(-2/5)-(-1/8)
Need to make the denominators the same
(-16/40)-(-5/40)
Multiply -2/5 by 8
Multiply -1/8 by 8
-- sign= positive
-16/40+5/40
Answer=-11/40
Answer:
A = 25 in^2
Step-by-step explanation:
The area of a triangle is given by
A = 1/2 bh
A = 1/2 (10)(5)
A =1/2 *50
A = 25 in^2
Answer:
The angle would be acute
Step-by-step explanation:
Answer:
x = 3 and y = 7
Step-by-step explanation:
2x + y = 13
<u>+ x - y = -4</u> (adding both equations)
3x - 0y = 9
3x = 9
x = 9/3
x = 3
now substituting
x - y = -4
3 - y = -4
- y = -4 - 3
- y = -7
y = 7 (the negative sign on both sides get canceled)
Therefore,
x = 3 and y = 7
Happy to help :)
I would say the second, y = 3x + 4, that intersects the y axis at 4 and the slope is surely 3.
