Answer:
Excluded Value : 3 and -5
Step-by-step explanation:
hello :
Excluded Value : and
the excluded value when : x²+2x-15=0
(
x²+2x+1)-1-15=0
means : (x+1)²-16=0 (x+1)²-4² = 0
by identity : a²-b² =(a-b)(a+b)
(x+1-4)(x+1+4) =0 so : (x-3)(x+5) =0 means : x-3=0 or x+5=0
x=3 or x= -5
Excluded Value : 3 and -5
Answer:
(0,9) and (18,0)
Step-by-step explanation:
To find the x-intercept, set y = 0. Note how this equation x + 2y = 18 becomes x = 18. Thus, the x-intercept is (18,0).
To find the y-intercept, set x = 0. Then 2y = 18, and y = 9. The y-intercept is (0,9).
The value of x from the given expression is; x= -2/3

Answer:
B. False
Step-by-step explanation:
According to pythagorean theorem, for this to be a right triangle, the sum of square of the length of the two legs must equal square of the length of the hypotenuse (longest side).
So 
should equal 
- <em>We also know that
</em>
Hence, 
, and
They ARE NOT EQUAL, so the triangle is NOT a right triangle.
