Answer:
(2,-5) and (2,1).
Step-by-step explanation:
We need to find the find all the points having an x coordinate of 2 whose distance from the point (-2,-4) is 5.
A circle with center (-2,-4) and radius 5 represents all the points whose distance from the point (-2,-4) is 5.
Standard form of a circle is
[tex](x-h)^2+(y-k)^2=r^2[/tex]
where, (h,k) is center and r is the radius.
[tex](x-(-2))^2+(y-(-4))^2=(5)^2[/tex]
[tex](x+2)^2+(y+2)^2=25[/tex]
Now, put x=2.
[tex](2+2)^2+(y+2)^2=25[/tex]
[tex](4)^2+(y+2)^2=25[/tex]
[tex](y+2)^2=25-16[/tex]
[tex](y+2)^2=9[/tex]
Taking square root on both sides.
[tex]y+2=\pm\sqrt{9}[/tex]
[tex]y+2=\pm3[/tex]
[tex]y+2=-3\text{ or }y+2=3[/tex]
[tex]y=-5\text{ or }y=1[/tex]
So, the y-coordinates of the points are -5 and 1.
Therefore, the required points are (2,-5) and (2,1).

20 (20 minus x) = 300 What is the value of x?
Answer:
5
Step-by-step explanation:
20 ( 20 - x ) = 300
By transposing,
20 - x = 300 / 20
20 - x = 15
-x = 15 - 20
-x = -5
- and - get cancelled
so, x = 5

Violet was given a box of assorted chocolates for her birthday. Each night, Violet treated herself to some chocolates. Violet ate 4 chocolates each night and there were originally 24 chocolates in the box. Write an equation for C,C, in terms of t,t, representing the number of chocolates remaining in the box tt days after Violet's birthday.
Answer:
C = 24 - 4t
Step-by-step explanation:
Total chocolate = 24 chocolate
Quantity eaten each night = 4
Let
C = number of chocolate remaining
t = number of days after violet birthday
Number of chocolate remaining = original number of chocolate - 4(number of days after violet birthday)
C = 24 - 4t
For instance, if t = 2
That is, 2 days after violet birthday
C = 24 - 4t
= 24 - 4(2)
= 24 - 8
= 16
Answer: C = 24 - 4t

Mike had $1,800 in his bank account. Thirty days later, his account balance was $570. Write an integer an integer to represent the average change in his balance each day during his time
Answer:
The average change in balance each day during his time $41
Step-by-step explanation:
Here, we want to write an integer to represent the average balance change in the 30 days period.
First, let’s find difference between opening and closing balance= (1800-570) = 1230
We shall now divide this by 30 = 1230/30 = $41
Answer:
The average chang in his time is 41
Step-by-step explanation:
A pet store has k tanks of fish. Each tank has 28 fish. Using , write an expression for the total number of fish in the store.
Answer:
28k
Step-by-step explanation:
There are k tanks with 28 fish each
The total number of fish is
28k
Answer: 28k
k represents the number of fish tanks.
If we have that then we can multiply and solve for the total number of fish.
Best of Luck!

Peaches are being sold for $2 per pound. If x represents the number of pounds of peaches bought and y represents the total cost of the peaches, which best describes the values of x and y?
The values of both x and y can be any real number.
The values of both x and y will be real numbers greater than or equal to 0.
The value of x and y will always be zero
The value of x can be any real number greater than or equal to 0, but the value of y must be an integer greater than or equal to 0.
Answer:
the answer is #4 -The value of x can be any real number greater than or equal to 0, but the value of y must be an integer greater than or equal to 0.

What is the slope of the line ?
Step-by-step explanation:
The slope of a line characterizes the direction of a line. To find the slope, you divide the difference of the y-coordinates of 2 points on a line by the difference of the x-coordinates of those same 2 points .
Answer:
To find the slope, you will have to divide the difference of the y-coordinates of 2 points on a line by the difference of the x-coordinates of those h same 2 points .
Step-by-step explanation:
the length of a rectangle is twice its width. the perimeter of the rectangle is 42cm. what is the length and width for the rectangle?
Answer:
length = 14cm width = 7cm
Step-by-step explanation:
length = 2x w (width)
if length = 2x width then
length must equal 4/6 and width must equal 2/6 because length is 2 times width.
42 divded by 6 = 7.
length gets four lots of 7.
length of both sides= 28cm
width gets 2 lots of 7.
width of both sides= 14cm
there are two sides for length and two sides for width.
Length x 2= 28cm
Length must equal 14cm.
Width x 2 = 14cm
Width must equal 7cm.
lets just prove this is true:
7+7=14.
14+ (14+14) =
14+ 28= 42cm.
this works.
the length is 14cm and the width is 7cm.
Answer:
Length = 14 cm
width = 7 cm
Step-by-step explanation:
given:
rectangle
where L = 2W
W = W
Perimeter = 42 cm
find: Length of L
solution:
Perimeter or a rectangle = 2L + 2W
plugin the given values into the formula:
42 = 2(2W) + 2W
42 = 4W +2W
42 = 6W
W = 42/6
W = 7 cm (width of Rectangle)
solve L by using substituting W=7 in L = 2W
L = 2W
L = 2 (7)
L = 14 cm
therefore, the Length = 14 cm
width = 7 cm
