Answer:
Slope
Step-by-step explanation:
In the equation y = mx + b for a straight line, the number m is called the slope of the line. Definition 2. In the equation y = mx + b for a straight line, the. number b is called the y-intercept of the line.
The dependent variable is the one on the Y (vertical) axis
The independent variable is the one on the X (horizontal) axis
OH OH OH
i just remembered, in 6th or 7th grade, my science teacher gave us a way to remember which is which.
DRY MIX
DRY - Dependent (Responding) is on the Y axis
MIX - Manipulated (Independent) is on the X axis
Hope this helps!
Answer:
$312.50 is your new income.
Step-by-step explanation:
First, multiply 25% with 250. Change the percentage into a decimal.
25% = 25/100 = 0.25
Multiply 0.25 with 250:
250 x 0.25 = 62.5
Because the amount is being added (increase of income), add the amount found to the original amount:
250 + 62.5 = 312.5
$312.50 is your new income.

Answer:
Step-by-step explanation:
3.14159 is irrational because it's a repeating decimal; it cannot be expressed as the ratio of two integers. All the others can be expressed in that way.
Answer: Choice D) 1 - sec^2(a) = tan^2(a) is not an identity.
================================================
Explanation:
a) is the pythagorean trig identity assuming you meant to write sin^2(a)+cos^2(a) = 1
b) is a rewritten version of tan = sin/cos. You multiply both sides by cos(a).
c) is an identity that you can find through dividing everything in equation (a) by sin^2. I'm assuming you meant to put exponent symbols before each "2".
d) is not an identity. I recommend looking at a table or graph that compares the two sides as separate functions. You should see they are not the same. The actual identity should be sec^2(a) - 1 = tan^2(a). You divide both sides of equation (a) by cos^2 and do a bit of algebra to get it into this form.
