The Domain is all real numbers, and since the graph is translated 1 down and flipped across the x-axis, the Range is all real numbers less than or equal to -1.

F(x)=4x-3<br> G(x)=x^3+2x<br> Find (f-g)(x)
dexar [7]
You gotta remember that (f-g)(x) means f(x) - g(x).

So, in this case, f(x) is [4x - 3], g(x) is [x^3 + 2x].
So that : f(x)-g(x) = [4x-3] - [x^3+ 2x] = -x^3 + 4x - 2x - 3 = -x^3 + 2x - 3

Solve x2 − 10x = −13.
aev [14]

Answer:

B

Step-by-step explanation:

First, let's rearrange the given equation into something more recognizable. If we add 13 to both sides, we now have the polynomial x^{2}-10x+13. We can now use the quadratic formula to solve.

Remember that the quadratic formula is

\frac{-b+/-\sqrt{b^{2}-4ac } }{2a}

Substitute the numbers from the equation into the formula.

\frac{-(-10)+/-\sqrt{(-10)^{2}-4(1)(13) } }{2(1)}

Simplify:

\frac{10+/-\sqrt{100-52} }{2}

\frac{10+/-\sqrt{48} }{2}

Here, I'm going to assume that there was a mistype in option B because if we divide out the 2 we end up with 5+/-\sqrt{48}.

Hope this helps!

Can someone help me with this? I’m stuck. Thank you!
Leto [7]

Answer:

31°

3

108°

Step-by-step explanation:

The measure of angle ADB is congruent to the measure of angle CBD, so it is equal to 31°.

4x = 12

divide by 4 on both sides and you are left with x=3

angle A is congruent to angle C, so it is equal to 108°.

Hope this helps!
