I don’t know what you mean but i’m guessing you’re saying like, ex: 4x+9=3x-3 or something. in that situation we would do something my algebra 1 teacher would call the magic tunnel. step 1: move the 3x over and flip the sign (make it -3x because we’re going across the sign!) step 2: move the +9 over to the other side and flip the sign (make it -9!) your new problem would be 4x-3x=-3-9. step 3: do the math on each side of the equal sign (4x-3x=x), (-3-9=-12) therefore you now have your answer x=-12.

Answer:

If there are no variables left, then i guess u just have to write the rest down(constant, coefficient, etc...)

Solve the following equation for q. 8q + 4p + 4 = 4q – 8.

marishachu [46]

Answer:

a. q= -p - 3

Step-by-step explanation:

8q+ 4p + 4= 4q - 8

8q (- 8q) + 4p + 4 = 4q (-8q) -8

4p +4 = -4q -8

4p + 4 (+8) = -4q -8 (+8)

4p + 12 = -4q

(4p + 12)/-4 = (-4q)/-4

-p -3 = q

N(t) = 25t + 150 for 0<=t<6, (200 + 80t)/(2 + 0.05t) for t>=8

nadezda [96]

Answer:

1600. This is a maximum limit of fish the pond can host.

Step-by-step explanation:

For $\lim_{t \to \infty} N(t)$ , we must take the part of this function valid for high values, i.e., the second part, where $t \geq 8\\$ .

$\lim_{t \to \infty} N(t)=\lim_{t \to \infty} \frac{200+80t}{2+0.05t}$

Since we have two polynoms both in numerator and denominator, and both of them are of degree 1 (both linear), for high values of $t$ , the main part of each polynom shall be the linear part, neglecting lower degree parts (in this case, constant terms):

$\lim_{t \to \infty} \frac{200+80t}{2+0.05t}=\lim_{t \to \infty} \frac{80t}{0.05t}=\frac{80}{0.05} = 1600$

This means that the number of fish in a pond has an horizontal asymthote. In other words, there seems to be a natural limit for the number of fish that there will be in the pond as years pass. The maximum number of fish is actually 1600. With this function, no higher than this figure can be reached. This might imply limits in productivity.

14/9 as a mixed number

Gennadij [26K]

14/9 as a mixed number is 1 5/9 because you have to divide the the numerator by the denominator and you would get 1 and 5 left over
