Your question is poorly formatted; However, the correct question is:

Point  A  ( 3 , 4 )  and point  M  (5.5,0) is the midpoint of point  A and point B. Determine the coordinates of B

Answer:

The coordinates of B is (8,-4)

Step-by-step explanation:

Given

Point  A  ( 3 , 4 )

Point  M  (5.5,0)

Required

Determine B

Since, M is the midpoint;

We'll solve this question using the following formula;

[tex]M(x,y) = (\frac{x_1 + x_2}{2},\frac{y_1 + y_2}{2})[/tex]

Where [tex](x,y) = (5.5,0)[/tex] and [tex](x_1,y_1) = (3,4)[/tex]

Substitute values for x, y, x1 and y1 in the above formula;

This gives

[tex](5.5,0) = (\frac{3 + x_2}{2},\frac{4 + y_2}{2})[/tex]

By direct comparison, we have

[tex]5.5 = \frac{3 + x_2}{2}[/tex]  and [tex]0 = \frac{4 + y_2}{2}[/tex]

Solving [tex]5.5 = \frac{3 + x_2}{2}[/tex]

Multiply both sides by 2

[tex]11 = 3 +x_2[/tex]

Subtract 3 from both sides

[tex]11- 3 = x_2[/tex]

[tex]x_2 = 8[/tex]

Solving [tex]0 = \frac{4 + y_2}{2}[/tex]

Multiply both sides by 2

[tex]0 = 4 + y_2[/tex]

Subtract 4 from both sides

[tex]0 - 4 = y_2[/tex]

[tex]y_2 = -4[/tex]

Hence;

The coordinates of B is (8,-4)

Answer:

(8,-4)

Answer:

A

Step-by-step explanation:

Answer:

a = 8/29 thus: Step 1 is wrong!

Step-by-step explanation:

Solve for a:

8 - a/2 = 3 (4 - 5 a)

Hint: | Put the fractions in 8 - a/2 over a common denominator.

Put each term in 8 - a/2 over the common denominator 2: 8 - a/2 = 16/2 - a/2:

16/2 - a/2 = 3 (4 - 5 a)

Hint: | Combine 16/2 - a/2 into a single fraction.

16/2 - a/2 = (16 - a)/2:

(16 - a)/2 = 3 (4 - 5 a)

Hint: | Make (16 - a)/2 = 3 (4 - 5 a) simpler by multiplying both sides by a constant.

Multiply both sides by 2:

(2 (16 - a))/2 = 2×3 (4 - 5 a)

Hint: | Cancel common terms in the numerator and denominator of (2 (16 - a))/2.

(2 (16 - a))/2 = 2/2×(16 - a) = 16 - a:

16 - a = 2×3 (4 - 5 a)

Hint: | Multiply 2 and 3 together.

2×3 = 6:

16 - a = 6 (4 - 5 a)

Hint: | Write the linear polynomial on the left hand side in standard form.

Expand out terms of the right hand side:

16 - a = 24 - 30 a

Hint: | Move terms with a to the left hand side.

Add 30 a to both sides:

30 a - a + 16 = (30 a - 30 a) + 24

Hint: | Look for the difference of two identical terms.

30 a - 30 a = 0:

30 a - a + 16 = 24

Hint: | Group like terms in 30 a - a + 16.

Grouping like terms, 30 a - a + 16 = (-a + 30 a) + 16:

(-a + 30 a) + 16 = 24

Hint: | Combine like terms in 30 a - a.

30 a - a = 29 a:

29 a + 16 = 24

Hint: | Isolate terms with a to the left hand side.

Subtract 16 from both sides:

29 a + (16 - 16) = 24 - 16

Hint: | Look for the difference of two identical terms.

16 - 16 = 0:

29 a = 24 - 16

Hint: | Evaluate 24 - 16.

24 - 16 = 8:

29 a = 8

Hint: | Divide both sides by a constant to simplify the equation.

Divide both sides of 29 a = 8 by 29:

(29 a)/29 = 8/29

Hint: | Any nonzero number divided by itself is one.

29/29 = 1:

Answer: a = 8/29

Answer:

0

Step-by-step explanation:

Degree of a term is known as the power of the variable. As the constant term has no variable , the degree of the constant term is 0.

Here 7 is a constant term. As 7 doesn't have any variable , it can be also written as:-[tex]7 = 7x^0[/tex]

And here the power of [tex]x^0\\[/tex] is 0 , so the degree is 0.

Answer:

The answer is 26.

Step-by-step explanation:

When you place the 2 next to the 8 you have to multiply it and then add the 10 to get the answer for the equation which is 26. Put it all in the calculator will be easier by putting it like this 8*2+10.

Figure a has been translated only (translated 9 units to the right)

Figure b has been reflected over the x axis

Figure c has been rotated and translated

=======================================

Explanation:

Pick on a point like (-7,4) and note how it moves 9 units to the right to get to (2,4). All points on the upper left figure follow this same translation rule. This rules in figure a.

Figure b is a result of reflecting over the x axis. The rule used is [tex](x,y) \to (x,-y)[/tex]. The x coordinate stays the same while the y coordinate flips from positive to negative. So for example, (-7,4) flips to (-7,-4)

Figure c is a combination of rotating and translating the original figure. It looks like a 90 counterclockwise rotation has been applied followed by a translation. The actual translation and rotation rules used will depend on how you define the center of rotation.

The figure which is rotated and translated correctly about the x-axis is figure a.

The graph of a function f is that the set of ordered pairs, where\f(x)=y. within the common case where x and f(x) are real numbers, these pairs are Cartesian coordinates of points in two-dimensional space and thus form a subset of this plane.

