1/10, 3/20, 5/30, 7/40 arithmetic sequence geometric sequence neither
Zina [86]
If a, b, c is an arithmetic sequence then a + c = 2b

a = 1/10; b = 3/20, c = 5/30

a + c = 1/10 + 5/30 = 3/30 + 5/30 = (3+5)/30 = 8/30
2b = 2 · 3/20 = 3/10 = 9/30

8/30 ≠ 9/30

If a, b, c is a geometric sequence then ac = b²

ac = 1/10 · 5/30 = 1/2 · 1/30 = 1/60
b² = (3/20)² = 9/400

1/60 ≠ 9/400

Subtract the following polynomials, then place the answer in the pro
mars1129 [50]

Answer:

  • 8x^2+5.8xy-1.9

Explanation:

The polynomial subtraction is:

  • (-6.7x^2+2.3xy + 5.2)-(-14.9x^2-3.5xy+7.1)

The ruls to add or subtract polynomials is to add or subtract like terms.

LIke terms are the terms with the same variables each raised to the same power. So, the like terrms for those two polynomilas are:

  • -6.7x² and -14.9x²,
  • +2.3xy and -3.5xy,
  • 5.2 and 7.1

The next step is to use the distributive property: you must distribute the subraction symbol before the parenthesis through every term inside the parenthesis. For this, remember the rule of the signs:

  • When you multiply the negative sign before the parenthesis, the sign of each term inside the parenthesis will be changed (negative times positive = negative, negative times negative = positive)

So, the result is:

(-6.7x^2+2.3xy + 5.2)-(-14.9x^2-3.5xy+7.1)=-6.7x^2+2.3xy + 5.2+14.9x^2+3.5xy-7.1\\ \\ -6.7x^2+14.9x^2+2.3xy+3.5xy+5.2-7.1\\ \\8.2x^2+5.8xy-1.9

And that is ordered in descending powers of x (x² has order 2, xy has order 1 on each variable, and the constant terms have order 0).

Which of the following is a point-slope equation of a line that passes through the points (-1, 4) and (8,-2)?
yan [13]

Answer:

B

Step-by-step explanation:

We want to find the point-slope equation of a line that passes through the points (-1, 4) and (8, -2).

Point-slope form is given by:

y-y_1=m(x-x_1)

Where <em>m</em> is the slope and (<em>x₁, y₁</em>) is a point.

So, let's find the slope of the line first. We can use the slope formula:

\displaystyle m=\frac{\Delta y}{\Delta x}=\frac{-2-4}{8-(-1)}=\frac{-6}{9}=-\frac{2}{3}

We can choose (-1, 4) as our point. So, (<em>x₁, y₁</em>) = (-1, 4).

Substitute:

\displaystyle y-(4)=-\frac{2}{3}(x-(-1))

Simplify:

\displaystyle y-4=-\frac{2}{3}(x+1)

Therefore, our answer is B.
