A function is a relationship that each input (element of the domain) is paired with exactly one output (element in the range).

In function notation, f(x), the “x” is the input and the entire “f(x)” represents an output.
That means the last two options are wrong. They’re purposely switched up in what they say.

The correct answer is the second one, because that one is saying “each input will be paired with exactly one output.”

Answer w/ explanation !!<br><br><br> solve for x

So you’re gonna do

5x + 2 = 48
-2 -2

5x = 46
and then divide 5 by both sides and you get x = 9.2 (IF YOU GET IT WRONG IM VERY SORRY BECAUSE IM ALSO LEARNING THIS)

Plz help...it’s a math question and I suck at math would mean a lot to me thx <3

Answer:

Read below

Step-by-step explanation:

11. YX = 4.5

RQ corresponds to ZY. If RQ is 4 and ZY is 3, then ΔQRP was dilated by 0.75 to form ΔYZX. (3/4 = 0.75). Using this knowledge, we can find the length of YX by multiplying 6 by 0.75. (YX corresponds to QP). 6 × 0.75 = 4.5.

12. 55°

All of a triangle's angles must add up to 180°. ∠Q is 88°. ∠Z is 37°. ∠Z is congruent to ∠R because corresponding angles in similar triangles are congruent. So, 88° + 37° = 125°. We need to get to 180°, so 180° - 125° = 55°.

13. 4.2

BC corresponds to DF. We need to find the scale factor, so divide 2.7 by 3.6. That equals 0.75. AC corresponds to EF. EF is 5.6, so multiply 5.6 by 0.75. That equals 4.2.

I hope this helps :))

The system of equations n=m and n=4m is the point (0,0). which of the following statements is true.

Katyanochek1 [597]

<h3>Answer:</h3>

A. (0,0) is a solution to n=m and to n=4m.

<h3>Step-by-step explanation:</h3>

The equations can be solved by any of the usual means. Using substitution, we have ...

... m = n = 4m

... m(4 -1) = 0 . . . . subtract the left side

... m = 0 . . . . . . . . divide by 3

... n = m = 0

The solution is (m, n) = (0, 0).

Integrate dx/sin3xtan3x

disa [49]

$\displaystyle\int\frac{\mathrm dx}{\sin3x\tan3x}=\int\frac{\cos3x}{\sin^23x}$

Set $u=\sin3x$ , so that $\mathrm du=3\cos3x\,\mathrm dx$ . Then the integral is

$\displaystyle\frac13\int\frac{\mathrm du}{u^2}=-\frac1{3u}+C=-\frac1{3\sin3x}+C=-\frac13\csc3x+C$

Or, if you meant exponents in place of coefficients,

$\displaystyle\int\frac{\mathrm dx}{\sin^3x\tan^3x}=\int\csc^3x\cot^3x\,\mathrm dx=\int\csc^2x\cot^2x\csc x\cot x\,\mathrm dx$

Let $u=\csc x$ , so that $\mathrm du=-\csc x\cot x\,\mathrm dx$ , and use the fact that $\csc^2x=\cot^2x+1$ to get

$\displaystyle-\int u^2(u^2-1)\,\mathrm du=\int (u^2-u^4)\,\mathrm du=\frac13u^3-\frac15u^5+C$
$=\dfrac13\csc^3x-\dfrac15\csc^5x+C$