We have been given four graphs of a function and first function has coordinates (-5,7) (-2,6) (-7,4) (-4,1) and that we must identify correct reflected graph.

The coordinates of a pure reflected graph are going to be (4,7) (2,4) (5,1) (7,6) which are the coordinates of figure a which is in first quadrant.

Hence the proper reflected graph of function having coordinates (-5,7) (-2,6) (-7,4) (-4,1) is that the graph of coordinates (4,7) (2,4) (5,1) (7,6).

Kerrie is tiling the floor of a kitchen. The kitchen floor measures 11.3 feet by 9.25 feet. She orders enough tiles for 99 square feet. Which statement about the amount of tiles is correct?

a) Kerrie estimated correctly by rounding down. She has enough tile. The exact area is 104.5 square feet.

b) Kerrie estimated correctly by rounding up. She has enough tile. The exact area is 104.5 square feet.

c) Kerrie did not estimate correctly by rounding up. She does not have enough tile. The exact area is 104.5 square feet.

d) Kerrie did not estimate correctly by rounding down. She does not have enough tile. The exact area is 104.5 square feet.

Answer:

a) Kerrie estimated correctly by rounding down. She has enough tile. The exact area is 104.5 square feet.

Step-by-step explanation:

In mathematics we have what is defined as rounding up and rounding down.

Rounding up of numbers is when the number you want to round up is followed by number from 5 to 9(5, 6, 7, 8, 9)

E.g. 2.5 rounded up to the nearest whole number = 3

Rounding down of numbers is when the number you want to round up is followed by number from 1 to 4(1, 2, 3, 4)

E.g. 2.4 rounded down = 2

We are told in the question

Kerrie is tiling the floor of a kitchen. The kitchen floor measures 11.3 feet by 9.25 feet. She orders enough tiles for 99 square feet.

Kitchen floor is rectangular = Area = Length × Width

= 11.3 × 9.25 feet

= 104.525 square feet

We are told that Kerrie ordered for 99 square tiles.

But looking at the decimal, the number after the decimal are between 1 and 4.

Hence, she would be rounding down.

If Kerrie rounds down to the nearest whole number

11.3 feet = 11 feet

9.25 feet = 9 feet

Finding the area = 11 feet × 9 feet

= 99 square feet

Therefore, the correct statement = option a) Kerrie estimated correctly by rounding down. She has enough tile. The exact area is 104.5 square feet.

Step-by-step explanation:

Inscribed angles are formed when two chords have 1 common endpoint. The measure of [tex]\angle ACB[/tex] and [tex]\overset{\huge\frown}{AC}[/tex]  are:

[tex]\angle ACB = 32^o[/tex]

[tex]\overset{\huge\frown}{AC} = 146^o[/tex]

Given that:

[tex]\overset{\huge\frown}{AB} = 64^o[/tex]

[tex]\angle ABC = 73^o[/tex]

See attachment

First, we calculate [tex]\angle ACB[/tex] using:

[tex]\angle ACB = \frac{1}{2} \times \overset{\huge\frown}{AB}[/tex] ----- An inscribed angle is half the arc it intercepts

So, we have:

[tex]\angle ACB = \frac{1}{2} \times 64^o[/tex]

[tex]\angle ACB = 32^o[/tex]

Using the same theorem, we calculate [tex]\overset{\huge\frown}{AC}[/tex] as follows:

[tex]\angle ABC = \frac{1}{2} \times \overset{\huge\frown}{AC}[/tex]

So, we have:

[tex]73^o = \frac{1}{2} \times \overset{\huge\frown}{AC}[/tex]

Multiply both sides by 2

[tex]2 \times 73^o = 2 \times \frac{1}{2} \times \overset{\huge\frown}{AC}[/tex]

[tex]2 \times 73^o =\overset{\huge\frown}{AC}[/tex]

[tex]146^o =\overset{\huge\frown}{AC}[/tex]

Hence:

[tex]\overset{\huge\frown}{AC} = 146^o[/tex]

Answer:

  4 square units

Step-by-step explanation:

If you draw a vertical line down the middle of the square, you divide it into two triangles that are congruent to the smaller triangles shown in the figure. Hence each of those triangles has an area of 1/2 square unit.

After you have divided the square as above, you see that two smaller triangles are identical in area to the larger triangles. So, each of those has an area of 2(1/2) = 1 square unit.

Then the total of areas is ...

  2 small triangles + square + 2 large triangles = 2(1/2) + 1 + 2(1) = 4

The area of the rectangle is 4 square units.

though we can still move on to answer as the area of a triangle is expressed as

Area= half base time hight (pronounced)

and stated mathematically as

A= (1/2)b*h

the ideal of the area of a triangle is taken from the area of the rectangle divided into two from the diagonal to form two triangles

the area of a rectangle (shown in the attachment ) = b*h

now since the rectangle consists of two half triangle,

one triangle will have its area to be half the area of the rectangle

hence

Answer:

Step-by-step explanation:

First, you need to get a common denominator.

You can do this by multiplying each fraction by 3 or 4.

See,

5/4 * 3/3=15/12

16+15=31

31/12

Answer:

2(7/12)

Step-by-step explanation:

First, try to match the denominators.

4/3+5/4

To match the denominators, multiply them with each other.If the denominator multiplys with each other, the numerator also have to multiply too.

=[tex]\frac{(4*4)}{(3*4)} +\frac{(5*3)}{(4*3)}[/tex]

= [tex]\frac{16}{12} +\frac{15}{12}[/tex]

= [tex]\frac{16+15}{12}[/tex]

= [tex]\frac{31}{12}[/tex] (If you want it as a improper fraction, you can stop here)But normally we continue till we get a mixed number if we get a improper fraction.

So 31/12 equals to 2(7/12) as a mixed number
