Answer: x=-3 and y = 11

Step-by-step explanation: x+y = 8 and x-y = - 14

From first solve y = 8-x and now Insert y to later

x -(8-x) = -14. x -8+x-14. 2x = -6 and x=-3. Y = 8-x = 11

A worker at a mill is loading 10-lb bags of flour into boxes to deliver to a local warehouse. Each box holds 4 bags of flour. If
Hunter-Best [27]

Answer: 100 boxes

Step-by-step explanation:

Hi, since 1 ton = 2,000 lbs

We have to divide 10lbs by 2000 to convert the lbs in tons.

1t/2000lb = xt / 10lb

10 /2000=0.005

0.005 ton = 10 lbs (1 bag)

Each box has 4 bags

0.005 ton x 4 = 0.02 ton

So each box weights 0.02 ton

Since we need 2 tons.

Using proportions:

0.02t/1 box= 2 t / x boxes

x = 2 / (0.02/1)

x = 100 boxes

Consider the function f(x) = 4x² - x + 3. What is f(1)?
zhannawk [14.2K]

Replace every x you see in the function with 1 and simplify.

Let x be 1.

f(1) = 4(1)^2 -(1) + 3

f(1) = 4(1) - 1 + 3

f(1) = 4 - 1 + 3

f(1) = 3 + 3

f(1) = 6

Done!
