(x+3)2 = x2+6x+9

(x+2)2 = x2+4x+4

(x-1)2 = x2-2x+1

Answer:10%= 310

5%= 155

15%=465

Step-by-step explanation: Solution for what is 15% of 3100

3100/x=100/15

(3100/x)*x=(100/15)*x - we multiply both sides of the equation by x

3100=6.66666666667*x - we divide both sides of the equation by (6.66666666667) to get x

3100/6.66666666667=x

465=x

x=465

<u>Let the number be x, and we have equation:</u>

16x + 2 = -7x - 21
16x + 7x = - 21 - 2
23x = - 23
x = -1

The number is -1

Which exponential function is represented by the values in the table?

svlad2 [7]

Here we use the equation

$y = a(b)^x$

Taking points (0,4), (1,2)

Substituting the point (0,4) , we will get

$4 = a(b)^0
\\
4 = a(1) \\
a =4$

Substituting (1,2) we will get

$2 = 4 (b)^1
\\
2/4 = b
\\
b = 1/2$

So we have

$a = 4, b = 1/2$

Therefore , required equation is

$y = 4(1/2)^x$
