Answer: The equation in slope intercept form is
y = 2x/5 + 4/5
Step-by-step explanation:
The equation of a straight line can be represented in the slope-intercept form, y = mx + c
Where c = y intercept
m represents the slope of the line.
The given equation is expressed as
2x - 5y + 4 = 0
Adding 5y to the left hand side and the right hand side of the equation, it becomes,
2x - 5y + 5y + 4 = 5y
5y = 2x + 4
Dividing the left hand side and the right hand side of the equation by 5, it becomes,
5y/5 = 2x/5 + 4/5
y = 2x/5 + 4/5
Answer:
C) The discriminant is 0.
Step-by-step explanation:
Since the graph of the quadratic equation has only one x-intercept, we can conclude that the quadratic has only one real root.
If a quadratic equation has only one real root, then the discriminant is 0
If 1 mile = 1.609 km then we can use it as the conversion factor in the following way, remembering that the equation has to be set so that the miles cancel with miles.
4.5 miles =
⇒ 7.2405 km
(0,4) the y intercept is 4
The slope is traveling upwards
Given that:
Answer: B and C
20/15=1 1/3
Explanation:
20/15= (2 2*5) / (3*5)
=2 2/3= 4/3
4/3= (1*3+1) / 3= 1+ 1/3= 1 1/3
Final answer written three ways:
Positive improper fraction:
20/15= 4/3
Mixed number:
20/15 1 1/3
Decimal number:
20/15= 1.333333
