Write an equation that passes through (4,-3) and is perpendicular to y=-2x-4

Mathematics

The point is (4,-3) and is perpendicular to y=-2x-4.

The slope is given , m=-2.

For the perpendicular line, the slope is

m_1\times m_2=-1m_1\times-2=-1m_1=\frac{1}{2}

Now, then the general equation is

y-y_1=m(x-x_1)

Substitute the values.

y-(-3)=\frac{1}{2}(x-4)y+3=\frac{1}{2}(x-4)y=\frac{1}{2}x-\frac{4}{2}-3y=\frac{1}{2}x-2-3y=\frac{1}{2}x-5

Hence the equation is determined as

y=\frac{1}{2}x-5

CAN SOMEONE HELP ME PLEASE ASAP!?
Andrews [41]

Answer: 69

Step-by-step explanation:

The two angles are a linear pair, which means that they lie on the same line. Therefore, you just have to substract angle 1 with 180.

180-111=69

An electric utility company determines the monthly bill for a residential customer by adding an energy charge of 6.34 cents per
kirill [66]

Answer:

y = 18.38 + 0.0634x

Step-by-step explanation:

Given,

Monthly base charge = $18.38,

Also, the cost of each kilowatt-hours = 6.34 cents = $ 0.0634

( 1 cents = 0.01 dollars ),

So, the cost of x kilowatt-hours = 0.0634x,

If y represents the total monthly charge ( in dollars ) for x kilowatt-hours,

Thus, the total monthly charge for x kilowatt-hours = base charge + cost of x kilowatt-hours,

⇒ y = 18.38 + 0.0634x

Which is the required equation.
