Answer:

None

Step-by-step explanation:

The solution to a system of equations given graphically is at the point of intersection of the 2 lines.

In this case the lines are parallel and never intersect.

Thus the system has no solution.

Solve 9x^2 + 12x – 24 = 0 using the quadratic formula.

Nataliya [291]

Quadratic formula = (-b +- sqrt(b^2 - (4ac))) / 2a

$\frac{ -12 + \sqrt{(12)^2 -((4)(9)(-24))}}{2(9)}$

and

$\frac{ -12 - \sqrt{(12)^2 -((4)(9)(-24))}}{2(9)}$

then simplify and solve

What is (f⋅g)(x)? f(x)=x^2−3x+2 g(x)=x^3−8 Enter your answer, in standard form, in the box. (f⋅g)(x)=

uysha [10]

Answer:

$f(g(x))=x^{6}-19x^{3}+90$

Step-by-step explanation:

We have been given the following equations;

f(x)=x^2−3x+2

g(x)=x^3−8

We are required to determine the composite function (f⋅g)(x). This simply means that we shall substitute the function g(x) in place of x in the function f(x);

$f(g(x)) = g(x)^{2}-3g(x)+2\\\\f(g(x))=(x^{3}-8)^{2}-3(x^{3}-8)+2\\\\f(g(x))=x^{6}-16x^{3}+64-3x^{3}+24+2\\\\f(g(x))=x^{6}-19x^{3}+90$

Fraction to ten exponent of 1

Nina [5.8K]

I'm guessing this means there is 10 with an exponent of one. In that case, it is just 10. So the fraction would be 1/1.

Verify<br> (2cos2x)/(sin2x) - cotx - tanx = -2tanx

lana66690 [7]

Remember:

$\boxed{sin(2x)=2.sinx.cosx}\\
\\
and\\
\\
\boxed{cos(2x)=cos^2x-sin^2x}$

$\frac{2cos2x}{sin2x}-cotx-tanx=\\
\\
\frac{2(cos^2x-sin^2x)}{2sinx.cosx}-\frac{cosx}{sinx}-\frac{sinx}{cosx}=\\
\\
\frac{cos^2x-sin^2x}{sinx.cosx}-\frac{cosx}{sinx}-\frac{sinx}{cosx}=\\
\\
\frac{cos^2x-sin^2x-cos^2x-sin^2x}{sinx.cosx}=\\
\\
\frac{-2sin^2x}{sinx.cosx}=\\
\\
\frac{-2sinx}{cosx}=-2.tanx$
