What is an Equation?
Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.
It demonstrates the equality of the relationship between the expressions printed on the left and right sides.
Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.
Given data ,
Let the cost of 2 pencils be = A
Now , the equation will be
The cost of 6 pencils is = 36 cents
So ,
The cost of one pencil is = cost of 6 pencils / 6
The cost of one pencil is = 36 / 6
The cost of one pencil is = 6 cents
And , the cost of 2 pencils is calculated by the equation
The cost of two pencils is A = cost of one pencil x 2
The cost of two pencils is A = 6 x 2
The cost of two pencils is A = 12 cents
Therefore , the value of A is 12 cents
Hence , The cost of 2 pencils is 12 cents

Find the missing side length of this right triangle
Answer:
Choice A.
Step-by-step explanation:
Since this is a right triangle, we can use Pythagorean Theorem to solve for the missing side length.
3² + x² = 8²
9 + x² = 64
x² = 55
x = √55
Therefore, the answer is choice A.
The endpoints of the diameter of a circle have the coordinates (3,8) and (9,16) .
What are the coordinates of the center of the circle?
9514 1404 393
Answer:
(6, 12)
Step-by-step explanation:
The center of the circle is the midpoint of the diameter, the average of the end point coordinates:
((3, 8) +(9, 16))/2 = (3+9, 8+16)/2 = (12, 24)/2 = (6, 12)
The center of the circle is (6, 12).

How much of a radioactive kind of antimony will be left after 120 days if you start with 904 grams and the half-life is 60 days?
==========================================
Explanation:
1/2 = 0.5
Every 60 days, the amount cuts in half.
We start with 904 grams and after 60 days, we have 904*0.5 = 452 grams left over.
After another 60 days, we have 452*0.5 = 226 grams left over.
-------------
Alternative Method:
We can apply the half-life formula.
y = a*(0.5)^(x/H)
where,
y = final amount after x daysa = initial amountx = number of days that elapseH = number of days in a half-lifeIn this case,
a = 904 is the starting amountH = 60 is the number of days until another half-life occursWhen x = 120 days go by, we have....
y = a*(0.5)^(x/H)
y = 904*(0.5)^(x/60)
y = 904*(0.5)^(120/60)
y = 904*(0.5)^(2)
y = 904*(0.25)
y = 226 grams of antimony left over.
This method is preferred over the first method if you have x be some non-multiple of 60, or if x is fairly large.

X = -3 -2 -1 0 1 2 3
Y = 10 -2
Answer:
x = -3: [tex]y = 10[/tex], x = -2: [tex]y = 4[/tex], x = -1: [tex]y = 0[/tex], x = 0: [tex]y = -2[/tex], x = 1: [tex]y = -2[/tex], x = 2: [tex]y = 0[/tex], x = 3: [tex]y = 4[/tex]
Step-by-step explanation:
Let [tex]y = x^{2}-x-2[/tex], where [tex]x[/tex] and [tex]y[/tex] are the independent and dependent variables, respectively. The approach consists in evaluating the function at values presented in statement:
x = -3
[tex]y = (-3)^{2}-(-3)-2[/tex]
[tex]y = 10[/tex]
x = -2
[tex]y = (-2)^{2}-(-2)-2[/tex]
[tex]y = 4[/tex]
x = -1
[tex]y = (-1)^{2}-(-1)-2[/tex]
[tex]y = 0[/tex]
x = 0
[tex]y = (0)^{2}-(0)-2[/tex]
[tex]y = -2[/tex]
x = 1
[tex]y = (1)^{2}-(1)-2[/tex]
[tex]y = -2[/tex]
x = 2
[tex]y = (2)^{2}-(2)-2[/tex]
[tex]y = 0[/tex]
x = 3
[tex]y = (3)^{2}-(3)-2[/tex]
[tex]y = 4[/tex]
