If the base of this triangle is 2 and the height is 1, what is the area?
| 105 | |
| 49 | |
| 1 | |
| 40\(\frac{1}{2}\) |
The area of a triangle is equal to ½ base x height:
a = ½bh
a = ½ x 2 x 1 = \( \frac{2}{2} \) = 1
Solve for z:
-8z + 5 < -4 - 6z
| z < 4\(\frac{1}{2}\) | |
| z < -\(\frac{1}{3}\) | |
| z < -1 | |
| z < 3 |
To solve this equation, repeatedly do the same thing to both sides of the equation until the variable is isolated on one side of the < sign and the answer on the other.
-8z + 5 < -4 - 6z
-8z < -4 - 6z - 5
-8z + 6z < -4 - 5
-2z < -9
z < \( \frac{-9}{-2} \)
z < 4\(\frac{1}{2}\)
