Measurement of "AC" :
(x + 5) + (2x <span>− 11) ;
________________________
Find the measurement of "AB" [which is: "(x+5)" ]:
______________________________________________
First, simplify to find the measurement of "AC" :
________________________________________
</span>(x + 5) + (2x − 11) ;
= (x + 5) + 1(2x − 11) ;
= x + 5 + 2x − 11 ;
→ Combine the "like terms" ;
x + 2x = 3x ;
5 − 11 = - 6 ;
______________
to get: 3x − 6 ;
_______________
So, (x + 5) + (2x − 11) = 3x − 6 ;
_______________________________
Solve for: "(x + 5)"
_______________________________
We have:
_______________________________
(x + 5) + (2x − 11) = 3x − 6 ;
Subtract: "(2x − 11)" ; from EACH SIDE of the equation ;
to isolate "(x + 5)" on one side of the equation;
and to solve for "(x + 5)" ;
________________________________________________________
→ (x + 5) + (2x − 11) − (2x − 11) = (3x − 6) − (2x − 11) ;
→ (x + 5) = (3x − 6) − (2x − 11) ;
_________________________________________________
Note: Simplify: "(3x − 6) − (2x − 11)" ;
→ (3x − 6) − (2x − 11) ;
= (3x − 6) − 1(2x − 11) ;
= 3x − 6 − 2x + 11 ;
__________________________
→ Combine the "like terms" :
_____________________________
+3x − 2x = 1x = x ;
-6 + 11 = 5 ;
_____________________________
To get: x + 5 ;
So we have:
______________________________
x + 5 = x + 5 ;
______________________________
So, x = all real numbers.
x = <span>ℝ </span>
First change 0.8 to a fraction which is 4/5. Then find a common denominator between 5/8, 4/5, and 3/5. The common denominator is 40. So then you multiply the numerator by the same number you multiply the denominator by. I'll do 5/8 as an example; to get 40 as your denominator multiply 8 by 5, and then multiply 5 by 5. The fraction you'll get is 25/40. The rest of the fractions are 4/5 - 32/40 and 3/5 - 24/40. Then order them either from smallest to largest (24/40, 25/40, 32/40) or largest to smallest (32/40, 25/40, 24/40).
The required x and y-intercept of the given line is -3 and -6/5 respectively.
<h3>What is the slope of the line?</h3>
The slope of the line is the tangent angle made by line with horizontal. i.e. m =tanx where x in degrees.
Here,
The given equation of the line is 2x+5y=-6.
Transform into standard form of line .i.e is y = mx + c
5y = -2x - 6
y = -2x/5 - 6/5
here , m = -2/5 and c = -6/5
Since c = y-intercept of the line = -6/5
Now, put y = 0 in the equation of the line.
2x = -6
x = -3
Thus, the required x and y-intercept of the given line is -3 and -6/5 respectively.
