Using the equation N=4,599(2)^t and the number 6 as t, we get N=4,599(2)^6.

(2)^6 = 64

4,599 x 64 = 294,336

What are the solutions to the following system of equations?<br> y = x2 + 12x + 30<br> 8x – y = 10
atroni [7]
We are given with two solutions: y = x2 + 12x + 30 and 8x – y = 10 and is asked to determinte the solutions of the system of equations. We get y in the second eqn which is equal to 8x -10. we substitute this to first eqn resulting to 
8x-10 = x^2 + 12 x + 30. this is a second order equation. x is equal to -2 + 6i and -2 - 6i.

Write in slope-intercept form an equation of the line that passes through the points (−15,−1) and (10,4).
grin007 [14]

Answer:

y =  \frac{1}{5} x + 2

Step-by-step explanation:

<u>Slope-intercept </u><u>form</u>

y= mx +c, where m is the slope and c is the y-intercept.

\boxed{slope =  \frac{y1 - y2}{x1 - x2} }

Slope

=  \frac{4 - ( - 1)}{10 - ( - 15)}

=  \frac{4 + 1}{10 + 15}

=  \frac{5}{25}

=  \frac{1}{5}

Substitute m= ⅕ into the equation:

y= ⅕x +c

To find the value of c, substitute a pair of coordinates.

When x= 10, y= 4,

4= ⅕(10) +c

4= 2 +c

c= 4 -2

c= 2

Thus, the equation of the line is y= ⅕x +2.
