Answer:
The center of the circle;
(2, -1)
The radius of the circle;
r = 4
Step-by-step explanation:
The first step is to complete the square on both x and y;
x^2 + y^2 -4x + 2y - 11 = 0
x^2 -4x +y^2 +2y = 11
We determine c1 to complete the square on x;
c1 = (b/2)^2
c1 = (-4/2)^2 = 4
We then determine c2 to complete the square on y;
c2 = (2/2)^2 = 1
The equation of the circle is then re-written as;
x^2 -4x + 4 +y^2 +2y + 1 = 11 +4 +1
We then factorize the expressions in x and y separately;
(x-2)^2 + (y +1)^2 = 16
The center of the circle is thus;
(2, -1)
The radius is the square root of 16;
r = 4
find the attached.

Answer:
1) 0.75
2) y = [tex]\frac{3}{4}[/tex]x - 3
3) (4, 0); (0, -3)
Step-by-step explanation:
Convert to slope-intercept form (y = mx + b) by solving:
y = [tex]\frac{3}{4}[/tex]x - 3
m is the slope, so [tex]\frac{3}{4}[/tex] or you can write as 0.75.
To find the x and y intercepts, set the y value to zero and solve (x-intercept), and b is the y-intercept.
Ken drives his car 800 miles in 3 days. At this rate, how far will he drive his car in 5 days?
Answer:
1333.35 miles
Step-by-step explanation:
Given: 800 miles in 3 days
To find: How far will he drive his car in 5 days?
Solution: If Ken drives his car 800 miles in 3 days, to find how many miles it will take him at the same rate, we need to divide 800 miles by 3 days
[tex]800[/tex] ÷ [tex]3 =[/tex] [tex]266.666666667[/tex]
Simplified
[tex]266.67[/tex]
Now that has been figured out, we need to multiply the result by the 5 days it will take Ken.
[tex]266.67[/tex] × [tex]5 =[/tex] [tex]1333.35[/tex]
Hence, At the rate of 800 miles in 3 days, Ken will drive 1333.35 miles in 5 days.

Waldo and Freddy caught fish one weekend. The dot plots show the lengths of the fish they caught.
Which statement about the lengths of the fish caught by Waldo and Freddy appears to be true?
Answer:
C
Step-by-step explanation:
Freddy has a range of 22-15 while Waldo's range is 21-15. Thus, Freddy has a range of 7, greater than Waldo's 6.
The true statement is B. The median length of the fish caught by Waldo is greater than Freddy's.
What are mean, median, and mode?The three main methods for identifying the average value of a set of integers are mean, median, and mode.
Adding the numbers together and dividing the result by the total number of numbers in the list yields the arithmetic mean.
The middle value in a list that is arranged from smallest to greatest is called the median.
The value that appears the most frequently on the list is the mode.
The data for Waldo's and Freddy's fish are not skewed to the right.
The median length of Waldo's fish is 18.82 inches and the median for Freddy's fish is 18.76, so the median length of waldo's fish is greater.
No need to check the other statements as only one statement would be true.

Answer:
answer: Hi = 15
Step-by-step explanation:
the larger shape is the same as the smaller shape just flipped over and bigger of course so to find this out you have to take 2 simular angles and find out what multiplied by the small angle will get the big angle so I see angles gh and ba are simular I try 4.5 ÷ 1.5 = 3 so 3 is how much the shape is being multiplied by so bc is simular to hi so I do 5 x 3 = 15 and theres are answer 15 is the length of hi hope this helps you!

Consider the equations below:
y = 2x and 6x = 3y + 5
Are the lines parallel or perpendicular?
A Parallel because the product of the slopes is -1.
B Parallel because the slopes are the same.
C Perpendicular because the product of the slopes
is -1.
D Perpendicular because the slopes are the same.
==========================================================
Explanation:
Let's solve 6x = 3y + 5 for y
6x = 3y + 5
6x-5 = 3y
3y = 6x-5
y = (6x-5)/3
y = (6x)/3 - (5/3)
y = 2x - (5/3)
This final equation is in the form y = mx+b with m = 2 as the slope and b = -5/3 as the y intercept.
With the equation y = 2x, aka y = 2x+0, the m and b values are m = 2 and b = 0 respectively.
We see that both equations have the same slope (m = 2), but different y intercepts. Therefore, the two lines are parallel. If both y intercepts were the same as well, then we'd be talking about the same identical line.
If the slopes multiplied to -1, then the lines are perpendicular. In any other case, the two lines are neither parallel nor perpendicular.
