Multiply the equations to get the coefficients Greatest Common Factor:

3(2x+4y=11)

2(3x+6y=17)

6x+12y=33

6x+12y=34

Then you subtract them:

0x+0y=-1          0=-1

Or in other words no solutions

Factor completely x^4-17x^2+16​
Snowcat [4.5K]

Answer:

(x - 1) (x + 1) (x - 4) (x + 4)

Step-by-step explanation:

actor the following:

x^4 - 17 x^2 + 16

x^4 - 17 x^2 + 16 = (x^2)^2 - 17 x^2 + 16:

(x^2)^2 - 17 x^2 + 16

The factors of 16 that sum to -17 are -1 and -16. So, (x^2)^2 - 17 x^2 + 16 = (x^2 - 1) (x^2 - 16):

(x^2 - 1) (x^2 - 16)

x^2 - 16 = x^2 - 4^2:

(x^2 - 1) (x^2 - 4^2)

Factor the difference of two squares. x^2 - 4^2 = (x - 4) (x + 4):

(x - 4) (x + 4) (x^2 - 1)

x^2 - 1 = x^2 - 1^2:

(x^2 - 1^2) (x - 4) (x + 4)

Factor the difference of two squares. x^2 - 1^2 = (x - 1) (x + 1):

Answer: (x - 1) (x + 1) (x - 4) (x + 4)

How do you explain how you convert a decimal?
Troyanec [42]
For example if we have 7/10 we have one 0 in the denominator so we move the decimal spot 1 to the left

So:
7.0 becomes 0.70 or .7

To make a decimal into a fraction:

0.32

Just add two zeros to the right and that means 2 0's will be added in the denominator
so:

0.32
32.0/100 or 32/100

Hope that helps :)
