Add and subtract polynomials

Mathematics
1 answer:
Xelga [282]3 years ago
4 0
(w^2+5w) + (2w^2 +w +7)
 when adding or subtracting polynomials, just combine the like terms from each set:

w^2 + 2w^2 = 3w^2

5w +w = 6w

so you would have : 3w^2 + 6w + 7

Please help! I have no clue what im doing
prohojiy [21]

Answer:

y = -2x + 1

Step-by-step explanation:

So, first you can use rise over run between the two points to find the slope.

This will get you -6/3, which you can simplify to -2

Then, see where the y intercept is, which is at (0, 1)

The equation will be y = -2x + 1

What is 1/2(7x-6)=6x-10
erastova [34]

Answer:

Step-by-step explanation:

1/2(7x - 6) = 6x - 10

7/2x - 3 = 6x - 10 .....multiply by 2

7x - 6 = 12x - 20

-6 + 20 = 12x - 7x

14 = 5x

14/5 = x  <===

Line FG contains points F (3,7) and G (-4,-5) line HI contains points (-1,0) and I (4,6) lines FG and HI are. ?
ludmilkaskok [199]
FG : (3,7)(-4,-5)
slope = (-5 - 7) / (-4-3) = -12/-7 = 12/7

y = mx + b
slope(m) = 12/7
(3,7)...x = 3 and y = 7
now we sub, we r looking for b, the y int
7 = 12/7(3) + b
7 = 36/7 + b
7- 36/7 = b
49/7 - 36/7 = b
13/7 = b
so ur equation is : y = 12/7 + 13/7.....slope = 12/7, y int = 13/7

HI : (-1,0)(4,6)
slope = (6 - 0) / (4 - (-1) = 6/5

no need to go any farther.....these lines have different slopes...and their not negative reciprocals....so there will be one solution. Answer is : neither.

The first figure is dilated to form the second figure.
Alja [10]

1) The scale factor is 0.25 is true.

Step-by-step explanation:

Step 1:

The first figure is dilated to form the second figure. The shape is a rhombus.

It is given that the side length of the first figure is 5.8 and the side length of the second figure is 1.45.

Step 2:

To calculate the scale factor, we divide the measurement after scaling by the same measurement before scaling. In this case, it is the side length of the rhombus.

The scale factor = \frac{1.45}{5.8} = \frac{1}{4} = 0.25.

So the scale factor is 0.25. This is the first option.
