Simplify (2x + 3)(x – 4) = ?

1 answer:

5 0

Use the FOIL method (first, outside, inside, last) to multiply:

2x^2-8x+3x-12

This can be simplified even more into:

2x^2-5x-12.

Hope this helped!

Answer:

Step-by-step explanation:

You haven't attached any graphs but as there area 3 distinct roots the graph will have 2 loops.

Also the end behaviour will be rising from the left negative values of f(x) and at the right it will rise to positive f(x).

Answer:

Part A: Option A

Part B: Option C

Step-by-step explanation:

Given two points (7, 5) and (21, 15)

we have to find the slope of the line passing through above two points.

The slope of line can be calculated as

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

$m=\frac{15-5}{21-7}=\frac{10}{14}=\frac{5}{7}$

Option A is correct.

Part B: Also given another line with a slope that is one-third that of the slope of above and passes through the origin and the point

we have to find the point.

$slope=\frac{1}{3}\times \frac{5}{7}=\frac{5}{21}$

The equation of line becomes

$y-y'=m(x-x')$

$y-0=\frac{5}{21}(x-0)$

$21y=5x$

The point which satisfies the above equation passes through the line.

$(3,5):21(5)=5(3)$ Not satisfied

$(3,7):21(7)=5(3)$ Not satisfied

$(21,5):21(5)=5(21)$ Satisfied

$(21,7):21(7)=2(21)$ Not satisfied

Hence, the line passes through the point (21, 5)

Option C is correct.
