Answer:
A. A horizontal shift to the right 7.5 units
Step-by-step explanation:
Replacing x with x-7.5 shifts the graph 7.5 units to the <em>right</em>.
__
In general, g(x) = f(x-h)+k will shift h units right and k units up. In this problem there is no vertical shift.
Answer:
false
Step-by-step explanation:
the relationship between lengths/dimensions and areas is that areas are created by multiplying 2 dimensions.
when you quadruple (×4) the dimensions, then the areas are growing with the square of the factor (×4×4 = ×16), because the factor goes twice into the multiplication : one time for every dimension involved.
so, quadrupling the dimensions would multiply the areas by 16.
Answer: no.
Step-by-step explanation: In reaction Pb -> PbSO4 Pb is oxidised
Losing two electrons
The answer is -5
Explanation: Divide 2 to get rid of the top number. It looks like this
-10. 2y
___. ___
2. 2
What this does is remove the two from the Y and sets it by itself. Then you divide the -10, and the answer is -5
Answer:
Step-by-step explanation:
We have been given that n=-2 verified as a solution to the equation 
.
As n=-2 is the solution for our given equation, so it will satisfy our equation.
Let us substitute n=-2 is our given equation.
Since the value of n satisfies our equation, therefore, last line of the justification will be .
