Find the equation of the line in slope-intercept form.<br> m=− 4 7 through (14, 3
kakasveta [241]

Answer:

The answer to your question is:   y = -47x + 661

Step-by-step explanation:

Data

m = - 47         I wasn't sure if the slope was -47 or -4.

Point (14, 3)

Formula

(y - y1) = m(x - x1)

Process

                  (y - 3) = -47(x - 14)

                   y - 3 = -47x + 658

                   y = -47x + 658 + 3

                   y = -47x + 661

serg [7]

Answer:

options 3 and 6

Step-by-step explanation:

the exponent x+2 means that the graph moves to the left 2 units and the value of K, which is -4, means that the graph will then move down 4 units from the parent function f(x)

If the world's population increased exponentially from billion in 1998 to billion in 2008 and continued to increase at the same
Gelneren [198K]

Answer:

The answer is "7.122 billion"

Step-by-step explanation:

Please find the complete question in the attached file.

Using formula:

\to y=Ce^{kt}  

C=5.937\\\\y=6.771\\\\t=10\\\\ k=?6.771=5.937e^{10k}\\\\1.1405=e^{10k}\\\\\ln(1.1405)={10\ k}\\\\0.013={k}\\\\

So,  

\to y=5.937e^{.013t}\\\\

when it becomes 2012, \ t=14 so plug the value into the formula  

\to y= 5.937e^{.013(14)} =7.122 \ billion

What is the value of f(-4) in the piecewise function f(x)= -x-5 for -5&lt;= x &lt;= -2; -x^2+1 for -2&lt;=x&lt;=2; (x-3)^2+2 for
Alik [6]


We first need to pick the correct piece to use. In this case, we will use f(x) = -x-5 because -5<=-4.

Then, we use direct substitution:
f(-4) = -(-4) - 5
f(-4) = -1
