Simplify. Combine like terms.
7 - 9 = -2
4t - 2 = -6 + 6t
Isolate the t. Note the equal sign. Add 2 to both sides, and subtract 6t from both sides
4t (-6t) - 2 (+2) = -6 (+2) + 6t (-6t)
4t - 6t = -6 + 2
Simplify
-2t = - 4
Isolate the t, divide - 2 from both sides
-2t/-2 = -4/-2
t = -4/-2
t = 2
t = 2 is your answer
hope this helps

Answer:
yes
Step-by-step explanation:
There are several ways to go at this.
My first choice is to use a graphing calculator. It shows the function has a zero at x=5, so x-5 is a factor.
Another good choice is to use synthetic division (2nd attachment). If the remainder is zero, then x-5 is a factor. It is and it is.

You can also evaluate the function at x=5. The remainder theorem tells you that if the value is zero, then x-5 is a factor. Evaluating the polynomial written in Horner form is a lot like synthetic division.
(((x -4)x -15)x +58)x -40 for x=5 is ... (-10·5 +58)5 -40 = 40-40 = 0
The value of h(5) is zero, so x-5 is a factor of h(x).
399,499.
Since we are rounding to the nearest thousand, we are going to be focusing on mainly 39(9,499). The rule I learned is, "5 or above, give it a shove". Since it isn't 500 or above, we have to round it down to 9,000.
The total is 399,000.
