Simplest form of the expression is -2x - 7y

Step-by-step explanation:

Step 1: Simplify the expression following the BODMAS principle.

⇒ -(4x+y) + 2(x – 3y) = -4x - y + 2x - 6y

= -2x - 7y

4. The cosine function can be made to have the same values as the sine function for each angle by including a shifted _______ in

r-ruslan [8.4K]

Answer: Option D

phase

Step-by-step explanation:

By definition, the cosine function has the following form

$y = cos (x - \phi)$

Where $\phi$ is known as the phase angle

By definition the sinx function is equal to the cosx function with a phase shift of $\frac{\pi}{2}$

So if we have the function

$y = cos (x - \phi)$ and we want to transform it into the function $y=sin(x)$ then $\phi = \frac{\pi}{2}$

Finally

$y = cos(x - \frac{\pi}{2})=sin(x)$

the answer is the option D

Question 3: 12 points

Dvinal [7]

Answer:

$9x^{5}y^{5}$ yards.

Step-by-step explanation:

Given that the area of a rectangle (A) is $45x^{8}y^{9}$ square yards.

If the length of the rectangle (L) is given to be $5x^{3}y^{4}$ yards, then we have to find the width (W) of the rectangle in yards.

Now, A = L × W

⇒ $W = \frac{A}{L} = \frac{45x^{8}y^{9}}{5x^{3}y^{4}} = (\frac{45}{5})\times (\frac{x^{8}}{x^{3}}) \times (\frac{y^{9}}{y^{4}}) = 9x^{8 - 3}y^{9 - 4} = 9x^{5}y^{5}$ yards. (Answer)

Choose an equation for the relationship between the measures of the angles and arcs.

igor_vitrenko [27]

Because ∠2 is a diameter away from arc ST, ST is two times larger than ∠2. So, the answer is:

m∠2 = 1/2(mST)
