What is the value of X in this equation:
X + 7 = 0
Solution: X = -7
Explanation: 7 is being added to the variable, so we do the inverse operation which is to subtract 7 from both sides.
Solve this equation:
-9 x (-3)
Answer: 27
What is the definition of the word:
Difference
Answer: The result of a subtraction problem.
On which axis would you find the coordinates (0, 5)?
Answer: On the y-axis.
What is the definition of the word:
Perimeter
Answer: The distance around a 2-dimensional shape.
The perimeter can be calculated by adding up the lengths of all of the sides of the shape.
What is the value of n in this equation:
-3 + n = 3
Solution: n = 6
Explanation: -3 is being added to the variable, so we do the inverse operation which is to subtract -3 from both sides. (subtracting -3 is the same thing as adding 3)
Solve this equation:
-9 ÷ (-3)
Answer: 3
What is the definition of the word:
Origin
Answer: The point at which the x-axis and y-axis intersect; the coordinates are (0,0).
In which quadrant would you find the coordinates (2, 3)?
Answer: In quadrant I
This is a three-dimensional solid shape with six faces including rectangular bases.
Answer: Rectangular Prism
What is the value of x in this equation:
-2x = -2
Solution: x = 1
Explanation: The variable is being multiplied by -2, so we do the inverse operation which is to divide by -2.
Solve this equation:
-8 • 4
Answer: -32
What is the definition of the word:
Equation
Answer: A statement of equality between 2 mathematical expressions. It is indicated by an equal sign.
Example: 3x + 7 = 9
In which quadrant would you find the coordinates (4, -1)?
Answer: In quadrant IV
This is a solid shape with six square faces. Each square face has the same side length and thus all the faces have the same size.
Answer: Cube
What is the value of b in this equation:
6b = 3
Solution: b = 1/2 or 0.5
Explanation: The variable is being multiplied by 6, so we do the inverse operation which is to divide by 6 on both sides.
Solve this equation:
-8 + 20
Answer: 12
What is the definition of the word:
X-axis
Answer: The horizontal axis of a coordinate plane (graph).
What is the name for the ordered pair found at (0,0)?
Answer: Origin
What is a right angle?
Answer: An angle whose measure is 90°
What is the value of b in this equation:
11 + b = -13
Solution: b = -24
Explanation: 11 is being added to the variable, so we do the inverse operation which is to subtract 11 from both sides.
Solve this equation:
12 - (-3)
Answer:15
What is the definition of the word:
Parallel Lines
Answer: Lines that have the same slope and different y-intercepts/Lines that never intersect
Which axis is the horizontal axis?
Answer: x-axis
Explanation: A horizontal line is one that runs straight from left to right, like the x-axis.
What is an obtuse angle?
Answer: An angle whose measure is between 90° 180°
