Answer:

  a) y = -18x +200

  b) 38 gallons

Step-by-step explanation:

<h3>a)</h3>

The slope formula can be used to find the slope:

  m = (y2 -y1)/(x2 -x1)

  m = (110 -137)/(5 -3.5) = -27/1.5 = -18

The y-intercept can be found from ...

  b = y -mx = 110 -(-18)(5) = 200

The slope-intercept equation describing the relation is ...

  y = -18x +200

__

<h3>b)</h3>

After 9 hours, the amount of gas remaining is ...

  y = -18(9) +200 = -162 +200 = 38 . . . gallons remaining

The endpoints of a diameter of a circle are A(3,1) and B(9,9). Find the area of the circle in terms of pie
andrey2020 [161]

Answer:

The answer is 25\pi units squared.

Step-by-step explanation:

If we find the diameter, we can find the radius by halving the diameter.

We can find the diameter by using the endpoints of the diameter.

The distance formula will give us the length between (3,1) and (9,9).

The distance formula is \sqrt{(x_2-x_1)^2+(y_2-y_1)^2}.

The distance between the x's is 9-3=6.

The distance between the y's is 9-1=8.

The distance between the points is given by \sqrt{6^2+8^2}=\sqrt{36+64}=\sqrt{100}=10.

The radius is therefore \frac{10}{2}=5.

We are asked to find the area of this circle.

The formula for finding the area of a circle is \pi r^2.

Since the radius is 5, then the area in terms of \pi,(pi), is \pi (5)^2=\pi (25).

The answer is 25\pi units squared.

Solve the inequality y − 6&gt;10
fredd [130]

if y-6 > 10, and 16-6 = 10, then y > 16 since 17-6 = 11, which is greater than 10. Any number greater than 16 can fulfil this inequality.

Stacy and Travis are rock climbing. Stacy's rope is 4 feet shorter than 3 times the length of Travis' rope. Stacy's rope is 23 f
Gnesinka [82]
Lets say travi's rope is T feet long
and Stacy's rope is 23 feet long
3T-4=23
3T=23+4
3T=27
T=9 feet long
so Travis rope is 9 feet long
