Answer:

x = 2

y = -8

Step-by-step explanation:

9x−2y=34 -------------------(I)

5x+2y=−6 -------------------(II)

Add equation (I) & (II) and so y will be eliminated and we could find the value of x.

(I) 9x - 2y = 34

(II) 5x + 2y = -6 {add}

14x = 28

x = 28/14

x = 2

Plug in x = 2 in equation (I)

9*2 - 2y = 34

18 - 2y = 34

-2y = 34 - 18

-2y = 16

y = 16/-2

y = -8

Which is the right answer?????

Inga [223]

Answer: A

Step-by-step explanation: put it into point slope-form

y-ysub1=m(x-xsub1)

m=slope=(-2-3)/(2-(-1))=-5/3

ysub1 is 3 and xsub1 is -1

so substitute: y-3=-5/3(x-(-1))

y-3=-5/2(x+1)

Please help me find the total area of the composite figure below (geometry)

Akimi4 [234]

Answer:

lw + $\frac{1}{2}$ × π × $(\frac{l}{2} )^{2}$ ⇒ Answer D is correct

Step-by-step explanation:

First, let us find the area of the semi-circle.

Area = $\frac{1}{2}$ × π × r²

Given that,

diameter of the semi-circle is ⇒ l

∴ radius ⇒ l / 2

Let us find it now.

Area = $\frac{1}{2}$ × π × r²

Area = $\frac{1}{2}$ × π × $(\frac{l}{2} )^{2}$

Secondly, let us find the area of the rectangle.

Area = length × width

Given that,

length ⇒ l

width ⇒ w

Let us find it now.

Area = length × width

Area = l ×w

Area = lw

And now let us find the total area.

Total area = Area of the rectangle + Area of the semi - circle

Tota area = lw + $\frac{1}{2}$ × π × $(\frac{l}{2} )^{2}$

a baker used 660 boxes of cake mix to make a wedding cake. if each box called for 3 eggs, how many dozen eggs were used to make

yanalaym [24]

We know there’s 660 boxes and each box called for 3 eggs, therefore:

660=3X

when divide both sides by 3 to isolate the x, which will tell us the amount of eggs used…

660/3 = 220
