Answer:
3 x^3 y^4 sqrt(5x)
Step-by-step explanation:
sqrt(45x^7y^8)
We know that sqrt(ab) = sqrt(a)sqrt(b)
sqrt(45)sqrt(x^7) sqrt(y^8)
sqrt(9*5) sqrt(x^2 *x^2 * x^2* x) sqrt(y^2 *y^2 *y^2 *y^2)
We know that sqrt(ab) = sqrt(a)sqrt(b)
sqrt(9)sqrt(5) sqrt(x^2)sqrt(x^2) sqrt(x^2) sqrt(x) sqrt(y^2)sqrt(y^2)sqrt(y^2)sqrt(y^2)
3 sqrt(5) x*x*x sqrt(x) y*y*y*y
3 x^3 y^4 sqrt(5)sqrt(x)
3 x^3 y^4 sqrt(5x)
Slope: -0.75, equation of the line:
Step-by-step explanation:
The equation of a line in the slope-intercept form is
where
m is the slope
are the coordinates of a point on the line
In this problem, we have:
We also know that the line has x-intercept at x = -6: so, it passes through the point
Using this information, we can find the slope of the line:
Therefore, the equation of the line is

Equation 1) -4x + 7y = 1
Equation 2) 25 = 2x + 5y
For both equations, move the variables all onto one side, preferably the left side.
To do so, for equation 2, subtract 2x from both sides, as well as subtracting 5y from both sides, and then subtracting 25 from both sides.
2) -2x - 5y = -25
1) -4x + 7y = 1
Multiply all of equation 2 by 2.
2) 2(-2x - 5y = -25)
2) -4x - 10y = -50
1) -4x + 7y = 1
Subtract the equations from each other.
-17y = -51
Divide both sides by -17.
y = 51/17
y = 3
Plug in 3 for y in the first equation.
-4x + 7y = 1
-4x + 7(3) = 1
-4x + 21 = 1
-4x = 1 - 21
-4x = -25
x = -25/-4
x = 25/4
x = 6 1/4
(6 1/4, 3)
