Answer:
<h2>y = 19.99x + 30</h2><h2 />
Step-by-step explanation:
one time charge of $30
plus $19.99 per hour
let x be the number of hour
and y be the total charge of the magician.
therefore, the equation would be:
y = 19.99x + 30
Answer: x=11
Step-by-step explanation:
Answer:

Step-by-step explanation:
This problem lays out pretty clearly what needs to be done.
First, we know that we are writing an inequality.
Then, it tells us that we need 'the product of x and 7'. A product is the result of multiplication, so we can multiply 7 and x together to get 7x.
Next, it tells us that the product (7x) is at least 15. At least means that the product has to greater than or equal to 15. That clue tells us which inequality symbol will be used.
Put it all together and:

Hope this helped!
The tax rate on a dollar would be .08% you have 4 dollars you have 32 cents tax 4 divided in to 32 is 8. So for each dollar you pay 8 cents.
Hello from MrBillDoesMath!
Answer: 6 u^2 + 4u + 6 = 0 where u = (x-5)^2
Discussion; I think the problem statement should actually be to rewrite <u>this</u> equation:
6 (x-5)^4 + 4 (x-5)^2 + 6 -= 0.
Note the power of "x-5" is 4 in the first term and is 2 in the second term. That is, the power of x-5 in the first terms is double, or the square, of the (x-5) power occurring in the second term. This suggest the substitution u = (x-5)^2. Then the equation can be rewritten as
6 u^2 + 4u + 6 = 0
which is a quadratic in "u".
