6 because 4 tripled is 12 . And subtract 2 each day . It will take six days until you get zero

D1: 3(4) - 2 = 10
D2: 10 - 2 = 8
D3: 8 - 2 = 6
D4: 6 - 2 = 4
D5: 4 - 2 = 2
D6: 2 - 2 = 0

So it would be 6 days until you reach zero. Another way you could do it is 12 divided by 2.

Hope I helped :)

Answer:

D.) 1 + 1 + 5/8 + 2/8

Step-by-step explanation:

1 5/8 + 1 1/4

*set aside ones for a sec*

1/4 x 2/2 = 2/8

5/8 + 2/8

*get the ones back in*

1 + 1 + 5/8 + 2/8

Find the equation of the line between the points (10, – 5) and ( - 2,0).

Natali5045456 [20]

Answer (assuming it can be in slope-intercept form):

$y = -\frac{5}{12} x-\frac{5}{6}$

Step-by-step explanation:

1) First, find the slope of the line between the two points by using the slope formula, $m = \frac{y_2-y_1}{x_2-x_1}$ . Substitute the x and y values of the given points into the formula and solve:

$m = \frac{(0)-(-5)}{(-2)-(10)} \\m = \frac{0+5}{-2-10} \\m=\frac{5}{-12}$

Thus, the slope of the line is $-\frac{5}{12}$ .

2) Next, use the point-slope formula $y-y_1 = m (x-x_1)$ to write the equation of the line in point-slope form. Substitute values for $m$ , $x_1$ , and $y_1$ in the formula.

Since $m$ represents the slope, substitute $-\frac{5}{12}$ in its place. Since $x_1$ and $y_1$ represent the x and y values of one point the line intersects, choose any of the given points (it doesn't matter which one, it will equal the same thing) and substitute its x and y values into the formula as well. (I chose (-2,0), as seen below.) Then, isolate y and expand the right side in the resulting equation to find the equation of the line in slope-intercept form:

$y-(0)=-\frac{5}{12} (x-(-2))\\y-0 = -\frac{5}{12} (x+2)\\y = -\frac{5}{12} x-\frac{5}{6}$

Answer:

3602

Step-by-step explanation:

Formula = Population after n years = 2000( 1.04)^n

15 years the population will be 2000(1.04)^15
