Answer and Step-by-step explanation:

I will solve your system by substitution.

x=2y+2;1=−2x+9y

Step: Solvex=2y+2for x:

Step: Substitute 2y+2 for x in 1=−2x+9y:

1=−2x+9y

1=−2(2y+2)+9y

1=5y−4(Simplify both sides of the equation)

1+−5y=5y−4+−5y(Add -5y to both sides)

−5y+1=−4

−5y+1+−1=−4+−1(Add -1 to both sides)

−5y=−5

−5y/-5=-5/-5

(Divide both sides by -5)

y=1

Step: Substitute 1 for y in x=2y+2:

x=2y+2

x=(2)(1)+2

x=4(Simplify both sides of the equation)

Answer:

x=4 and y=1

A line has a slope of -2/3 and passes through the point (–3, 8). What is the equation of the line?
ivann1987 [24]
 Note that an equation in the slope intercept form is y= mx + b where the slope is m and the y-intercept is b. Since we already know the slope (\frac{2}{3}, we can insert that for m.) y = \frac{2}{3} + b and this cancels out answer choice y = 6x - 2/3 and 8x - 2/3

Calculate the area of the shaded region.
Nostrana [21]

Let A be the area of the sector in the larger circle (radius 12 cm) whose central angle is subtended by the labeled arc with measure 45 deg, and let a be the area of the sector in the smaller circle (radius 8 cm) with the same central angle. The area you want is A-a.

We have

\dfrac A{\pi(12\,\mathrm{cm})^2}=\dfrac{45^\circ}{360^\circ}\implies A=18\pi\,\mathrm{cm}^2

\dfrac a{\pi(8\,\mathrm{cm})^2}=\dfrac{45^\circ}{360^\circ}\implies a=8\pi\,\mathrm{cm}^2

So the area of the shaded region is 18\pi-8\pi=10\pi.
