Answer:

- 6x² - 2x + 1

Step-by-step explanation:

Given

(2x³ - 4x² - 3x + 5) + (- 2x³ - 2x² + x - 4)

Both parenthesis are distributed by 1 thus just remove them

= 2x³ - 4x² - 3x + 5 - 2x³ - 2x² + x - 4 ← collect like terms

= - 6x² - 2x + 1

A, B, and C are midpoints of ∆XYZ. What is the length of yz

beks73 [17]

Answer:

Step-by-step explanation:

Comment

When you join 2 consecutive midpoints with a line between them, the length of that line is 1/2 the length of the side opposite the line you just drew.

In other words 24 is 1/2 the length of yz.

Solution

1/2 yz = AB

AB = 24

1/2 yz = 24 Multiply both sides by 2

2(1/2 yz) = 2*24

yz = 48

Answer

yz = 48

Calculate the slope of the line on the graph

Tamiku [17]

Answer:

3.5 (meters per second)

Step-by-step explanation:

To calculate the slope, we need two points. Let's see if we can select two points from the graph.

From the graph, we can pick out two possible points.

At the beginning, (0,2.5) is a valid candidate.

And at the end, with (5,20). Thus, let's use the slope formula to calculate the slope.

The slope formula is:

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

Let (0,2.5) be x₁ and y₁ and let (5,20) be x₂ and y₂. Thus:

$m=\frac{20-2.5}{5-0}$

Simplify:

$m=\frac{17.5}{5}\\ m=3.5$

Thus, the slope is 3.5 meters per second.

Further notes:

And the entire equation will be:

$m=3.5s+2.5$
