Answer:

80 copies

Step-by-step explanation:

4 minutes= 240 seconds. So I did 240 seconds divided by 3 seconds (one copy is made in that time) then you get 80. I don't know if that explanation make sense but the math checks out.

Answer:

$y = - \frac{1}{4} x - 10$

Step-by-step explanation:

The negative reciprocal of 4 is -1/4.

Let's substitute in our values, to find the y-intercept:

$y = - \frac{1}{4} x + c$

$- 11 = - 1 + c$

$c = - 10$

Finally, our full equation is:

$y = - \frac{1}{4} x - 10$

Answer:

$\displaystyle x=\frac{-8\pm\sqrt{(8)^2-4(4)(-221)}}{2(4)}\ \text{; x = 6.5 and x = -8.5}$

Step-by-step explanation:

Subtract the right side of the given equation to put it into standard form:

4x² +8x -221 = 0

Then the coefficients used in the quadratic formula are ...

a = 4
b = 8
c = -221

When these are filled into the form ...

$\displaystyle x=\frac{-b\pm\sqrt{b^2-4ac}}{2a}$

the result is as shown above.
