What is the degree and classification or the following 8x^2y + 5xy

2 answers:

I believe the degree of this is 3, assuming that y isn't part of the exponent, and this is a binomial because it has 2 terms.

You need to look at each term and find the degree by adding the exponents of each variable in it. The largest degree is the degree of the polynomial.

8x²y has a degree of 3 (x has an exponent of 2, y has 1, and 2+1=3)
5xy has a degree of 2 (x has an exponent of 1, y has 1, and 1 + 1 = 2)
So, degree = 3

The polynomial has 2 terms, so it's binomial ← classification

Which of the following graphs shows the solution set to 2x < 6 and 3x + 2 > -4?

Ilya [14]

Answer:

The third picture

Step-by-step explanation:

Solve for x in both equations

2x<6

Divide both sides by 2:

x<3

3x+2>-4

Subtract 2 from both sides:

3x>-6

Divide both sides by 3:

x>-2

There is this trick you can use when x is on the left side of the equation to find out which way to shade in you graph. Keep in mind this is only for the left side, it will not work if your variable is on the right.

When the symbol is facing left < then shade left, imagine it is pointing which way to shade. x<3 is represented by the 3 picture on the left. When the symbol is facing right > then shade right, again it is pointing which way to shade. x>-2 is represented by the 3 picture on the right.

The circles are not filled in because the symbol is < and > rather than $\leq and \geq$ . When it is greater than or equal to or less than and equal to (represented by the line under the symbol), then the circle is shaded in.

three uses 8 pieces of glass per square foot to make a stained glass window how many pieces of glass will he need to make a wind

yanalaym [24]

1 foot = 12 inches
864/12=72 The window is 72 square feet.
A man uses 8 pieces of glass per square foot to make a stained glass window. So he needs to use 72*8=576 pieces of glass.

The diameter of a bacteria colony that doubles every hour is represented by the graph below. What is the diameter of the bacteri

Nady [450]

Do you notice anything strange about those points ?

(0, 1),
(1, 2),
(2, 4),
(3, 8).

The y-coordinate of each point is (2) raised to the power of the x-coordinate.

First point:   x=0, y=2⁰ = 1
Second point: x=1, y=2¹ = 2
Third point:    x=2, y=2² = 4
Fourth point: x=3, y=2³ = 8

The equation of the curve appears to be

   y = 2 ^ x .

So, after 10 hours, x=10, and y = 2¹⁰ = 1,024 .
