Answer:
Step-by-step explanation:
Standard form of a circle is given by,
(x - a)² + (y - b)² = r²
Here, (a, b) is the center and 'r' is the radius of the circle.
For a circle having center (8, -4) and radius r = 1
Equation of the circle will be,
(x - 8)² + (y + 4)² = 1²
(x - 8)² + (y + 4)² = 1
Option (1) is the answer.
Question (2)
Circle with the center (-1, 0) and a point (2, -4) on it,
Radius of the circle = Distance between the center and the given point on circumference
= [tex]\sqrt{(x_1-x_2)^2+(y_1-y_2)^2}[/tex]
= [tex]\sqrt{(-1-2)^2+(0+4)^2}[/tex]
= [tex]\sqrt{9+16}[/tex]
= 5
Therefore, equation of the circle will be,
(x + 1)² + (y - 0)² = 5²
(x + 1)² + y² = 25

Answer:
1. True
2. True
Step-by-step explanation:
So we are playing with variables here, lets look at 1.
5x + 9 = 29 if x = 4
This means that if x equals 4, would it make the equation true? Let's find out :
Substitute :
5(4) + 9 = 29
20 + 9 = 29
This is true, let's do the same for 2. :
7x - 8 = 13 if x = 3
7(3) - 8 = 13
21 - 8 = 13
This is also true.

Answer:
m<1=117
m<2=99
Step-by-step explanation:
Answer:
Angle 1 is 117 degrees.
Angle 2 is 59 degrees.
Step-by-step explanation:
Let angle 1 be x, and angle 2 be y.
By the exterior angle theorem, x + 21 = 138, so x = 138 - 21 = 117.
Again, by the exterior angle theorem, 79 + y = x = 138, so y = 138 - 79 = 59.
A recipe for a fruit drink calls for 2 cups of fruit juice for every 5 cups of water. Look at each drink mix. Does each drink mix follow the recipe?

1 cup of fruit juice and 2.5 cups of water. Yes. No.
7 cups of fruit juice and 17 cups of water. Yes. No.
Answers
2. No
3. Yes
4.no
Answer:
A. Yes
B. No
C. Yes
D. No
Step-by-step explanation:
A and C has an equivalent ratio.
B and D do not.
2:5 x2 = 4:10
Because if we multiply 2 on both the 2 cups of fruit juice and the 5 cups of water we'll get
4:10 which is the ratio of A
If we divide both the 2 cups of fruit juice and the 5 cups of water with 2 we'll get...
2 ÷ 2 = 1
5 ÷ 2 = 2.5
1:2.5 is the ratio for C.
So both C and A are correct
The rest, B and D, are not equivalent.

Answer:
A Between 1.43 in. and 1.47 in.
Step-by-step explanation:
If the circumference is between 9 and 9.25 inches, and we know that circumference equals 2 * pi * radius, we can solve to find that the radius equals the circumference divided by 2pi. So we get between 1.43 in and 1.47in

Find the measure for < LQR
Answers
Answer:
A
Step-by-step explanation:
90 - 12b = - 3b + 63
- 12b + 3b = 63 - 90
- 9b = - 27
- b = - 27/9
-b = -3
b = 3
to find the measure of MQR:
-3*3 + 63 = 54°
to find the measure of LQR:
180 - 54 = 126° + 1 = 127°
====================================================
Work Shown:
Angles MQX and LQR are vertical angles, so they are equal to one another.
angle MQX = angle LQR
-4a+139 = 4a+123
-4a-4a = 123-139
-8a = -16
a = -16/(-8)
a = 2
Use this to find each angle
angle MQX = -4a+139 = -4*2+139 = 131angle LQR = 4a+123 = 4*2+123 = 131We get the same value 131 each time, so this confirms we have the correct value for 'a', and it confirms our answer for angle LQR.

Your digital camera has a 512 megabyte memory card. You take pictures at two resolutions, a low resolution requiring 4 megabytes of memory per photo and a high resolution requiring 8 megabytes of memory per photo. Write an equation to model the amount of each kind of photo you can take.
Answers
One possible answer is 8H + 4L = 512
=======================================================
Explanation:
H = number of high resolution photosL = number of low resolution photosH and L are placeholders for positive whole numbers, or 0 could replace either variable.
1 high resolution photo takes up 8 mb of space, so H of them take up 8H megabytes of space.
1 low resolution photo takes up 4 mb of space, so L of them take up 4L megabytes.
Overall, the two types of photos take up 8H+4L megabytes, which is equal to 512 since that's the max capacity. That leads to the equation 8H+4L = 512
----------------------------------
Extra info:
There are other ways to express the equation 8H+4L = 512. We could divide each part by 4 to get 2H+L = 128, but I think this equation loses its descriptive quality in a way. We no longer can see that each high resolution photo takes up 8 megabytes (instead we might mistakenly think only 2 megabytes are used per high resolution photo). A similar mistake may happen with the low resolution photos also.
The equation 2H+L = 128 can be rearranged into L = -2H+128 when solving for L.

Answer:
x=4
Step-by-step explanation:
3 (x+2) = 9 (6-x)

Determine if the expressions 100 divided by (25 divided by 5) and (100 divided by 25) divided by 5 are equivalent. If so, tell what property is applied. If not explain why.
Answers
Answer:
They aren't equivalent because when using P.E.M.D.A.S you solve what is in the parenthesis first. After you solve what is in the parenthesis the two expressions are completely different.
Step-by-step explanation:
100/(5)=20 (4)/5= .8
The requried results of the two expressions are different (20 and 0.8), the expressions are not equivalent.
Expression 1:
100 ÷ (25 ÷ 5)
Evaluate the expression inside the parentheses.
25 ÷ 5 = 5
Replace the expression inside the parentheses with its result:
100 ÷ 5
Perform the division:
100 ÷ 5 = 20
So, the result of Expression 1 is 20.
Expression 2:
(100 ÷ 25) ÷ 5
Evaluate the expression inside the first set of parentheses.
100 ÷ 25 = 4
Replace the expression inside the first set of parentheses with its result:
4 ÷ 5
Perform the division:
4 ÷ 5 = 0.8
So, the result of Expression 2 is 0.8.
Since the results of the two expressions are different (20 and 0.8), the expressions are not equivalent.
The reason why they are not equivalent is due to the order of operations. In Expression 1, we first divide 25 by 5 and then divide 100 by the result, while in Expression 2, we first divide 100 by 25 and then divide the result by 5.
