Answer:

So you have the multiplication and substitution right. It's just the subtraction.

Step-by-step explanation:

Now, the equation was y = 4x - 2

In the first one x = -3

So it will be 4(-3) - 2

Note: Anytime you see a bracket it means multiplication.

4× -3 = -12 and

-12 - 2 = -14

This is because a negative number minus another number is always negative.

And when dealing with negative numbers you add them but you negate the answer.

For example;

The second one will be -8 - 2

And 8 + 2 = 10

But since the numbers are negative we just negate the 10 making it - 10.

I hope this helps

What is the value of x in the equation below?

belka [17]

$remember$
$ln(a^b)=bln(a)$
$ln(e)=1$
$so$
$ln(e^x)=xln(e)=x$

$1+2e^{x+1}=9$
$minus \space\ 1 \space\ both \space\ sides$
$2e^{x+1}=8$
$divide \space\ both \space\ sides \space\ by \space\ 2$
$e^{x+1}=4$
$take \space\ ln \space\ of \space\ both \space\ sides$
$ln(e^{x+1})=ln(4)$
$(x+1)ln(e)=ln(4)$
$x+1=ln(4)$
$minus \space\ 1 \space\ from \space\ both \space\ sides$
$x=ln(4)-1$
$answer \space\ is \space\ C=ln(4)-1$
