Answer:
y = x + 4
Step-by-step explanation:
To find the constant in the equation, look in the table for the value of y when x=0. That value is 4, so ...
y = x + 4
That would be B because 65 < 40 + 30
Answer:
C
Step-by-step explanation:
We need to use the distributive property to expand this.
The property is:
a(b+c) = ab + ac
So, the part " -3(2b+1) " will becomes:
-3(2b+1) = (-3)(2b) + (-3)(1) = -6b - 3
So, the problem becomes:
-2b -3(2b+1) = -2b -6b -3
Now, we add like terms:
-2b - 6b - 3
(-2-6)b - 3
-8b - 3
This is the correct answer, answer choice C
what do pre and post test studies look at?data collected on the same sample elements before and after some experiment is performedwhen are the t procedures exactly correct?when the pop is exactly Normal (rare)the t procedures are robust to small deviations from Normality, butthe sample must be a random sample from the pop
First, you make 9 into a fraction which would become 36/4
then, subtract 9/4 from both sides so that would give you 3/4x = 27/4
then divide each side by 3/4 (same thing as multiply by its reciprocal) and that would give you x=9
