Always true because when you solve it out you end up with 7x-8<7x+13 and then you subtract the 7x from both sides and you get -8<13 and -8 is less than 13.
Do not know # 1 working on it.
2)There are 120 permutations. (5*4*3*2)
Please rate brainliest answer please.
Q - 12 = 89
Q = 89 + 12
Q = 101
The function is y = 1/2 x² - 2 x and the base of the triangle cannot be 3 cm.
let the base of the triangle be x
Height of the triangle = x - 4
Area of triangle = 1/2 × base × height
Area = 1/2 × x × (x-4)
Area = 1/2 (x² - 4x)
Area = 1/2 x² - 2 x
We can also write it as a function:
y = 1/2 x² - 2 x
Domain = (3 , ∞)
Range = [0, ∞)
Since 3 is not included in the domain, base of the triangle cannot be 3 cm.
Therefore, the function is y = 1/2 x² - 2 x and the base of the triangle cannot be 3 cm.
