-4/3x-6=-26 <br><br>A. -27<br>B. -15<br>C. 15<br>D. 27
JulsSmile [24]

Answer:

C. 15

Step-by-step explanation:

-4/3x-6=-26


The first step is to add 6 to each side

-4/3x-6+6=-26+6

-4/3x =-20  

Now multiply by -3/4 to isolate x.

-3/4 * -4/3x = -3/4 * -20

x = 60/4

x = 15

How to graph an exponential function
irina1246 [14]

Step-by-step explanation:

Exponential function is given by general form y=ab^x

Where a and b are constants.

say a=1 and b=2 then we can write function as :

y=1*2^x

or y=2^x

To graph this or any exponential function, we just need to find some points then join them by a curved line.

Like plug x=0, 1, 2,... into above function and find points:

plug x=1

y=2^x=2^1=2

Hence point is (1,2)

Find more points similarly then graph them to get the graph as shown below:
