Answer:
(x + 4)^2 + (y – 9)^2 = 25
Step-by-step explanation:
The standard form for a circle is
[tex](x - h)^{2} + (y - k)^{2} = r^{2}[/tex] where (h, k) is the center and r is the radius
In your case, h = -4 and k = 9 and r = 5
So, (x + 4)^2 + (y – 9)^2 = 25
The equation for this circle is given as
[tex](x+4)^2 + (y-9)^2 = 25[/tex]
Data
h = -4k = 9r = diameter/2 = 10/2 = 5Equation of CircleThe equation of circle is given by
[tex](x-h)^2 + (y-k)^2 = r^2[/tex]
Let's substitute our values and get our equation
[tex](x--4)^2 + (y-9)^2 = 5^2\\(x+4)^2 + (y-9)^2 = 25[/tex]
we substituted the values of h and k and made sure it's in the standard form of equation of a circle.
The equation for this circle is given as
[tex](x+4)^2 + (y-9)^2 = 25[/tex]
This looks exactly like
[tex](x-h)^2 + (y-k)^2 = r^2[/tex]

The graph of line p represents = x-1. If the slope of line p is multiplied by (-10)
to create liner, which statement about the graphs of the two lines is true?
A
Line r intersects line p.
B Line ris parallel to line 2.
CLine ris 10 units above line p.
D
Line ris 10 units below line p.
Answer:
A. Line r intersects line p
Step-by-step explanation:
to find the second graph multiply the slope of line p by -10
slope is 1/5 or 0.2
So,
0.2 * -10 = -2
slope of second line is -2

drawing a vowel from letter tiles that spell out MATHEMATICS
chance
Blank 1:
Blank 2:
Answer:
3/ 8 ; 3/8
Step-by-step explanation:
MATHEMATICS
vowels in mathematics = (A, E, I)
letters in mathematics = (M, A, T, H, E, I, C, S)
Probability = required outcome / Total possible outcomes
Required outcome = vowels in mathematics = 3
Total possible outcomes = letters in mathematics = 8
Probability of drawing a vowel letter tiles = 3/8
2.)
Spinner division :
Red = 4 ; white =2 ; green = 1 ; blue = 1
Total divisions = 8
Probability (landing on blue) = number of blue / total
P(landing on blue) = 1 / 8
P(landing on white) = 2/ 8 = 1/4
P(landing on blue or white) = 1/8 + 2/8 = 3/8

For which function k does the output increase by 20% every time the input increases by 1?
Answer:
k(x) = 1.20^x
Step-by-step explanation:
Here, we want to get a function
The output in this case refers to k(x)
the input refers to the value x
So, for every 1 increase in x, we want k(x) to increase by 20%
20% is same as 20/100 = 0.2
So at an initial value of 1, each increase if 20% will be 0.2 + 1 = 1.2
So therefore, we have the function as;
k(x) = 1.20^x
Tell how many solutions each one has
Answer:
Step-by-step explanation:
1) 3(x + 2 ) +4 = 31
3*x + 2*3 + 4 = 31
3x + 6 + 4 = 31
3x + 10 = 31 {Subtract 10 from both sides}
3x = 31 - 10
3x = 21 {divide both sides by 3}
x = 21/3
x = 7
This equation has one solution
2) 3x + 1 = 3x + 9
Subtract 3x form both sides
3x + 1 -3x = 3x + 9 - 3x
1 ≠ 9
There is no solution for this equation.
3) 2x - 4 = 2x -4
This equation has many solution
