Answer:

1. Substitute y = -3x +4 for y in the first equation

2. Combine like terms and isolate x

3. Substitute in x into the 2nd equation to get y

Step-by-step explanation:

1. Substitute y = -3x +4 for y in the first equation

2x- (-3x+4) = 6

2. Combine like terms

5x -4 = 6

5x -4 +4 = 6+4

5x=10 Divide by 5 to isolate x

5x/5 =10/5

x=2

3. Substitute in x into the 2nd equation to get y

y = -3x +4

y = -3(2) +4

y = -6+4

y=-2

Alex787 [66]

Answer

8√2

Explanation

Simply: 4√2 + 7√2 - 3√2

Let √2 = x

4√2 + 7√2 - 3√2 = 4x + 7x - 3x

= 11x - 3x

= 8x

Substituting x with √2

4√2 + 7√2 - 3√2 = 8√2

Northwest Molded molds plastic handles with a variable cost of $1.00 per handle. The fixed cost to run the molding machine is $2

ASHA 777 [7]

Answer:

To break even it must be molded 1280 handles weekly.

The profit if 1500 handles are produced and sold is $440

Step-by-step explanation:

To break even, the amount of total cost must be the same as the amount of revenues.

Total Cost is Fixed cost plus unitary variable cost multiplied by the produce quantity.

Total cost= FC + vc*Q

Where

FC=Fixed cost

vc=unitary variable cos

Q=produce quantity

Revenue= Price * Q

Break even FC + vc*Q=Price * Q

Isolating Q

FC=(Price * Q)-(vc*Q)

FC=(Price-vc) * Q

Q= FC/(Price-vc)

Q= $2560/($3.00-$1.00)=1280

If we sold 1500 handles

Profit = Revenue- Total cost =(Price * Q)-(FC + vc*Q)

P=$3.00 *1500-$2560 - $1.00*1500=

P=$4500-$2560-$1500=440

ELEN [110]

Answer:

your answer is 58 sq. ft.

Step-by-step explanation:

4 1/2 × 13

Covert the mixed number into an improper fraction

4 1/2 = 9/2

Then make 13 into a fraction

13/1

Now multiply the fractions

9 × 13 = 117

2 × 1 = 2

Next change the improper fraction into a mixed number

58 1/2

Next change it into a decimal

58.5

Lastly round it and we have the answer
