Step-by-step explanation:
X=-3
Answer:
2/5
Step-by-step explanation:
We can find the slope using two points
(0,0) and (5,2)
m = (y2-y1)/(x2-x1)
= (2-0)/(5-0)
= 2/5
Subtract 2(first equation) from the second, and 3(first equation) from the third to eliminate <em>x</em> :
(2<em>x</em> + 3<em>y</em> + <em>z</em>) - 2(<em>x</em> + <em>y</em> + <em>z</em>) = 16 - 2*9
<em>y</em> - <em>z</em> = -2
(3<em>x</em> - 4<em>y</em> + 2<em>z</em>) - 3(<em>x</em> + <em>y</em> + <em>z</em>) = 1 - 3*9
-7<em>y</em> - <em>z</em> = -26
Now subtract either equation with <em>y</em> and <em>z</em> from the other to eliminate <em>z</em>. If we take the first from the second, we get
(-7<em>y</em> - <em>z</em>) - (<em>y</em> - <em>z</em>) = -26 - (-2)
-8<em>y</em> = -24
<em>y</em> = 3
Then
<em>y</em> - <em>z</em> = 3 - <em>z</em> = -2
<em>z</em> = 5
And lastly,
<em>x</em> + <em>y</em> + <em>z</em> = <em>x</em> + 3 + 5 = 9
<em>x</em> = 1
The approximate value of is 1.52832 or 1.53.
What is the logarithmic Expression?
A logarithmic expression is an function that involves the logarithm of an expression containing a variable. To solve exponential equations, first see whether you can write both sides of the equation as powers of the same number.
