Answer:
1
Step-by-step explanation:
-2(x-4)+1=7
First Distribute the -2.
-2x+8+1=7
Subtract the 8 and 1 from the whole equation.
-2x=-2
Divide both sides of the equation by -2.
x=1
I hope this helps!
1/2 of 2 means you're taking a half of 2. Which 1.
Hello
<span>y= e^x (x^2 -7x +13)
y' = (</span>e^x)' (x^2 -7x +13)+e^x (x^2 -7x +13)'
y' = e^x(x^2 -7x +13)+e^x (2x-7)
y" = e^x(x^2 -7x +13)+e^x (2)
y"=e^x(x^2 -7x +15)
The answer is a rectangle or a square.
Let x=small rugs and y=medium rugs. It takes 8 hours to dye a small rug, so you would write 8x. It takes 12 hours to dye a small rug, so you would write 12y. Those two would need to be added together. The dyer needs to dye at least 22 rugs in 240 hours, so you would need a less than or = to sign.
I'm not sure which choice has the line beneath, indicating that the sign is a "less than or equal to" sign, but the answer is gonna be either C or D.
8x+12y≤240, or 12y+8x<span>≤240</span>
