Equations
Solve: y - 5 = -14
y = -9
In order for a relation to be a function, this cannot repeat.
What are the "x-values"?
In Triangle ABC, angle A is 37o, angle B is 68o, what is the measure of angle C?
What is 75o?
The answer to an equation or system of equations.
What is a solution?
Write the following in exponent form.
(3)(3)(3)(3)(a)(a)
What is 34a2?
Solve: 2x + 5 = 23
x = 9
Is it a function? Explain.
{(3, 2), (-3, 2), (5, 2), (-5, 2)}
This is a function because the x-values do not repeat.
Is it possible to have two right angles in a triangle? Why or why not?
What is NOPE!
Solve the system below:
x - y = 11
2x + y = 19
What is (10, -1)?
Simplify:
(2x5)(-3x6)
What is -6x11?
Solve: 5n + 4 - 8n = -5
n = 3
The test used to determine if a graphed image is a function.
What is the vertical line test?
If one remote interior angle is a right angle, and the other measures 45o, what is the measure of the exterior angle?
What is 135o?
Solve the system below:
-6x + 5y = 1
6x + 4y = -10
What is (-1, -1)?
Simplify:
x2/x9
Hint - There should be no negative exponents in your final answer.
What is 1/x7?
Solve: 7 + 3h = -1 - 5h
h = -1
The set below does NOT represent a function. Find two possible values for x.
{(1, 3), (x, 5), (4, 6)}
What is 1 and 4?
These two things exist if you have similar triangles.
Congruent angles and proportional sides.
Solve the system below:
y = 3x - 1
7x + 2y = 37
What is (3, 8)?
Simplify:
(7xy3z4)2
What is 49x2y6z8?
Solve: 5(t + 2) = 25 + 2t
t = 5
Which ordered pair represents a point that falls on the graphed line: y = 2x - 4
a) (2, 4)
b) (6, 8)
c) (-2, 0)
d) (5, 1)
What is B?!
The remote interior angles of a triangle are represented by 2x and 90 degrees. The exterior angle is represented by 4x + 10. Solve for x.
x = 40
Set up the system of equations for the problem below:
A shopper bought 6 shirts and 8 hats for $700. A week later, for the same prices, the shopper bought 9 shirts and 4 hats for $660. Find the cost of one shirt.
6s + 8h = 700
9s + 4h = 660
Simplify:
8x-3
Hint - There should be no negative exponents in your final answer.
What is 8/x3?
