Answer: 103/15

Step-by-step explanation:

We can simplify the right-hand side to be $2 \left(\frac{1}{3}+6 \right)=2 \left(\frac{19}{3} \right)=\frac{38}{3}$ .

This means we need to solve:

$\frac{1}{2}(5x-9)=\frac{38}{3}\\5x-9=\frac{76}{3}\\5x=\frac{103}{3}\\x=\boxed{\frac{103}{15}}$

Tanya runs a catering business. Based on her records, her weekly profit can be approximated by the function LaTeX: f\left(x\righ

Shtirlitz [24]

The function

$2x^2-44x-150$

is a parabola concave up, whose solutions are

$2x^2-44x-150=0 \iff x^2-22x-75=0$

from here, you can use the quadratic formula

$x_{1,2} = \dfrac{-b\pm\sqrt{b^2-4ac}}{2a}$

to find that the solutions of the parabola are $-3,\ 25$

So, the parabola is positive if $x$ (which wouldn't make sense in our case) or $x$

So, if Tanya caters 25 meals she breaks even, and starting with the 26th meal she will begin to profit.

Trigonometry Identities help please

sesenic [268]

theta is in the fourth quadrant where the cosine is positive.

the third side in the triangle = sqrt (4 - 2) = sqrt2

So sin theta = -sqrt2/2 = Second choice (negative because sine is negative in 4th quadrant)

tan theta = - sqrt2 / sqrt2 = -1
