4y^2 - (-3y - (19y^2 - 4y)) - (5 + (-9y - 5)) =
4y^2 - (-3y - 19y^2 + 4y) -( 5 - 9y - 5) =
4y^2 - (-19y^2 + y) - (-9y) =
4y^2 + 19y^2 - y + 9y =
23y^2 + 8y <==

In ΔUVW, the measure of ∠W=90°, UV = 6.2 feet, and WU = 1.2 feet. Find the measure of ∠V to the nearest tenth of a degree.
Crazy boy [7]

Answer:

m<V = 11.2 degrees

Step-by-step explanation:

In ΔUVW, the measure of ∠W=90°, UV = 6.2 feet, and WU = 1.2 feet.

From the triangle;

UV = hypotenuse = 6.2feet

WU = opposite = 1.2feet

Required

m<V

Using the SOH CAH TOA identity

sin m<V = opp/hyp

sin m<V = WU/UV

sin m<V = 1.2/6.2

sin m<V = 0.1936

m<V = arcsin(0.1936)

m<V = 11.16

m<V = 11.2 degrees ((to the nearest tenth of a degree)

A linear equation will have one unique solution when...
Katena32 [7]

Answer:

… you can write it in the form ax = b (a ≠ 0).

Step-by-step explanation:

In that case, there is one unique solution: x = b/a.

If a = 0 and b ≠ 0, we get 0x = b , and there are no solutions.

If a = 0 and b = 0, we get 0x = 0, and there are an infinite number of solutions.

Please help and thank you
Brut [27]

Answer:

A

Step-by-step explanation:

In these kind of functions: <em>adding outside of the absolute value moves the graph up</em>, <em>adding inside moves it to the left</em>.

So, since it is moved 4 to the right, there will be a <em>- 4 inside</em>.

Also, since it moves 6 up, there is a <em>+ 6 outside</em>.

The only equation to do so is A.
