Multiply.<br> (5x2-6x+2) x (4x2-3x)

stich3 [128]

Answer:

Step-by-step explanation:

(5 × 2 - 6x + 2) × (4 × 2 - 3x)

5 × 2 (4 × 2 - 3x) - 6x(4 × 2 - 3x) + 2(4 × 2 - 3x)

80 - 30x - 6x(4 × 2 - 3x) + 2(4 × 2 - 3x)

80 - 30x - 48x + 18x² - 6x

96 - 84x + 18x²

18x² - 84x + 96

Hope this helps! :)

What is the slope of the line (2,3) (1,-2)?

jarptica [38.1K]

Answer: The slope is 5

Step-by-step explanation:

You can calculate the slope of the line with this fomula:

$m=\frac{y_2-y_1}{x_2-x_1}$

Given the points (2,3) and (1,-2), you can identify that:

$y_2=-2\\y_1=3\\x_2=1\\x_1=2$

Now, the final step is to substitute these values into the formula $m=\frac{y_2-y_1}{x_2-x_1}$ , getting that the slope of this line is:

$m=\frac{-2-3}{1-2}$

$m=\frac{-5}{-1}\\\\m=5$
