Answer:

y=-3x+3..........(1)

6x+2y=6

putting value of y

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

6x-6x+6=6

o=0

sorry I do not get answer

anastassius [24]

Answer:

2(3(8))+2(8)=64

Step-by-step explanation:

Here, w represents the width of the rectangle,

∵ length of the rectangle is 3 times the width of the rectangle,

So, length = 3w,

Since, the perimeter of a rectangle, P = 2(length + width)

= 2(w + 3w)

= 2w + 2(3w)

If P = 64 feet,

⇒ 2w +2(3w) = 64

⇒ 2w + 6w = 64

⇒ 8w = 64

⇒ w = 8

Verification :

P = 2(8) + 2((3(8)) = 16 + 48 = 64 feet

Hence, the first step that should be taken to verify that the width of the rectangle is 8 is 2(3(8))+2(8)=64

Note : a solution obtain from an equation is verified by substituting the value in the equation.

enot [183]

Answer:

$f(x)=3.95sin(\frac{\pi}{12}x)+4.35$

Step-by-step explanation:

Recall:

Sinusoidal Function -> $f(x)=a*sin(bx+c)+d$
Amplitude -> $a$

Period -> $\frac{2\pi}{|b|}$
Phase Shift -> $-\frac{c}{b}$

Vertical Shift/Midline -> $d$

Given:

Amplitude -> $a=8.3-4.35=3.95$
Period -> $\frac{2\pi}{|b|}=\frac{2\pi}{|24|}=\frac{2\pi}{24}=\frac{\pi}{12}$
Phase Shift -> $-\frac{c}{b}=-\frac{0}{24}=0$
Vertical Shift/Midline -> $d=\frac{8.3+0.4}{2}=\frac{8.7}{2}=4.35$

Conclusion:

The equation that models the situation is $f(x)=3.95sin(\frac{\pi}{12}x)+4.35$

Hope this helped! I've attached a graph of the function so you can understand it better!
