Find the real solutions of the equation by graphing

Vlada [557]

Answer:

C. 0, 1.29, -0.65

Step-by-step explanation:

The real solutions of the equation $19x^3-12x^2-16x=0$ is where the graph of $y=19x^3-12x^2-16x$ intersects the x-axis.

This means that we need to graph $y=19x^3-12x^2-16x$ using a graphing software.

From the graph shown in the attachment $x=0$ , $x=1.29$ , and $x=-0.65$ are the real solutions.

The correct choice is C

For the function f(x) = –5x, which ordered pair will be a point on the graph of the function?

Drupady [299]

It's D: (0,0)
This is because when you put 0 in for x your y value will equal 0 and that is one of your answers, so it's the point (0,0)

What is the slope of a line parallel to the line with equation 5x + 3y = 7?

weeeeeb [17]

Answer:

-5/3

Step-by-step explanation:

Parallel lines are lines which have the exact same slope but different y-intercepts. We can find the slope by converting to slope-intercept form, y=mx+b from standard form.

We convert by using inverse operations to isolate y.

5x+3y=7

5x-5x+3y=7-5x

0x+3y=-5x+7

3y=-5x+7

$\frac{3y}{3} =\frac{-5x+7}{3} \\y=\frac{-5}{3}x+\frac{7}{3}$ .

The slope is -5/3. SInce parallel lines have the same slope, the slope for a parallel line will be -5/3.
