That triangle has a horizontal base with y=2. The length of that base is RS=1-(-4)=1+4=5. The height of the triangle is the vertical distance from line y=2 to T(-5,-4). That height is 2-(-4)=2+4=6. The area of the triangle is base * height/2 = 5*6/2= 15
The answer is 15 units ^2

Step-by-step explanation:
Simple math
Answer:
A)
Step-by-step explanation:
To find the answer we must solve each of the systems separately. Starting with the first one:
x + y = 2
2x - y = 10
We must find what x or y is equal to and then replace it in the second equation. I'll go with y as it seems easier:
x + y = 2
y = 2 - x
Now that we found y we replace it in the second equation this way. Be careful with the signs, the minus with change our signs:
2x - (2 - x) = 10
2x - 2 + x = 10
3x = 12
x = 12/3
x = 4
Now that we have x, we replace the variable with its value in one of the equations. Again, for simplicity I'll go with the one that seems easier.
4 + y = 2
y = 2 - 4
y = - 2
Answer:
x = 6/5
Step-by-step explanation:
3x - 3/5 + 2 = 5
<u>Add 3/5 and -2 on both sides.</u>
3x = 5 + 3/5 - 2
3x = 18/5
<u>Divide 3 on both sides.</u>
x = 18/5 ÷ 3
x = 18/15
x = 6/5
