The descriminant is b^2-4ac so for 26 it would be -5^2 - 4 (1) (7). The quadratic formula is -B plus or minus the square root of b squared minus 4ac over 2a
Answer:
No
Step-by-step explanation:
Choosing blue or red: 3 blue + 4 red = 7 marbles
3 blue + 2 green + 4 red + 1 yellow = 10 marbles
Probability blue or red marble: 7/10
Choosing a marble that isn't blue or red: 2 green + 1 yellow = 3 marbles
Total marbles: 3 blue + 2 green + 4 red + 1 yellow = 10 marbles
Probability non-blue or red marble: 3/10
Answer:
B. y = x + 3
Step-by-step explanation:
Let m represent the slope of the line.
Let c represent the y-intercept of the line.
Then the equation of the line with slope m and y-intercept c is given by ![\[y=mx+c\] ](https://tex.z-dn.net/?f=%5C%5By%3Dmx%2Bc%5C%5D%0A)
In this case, the value of m is 1 and the value of c is 3.
Substituting the given values in the equation:
![\[y=x+3\] ](https://tex.z-dn.net/?f=%5C%5By%3Dx%2B3%5C%5D%0A)
Among the given options, option B represents the correct equation of the line.
