Answer:

The solution is (2, -2)

Step-by-step explanation:

In order to solve this, multiply the second equation by -5 and then add through.

5x - 4y = 18

-5x - 15y = 20

------------------

-19y = 38

y = -2

Now that we have the value of y, we can solve for x.

x + 3y = -4

x + 3(-2) = -4

x - 6 = -4

x = 2

Through point (0, 10) and PERPENDICULAR to the line through (-2, -9) and (-4, -17)?
inn [45]

Compute the slope of the line through (-2, -9) and (-4, -17):

\dfrac{-9-(-17)}{-2-(-4)}=\dfrac82=4

Any line perpendicular to this line will have slope -1/4. The one that passes through (0, 10) satisifes

y-10=-\dfrac14(x-0)\implies\boxed{y=10-\dfrac x4}

Suppose you know that <T and<S are supplementary, and that m<T=3(m<S). How can you find m<T?​
stealth61 [152]

Answer:

∠T = 135°

Step-by-step explanation:

Supplementary angles sum to 180°, thus

∠T + ∠S = 180

However, ∠T = 3∠S, hence

3∠S + ∠S = 180

4∠S = 180 ( divide both sides by 4 )

∠S = 45°, hence

∠T = 180° - 45° = 135°

Grade 10 math help please. Please show work
masha68 [24]

Answer:

43.94?

Step-by-step explanation:

I think if you use inverse cos you should get the correct number. So, to find cos, you need to know the adjacent side and the hypotenuse. Here, the reference angle would be the person holding the kite. The distance from the person to the barn is the adjacent side, which is 18. The string of the kite, I assume, would be 25.

cos(∅) = \frac{18}{25}

cos(∅) = 0.72

cos⁻¹(0.72) = 43.94

I don't know if that's what you're looking for, but... If it's not correct, lmk so I can rewrite it. :)
