4x-11=3.2x+13. write the lesser solution first. round to the nearest tenth if needed

The answer is (30, 109)

Step-by-step explanation:

In this problem we need to find the intersection point between the lines

y = 4x-11

and

y = 3.2x+13

We can easily solve this problem by plotting both lines in a graphing calculator and finding the intersection point.

Please see attached picture.

The answer is (30, 109)

a4 - 3a2 - 1

step-by-step explanation:

step   1   :

equation at the end of step   1   :

  ((a4) -   3a2) -   1

step   2   :

trying to factor by splitting the middle term

2.1     factoring   a4-3a2-1  

the first term is,   a4   its coefficient is   1 .

the middle term is,   -3a2   its coefficient is   -3 .

the last term, "the constant", is   -1  

set each factor equal to 0

4x-3 = 0

2x-1 = 0

solve for x.

4x-3=0

4x=3

x= 3/4

solve for x. 

2x-1= 0

2x= 1

x= 1/2

eventually after a few more steps, your answer should be 1/2 is less than or equal to x and 3/4 is greater than or equal to x
