Factor completely 49m4 + 140m2 + 100

Mathematics
1 answer:
postnew [5]3 years ago
5 0

Answer:

Step-by-step explanation:

Use identity : (a + b)²  =a² + 2ab + b²

49m⁴ + 140m² + 100 = 7²(m²)² + 2 * 7m² * 10 + 10²

                                  = (7m²)² + 2 *7m²*10 + 10²

                                   = (7m² + 10)²

                                   = (7m² + 10)(7m² + 10)

HELLP I WILL GIVE YOU A CROWN
ElenaW [278]

Answer:

A)The slope of the graph is 1

B) The table is 3

C) The equation is 1/2

D) The table

Step-by-step explanation:

y2-y1/x2-x1=the slope

Pick two undefined points {such as 5,0 and 0,-5)

5-0/0+5=1

The slope is 1.

~~~~~~~~~~

Same equation of slope, you just have to find two points (I chose 2,2 and 4,3

The slope of the equation y=0.5x+1 is 1/2 or 0.5

~~~~~~~~~~

You choose two points (I chose 2,9 and 1,6)

Slope equation

9-6/2-1=3/1=3

Slope is 3

~~~~~~~~~~~

The greatest change is in the table. You know this because it has the greatest slope and if you draw it out on a graph, it has the most significant change.

Good luck!

The trend line that Sylvie has drawn for her graph goes through the points (5, 0) and (4, 3). What is the equation of the line?
Andreas93 [3]

Answer:

y=-3x+15

Step-by-step explanation:

To find the equation of the line, you need to find the slope and y intercept. The slope is pretty easy, as the line goes down by 3 after going up by 1. This means that the slope is -3/1=-3. The y intercept is also pretty easy, as you know that the line will increase by 3 every time you go back 1 to the left. 3*4=12, meaning that going back 4 will take you up 12. 3+12=15, meaning that the equation of the line is y=-3x+15. Hope this helps!
