The value of x is: Solve for x by simplifying both sides of the equation, then isolating the variable.
x=−9/4
Greatest Common Is The More Times It Can Go In To That Number. And The Least Is The Least Many Times.
Answer:
v = 7
is the value for which
x = (-21 - √301)/10
is a solution to the quadratic equation
5x² + 21x + v = 0
Step-by-step explanation:
Given that
x = (-21 - √301)/10 .....................(1)
is a root of the quadratic equation
5x² + 21x + v = 0 ........................(2)
We want to find the value of v foe which the equation is true.
Consider the quadratic formula
x = [-b ± √(b² - 4av)]/2a ..................(3)
Comparing (3) with (2), notice that
b = 21
2a = 10
=> a = 10/2 = 5
and
b² - 4av = 301
=> 21² - 4(5)v = 301
-20v = 301 - 441
-20v = -140
v = -140/(-20)
v = 7
That is a = 5, b = 21, and v = 7
The equation is then
5x² + 21x + 7 = 0
Answer:
<em>C. 1/60</em>
Step-by-step explanation:
Probability of 3 on a cube: 1 / 6
Probability of 9 from cards 1-10: 1/10
1/6 x 1/10 = 1/60
False. Two supplementary add up to 180 degrees.
