Answer:
C
Step-by-step explanation:
L=2w-3
w(2w-3)=54
2w²- 3w-54=0
A= 2 , B= -3, C= -54
sub values into quadratic formula
i attached picture of formula
Final answer: you will be given 2 answers 6 and -4.5. -4.5 is rejected since a negative value cannot represent length because that just doesn't make sense.
w=6
Check:
L=2w-3
=2(6)-3
=12-3
=9
9*6=54
Therefore the dimensions of the photograph are 6 cm by 9 cm
<h3>Answer:</h3>
D
<h3>Explanation:</h3>
The graph of |x| opens upward. Your graph is vertically stretched by a factor of 3 and translated downward 1 unit.
Graphs B and D open upward, but only graph D is translated downward (not upward, as in B).
Answer:
You use the vertical line test to see if a function is relation is a function
Step-by-step explanation:
A function is a relation with only one output for every input. That means that if the x value and two y values, it is not a function.
For this case we can rewrite the expressions as:

That is, we run the decimal three times to the left.

That is, we run the decimal six times to the left.
So:

So, we have that
