You’re going it plug in the inputs for every input for the letter x. So the first one, fx= -4(-2)+1= 9. The second one fx= -4(0)+1=1. The third one fx= -4(5)+1=19.

Solve each proportion.
Maslowich
To solve this question you need to cross multiply

So first do 3(2x+1) = 4(3x-2)
Which gives you 6x+1 = 12x-8

Now you solve it like a normal equation
6x+1 = 12x-8
9 = 6x
3/2 = x

What is the mean of the following set of data? Round your answer to two decimal places.
kolezko [41]
The mean is 73.44<span>

</span>
You could've found this by adding up all the values in the data set, then dividing by how many numbers were in the data set!

66+81+60+72+79+83+60+92+68 = 661

661 ÷ 9 = 73.44

Need help with this math problem ASAP. Look at the picture attached. The linear function f(x) passes through the points (0,3) an
Karo-lina-s [1.5K]

♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️

f(x) = 2x + 3

And

g(x) = 2 \times  {3}^{x}  \\

_________________________________

To find the y-intercept of any equation just need to put 0 (( zero )) instead of the x in the equation...

<h2>Let's do it....</h2>

_________________________________

In f ( x ) :

y - intercept = f(0)

f(x) = 2x + 3

f(0) = 2(0) + 3

f(0) = 3

Thus :

y - intercept = 3

##############################

In g ( x ) :

y - intercept = g(0)

g(x) = 2 \times  {3}^{x}

g(0) = 2 \times  {3}^{0}

g(0) = 2 \times 1

g(0) = 2

Thus :

y - intercept = 2

_________________________________

The positive difference in the y-intercept value of f ( x ) and g ( x ) is :

|3 - 2|  =  |1|  = 1

So write this in the box : 1

♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️

And we're done....
