Answer: A) (4, 6)

Step-by-step explanation:

1. You can plot the given points (-2,-2) and (4,-2), as you can see in the first graph attached.

2. The formula for calculate the area of a triangle is:

A=\frac{bh}{2}

Where<em> b</em> is the base and <em>h</em> is the height.

3. As you can see in the first graph, the lenght of the base is:

b=6units

So, you must solve for the heigth:

h=\frac{2A}{b}=\frac{2(24units^{2})}{6units}=8units

3. Add 8 to the y-coordinate of both points given in the problem to know the coordinates of the other vertex:

(-2,-2+8)=(-2,6) (This is not an option)

(4,-2+8)=(4,6) (Option A. This is the answer).

4. Then, the triangle is shown in the second graph.

Faris's gas tank is 1/10 full. After he buys 24 liters of gas, it is 2/5 full. How many liters can Faris's tank hold?
Arisa [49]

Answer:

80 liters

Step-by-step explanation:

24 liters is the difference between 2/5 full and 1/5 full.

Let x = number of liters in full tank.

2/5 x - 1/10 x = 24

4/10 x - 1/10 x = 24

3/10 x = 24

1/10 x = 8

x = 80

Answer: 80 liters
