-2a-4>-8 please help
grandymaker [24]
Hey there!

Firstly, we have to “add” the number “4” on each of your sides

Like: -2a -4 + 4> -8 +4
Cancel: -4 + 4 because it will give you “0”
Keep: -8+4 because it gives you “-4” and we have paid it off with -2a

Like: -2a>-4

Divide each of the sides by “-2”

Like: -2a/2 > -4/-2

Cancel: -2a/2 because it gives us “1”

Keep: -4/-2 because that’ll give us the answer on the left side of the inequality

So, a < 2 would be your answer

Good luck on your assignment and enjoy your day

Choose the graph which matches the function. (2 points) <br> f(x) = 3x-1
ValentinkaMS [17]

Answer:

Observe the attached image

Step-by-step explanation:

We know that f(x) = 3^{x-1} is an exponential function, therefore its graph must have the form that corresponds to this type of functions.

The first thing to do is find the cut points of the function.

Cut point with the y axis:

x = 0\\\\y = 3^{0-1}\\\\y = 3^{-1}\\\\y = \frac{1}{3}

The function cuts the y-axis on y = \frac{1}{3}

Cutting point with the x axis:

y = 0\\\\0 = 3^{x-1}

To clear x we must apply log on both sides of the equality, but the log(0) is not defined. Then, the function does not cut to the x axis.


The graph that represents the function f(x) is the one that cuts in y = \frac{1}{3} and does not cut the x-axis

Jason’s credit card has an apr of 17.02% and a 30-day billling cycle. the following table details jason’s transactions with that
forsale [732]

The method of computing that would result in a greater finance charge is  a. the daily balance method will have a finance charge $1.02 greater than the adjusted balance method.

<h3>What is the Adjusted Balance Method?</h3>

This refers to the method of accounting that makes use of the owed amount of money at the end of a billing cycle to make its computation on an account after the credits are calculated.

Hence, we can see that when comparing the adjusted balance method to the daily balance method that calculates the interest charges at the end of the day, the daily balance method would have a higher finance charge.

Solve for x.<br> 3x-12y=27
coldgirl [10]

Answer: x=4y+9

Step-by-step explanation:

All of the variables, 3x, 12y, and 27 can be divided y 3, so we will simplify by dividing the whole equation by 3.

3x/3-12y/3=27/3

Which is equal to....

x-4y=9

Now you can move -4y over to the right side by changing its sign...

x=4y+9
