Answer:
25
Step-by-step explanation:
In this equation, ax^2+bx+c, b = -1, a = 2, and c = -3. Solving, (-1)^2 - 4(2)(-3) = 1 - (-24), or 25.
Answer:
x=0
Step-by-step explanation:
The line is perpendicular to y axis and passes through origin. Thus it's x=0
Answer:
x = -1 and x = 1
Step-by-step explanation:
<em>Excluded values</em> are values that will make the denominator of a fraction equal to 0.
The fraction is (x+1)/(x² - 1)
x² - 1 = 0
x² = 1
x = ±1
The excluded values are x = -1 and x = 1.
I assume you're talking about a right triangle?
Then we use the Pythagorean Theorem: 73^2+48^2=c^2
This is equal to 5329+2304=c^2
7633=c^2
87.367=c
