In goes 4.

We then subtract 7.

So, 4 - 7 = -3

We now divide -3 by 3.

The output is -1.

-1 would be your answer. 4-7=-3, which you'd divide by 3 to get -1. Hope this helps.

Write the equation 2y-4x=5 In the form y=my+b

Vika [28.1K]

Answer:

y = 2x + 2.5

Step-by-step explanation:

To begin, we start with the equation 2y - 4x = 5.

We will add 4x to both sides to move the x term to the right side of the equation, giving us:

2y - 4x + 4x = 4x + 5

2y = 4x + 5

Next, we should divide by 2 to cancel out the coefficient on the y-term and isolate it on the left side of the equation:

2y/2 = 4x/2 + 5/2

y = 2x + 5/2

Therefore, your answer is y = 2x + 5/2 or y = 2x + 2.5.

Hope this helps!

Please Help, Will give Brainliest!<br> Law Of Cosines.

stealth61 [152]

Answer:

B) a = 6.7, B = 36°, C = 49°

Step-by-step explanation:

Fill in the numbers in the Law of Cosines formula to find the value of "a".

a² = b² + c² -2bc·cos(A)

a² = 4² +5² -2(4)(5)cos(95°) ≈ 44.4862

a ≈ √44.4862 ≈ 6.66980

Now, the law of sines is used to find one of the remaining angles. The larger angle will be found from ...

sin(C)/c = sin(A)/a

sin(C) = (c/a)sin(A)

C = arcsin(5/6.6698×sin(95°)) ≈ 48.31°

The third angle is ...

B = 180° -A -C = 180° -95° -48.31° = 36.69°

The closest match to a = 6.7, B = 37°, C = 48° is answer choice B.
