ANSWER: 7/6

step 1: Simplify both sides of the equation.
step 2:Subtract 2/3 from both sides.
step 3: Multiply both sides by 7/(-1).

Solve the following system:y = x + 3
2x + y = 9

(2, 5)
(5, 2)
(−2, 5)
(2, −5)

Answers

Hi,

y = x+3
2x+y = 9

2x+(x+3) = 9
2x+x+3 = 9
3x+3 = 9
3x = 9-3
3x = 6
x = 6/3
x = 2

y = x+3
y = 2+3
y = 5

Answer:

(x,y) = (2,5)
ahhh easy:) all we have to do is plug in y
sooo this question becomes 
2x + x + 3 = 9 
we add the xs and they become 3x
soooo
3x + 3 = 9 
now subtract 3 from both sides
3x +3 = 9 
     - 3 = -3 
they cancel out on the left hand side and the right side of the equal sign becomes a 6 
sooooo
3x = 6 
divide both sides by 3 
3x = 6 
÷3 = ÷ 3
the 3s on the left side cancel out
and the right side becomes 2
sooooo
x = 2 
but before we can answer this completely we plug it into our first equation
soooo
y = x + 3 
to this 
y = 2 + 3 
so y = 5
x = 2 
y = 5 
coordinates?

A round cake pan that is 2 inches deep and has a 7 inch diameter a 6 inch x9 inch rectangular cake pan that is 2 inches deep a. which of these pans has the larger volume justify your answerb. excluding the bottom of the cake what is the surface area of each cake that will be covered by frosting justify your answer

Answers

a) Pan 2 has a larger volume because:

Pan 1:

Circle area = pi x r^2
7/2 = 3.5
3.5 x 3.5 = 12.25inch^2
12.25 x pi = 38.48451
38.48451 x 2 = 76.96902inch^3 (76.97inch^3 to 2dp)

Pan 2:

6 x 9 = 54inch^2
54 x 2 = 108inch^3

b)

Pan 1:

Surface area covered =  60.48inch^2 (2dp) because:

Circle area = pi x r^2
7/2 = 3.5
3.5 x 3.5 = 12.25inch^2
12.25 x pi = 38.48451inch^2

Circumference = pi x diameter
pi x 7 = 21.9911486
21.9911486inch^2

21.9911486 + 38.48451 = 60.4756586inch^2

Pan 2:

Surface area covered = 114inch^2 because:

Bottom:
6 x 9 = 54inch^2

2 longer sides:
2 x 9 = 18
18 x 2 = 36inch^2

2 shorter sides:
2 x 6 = 12
12 x 2 = 24inch^2

Total = 54 + 36 + 24 = 114inch^2

(Hope this helps.)
