I have to go see my dog in the hospital today
The total cost for plumber number 1 expressed as a function of x is
c1(x)=45x+90
That is, the charge per hour times the number of hours plus the fixed charge for a visit.
Using the same pattern, write the function for the second plumber. Then set the two functions equal to each other and solve for
Answer:
X=15
Step-by-step explanation:
Yes, you are right.
The given equation is
X+U=25
If U=10, then we substitute to obtain:
X+10=25
Subtract 10 from both sides to get:
X=25-10
Simplify to get:
X=15
Answer:
<em>The answer would be 8x + 24</em>. And it's not a trinomial form. Why? Maybe the given is not just (3+5), it's (3x+5). So that we can get trinomial product.
Sol.
(x + 3) (3x + 5)
Each parenthesis has a binomial (two numbers)
A. Note that whenever you have two parenthesis next to each other like this, it implies factoring. So let's factor.
3x^2 + 5x + 9x + 15
We get a quartnomial (containing 4 numbers), but we're looking for a trinomial. Can we reduce this?
B. Yeah, so we reduce
3x^2 + 14x + 15
There you go, this is a trinomial.
34 as a fraction is 17/50
-7 as a fraction is 8/20
