What is the sum of 6x3+8x2-2x+4 and 10x3+x2+11x+9
AleksAgata [21]

Answer:

16x³ + 9x² + 9x + 13

Step-by-step explanation:

Given

6x³ + 8x² - 2x + 4 and 10x³ + x² + 11x + 9

Sum the 2 expressions by adding like terms, that is

= (6x³ + 10x³) + (8x² + x²) + (- 2x + 11x) + (4 + 9)

= 16x³ + 9x² + 9x + 13

Which line is perpendicular to the line y=-1/3x-2 and passes through point (1,4)
xxMikexx [17]

Answer:

Option 3)  y = 3x+1

Step-by-step explanation:

<u><em>Given equation is:</em></u>

y = -\frac{1}{3} x -2

Perpendicular => <u><em>It will have a slope of negative reciprocal to this slope</em></u>

So the  ⊥ line has a slope = m =  3

Now,

Point = (x,y) = (1,4)

So, x = 1, y = 4

<u><em>Putting this in slope intercept form to get b</em></u>

=> y = mx+b

=> 4 = (3)(1) + b

=> b = 4-3

=> b = 1

<u><em>Now, Putting m and b in the slope intercept form to get the required equation:</em></u>

=> y = 3x+1
