Answer:
−16y+6
Step-by-step explanation:
2(3−8y)
=(2)(3+−8y)
=(2)(3)+(2)(−8y)
=6−16y
=−16y+6
Answer:
72
Step-by-step explanation:
bacause the equation of area of square is a^2 and 12×12=144 so each side is 12 feet and the height is 6 making it 12×6 so 72 square feet
c = $10 + $0.50s
Assuming you bought 10 songs; then
c = $10 + $0.50(10)
= $10 + $5
c = $15
Bear in mind that the $10 is only a one-time membership fee, so, any purchase of songs after your payment of the $10 will be computed by $0.50s.
Answer:
3
Step-by-step explanation:
So we have the function:
![f(x)=3x^2+2x-5](https://tex.z-dn.net/?f=f%28x%29%3D3x%5E2%2B2x-5)
To evaluate the value of f(-2), substitute -2 for x. Thus:
![f(-2)=3(-2)^2+2(-2)-5](https://tex.z-dn.net/?f=f%28-2%29%3D3%28-2%29%5E2%2B2%28-2%29-5)
Square first:
![f(-2)=3(4)+2(-2)-5](https://tex.z-dn.net/?f=f%28-2%29%3D3%284%29%2B2%28-2%29-5)
Multiply:
![f(-2)=12-4-5](https://tex.z-dn.net/?f=f%28-2%29%3D12-4-5)
Now, subtract:
![f(-2)=8-5=3](https://tex.z-dn.net/?f=f%28-2%29%3D8-5%3D3)
So:
![f(-2)=3](https://tex.z-dn.net/?f=f%28-2%29%3D3)
And we're done!
