Answer:

x = -0.8\ or\ x = 0.5

Step-by-step explanation:

Given [Missing from the question]

6x^2 + 2x - 2.5 = 0

Required

Solve

Using factorization, we have:

6x^2 + 2x - 2.5 = 0

Expand 2x

6x^2 - 3x+5x  - 2.5 = 0

Factorize

3x(2x - 1)+2.5(2x  - 1) = 0

Factor out 2x - 1

(3x +2.5)(2x  - 1) = 0

Split:

(3x +2.5) = 0\ or\ (2x  - 1) = 0

In both cases, solve for x

3x = -2.5\ or\ 2x = 1

x = -\frac{2.5}{3}\ or\ x = \frac{1}{2}

x = -0.8\ or\ x = 0.5 --- approximated

Does this look correct?
Neko [114]
That is not correct.  I will help you.  Begin by subtracting the 9x from both sides, like this:  9x - 9x + 2y = 6 - 9x.  That simplifies to 2y = -9x + 6.  Now divide both sides by 2 to get y all alone, like this:  \frac{2y}{2}=- \frac{9}{2}x+ \frac{6}{2}.  That reduces down to y=- \frac{9}{2}x+3.  That is slope-intercept form.  y = mx + b.

A 13?-foot board is cut into two pieces. The longer piece is 7.5 feet longer than the shorter piece. What is the length of each?
chubhunter [2.5K]

Answer:

The smaller board would be 2.75 feet and the longer one would be 10.25 feet.

Step-by-step explanation:

In order to find this, assume the shorter board is equal to x. Next, we would know that the longer board would be equal to x + 7.5. Using these two assumptions, we can add the lengths together, set equal to 13 and then solve for x.

x + (x + 7.5) = 13

2x + 7.5 = 13

2x = 5.5

x = 2.75

Now that we have the length of the shorter board, we can add 7.5 to it to get the larger one.

2.75 + 7.5 = 10.25
