Here you have 2 linear equations and are to solve this system. Both equations have already been solved for y, so you can set one of them = to the other one:

-2x+11 = -3x+21.

Then 3x-2x = 21 - 11, or x = 10 (answer)

Find y by subst. x = 10 into either of the given equations.

Solution is then (10, ? )

Which polynomial lists the powers in descending order? A. –10 + 4x3 – 4x5 + 2x4 + x7 B. x7 – 4x5 + 2x4 + 4x3 – 10 C. x7 + 4x3 +

The answer for the exercise shown above is the option B, which is: $x^{7} -4 x^{5} +2 x^{4} +4 x^{3}- 10$
The explanation is shown below:
To list the powers of the polynomial given in the problem above in descending order, you must write the terms from the highest degree to the lowest degree. You have that the highest degree is $7
$ and the lowest degree is $0
$ (Because $-10 x^{0} =-10(1)=-10$ . Therefore, you have that the correct option is the option B.

How many tenths make up 4 wholes?<br>

NikAS [45]

Divide 4 by 1/10.

So, 4 ÷ 1/10 becomes 4 x 10/1.

We know that 4 x 10/1 = 40/1 = 40.

1. Not random. Because you are asking people if they like ICE CREAM in a ICE CREAM shop.
2. Not random. Because they are serving a small controlled group.
3. Not random. Because you go shopping at Publix because you like it.
4. Random. Because you don't choose who is home or not.

Sam is placing rope lights around the edge of a circular patio with a diameter of 18 feet. The lights come in lengths of 54 inch

andrew-mc [135]

You can find the circumference of the circle with the circumference equals 2pir.
circumference=2pi9
circumference=18pi
circumference=56.55 feet
you can then turn the feet into inches by multiplying by 12
(56.55 feet)x(12inches/foot)=678.58 inches
then divide 678.58 inches by 54 inches to find how many light strands are needed.
(678.58 inches)/(54 inches/strand)=12.57 strands
