Answer:

  (x -1)² +(y -4)² = 25

Step-by-step explanation:

The equation of a circle in standard form is ...

  (x -h)² +(y -k)² = r² . . . . . . . circle with center (h, k) and radius r

The graph shows your circle has its center at (1, 4) and its radius is 5. Then the equation is ...

  (x -1)² +(y -4)² = 25

Answer:

1.  (-6,-11)

2.(-2,5)

Step-by-step explanation:

y=2x+1

2x-3y =21

Take the first equation and substitute into the second

2x-3(2x+1) =21

Distribute

2x -6x-3 = 21

Combine like terms

-4x -3 = 21

Add 3 to each side

-4x-3+3 =21+3

-4x = 24

Divide by -4

-4x/4 = 24/-4

x = -6

Then find y

y = 2x+1 = 2(-6) +1 =-12+1 = -11

Elimination for problem 2

2x+3y=11 4x-3y=-23

Add the two equations together to eliminate y

2x+3y=11

4x-3y=-23

-----------------

6x = -12

Divide by 6

6x/6 = -12/6

x = -2

Multiply the first equation by -2

-4x+-6y=-22

4x-3y=-23

-----------------

 -9y = -45

Divide by -9

-9y/-9 = -45/-9

y = 5

They are the same amount.

Answer:

I guess D is the correct answer.

Answer:

Hey Natalia,

I suppose A is just what is on the left and B what 8s on the right

so for 5) it would be

A = 6

and

B = 3

Answer:

Step-by-step explanation:

True

Option B is correct that is false.

We have been given a figure we need to tell that the two lines are perpendicular

Lines are perpendicular if they meet at the right angle.

Line CD is perpendicular AB to vice-versa is not true.

Hence, Option B is correct

Lines that intersect each other forming a right angle are called perpendicular lines. Example: the steps of a straight ladder; the opposite sides of a rectangle. The symbol is used to denote two perpendicular lines: ⊥ ⊥ .

The perpendicular symbol is ⊥. It is used between the two lines to show that they are perpendicular to each other. Perpendicular lines intersect at right angles (90°) while parallel lines are parallel to each other and never intersect.

Answer:

the answer is :C midsegment

Step-by-step explanation:

because the LINE SEGMENT is in the MIDDLE of the triangle

Answer:

Since the Line is Perpendicular

m.m'=-1

The line

y=x+8

Comparing with

Y=mx + C

m=1

m.m'=-1

m'=-1/m = -1/1 = -1.

y-y' = m'(x-x')

The point it passes is (-7,8)

y-8= -1(x--7)

y-8=-1(x+7)

y-8 = -x - 7

y + x -1 = 0.

Just Make y the subject

y= -x + 1 ..... This is your answer.

Answer:

The parallel sides are called the bases of the trapezoid

Step-by-step explanation:

[tex]area = (\frac{a + b}{2}) \times h[/tex]

       [tex]= \frac{14.1+22.7}{2} \times 18\\\\=331.2 \ unit^2[/tex]

Answer:

331.2 units^2

Step-by-step explanation:

There is a formula for the area of a trapezoid of legs a and b and width h:

a + b

----------- * h

     2

Here the leg lengths (which are parallel) are 14.1 and 22.7, and the width is 18.  Thus, the desired area is

14.1 + 22.7                        36.8

---------------- * 18  =  A  = ------------ * 18 = 331.2 units^2

Answer:

Step-by-step explanation:

Since there is no single number we can add to one number in the sequence to get to the next one, this is not arithmetic. That means it's geometric, if it's a sequence at all. To get from 2 to 6 we multiply by 3. To get from 6 to 18 we multiply by 3. To get from 18 to 54 we multiply by 3. Therefore, this is in fact geometric and the common ratio is 3. The standard form of a geometric explicit formula is

[tex]A_n=a_1(r)^{n-1[/tex] where n is the position of a number in the sequence, a1 is the first number in the sequence, and r is the common ratio. We have then

a1 = 2 and r = 3. Therefore, the explicit formula is

[tex]A_n=2(3)^{n-1[/tex] and you can use this to find the value of any number in the sequence. Very handy; much more so than the recursive formula, which requires that all the numbers in a sequence be found in order in order to get to a desired value.

Answer: 8 3/4

Explanation: Well in order to solve this equation, you must make the denominators equivalent. A common factor between 4 and 5 is 20. But since we multiplied the denominators, we have to do the same to the numerators. 3 x 5 = 15. 1 x 4 = 4. Our new fractions are now 1 15/20 and 4/20. Now that we have made our denominators equivalent, we can divide. 1 15/20 divided by 4/20 is 8 15/20. But we are not done yet, after we must simplify the fraction. Which would be 8 3/4.

Answer:

C)

Step-by-step explanation:

plug in x-and-y values to see which point makes the equation true:

A) -2 = 3/2(-2) - 4       -2≠-7

B) -4 = 3/2(-2) - 4       -4≠-7

C) -1 = 3/2(2) - 4         -1=-1     [This is true]

D) 1 = 3/2(2) - 4           1≠-1

Answer:

Step-by-step explanation:

If the coordinates are (0, a) and (b, 0), we just use the distance formula to find the distance in terms of a and b:

[tex]d=\sqrt{(0-a)^2+(b-0)^2}[/tex] and

[tex]d=\sqrt{(-a)^2+b^2}[/tex] which simplifies to

[tex]d=\sqrt{a^2+b^2}[/tex]

Answer:

[tex]Change = \$36[/tex]

Step-by-step explanation:

Given

See attachment for line plot

[tex]Amount = \$100[/tex]

Required

Determine the change

First, we calculate the amount represented by the line plot

[tex]Amount (Plot) =10+12+12+14+16[/tex]

[tex]Amount (Plot) =64[/tex]

The change from $100 is then calculated as:

[tex]Change = Amount - Amount (Plot)[/tex]

[tex]Change = \$100 -\$64[/tex]

[tex]Change = \$36[/tex]
