Use elimination to solve the system:
6x-4y=6
-6x+3y=0

Answers

Answer 1

Answer: 6x and -6x cancel each other out.
You are left with -1y=6
Therefore, y=-6

6x-4(-6)=6
6x+24=6
Subtract 24 from both sides.

6x=-18
Divide both sides by 6
X=-3

Final answers: x=-3 y=-6

Answer 2

Answer: 6x+4y=6
-6x+3y=0

7y=6
y=6/7

use one of the equations above i picked the first one
6x+4y=6
6x+4(6/7)=6
6x+24/7=42/7
6x=18/7
x=3/7

in other words, side1+side2>longest side

A. no longest side, so this is possible

B. longest is 17, 14+11>17 so it is possible

C. 414 is longest, 109+214<414 so this is NOT possible

D. 8 is longest, 2+7>8 so it is a possible triangle

Company 1 says that they will complete the job for $12 per foot of fencing. Company 2 says that they will charge you $4500 for the first 500 feet of fencing and $25 for each additional foot. Determine the cost of fencing for both companies .Remember that both companies need to charge 6.35% sales tax. SHOW WORK

Answers

So Company 1 charges $6,000 dollars for 500 feet of fence.
Company 2 only charges $4500/500 or $9.00/foot up to 500 feet.

The difference of 6,000 - 4500 = $1,500 so using Company two you will get 60 more feet of fence then both companies break even. After 500 ft
Company 1 only charges $12.00 dollars a foot and Company 2 charges $25.00 a foot.

So if you need 500 ft Company 1 costs 6,000 + 391.80 tax
Company 2 costs 4,500 +293.85 tax
Question does not ask how many feet is going to be needed?

The volume of a cube is 400 m3. Which statements are true about the same cube measured in cubic centimeters?

Choose all answers that are correct.

A.

The number representing the volume would decrease.

B.

The number representing the volume would increase.

C.

The actual volume would decrease.

D.

The actual volume would increase.

E.

The actual volume would stay the same.

Answers

$1 \ m^3=1000000 \ cm^3 \n \n400 \ m^3=400 * 100 00 00 \ cm^3=400000000 \ cm^3$

As you can see, the number representing the volume increased. We converted one unit to another but the actual value is the same - 400000000 cm³ is the same as 400 m³.

The correct answers are B and E.

2. If y varies inversely as x and
y = 3 when x = 5, find x when y = 2.5

Answers

Answer:

Step-by-step explanation:

From the law of variation,

y <> 1/x, where <> is the constant of proportionality. Therefore

y = k/x where k is a constant

3 = k/5 and k = 15

To find x when y = 2.5(5/2)

Go back to the second equation

y = k/x

5/2 = 15/x

When you cross multiply

5x = 30.

Divide through by 5,

x = 6.
