25x^2+1=5 quadratic

1 answer:

3 0

25x² + 1 = 5

25x² + 1 - 5 = 0

25x² - 4 = 0 By difference of two squares

(5x)² - (2)² = 0

(5x - 2)(5x + 2) = 0

5x - 2 = 0 or 5x + 2 = 0

5x = 0 + 2 5x = 0 - 2

5x = 2 5x = -2

x = 2/5 x = -2/5

x = 0.4 x = -0.4

x = + 0.4 or -0.4

Find Distance (4,6) (-4,-3)

vampirchik [111]

Answer:

$\sqrt{145}$

Step-by-step explanation:

The distance formula states that the distance between two points $(a,b)$ and $(c,d)$ is $\sqrt{(a-c)^2+(b-d)^2}$ .

The two points we have are $(4,6)$ and $(-4,-3)$ . Plugging these numbers into the distance formula, we have

$\sqrt{(4-(-4))^2+(6-(-3))^2$ .

Simplifying with order of operations, first using the distributive property, gives

$\sqrt{(4+4)^2+(6+3)^2$ .

Squaring and adding gives

$\sqrt{(4+4)^2+(6+3)^2}=\sqrt{8^2+9^2}\\~~~~~~~~~~~~~~~~~~~~~~~~~~~~=\sqrt{64+81}\\~~~~~~~~~~~~~~~~~~~~~~~~~~~~=\boxed{\sqrt{145}},$

which is the answer in simplest form. This also rounds to about 12.04.

-4x + 2y = -8 in slope interception form (y= mx + b )

Nostrana [21]

Answer:

y=2x-4

Step-by-step explanation:

so we just have to rearrange this to

2y=4x-8

we can do this by adding 4x to both sides

then we divide by 2

y=2x-4
