Answer:

Mile marker 114

Step-by-step explanation:

Our slope is 60 mph

Let x be the time in hours  and y be the miles

Our point is (1 ,84)

We have a point and a slope

We can use point slope form to find the equation

y-y1 = m(x-x1)

y-84 = 60(x-1)

We want to find y when the time is 90 minutes

We need to change 90 to hours

90 minutes * 1 hour/60 minutes = 1.5 hours

Substitute this into the equation to find the miles, which is the mile marker

y - 84 = 60 (1.5 -1)

y - 84 = 60(.5)

y -84 = 30

Add 84 to  each side

y-84+84 = 30+84

y = 114

You should pass mile marker 114

OLEGan [10]

Answer:

x² + 2x + y² + 4y = 20

(x² + 2x + 1) - 1 + (y² + 4y + 4) - 4 = 20

(x + 2)² + (y + 4)² - 5 = 20

(x + 2)² + (y + 4)² = 25

Therefore, the center is (-2, -4) and the radius is √25 = 5.

Answer:

The length of side AC is 5 units.

The areas of triangle ABC is 10 square units.

Step-by-step explanation:

From point A (1,3) to point C (1,-2) is 5 units

To check this:

3 - (-2) = 3 + 2 =5

We're subtracting since the point went down (from positive 3 to negative 2)

Now for the area:

Area formula for a triangle: \frac{1}{2}bh = \frac{1}{2}⋅b⋅h

We already found the height (length) : 5

The base is from point C (1,-2) to point B (5,-2), which is 4 units

To check this:

5 - 1 = 4

Now that we have found the base and height, Let's solve:

\frac{1}{2}⋅4⋅5 = \frac{1}{2}⋅20 = 10

Our area is 10 square units.

Hope that helps :)
