Answer:

y=2.5*10^9(0.005^{12 0}) \\\\

Step-by-step explanation:

The above question is in the form of an exponential decay. The equation for an exponential decay is given by:

y=ab^x

where y and x are variables, b < 1, a is the initial value of y (that is the value of y when x = 0).

Let y represent the number of trees left and x represent the number of months. Given that there is currently 2.5 billion trees, therefore a = 2.5 * 10⁹, b = 0.5% = 0.005. The equations becomes:

y=2.5*10^9(0.005^x)\\\\After\ ten\ years(x=10*12\ months=120\ months):\\\\y=2.5*10^9(0.005^{12 0}) \\\\

4(4x+3)=19x+9-3x+3 what are the steps
TEA [102]
Ok so:

4(4x+3) = 19x + 9 - 3x +3
parenthesis first:
4 x 4x = 16x    then    4 x 3 = 12

16x + 12 = 19x + 9 - 3x + 3
combine :) :
19x - 3x = 16x   then    9 + 3 = 12

16x + 12 = 16x +12
       -12             -12
16x = 16x
They are the same equations lol they equal 0.

Is y = 1/x linear or non linear
Fofino [41]

Answer: This answer is non-linear.

Step-by-step explanation:

The problem y=\frac{1}{x}  has Vertical Asymptotes,

Horizontal Asymptotes,

and No Oblique Asymptotes making, y=0  and x=0.

A linear function is a form of y=mx+b.

This answer would be <u>non-linear</u>

.<br> Evaluate ƒ(x) = 3x + 8 for x = 1.<br><br><br> 3<br><br><br> 5<br><br><br> 11<br><br><br> –11
rodikova [14]

Answer:

11

Step-by-step explanation:

Replace the variable xx with −1-1 in the expression.

f(−1)=−3⋅−1+8f(-1)=-3⋅-1+8

Simplify the result.

Tap for fewer steps...

Multiply −3-3 by −1-1.

f(−1)=3+8f(-1)=3+8

Add 33 and 88.

f(−1)=11f(-1)=11

The final answer is 1111.

=11
