Answer:

The solution to this system of equations is (x,y) = (-6, 8).

Step-by-step explanation:

Since the number of equations and number of variables is the same, there is only one solution. Let y = -\frac{1}{3}\cdot x + 6 and x = -6, the solution of this system is found by evaluating the first function, that is:

y = -\frac{1}{3}\cdot (-6)+6

y = 2+6

y = 8

The solution to this system of equations is (x,y) = (-6, 8).

Answer:

(-6,8) is the answer using substitution method.

The length of a rectangle is twice its width. if the perimeter of the rectangle is 54 ft , find its length and width.
polet [3.4K]
Let w be the width.

2(2w) + 2w = 54.

4w+2w = 54
6w=54.
w=9
So length equals twice that...I think you can solve that on your own. xD

Help please i need the answer quick class ends soon and need a hight grade
Luda [366]

Answer: 14

Step-by-step explanation:

Step 1: Substitute the x and y values:

\frac{4^3-2^3}{4}

Step 2: Find 4 to the power of 3.

4 x 4 x 4 = 64

Now find 2 to the power of 3

2 x 2 x 2 = 8

Step 3: Subtract the two values as mentioned in the equation:

64 - 8 = 56

Step 4: Now divide 56 by 4 as mentioned in the equation.

56 ÷ 4 = 14

And... 14 is the answer!

Hope this helps :)

Answer:

17) 750/9 and 18) 364

Step-by-step explanation:

17. Summation of 75*(0.1)^i from i=0 to infinity, that is equal to 75*(Summation of (0.1)^i). Summation of (0.1)^I is a geometric series with a sum of 1/(0.9)=10/9. Hence the series have a sum equal to 75*(10/9)=750/9

18) It's a series with sum=1+3+9+27+81+243=364
