Hello,
Let's assume n the number searched.
nine less 3 times n is written 9-3n
The standard form would be y = 7x^2 - 42x + 67
Answer:
No
Step-by-step explanation:
If we use the Pythagorean theorem, we can find if it is a right triangle. To do that, set up an equation.
If the triangle is a right triangle, c would equal 11
Solve.
Then find the square root of 100.
The square root of 100 is 10, not 11.
So this is not a right triangle.
I hope this helps!
Y = |x| - 4 due to the fact it touches (0,4)
