Since n=5, take the 6th row of Pascal Triangle: (a+b)⁵:

(a+b)⁵ = a⁵+5a⁴b+10a³b²+10a²b³+5ab⁴+b⁵.

But a= 2x and b=y, plug in:

(2x)⁵ + 5(2x)⁴y + 10(2x)³y² + 10(2x)²y³ + 5(2x)y⁴ +y⁵

32x⁵ + 80x⁴y +80x³y² + 40x²y³ + 10xy⁴ + y⁵

The 3rd term has a:
coefficient = 80
power of x= 3
power of y =2

What is the slope of the line that goes through the points (1,-5) and (4,1)?
lesya692 [45]

Answer: m = 2

Step-by-step explanation:

What we know:

  • The slope needs to pass through the points (1, -5) and (4, 1)
  • There are 4 potential slopes given to us- only one is correct
  • We need to find the slope and make sure it is an option

How to solve:

By using the slope equation and the two points given to us, we can calculate the slope.

Process:

  • Set up equation                                                 (y2 - y1) / (x2 - x1)
  • Substitute                                                            (1 +5 ) / (4 - 1)
  • Simplify                                                                6 / 3
  • Simplest form                                                      2/ 1 =

Slope =                                                                          2

Solution: m = 2

A standardized test that colleges use to make admissions decisions is the _____.
Aloiza [94]

Answer:

D

Step-by-step explanation:

EXPLORE test is the college test ACT's "prep" version mostly for 8th and 9th graders.

ASVAB (Armed Services Vocational Aptitude Battery) test is used for military entrance exam.

PLAN is also like EXPLORE that it is a "prep" test for ACT but usually given to sophomore (10th grade) students. This has been discontinued from 2014, though.

SAT is a standardized test administered by College Board and is a widely used common Undergraduate University admissions exam. Colleges use this to make admissions decisions.

Thus, D is the correct choice.
