What is the equation of a line that passes through the point (6, 1) and is perpendicular to the line whose equation is y=−2x−6 ?
ladessa [460]

Answer:

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

Step-by-step explanation:

we are given

Line is perpendicular to y=−2x−6

we can compare it with

y=mx+b

where

m is slope

so, m=-2

so, slope is -2

Our line is perpendicular to this slope

so, slope of our line will be

m'=-\frac{1}{-2}

m'=\frac{1}{2}

now, we are given point as (6,1)

so, x_1=6,y_1=1

now, we can use point slope form of line

y-y_1=m(x-x_1)

we can plug values

y-1=\frac{1}{2}(x-6)

now, we can solve for y

and we get

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

The scale of this map is 1 inch = 50 miles. The ruler measures the distance between Gary, Indiana, and Traverse City, Michigan,
levacccp [35]

Answer:

<em>150 miles</em>

Step-by-step explanation:

Given the scale on the map using the conversion factor

1 inch = 50 miles

We are to find the equivalent miles between the cities in miles if the distace is 3inches

3inches = x

Divide both expressions

1/3 = 50/x

Cross multiply

x = 3 * 50

x = 150

<em>Hence the actual distance between these two cities in miles is 150 miles </em>

Please simplify<br> 1,056=6(x+19)
bulgar [2K]

Answer: x = 157

Step-by-step explanation:

1056=6\left(x+19\right)

Switch sides:

6\left(x+19\right)=1056

Divide both sides by 6:

\frac{6\left(x+19\right)}{6}=\frac{1056}{6}

Simplify:

x+19=176

x+19-19=176-19

x=157
