Answer:

Alloy = 12.6 lbs.

Step-by-step explanation:

( 2/7 ) = ( Nickel /4.9)

Nickel = 1.4 lbs.

Ratio of Copper to Zinc:

( 9/7 ) = ( Copper /4.9)

Copper = 6.3 lbs.

Alloy = Zinc + Nickel + Copper

Alloy = 4.9 lbs. + 1.4 lbs. + 6.3 lbs.

Alloy = 12.6 lbs.

Line CD contains points A (4, 6) and B (−2, 6). What is the slope of the line CD?
vazorg [7]
The slope of the line given the points is calculated through the equation,
                                 m = (y2 - y1) / (x2 - x1)
Substituting the known values,
                                 m = (6 - 6) / (-2 - 4)   = 0
The slope of the given line is equal to 0 which means that it is a horizontal line.

liq [111]

Answer:

f(2) = 1

(1) = 2

(f(2)) = 2

Step-by-step explanation:

f(x) = x

(x) = 2x

f(2) = (2)

f(2) = 1

(1) = 2(1)

(1) = 2

(f(2)) = 2((2))

(f(2)) = 2(1)

(f(2)) = 2

Eli buys 8 gigabytes of memory for his computer he spends 392. whatbis the cost of 1 gigabyte memory
kotykmax [81]
If Eli spends $392 for 8 gigabytes of memory, then 8g=392, where g is a gigabyte of memory. All you have to do is to reduce the equation. In this case, divide both sides by 8 to get g=49. So the cost of 1 gigabyte of memory is $49.
