Answer:
4. x= 18
Step-by-step explanation:
We solve the problem like this:
Since 3 is proportional to 6 and 9 is proportional to x, we set up a proportion.
3/9 = 6/x
We then use cross-multiplication to solve for x.
Expand the following:
(x - 6) (3 x^2 + 10 x - 1)
Hint: | Multiply out (x - 6) (3 x^2 + 10 x - 1).
| | | | x | - | 6
| | 3 x^2 | + | 10 x | - | 1
| | | | -x | + | 6
| | 10 x^2 | - | 60 x | + | 0
3 x^3 | - | 18 x^2 | + | 0 x | + | 0
3 x^3 | - | 8 x^2 | - | 61 x | + | 6:
Answer: 3 x^3 - 8 x^2 - 61 x + 6 Thus B:
Find the prices per ounce by dividing the dollars by the number of ounces:-
1.79 / 15 = 0.1193 dollars per ounce
1.49 / 12 = 0.1242 dollars per ounce
So the first one is the better buy.
Answer:
D
Step-by-step explanation:
To determine the scale factor calculate the ratio of corresponding sides, image to original, that is
= 
= 8 → D
<span>f(x+5/4) means that f(x) is translated 5/4 units left.
f(x-5/4) means that f(x) is translated 5/4 units right.
f(x)-5/4 means that f(x) is translated 5/4 units down.
f(x)+5/4 means that f(x) is translated 5/4 units up.
f(x*5/4) means that f(x) is compressed by a factor of 5/4.
f(x/5/4) means that f(x) is stretched by a factor of 5/4.</span>
