Solve for x with steps.

Mathematics
1 answer:
kiruha [24]3 years ago
8 0

Answer:

no real solution is the answer

If you have to list your extraneous solutions somewhere, that would be x=0.

Step-by-step explanation:

Cool thing here is the radical, the thing with the square root, is already isolate.

So we need to square both sides as a first step.  (Whenever you raise both sides to even power, you must definitely check your solutions as some might not actually be solutions to the original equation)

So upon squaring both sides I get:

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

Now I will write (x^2-4)^2 as (x^2-4)(x^2-4) and foil it!  This gives me:

x^4+16=x^4-8x^2+16

Subtract x^4 and 16 on both sides:

       0=-8x^2

Divide both sides by -8

      0=x^2

Therefore x=0.

0 isn't actually a solution though because when you plug it in you get 4=-4 which is not true.

What expressions represent 1/3 times the sum of 8 and 4
san4es73 [151]

Answer:

1/3 * (8 + 4)

Step-by-step explanation:

Expression which represents 1/3 tines the sum of 8 and 4

Expressing mathematically,

Sum of 8 and 4 is written as (8 + 4)

1/3 of the sum is expressed as ; 1/3 x (8 + 4)

Hence,

1/3 * (8 + 4)

1/3 * 12

= 4

Expression is 1/3 * (8 + 4)

Result = 4

The sum of 2 numbers is 44 the smaller number is 16 less than the larger number what are the numbers
Anon25 [30]
X=27 and y=11
if you let each number equal x and y we know the sum is 38 so x+y=38
and the smaller is 16 less than the larger
. so if we say the smaller number is 7 then x-16=y
these can be solved as a simultaneous equation. x+(x-16)=38
2x-16=38
2x=54
x=27
(27)-16=y
y=11
so the answer is x=27 y=11

12.) m=26
19-(-7)/-1-(-2)=26

13.) 14
8-(-20)/5-3=14

14.) -4/5 is the slope
Count rise over run and always make sure whether to add a negative based on the direction of the line. In this situation, the line is negative so there is a negative sign present.
