Answer:
3x^2 - 3x - 3
Step-by-step explanation:
Plug in the equations in place of the variables
First, subtract k(x) from h(x)
x^2+1-x-2 (combine like terms)
x^2 - x -1
Next, multiply the new equation by 3
3(x^2 - x - 1) Use distributive property
= 3x^2 - 3x - 3

This circle is centered at the point (2,6), and the length of its radius is 4. What is the equation of the circle?
Answer:
The equation of the circle with centre (h,k) and radius (r) can be written as :-
[tex] \\ \qquad \sf \: {(x - h)}^{2} + {(y - k)}^{2} = {r}^{2} \\ [/tex]
So, we are given with :-
h = 2 k = 6 r = 4Now, by putting their value we can write the equation as :-
[tex] \\ \qquad\sf \: {(x - 2)}^{2} - {(y - 6)}^{2} = {4}^{2} (16) \\ [/tex]
Expanding this, we get :-
[tex] \\ \sf {x}^{2} - 4x + 4 + { y}^{2} - 12y + 36 = 16 \\ [/tex]
Rearranging and by subtracting by 16 from both sides we got standard polynomial as -
[tex] \\ \sf \: {x}^{2} + {y}^{2} - 4x - 12y + 20 = 0 \\ [/tex]

Please mark Brainliest!!! =DThis is what I need help with.
∠A and ∠ B ∠B are complementary angles. If m ∠ A = ( 2 x − 10 ) ∘ ∠A=(2x−10) ∘ and m ∠ B = ( x − 2 ) ∘ ∠B=(x−2) ∘ , then find the measure of ∠ A ∠A.
Answer:
Angle A = 58 degrees
Angle B = 32 degrees
Step-by-step explanation:
First of all, we will need to know that complementary angles are angles that sum up to 90 degrees.
This means that if we add the values of angle A and angle B, they will both sum up to 90 degrees.
i.e (2x-10) + (x-2) = 90
3x -12 = 90
3x = 102
x = 34 degrees
We can substitute this value of x into the equations for angles A and B
A = (2 X (34) - 10 ) = 58 degrees
B = ( 34 - 2) = 32 degrees
Therefore, angles A and B are 54 and 32 degrees respectively.
Check: We can add the two angles to see if we get 90 degrees. 58 + 32 = 90 degrees. This shows that the two angles are complementary and our answer is correct.

Mary is half of her sister's age. The sum of their
ages is 18. How old is her sister?
Answer:
Mary's sister is 12 years old.
Step-by-step explanation:
If Mary is half of her sister's age, her sister is 2 times her age.
Represent M as Mary's age...
M+2m=18
3m=18
3m/3=18/3
m=6
But because Mary is a half of her sister's age...
6*2=12
Answer:
12 years
Step-by-step explanation:
12/2 = 6
12 + 6 = 18
The formula for the surface area of a cylinder is 2\pi r(r+h)2πr(r+h)2, pi, r, left parenthesis, r, plus, h, right parenthesis where rrr is the radius of the cylinder's base and hhh is its height. A certain pole has a cylinder-like shape, where the base's radius is 101010 centimeters and the height is 222 meters. What calculation will give us the estimated surface area of the pole in square centimeters?
Answer:
2pi x 10 x 210
Step-by-step explanation:
The estimated surface area of the pole is 13194.68 square centimeters and this can be determined by using the given data.
Given :
The formula for the surface area of a cylinder is [tex]2\pi r(r+h)[/tex].A certain pole has a cylinder-like shape, where the base's radius is 10 centimeters and the height is 2 meters.The following steps can be used in order to determine the surface area of the pole in square centimeters:
Step 1 - According to the given data, the surface area of a cylinder is [tex]2\pi r(r+h)[/tex].
Step 2 - Now, substitute the values of 'r' and 'h' in the expression of the area of the cylinder.
[tex]A = 2\pi\times 10\times (10+200)[/tex]
Step 3 - Simplify the above expression.
[tex]A = 2\pi\times 10\times (210)[/tex]
[tex]A = 13194.68\; {\rm cm^2}[/tex]
So, the estimated surface area of the pole is 13194.68 square centimeters.

a and Ly started sung money at the same time for Christmas gis erika started with $100 and added $35 a week. Uly saved $60 a week and
started with 25. How many weeks will it take for them to have the same amount of money saved for Christmas gifts?
weeks torna and Ly to have the same amount of money saved up
Answer:
Step-by-step explanation:
Erika: y = 35x + 100
Ly: y = 60x + 25
60x + 25 = 35x + 100
25x + 25 = 100
25x = 75
x= 3 weeks
Erika: y = $35(3) + 100= 105 + 100 = $205
Ly: 60(3) + 25 = 180 + 25 = $205

slope-intercept form: y = mx + b
m = the slope and b = the y-intercept.
We know that the line passes through x-coordinate 1 and y-coordinate 1 and has a slope of 2
Let's plug our numbers into the slope-intercept form
1 = 2(1) + b
Simplify the right side
1 = 2 + b
Subtract 2 from both sides
-1 = b
The final answer: y = 2x - 1
