Scrat [10]

Answer:

x < -10/7

Step-by-step explanation:

Divide both sides by -7.  Because this divisor is negative, we must reverse the direction of the inequality sign, obtaining:

-7x   <   10

-----   <  -----

 -7         -7

Then x < -10/7

Answer:

  • 59; 44 & 68; 22.5; 44

Step-by-step explanation:

10.

  • x + 57 = 116
  • x = 116 - 57
  • x = 59

11.

  • y = 180 - 112 = 68
  • x= 180 - 2*68 = 44

12.

  • 4x + 10 = 180 - 2*40
  • 4x + 10 = 100
  • 4x = 90
  • x = 90/4
  • x = 22.5

13.

  • SG = HT/2

If (x ^ 3 + a * x ^ 2 + bx + 6) has (x - 2) as a factor and leaves a remainder 3 when divided by (x-3), find the values of a and
Fed [463]

The values of a and b are -3 and -1 respectively

x³ + ax ²+ bx + 6 has (x - 2) as a factor. Therefore,

(2)³ + a2²+ 2b + 6 = 0

8 + 4a + 2b + 6 = 0

4a + 2b = -14

x³ + ax ²+ bx + 6 leaves a remainder 3 when divided by (x - 3). Therefore,

(3)³ + a3²+ 3b + 6 = 3

27 + 9a + 3b + 6 = 3

9a + 3b = 3 - 33

9a + 3b = -30

<h3>Simultaneous equation:</h3>

4a + 2b = -14

9a + 3b = -30

2b = -14 -4a

b = -7 - 2a

Therefore,

9a + 3( -7 - 2a) = -30

9a - 21 - 6a = -30

3a = -30 + 21

3a = -9

a = -9 / 3

a = -3

4a + 2b = -14

4(-3) + 2b = -14

-12 + 2b = -14

2b = -14 + 12

2b = -2

b = -2 / 2

b = -1
