no it should be multiplied not added.
Evaluate: (2^2)^3
4^3 = 64 or 2^6 = 64
What form do we use to graph a linear equation?
The slope-intercept form y = mx + b

0.0095
Simplify: (x^5)
(x^9)
x^14
graph the following equation.Include at least 3 points. y = 1/3x + 4
Graph should start with the point at (0,4) Movement should be 1 up and 3 to the right continuing to another point . Movement could also be 1 down and 3 to the left.
true or false: irrational numbers are not useful because we cannot write them as fractions.
false
what is a equation between two variables that gives a straight line when plotted on a graph
Linear equations
The size of the Sahara desert is about 3.629 * 10^6 square miles and the Arabian desert is about 9 * 10^5 square miles. Which desert is larger? Explain how you know.
Sahara, because the exponent is bigger
Simplify: (36x^4y^3)/(6xy^2)
6x^3y
Graph the following equation. Include at least three points. y = -2
Graph should begin with a point on the y-axis at -2. A horizontal line should be drawn through -2 extending on both sides of the y-axis
Is -7000.02525 irrational.
no
What is the term used for expressing numbers that are too large or too small to be conveniently written in decimal form.
Scientific notation
The size of the four oceans, in square km, is shown below. List the oceans from smallest to largest. Pacific Ocean _1.7965 * 10^8, Arctic Ocean - 1.323 * 10^7, Atlantic Ocean - 1.061 * 10^6, Indian Ocean - 7.49 * 10^7
Arctic,Indian,Atlantic,Pacific
Simplify: (5x^2)^3/(7y^9)^0
125x^6
Make a table of values with at least 4 ordered pairs for the following equation. y = 1/2x -5 Then plot the ordered pairs. Draw a line through the points.
table should list four numbers chosen for x and then solved by multipling by 1/2 and subtracting . If x is 2 then If x is 4 then 1/2(2) = 1 - 5 1/2(4) = 2-5 then 7 = -4 then y = -3
do irrational numbers terminate
no
