Write an equation of a line in standard form, that is parallel to the line
Alex_Xolod [135]

Answer:

-2x+Y=12

Step-by-step explanation:

4x-2y=8

-4x -4x

-2y=-4x+8

-2 -2

Y= -4x/-2 + 8/-2

Y= 2x-4

M= 2

Y=mx+b

8=2 (-2) +b

8= -4+b

12=b

Y=2x+12

-2x -2x

-2x+Y=12

Which is the value of this expression when a=-2 and b=-3
Lerok [7]

Answer:

\frac{729}{64}

Step-by-step explanation:

The given expression is

(\frac{3a^{-3}b^{2}  }{2a^{-1} b^{0} } )^{2}

Where a=-2 and b=-3.

When we say "evaluate the expression" refers to replacing the given values in the expression. Then, we solve each power in the numerator and denominator. After that, we solve each product in the fraction. At the end, we apply the square power. As follows

(\frac{3a^{-3}b^{2}  }{2a^{-1} b^{0} } )^{2}=(\frac{3(-2)^{-3}(-3)^{2}  }{2(-2)^{-1} (-3)^{0} } )^{2}=(\frac{3(\frac{1}{-8})(9)}{2(\frac{1}{-2} (1))} )^{2} =(\frac{-\frac{27}{8} }{-1} )^{2} =\frac{27^{2} }{8^{2} } =\frac{729}{64}

Convert to standard form of the equation into the slope intercept form -3x-5y=-15
Mamont248 [21]
Our goal is to get y by itself
We will first add 3x to both sides to get
-5y = 3x - 15
We will then divide both sides by -5 to get y by itself which becomes
y = -3/5x + 3
