Which expression shows they are not the same
The expression that shows this is:
Take for instance; y=2
Substitute 2 for y in
Evaluate all exponents
The above expression supports
The answer to this is step 2 because they multiplied when they should of subtracted the 10 and the 12.
Answer:
8/9
Step-by-step explanation:
10-2/10-1=8/9
slope=8/9
Answer:
Step-by-step explanation:
probability ∈[0,1]
or probability ≥0
and ≤1
so a,b,g cannot be the probability of an event.
2x+3y= 12
To solve for the x intercept, y=0
2x+3(0)= 12
2x= 12
Divide both sides by 2
2x/2x= 12/2x
X= 6
So:(6,0)
To solve for y intercept, x=0
2(0)+3y= 12
3y= 12
Divide both sides by 3
3y/3y= 12/3
Y= 4
So: (0,4)
