What is a variable

 A variable is a letter that represents an unknown number or quantity

200

Solve: X(x-2)

X² -2x

300

0⁰

Anything to the power of 0 is 1, even 0⁰

400

X²-2x(x+y²-3)

-x² - 2xy² + 6x

500

7a(a²-3b(b³-2a)a²-7a+6b⁴)

Yeah good luck

-21a³b⁴ + 42a⁴b + 42ab⁴ + 7a³ - 49a²

Linear Function

100

what is the slope of equation: y = 2

0

200

what is the x intercept of the line: 2x + 9y - 20 = 0

10

300

What is the equation of the line that passes through the points: (-1,3) (6,9)

y = 6/7x + 27/7

400

what is the equation of the line that is parallel to the given and passes through a point:

5x - 4y +17 = 0

(-3,6)

y = 5/4x + 39/4

500

What is the equation of the line perpendicular to the given and passes through the point:

-3/2x +7y -3/1 = 0

(2/3, -7/5)

y = -14/3x +77/45

Polynomials

100

Classify this polynomial: 4ab²

monomial

200

state the degree and constant of this polynomial: 

4ab² +b⁴a³ + 5

Degree is 7, Constant is 5

300

state the degree, coefficient, and classify 21

degree is 0, coefficient is 21.

It is a constant

400

factor x²-64

(X+8)(x-8)

500

Factor 4x²+12xy+9y²-9r²-24rs-16s²

^{Yeah u never solving this}

(2x+3y+3r+4s)(2x+3y-3r-4s)

Surface Area & Volume

100

Forumla for cube Sa & Volume

SA  - 6s²

v - s³

200

Angles

100

What do the angles in a triangle add up to

180^o

200

what are corresponding angles

corresponding angles are angles that form when 2 parallel lines are crossed by a transversal. these angles have the same value 

300

How do inscribed and central angles relate?

C = 2I

I - Inscribed

400

Find the value of the central angle if the inscribed angle is 20^o

40^o

500

angles in a parallelogram measure: 3x + 14, 4x + 12, ?, ?. Find the missing angles

x = 22.

66+14 = 80

88+12 = 100

The other angles are also 100, and 80
