Answer:

D, or the last option.

Step-by-step explanation:

See how the rotation does not say whether it is Clockwise or Counterclockwise?

Now, what that means, is that it will, default, be CCW. I don't know why, but math teachers are like that.

Now, 80* and 10* add up to 90* (because they are both unmarked and going to the same direction).

So, 90* rotation CCW. Simple! Thus, the last option should be correct.

Hope this helps!

P.S. Stay Safe!

Factor: 10x^3-35x^2-12x+42 I'll give brainliest :) but please show all work.

alexandr402 [8]

Answer:

$\left(2x-7\right)\left(5x^2-6\right)$

Explanation:

$\hookrightarrow\sf 10x^3-35x^2-12x+42$

using associative property, separate

$\hookrightarrow\sf \left(10x^3-35x^2\right)+\left(-12x+42\right)$

take common term, factorise

$\hookrightarrow\sf 5x^2\left(2x-7\right)-6\left(2x-7\right)$

final answer

$\hookrightarrow\sf \left(2x-7\right)\left(5x^2-6\right)$

Consider the system of equations.

Xelga [282]

Answer:

D and C

Step-by-step explanation:

Given the 2 equations

3x - y = 5 → (1)

2x + 3y = - 15 → (2)

Multiplying (1) by 3 and adding to (2) will eliminate the y- term

9x - 3y = 15 → (3)

Add (2) and (3) term by term to eliminate y

11x + 0 = 0

11x = 0 ⇒ x = 0

Substitute x = 0 into either of the 2 equations and solve for y

Substituting into (2)

2(0) + 3y = - 15

0 + 3y = - 15

3y = - 15 ( divide both sides by 3 )

y = - 5

solution is (0, - 5 )

If varies inversely as . It is known that = 10 when = 3, find the value of when = 5.

Leto [7]

Answer:

y = 6

Step-by-step explanation:

If x varies inversely proportional as y.

$x=\dfrac{k}{y}$ , k is constant of proportionality

k = xy

When x = 3 and y = 10

k = 3×10

k = 30

Put x = 5,

$y=\dfrac{k}{x}\\\\y=\dfrac{30}{5}\\\\y=6$

So, the value of y is 6 when x is 5.
