Answer:
D = 0
Step-by-step explanation:
Given
x-intercept = -3
Required
What does the discriminant represent?
The discriminant of a quadratic function can take any 3 values; these are as follows;
- When D > 0
- When D < 0
- When D = 0
Which translates to
- signifies that two different real roots exist
- signifies that only complex roots exist
- signifies that the two identical real roots exist
The question says that x-intercept = -3 is the only value;
This means that: x = -3 or x = -3
Analyzing the roots
- 3 and -3 are identical
- -3 and -3 are real
This means they satisfy condition number 3;
Hence, D = 0
2:4 is the probability. It is more likely to receive a ordinary quarter, but the probability of the two headed quarter is still great enough to get it.
Answer:
- 3y² - 7y + 6
Step-by-step explanation:
Given
(- 3y + 2)(y + 3)
Each term in the second factor is multiplied by each term in the first factor, that is
- 3y (y + 3) + 2(y + 3) ← distribute both parenthesis
= - 3y² - 9y + 2y + 6 ← collect like terms
= - 3y² - 7y + 6
Answer:
2
Step-by-step explanation:
how many numbers are to the right of the decimal point? that would be 2 :)
Answer:
x= -9
Step-by-step explanation:
Sin is equal to cos. x-3=2x+6 and you solve.
