Equations
Solve:
3 + a = 10
a = 7
Pythagorean theorem is used to determine the side lengths of what kind of triangle?
What is a right triangle.
Slope intercept form of a linear equation.
y=mx + b
True or False: A function can have a repeating input (x-value).
What is false. The input cannot repeat and cannot have more than one output.
What is the formula for the area of a circle?
A = pir^2
Solve:
6 = y - 3
y = 9
A relation where every input has exactly one output.
What is a function?
What is the slope of the line with the equation of y=2x-4.
What is m = 2
Is this a function?
(1,3) (4,7) (5,7) (9,2) (12, 5)
What is yes. The inputs do not have more than one output.
What does C represent?
What is the circumference of a circle.
Solve:
4 + 2c = 8
c = 2
True.
Slope of the line that passes through (2,6) and (4,6).
What is m=o
Is this a linear function?
y = 3x^2+8
What is no because it does not follow y=mx+b due to the exponent of 2.
v = pir^2h
What is the formula for the volume of a cylinder.
Solve:
15 = 3d-3
d = 6
What is slope?
What is the constant rate of change, rise over run, measure of steepness and direction of a line.
What is the slope of the line with the equation of y=-2?
What is m = 0
Is the following a function?
x 8 8 8 8 8
y 2 4 3 12 14
What is no, the inputs (x-values) repeat and have more than output.
What does the capital B on the resource sheet represent?
What is the area of the base shape on the three dimensional shape.
Solve:
-3(x+5) = 2x-5
x = -2
What is an outlier?
What is a point that is far away from the group on a scatterplot.
Is it a positive or negative slope?
What is -1/2; negative.
Is the following function linear?
x 2 4 6 8 10
y 2 2 2 2 2
What is yes, it is linear because the rate of change is the same for the x-values and the y-values.
