Divide the polynomials using long division.

Mathematics
1 answer:
Basile [38]3 years ago
3 0

Answer:

1.x+1 with -5 as the remainder. 2.4x+15 with 40 as the remainder. 3.2x-16 with 68 as the remainder.

Step-by-step explanation:

Do the division house thing. put x square plus 4x minus 2 inside. multiply by x and put it on the roof. you will have x square plus 4x minus x square minus 3x. the x squares cancel out. Bring down the -2 and 1x from the subtraction before. u will have 1x-2. multiply by 1 to x-3. the x cancels and -2-3 equals -5. so 5 is the remainder. do the same house, and roof structure. Multiply by 4x...put on roof. the 4x squares cancels out. and 4x times 2 equals 8x. 8x+7x equals 15x. bring down the 10. multiply by 15. the x cancels. then 10+30(from 15x2) equals 40. 40 is the remainder. do the same ti tge third. 2x times x equals 2x square. the 2x squares cancels. multiply 2x by 5. -10x-6x=-16x. bring down the -12. multiply by -16. -16x+16x cancels out. since 16times -5 equals 80, bring the 18 down. it will be -12+80 which equals 68..positive 68 as the remainder. hope i helped

R/16 + 6 = 7 pLEASE HELP WITHIN A HOUR OR TWO
cestrela7 [59]

Solution:

<u>Simplify the equation and solve for r.</u>

  • r/16 + 6 = 7
  • => r/16 = 7 - 6
  • => r/16 = 1
  • => r = 16

The value of r is 16.

<u>Check:</u>

  • r/16 + 6 = 7
  • => 16/16 + 6 = 7
  • => 1 + 6 = 7
  • => 7 = 7 (Proved correct)

What is the graph of the inequality 3x+2y&gt;-5
Doss [256]

Answer:

The graph with solution is shown below.

Step-by-step explanation:

We need to find the x-intercept and y-intercept for given equation.

For  x-intercept , substitute y=0

Considering inequality sign as equality and simplifying,

3x+2y=-5\\3x+0=-5\\x=-\frac{5}{3} , point is (-\frac{5}{3} ,0)

Similarly,

For y-intercept , substitute x=0

We get,

3x+2y=-5\\0+2y=-5\\y=-5/2 , point is (0,-\frac{5}{2})

We locate this two points on the graph now and join them.

The joining line will be dotted as the inequality has just 'greater than' symbol. The region above the dotted line is the solution to graph.
