Yes, 50^x = 17 is an exponential equation with base 50, and the task here is to solve it for x.
1) Take the log of both sides: x log 50 = log 17
2) Divide both sides b log 50:
log 17
x = ----------
log 50
3) This last result can't be simplified, but can be evaluated"
x = 1.2304 / 1.6990 = 0.724 (approx.)
If the lines are parallel, the have to have the same slope
so if the red line has a slope of 2/5, the green line will have a slope of 2/5
Answer: 2/5
Choice B
Answer:
Option D. two complex roots
Step-by-step explanation:
we know that
In a quadratic equation of the form 
the discriminant D is equal to
in this problem we have
so
substitute the values
The discriminant is negative
therefore
The quadratic equation has two complex roots
Answer:
D
Step-by-step explanation:
2x + 5y = - 10 Subtract 2x from both sides
5y = -2x - 10 Divide by 5
y = -2x/5 - 10/5
y = 0.4x - 2
The slope is minus so the line is going from lower right to upper left as B and D are doing.
The y intercept is - 2. B goes through + 2 so it is not the answer.
The answer is D
