What is an equation of the line that passes through the point (5, 4) and is parallel to

weqwewe [10]

Answer & Step-by-step explanation:

When two lines are parallel, their slopes are the same. To find the slope of the given equation, convert to slope-intercept form:

$y=mx+b\\\\$

m is the slope
b is the y-intercept, which is the value of y when the value of x is zero
x and y are the corresponding coordinate points (x,y)

$6x-5y=15$

Solve for y. Subtract 6x from both sides:

$6x-6x-5y=15-6x\\\\-5y=-6x+15$

Divide both sides by -5:

$\frac{-5y}{-5} =\frac{-6x}{-5} +\frac{15}{-5} \\\\y=\frac{6}{5}x-3$

The slope is $\frac{6}{5}$ .

Now you need to make an equation in point-slope form:

$y-y_{1}=m(x-x_{1})$

m is the slope
$x_{1}$ and $y_{1}$ are the coordinate points

Insert known values:

$y-4=\frac{6}{5}(x-5)$

You can use this equation, or you can convert to slope-intercept form by solving for y:

Use the distributive property:

$y-4=\frac{6}{5} x-6$

Add 4 to both sides:

$y-4+4=\frac{6}{5}x-6+4\\\\ y=\frac{6}{5}x-2$

(-3+2iroot48)(-5-4iroot12)

iVinArrow [24]

For this case we must simplify the following expression:

$(-3 + 2i \sqrt {48}) (- 5-4i \sqrt {12})$

Rewriting:

$(-3 + 2i \sqrt {4 ^ 2 * 3}) (- 5-4i \sqrt {2 ^ 2 * 3}) =\\(-3 + 2 * 4i \sqrt {3}) (- 5-4 * 2i \sqrt {3}) =\\(-3 + 8i \sqrt {3}) (- 5-8i \sqrt {3}) =$

We apply distributive property:

$- * - = +\\- * + = -\\15 + 24i \sqrt {3} -40i \sqrt {3} - (8i \sqrt {3}) ^ 2 =\\15 + 24i \sqrt {3} -40i \sqrt {3} -64i ^ 2 * 3 =$

We have to $i ^ 2 = -1$ :

$15 + 24i \sqrt {3} -40i \sqrt {3} + 192 =$

Adding similar terms:

$207-16i \sqrt {3}$

Answer:

$207-16i \sqrt {3}$

How to solve 5x+6=-4

IceJOKER [234]

Solve for x.
Minus 6 from both sides. I will look like this: 5x+6-6=-4-6. It now equals 5x=-10. Divide both sides by by 5. Now, x=-2
