Answer:
4 + 36x is your expression
Step-by-step explanation:
4 x 1 = 4
4 x 9x = 36x
so 4 + 36x is your expression because you can't add numbers with different variables or if they don't even have one.
Answer:
the scatter plots shows a positive association.
Answer:
Step-by-step explanation:
Set up equation
Step 1: Simplify
Step 2:Multiply by conjugate
Step 3:Simplify
We can reduce this and we must make the imaginary number and real number serpate equations.
Reduce each by 2
Answer:
Slope: 3 Y-intercept: 6
Step-by-step explanation:
You want to put this equation into y=mx+b form so it's easier to tell.
Add 3x on both sides.
y = 3x + 6
The slope is always the coefficient (number) in front of the x in the y = mx + b form. 6 is the y-intercept (reason: the y-intercept is when x=0, and when you substitute 0 for x in this, you get y=6).
