-7x-9y=-8

5x+6y=4

-35x-45y=-40

35x+42y=28

-3y=-12

y=4

5x+6(4)=4

5x+24=4

5x=-20

x=-4

(-4,4)

Hope this helps.

If f(x) =3x-5 them find values of f(3) and f(-7). please explain step by step​
LenKa [72]

Answer:

f(3) = 4

f(-7) = -26

Step-by-step explanation:

Hi there!

f(x) =3x-5

To find f(3), replace every x with 3:

f(3) =3(3)-5\\f(3) =9-5\\f(3) =4

Therefore, f(3)=4.

f(x) =3x-5

To find f(-7), replace every x with -7:

f(-7) =3(-7)-5\\f(-7) =-21-5\\f(-7) =-26

Therefore, f(-7)=-26.

I hope this helps!

A cylindrical can has a volume of 2in^(3). Express the surface area of the can as a function of its radius,r.
noname [10]
V=2 \text{ in}^3\\
A=2\pi r (r+h)\\
h=?\\\\
V=\pi r^2h=2\\
\pi r^2h=2\\
h=\dfrac{2}{\pi r^2}\\
A=2\pi r\left(r+\dfrac{2}{\pi r^2}\right)\\
\boxed{A=2\pi r^2+\dfrac{4}{r}}

When rewriting y = 2x + 1 in function notation, what do you replace with f(x)?
zmey [24]
You replace the y with f(x)
So it becomes f(x)=2x+1
