Evaluate 5x²-3(x-2)+x for x=3

Zepler [3.9K]

Answer:

45

Step-by-step explanation:

Evaluate 5 x^2 - 3 (x - 2) + x where x = 3:

5 x^2 - 3 (x - 2) + x = 5×3^2 - 3 (3 - 2) + 3

3^2 = 9:

5×9 - 3 (3 - 2) + 3

3 - 2 = 1:

5×9 - 3 + 3

5×9 = 45:

45 - 3 + 3

45 + 3 = 48:

48 - 3

Use the following work shown below to answer the following question.

zysi [14]

Answer:

$\frac{3 + \sqrt{3x} }{3 - x}$

Step-by-step explanation:

You can use the work they gave you and continue from there:

$\frac{\sqrt{3}(\sqrt{3}) + \sqrt{3}(\sqrt{x}) }{(\sqrt{3}) ^{2} - (\sqrt{x} )^{2} }$

First, simplify the numerator:

$\frac{3 + \sqrt{3x} }{(\sqrt{3}) ^{2} - (\sqrt{x}) ^{2} }$

Finally, simplify the denominator:

$\frac{3 + \sqrt{3x} }{3 - x}$

The graph shows the proportions of blue paint and yellow paint that Briana mixes to make green paint. What is the slope of the l

kotegsom [21]

Answer:

Slope = ⅚

Step-by-step explanation:

Using the coordinates of two points in the graph, say (0, 0) and (6, 5).

$\frac{y_2 - y_1}{x_2 - x_1} = \frac{5 - 0}{6 - 0} = \frac{5}{6}$

The slope of the graph is ⅚.

The slope represents the ratio of proportion of yellow paint to blue paint that must be mixed together to produce green paint.

This means, to make green paint, for every 5 parts of yellow paint, 6 parts of blue paint is required to be added as a mixture.
