Answer:
d. 18
Step-by-step explanation:
g(x)=3x-3
3(7)-3
21-3
=18
You can find the number of x intercepts by setting f(x) equal to zero giving you 0=x^4-5x^2. You can factor out an x^2 and divide on both sides (when you divide 0 by anything it is still zero so the x^2 disappears), and you are left with 0=x^2-5, which you can solve easily giving you x=+/- sqrt(5). However, the original equation also has an x intercept at (0,0) which you can see by plugging 0 in for x. So the grand total of x intercepts is 3!
Answer:
75%
Step-by-step explanation:
We can use the formula 
- "of" is 5
- "is" is 3.75
- We will denote "percent" as x since that is what we are solving for
Now we just need to plug in the known values and solve for x
- Cross multiplying we get (5)(x) = (3.75)(100)
- Then simplifying we get 5x = 375
- Dividing by 5 we get x = 75%
$3.75 is 75% of $5
