Answer: the above stated equation is a quadratic equation
Step-by-step explanation:
Given the following equations
y = x^2 + 5x - 3....equation 1
y-x = 2
y = x + 2........equation 2
Let equation 1 equal equation 2
x^2 + 5x -3 = x + 2
Bringing the equation to one side and equating to zero
X^2 +5x - 3 -x -2 = 0
X2 + 5x -x -3 -2 = 0
X^2 + 4x -5
Solving the aquatic equation
(x + 5)(x -1) = 0
X + 5 = 0
X1 = -5
X- 1 = 0
X2 = 1
To prove:
Substitute the values for x1and x2 into the equation x^2 + 4x - 5 = 0
Answer:
Sam made it -24 versus 24 (29-5=24 not -24)
(Sam failed to flip the inequality)
Step-by-step explanation:
-4x + 5 > 29
Subtract 5 from each side
-4x+5-5 > 29-5
-4x > 24 Sam made it -24 versus 24 (29-5=24 not -24)
Divide by -4 Remember to flip the inequality
-4x/-4 < 24/-4 (Sam failed to flip the inequality)
x < -6
If 2 1/2 posterboard is enough for 1/2 of the project, it will take another 2 1/2 posterboard to display the other half of the project.
2 1/2 + 2 1/2 = 4 + 1/2 + 1/2 = 4 + 1 = 5
Answer: 5 posterboard.
That's the beginning of Euler's number ' e '.
