will become:

y = 3  +  x

For x = 12, we get the value of y as:

y = 3 + 12

y = 15

Therefore, we get that, the equation that models the data will be y = 3 + x and for x = 12, y will be 15.

Answer:

8*z^2-3

Step-by-step explanation:

1) (c) The range of the function f(x) = 3x² + 6x - 8 is {y|y ≥ –11}.

2) (d) The x-intercepts of the graph of the function f(x) = x² + 4x - 12 are ( - 6, 0) and ( 2, 0 ).

1). A parabola opens upward and it passes through ( - 3, 0) and ( 1, 0), and has vertex at ( - 1, - 11 ).

We have the function for the parabola f(x) = 3x² + 6x - 8.

Vertex and the coefficient of the quadratic term are two features of a parabola that aid in determining its range.

Therefore, the critique point of the range and a portion of the constraint is the vertex's vertical coordinate. The next step is to determine if the parabola is concave up or down. The parabola is concave up in this issue if the coefficient of the quadratic terms is positive. As a result of the parabola's concave upward shape, all real numbers greater than - 11 fall into the function's permissible range.

Hence, the range of the function is {y|y ≥ –11}.

2). The graph of the function with the equation f(x) = x² + 4x - 12 is a parabola that opens upward, passes between the points ( - 6, 0) and ( 2, 0), and its vertex is at ( - 6, 0). ( - 2, - 16). It is the y-intercept ( 0, - 12).

The x-intercepts are the locations where the graph and x-axis meet. The y-coordinate of these points is always zero. A parabola can only have two x-intercepts at most. As we can see, the parabola passes through the points ( - 6, 0) and ( 2, 0), and have y coordinates 0, hence the x-intercepts are ( - 6, 0) and ( 2, 0).

The value of x from the given parallel lines, using corresponding angles concept, we get 32°.

Given that, straight line m parallel to straight line n and t is the transversal.

The corresponding angles definition tells us that when two parallel lines are intersected by a third one, the angles that occupy the same relative position at each intersection are known to be corresponding angles to each other.

Here, x°=32°

Therefore, the value of x from the given parallel lines is 32°.

Answer:

  70

Step-by-step explanation:

You want the number of paths from corner to corner on a 5×5 grid with no backtracking.

The geometry of the problem matches that of Pascal's triangle, attached.

In the attached figure, the value at each node is the sum of the values above and to the left. This matches the counting process for paths that can be used to get to any particular point on the grid: the total number of ways to get there is the sum of the ways it can be approached from above and the ways it can be approached from the left.

The given grid has some numbers filled in. If we continue to assign values to nodes that are the sum of the values above and to the left, we find the node values match the upper left 5×5 array of values in the attachment.

The value at the lower right corner of that array is 70. That is, ...

there are 70 ways to get from A to B.

__

Alternate solution

The path taken will always have 8 steps. Of those, 4 must be to the right, and 4 must be down. The number of ways we can choose 4 of those 8 steps to be steps to the right is "8 choose 4" ...

  C(8,4) = 8!/(4!(8-4)!) = (8·7·6·5)/(4·3·2·1) = 70

Of course, using Pascal's triangle is simply another way to find the value of C(n,k).

It has been 8 months since I joined the gym.

3. check your work

The value of x is 12.

Given that the angles are m∠DBC=(12X-18) and m∠ABD=(8x+30).

An angle is made when two rays are joined together at any common point.

We will find the value of x by equating both the given angles as

m∠DBC=m∠ABD

Now, we will substitute the values of angles as

12x-18=8x+30

Further, we will subtract 18 from both sides and simplify it as

12x-18+18=8x+30+18

12x=8x+48

Now, we will subtract 8x from both sides and simplify as

12x-8x=8x+48-8x

4x=48

Now, we will divide both sides by 4, we get

4x/4=48/4

x=12

Hence, the value of x when m∠DBC=(12x-18) and m∠ABD=(8x+30) is 12.
