What is the slope of the line? NEED ASAP WILL MAKE BRAINLIEST
Brrunno [24]

Answer:

2

Step-by-step explanation:

To find the slope, we  use the equation

m = (y2-y1)/(x2-x1)

Since the have the points (2,-4) and (4,0)

m = (0--4)/ (4-2)

   = (0+4)/(4-2)

   = 4/2

   =2

Simplify the following expression completely, where x is greater than or equal too 0.
Dennis_Churaev [7]
First you want the numbers under the radical to be the same so you can combine like terms.

x \sqrt{5xy^4} =x \sqrt{5x*^4y} = xy^2 \sqrt{5x}
\sqrt{405x^3y^4} =  \sqrt{5x*81x^2y^4} =9xy^2 \sqrt{5x}
\sqrt{80x^3y^4} =  \sqrt{5x*16x^2y^4} = 4xy^2 \sqrt{5x}

Now add together to get 14xy^2 \sqrt{5x}

Finger [1]

Answer:

see explanation

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

Given

- 4x + 3y = 12 ( add 4x to both sides )

3y = 4x + 12 ( divide the terms by 3 )

y = \frac{4}{3} x + 4 ← in slope- intercept form

with slope m = \frac{4}{3} and y- intercept c = 4

---------------------------------------------------

Given

- 5x + 3y = - 9 ( add 5x to both sides )

3y = 5x - 9 ( divide the terms by 3 )

y = \frac{5}{3} x - 3 ← in slope- intercept form

with slope m = \frac{5}{3} and y- intercept c = - 3

A line passes through (-7,-5) and (-5,4). Write an equation for the line in point-slope form. Rewrite the equation in standard f
rewona [7]
The equation:
y - y 1 =  ( y2 - y1 ) / ( x2- x1) * ( x - x1 )
y - ( - 5 ) = ( 4 + 5 ) / ( - 5 + 7 ) * ( x - ( - 7 ) )
y + 5 = 9/2 ( x + 7 )
y + 5 = 9/2 x + 63 /2  / * 2
2 y + 10 = 9 x + 63
- 9 x + 2 x = 53
Answer:
C ) y + 5 = 9/2 ( x + 7 ) ;   - 9 x + 2 y = 53
