Answer:
zero
Step-by-step explanation:
The answer to that question is best found by looking at the value of the <em>discriminant</em>.
For quadratic ax^2 +bx +c = 0, the value of the discriminant is ...
d = b^2 -4ac
Here, you have a=3, b=8, c=7, so the discriminant is ...
d = 8^2 -4(3)(7) = 64 -84 = -20
When the discriminant is negative, both solutions are complex (not real).
There are zero real solutions to this equation.
Answer:
x=2 and y=1
Step-by-step explanation:
hope this helps!
The answer is C. If you use the pythagorean theorem,

, and connect the two points together at a right angle and pug in the lengths of the two lines to the equation then the answer should be C.
Answer:
x = 24
Step-by-step explanation:
=
+ 4 Multiply though by 12 to clear the fraction
4(6 + x) = 3x + 48 Distribute the 4)
24 + 4x = 3x + 48 Subtract 3x from both sides of the equation
24 + x = 48 Subtract 24 from both sides.
x = 24
