What is the solution set of 2x2-3x=5

Mathematics
1 answer:
Kryger [21]3 years ago
7 0

You use the quadratic formula:

2x {}^{2} - 3x = 5

2x {}^{2} - 3x - 5 = 0

x = \frac{3 + - \sqrt{9 -4(2)( - 5)}}{2 \times 2}  

x = \frac{3 + - \sqrt{49} }{4}  

x = \frac{3 + 7}{4} \: and \: x = \frac{3 - 7}{4}  

x = \frac{5}{2} \: and \: x = - 1

Does the order in which the two transformations in a composite transformation affect the final
kap26 [50]

The order in which the two transformations in a composite transformation affect the final answer

<h3>How to determine the composite transformation?</h3>

To determine if order matters or not, I will use the following example and illustration.

Let the coordinate of point A be:

A = (2, 5)

Perform the following transformations:

  • Translate by (x, y + 1)
  • Dilate by a scale factor of 2

First order: Translation before dilation

The translation by (x, y + 1) would give:

A' = (2, 5 + 1)

A' = (2,6)

The dilation by a scale factor of 2 would give

A" = 2 * (2,6)

A" = (4,12)

Second order: Dilation before translation

The dilation by a scale factor of 2 would give

A' = 2 * (2,5)

A' = (4,10)

The translation by (x, y + 1) would give:

A'' = (4, 10 + 1)

A'' = (4,11)

See that the final coordinates in both orders are not the same.

Hence, the order in which the two transformations in a composite transformation affect the final answer

Which rule describes the relationship between the x- and y- coordinates on line m?
const2013 [10]

Answer:

y = 2x - 1

Step-by-step explanation:

None of those would be correct, the line on the graph is y = 2x - 1 because the slope of the line is 2 and the y -intercept -1.

You can also check, we know that on the graph the coordinates where the dots are located are: (2,3),(3,5),(4,7) where the first number is x and second is y coordinate.

Check answer:

Let x=2 if this is correct y should be equal to 3 because of the first point (2,3).

y = 2(2)-1 = 4 - 1 = 3

check the other points if you want to confirm.

In my opinion I would use the mean. But the options that are given I would choose answer A. But I'm not 100% sure.
