Answer: 2x-9y=1
Step-by-step explanation:
(this is how i found it don't know if this is how you learned it though)
Subtract 20 from both sides of -3x-8y=20, so that it becomes -3x-8y-20
Subtract 19 from both sides of -5x+y=19, so you get -5x+y-19
Subtract like terms from both equations (-3x-8y-20)-(-5x+y-19), which gives you 2x-9y-1
-3--5=2, -8-1=-9, -20--19=-1
Add 1 to both sides and you get 2x-9y=1

using the quadratic formula
1) 6a²x² - 7abx - 3b²=0, a is not equal to zero
pls answer
Answers
Answer:
b = b2-4ac
= (-7ab)^2 -4 (6a^2)(-3b^2)
= 49a^2b^2 + 72a^2b^2
= 121a^2b^2
Now, x = (7ab +- root 121a^2b^2)÷2(6a²)
= (7ab +- 11ab ) ÷ 12a²
= ( 20ab)/12a² or 4ab/12a²
= 5/3ab or - 1/3ab .
So, these are its roots .

which equation represents a line that passes through 4 6) and is parallel to the line whose equation is 3x - 4y= 6
TIMED TEST WILL GIVE BRAINLIEST
Answers
Parallel means their slopes should equal to each other.
Thus we need to find the slope of the given line ,
Let's do it.....
[tex]3x - 4y = 6[/tex]
Subtract sides -3x
[tex] - 3x + 3x - 4y = - 3x + 6[/tex]
[tex] - 4y = - 3x + 6[/tex]
Divided sides by -4
[tex] \frac{ - 4}{ - 4}y = \frac{ - 3}{ - 4}x + \frac{6}{ - 4} \\ [/tex]
[tex]y = \frac{3}{4}x - \frac{3}{2} \\ [/tex]
This is the slope-intercept of the line.
We know that the coefficient of the x in slope-intercept form , is the slope of the line.
Thus the slope of the equation which we want is :
[tex]slope = \frac{3}{4} \\ [/tex]
_________________________________
We have following equation to find the point-slope form of the linear functions.
[tex]y - y(given \: point) = slope \times (x - x(g \: p) \: ) \\ [/tex]
Now just need to put the slope and the given point in the above equation.
[tex]y - 6 = \frac{3}{4} \times (x - 4) \\ [/tex]
Multiply sides by 4
[tex]4(y - 6) = 3(x - 4)[/tex]
[tex]4y - 24 = 3x - 12[/tex]
Plus sides 24
[tex]4y - 24 + 24 = 3x - 12 + 24[/tex]
[tex]4y = 3x + 12[/tex]
Subtract sides -3x
[tex]4y - 3x = 3x - 3x + 12[/tex]
[tex]4y - 3x = 12[/tex]
