What does the equation -9+|m-8|<0 equal to?

UNO [17]

The equation $-9+|m-8|$ equals to $-1 < m < 17$

Step-by-step explanation:

We need to solve the equation:

$-9+|m-8|$

Solving:

Adding 9 on both sides

$-9+9+|m-8|$

Applying absolute rule: |u| < a and a > 0 then, -a < u < a

So, $-9 < m-8 < 9$

Now we have,

m-8>-9 and m-8 <9

m>-9+8 and m <9+8

m>-1 and m<17

Combining the intervals:

-1 < m < 17

So the equation $-9+|m-8|$ equals to $-1 < m < 17$

Solve the system of equations

Solnce55 [7]

Hey, there!!

Given that:

y = 3x.........(i)

$y = {x}^{2} + 3x - 16.......(ii)$

Putting the value of y in equation (ii)

${3x}^{} = {x}^{2} + 3x - 16$

${x }^{2} - 16$ =0

$( {x)}^{2} - {4}^{2} = 0$

$(x + 4)(x - 4) = 0$

Therefore,

Either Or

(x+4)=0 (x-4)=0

x= -4 x= 4

so, x= (+ -)4

And if you wanna get value of y, just keep value of x in equation (i).

y= 3x

y= (3×4) or (3×-4)

y= 12 or -12

{As it is the quadratic equation it has two values. }

Hope it helps....
