Solve the equation for x. 1 6 (2x − 12x) = 30 A) −12 B) −15 C) −18 D) −24
lubasha [3.4K]

\frac{1}{6}*(2x-12x) = 30

\frac{1}{6}*(-10x) = 30

\frac{-10}{6}x = 30

\frac{-5}{3}x = 30

\frac{5}{3}x = -30

x = -30/\frac{5}{3} = -30 * \frac{3}{5}

x = -18

the correct answer is C

QUESTION 1
wlad13 [49]

Based on the information given, the simple interest rate that will be earned will be 13.6%.

  • Principal = $5250
  • Simple Interest = $6500- $5250 = $1250
  • Time = 21 months = 1.75 years.

Simple Interest = PRT / 100

1250 = (5250 × 1.75 × R) / 100

Cross multiply

125000 = 9187.5R

R = 125000 / 9187.5

R = 13.6%

The value of n from the set {6, 7, 8, 9} that holds true for 4n − 12 < 2n + 2 is .
IrinaVladis [17]

Answer:

6

Step-by-step explanation:

4n - 12 < 2n + 2 is for n=6

4×6 -12 < 2×6 +2

24 - 12 < 12 + 2

12 < 14 correct

for n=7

4×7 - 12 < 2×7 + 2

16 < 16 incorrect

for n=8

4×8 - 12 < 2×8 + 2

20 < 18 incorrect

for n=9

4×9 - 12 < 2×9 + 2

24 < 20 incorrect

so, only for n=6 is the expression true.

Given that (x + 2) is a linear factor of the polynomial x3 + 4x2 + x – 6, what are the other two linear factors?A. (x – 1) and (
kkurt [141]

The other two linear factors of the polynomial x³ + 4x² +x -6 are; Choice A: (x – 1) and (x + 3)

<h3>Polynomial division</h3>

By ling division of polynomials, it follows that the division of polynomial x³ + 4x² +x -6 by x +2 yields the quadratic expression;

  • x² + 2x -3.

On this note, the factorisation of the quadratic expression above yields factors;

  • (x – 1) and (x + 3)
