Answer:
4.5 hours
Step-by-step explanation:
divide miles by speed
Population growth is generally given by an exponential function,
<em>f</em>(<em>x</em>) = <em>a</em>*<em>b</em>^<em>x</em>, where <em>a</em> is the original population, <em>b</em> = 1 + the rate of growth (written as a decimal number), and <em>x</em> is the amount of time. In our case we have
<em>p</em>(1 + 0.065)<em>^</em>1<em>
</em>= <em>p</em>(1.065) = 1.065<em>p</em>
next number would be 89, because you add the number before to get the next,
8 + 5 = 13 + 8 = 21 + 13 = 34 + 21 = 34 + 21 = 55 + 34 = 89
final answer: 89
I’m not the best with words but first you would have to treat the greater sign as a = sign. So..
-2x =6
/ /
-2 -2
X = -3
and then you would change the sign to a less than sign because you divided by a negative.
The x-intercept is the value of x when y is equal is zero. It is the point in the x-axis intersected by the line. The y-intercept is the value of y when x is zero. It is where the line intersects in the axis. Therefore, for the given equation:
<span>y=−12x+4
</span><span>y=−12(0)+4 = 4<--------y-intercept
</span><span>0=−12x+4
x = 1/3 <--------x-intercept</span>
