Which is the right answer?

Mathematics
1 answer:
Amanda [17]3 years ago
6 0

Answer:

D

Step-by-step explanation:

Since the triangle is right use the sine trig ratio to solve for x

noting that sin45° = \frac{1}{\sqrt{2} } ← exact value

sin45° = \frac{opposite}{hypotenuse} = \frac{8}{x}

Multiply both sides by x

x × sin45° = 8 ( divide both sides by sin45° )

x = \frac{8}{sin45} = \frac{8}{\frac{1}{\sqrt{2} } } = 8\sqrt{2}

Which ordered pair (a, b) is the solution to the following system of equations?
Kamila [148]

Answer:

  (-13, -4)

Step-by-step explanation:

It is about as easy to try the solutions as it is to find them from scratch.

__

However, we can determine which one it is by adding twice the second equation to the first.

  (-2a +3b) +2(a -4b) = (14) +2(3)

  -5b = 20

  b = -4 . . . . . . matches the first choice

How do you solve this
fiasKO [112]
(((x + y) / 3) + (1 / x)) / (5 + (15 / x))
The best way is to make it one fraction.
Multiply by ((3x/3x) / (3x/3x)) to remove the other fractions.
((x(x + y)) + 3(1)) / (5(3x) + 3(15))
(x^2 + xy + 3) / (15x + 45)
Then factor to simplify
(x^2 + xy + 3) / (3(x + 15))
