Answer:
(-1,7) is the midpoint of these two points
Step-by-step explanation:
Substitute the values of x from each table and see which values fit
For example in table d when x = 40 y = (-3/8)*40 + 75 = 60 which is the result given in table d
The other 2 values also fit table d
Answer is table d.
First, define the area of a triangle: A = 1/2bh. Let A = 16, and since it’s a right triangle, the base and the height can easily be translated to its two legs. Let one leg = x, and the other = x + 4. So this would give you the equation: 16 = .5(x)(x+4). Distribute so 16 = .5x^2 + 2x. You might want to get rid of the decimal/fraction, so multiply everything by 2 and this would give you 32 = x^2 + 4x. Recognizing that this will be a quadratic equation let x = 0 and bring everything unto one side, so 0 = x^2 + 4x - 32. Factor. 0 = (x+8)(x-4). Since a leg cannot be negative, x can only equal 4. This means that one leg is 4 and the other is 8.
This is D because if you add all the number up 117-2=115
1/3 ⇒ 4/12
1/4 ⇒ 3/12
3/12 + 4/12 = 7/12
You cannot put this as a mixed number
