Answer:
steps below
Step-by-step explanation:
5th level of Pascal triangle: 1,5,10,10,5,1
(1+2x)⁵ = 1*1⁵*(2x)⁰+5*1⁴*2x+10*1³*(2x)²+10*1²*(2x)³+5*1¹(2x)⁴+1*1⁰*(2x)⁵
= 1 + 10x + 40x² + 80x³ + 80x⁴ + 32x⁵ .. (1)
(1-2x)⁵ = 1 - 10x + 40x² - 80x³ + 80x⁴ - 32x⁵ .. (2)
(1)+(2): (1+2x)⁵ + (1-2x)⁵ = 160x⁴ + 80x² +2
a + bx + cx ?? suppose it's ax⁴ + bx² + cx, if you have other set up.. adjust by yourself
<u>a = 160, b = 80, c = 2</u>
Answer:
step 3 is incorrect and x = 10/ 8
Answer:
8,000
Step-by-step explanation:
the nearest thousand is 8,000 as it is past 7,500.
The two lines coincide. The two equations have the same slope and intercept. If you multiply the second equation by 3, you’ll get the first equation.
Answer:
Slope = -1/4
Step-by-step explanation:
Slope = (-8 + 5)/(0 + 12) = -3/12 = -1/4
