Find the solution(s) to 2x2 + 5x – 3 = 0.
iren2701 [21]

Answer:

C and E

Step-by-step explanation:

Let's factor this the "old fashioned" way.  The standard form of a quadratic is

y=ax^2+bx+c

If you're familiar with the quadratic formula I'd say throw it into that, but if not, again, let's do it the "old fashioned" way.  

We need to find the product of our a and c.  Our a = 2 and our c = -3.  So that gives us a -6.  Now we have to find the factors of 6 (the negative right now doesn't matter so much).  The factors of 6 are 1, 6  and 2, 3.  Both of those possibilities will work to give us a +5, which is the linear term.  Puttng in the 2, 3 first:

0=2x^2+3x+2x-3

Now group the terms together into groups of 2:

0=(2x^2+3x)+(2x-3)

The idea is to factor out something common in each term so that what's left over in the parenthesis in both terms is exactly the same.  In the first term we can factor out a common x, and in the second term, the only thing common is a 1.  So that looks like this:

x(2x+3)+1(2x-3)

What's inside those parenthesis are not actually identical, so 2 and 3 won't work.  Lets try 1 and 6.  For those 2 numbers to equal a +5, the 6 is positive and the 1 is negative.  So let's try that:

(2x^2+6x)+(-x-3)

In the first term we can factor out the common 2x and in the second term we can factor out the common -1:

2x(x + 3) - 1(x + 3)

Now what's common is (x + 3), so we can factor THAT out and what is left over is 2x - 1:

(x + 3)(2x - 1) = 0

If x + 3 = 0, then x = -3

and if 2x - 1 = 0, then 2x = 1 and x = 1/2

Raven has been babysitting to earn enough money to buy a concert ticket that costs $24. She already had $12 and she earned $20 b
AlladinOne [14]

Answer:

The  money Raven has left after she buys the concert ticket is $8 .

Step-by-step explanation:

As given

Raven has been babysitting to earn enough money to buy a concert ticket that costs $24.

She already had $12 and she earned $20 babysitting.

Total money Raven have = $12 + $20

                                         = $ 32

Money Raven has left after she buys the concert ticket = Total money Raven have - Cost of the concert ticket .

Money Raven has left after she buys the concert ticket = 32 - 24

Money Raven has left after she buys the concert ticket = $8

Therefore the  money Raven has left after she buys the concert ticket is $8 .

saveliy_v [14]

Answer: A, E, B, and C

Step-by-step explanation:

A regression procedure require all of the following

1. Linearity: The relationship between X and the mean of Y must always be linear. C fulfills this condition

2. Homoscedasticity: Sometimes known as the homogeneity of avariance is always same for any given value of X. A also fulfills this condition.

3. Normality: A fixed values of X, and Y is always normally distributed. B and E fulfills this condition.
