Which ordered pair is the best estimate for the solution of the system of equations? y=32x+6 y=14x−2
Marysya12 [62]

since y = both rewrite as

32x+6 = 14x-2 and solve for x

32x +6 = 14x-2

add 2 to both sides:

32x +8 = 14x

subtract 32x from both sides:

8 = -18x

divide both sides by -18

x = 8/-18 which reduces to -4/9

now use that for x and solve for Y

32(-4/9) +6 = -74/9

ordered pair:

(-4/9, -74/9)

7x² + 6x - 1<br> Algebra 3|factoring
GaryK [48]

Answer:

(7 x - 1) (x + 1)

Step-by-step explanation:

Factor the following:

7 x^2 + 6 x - 1

Factor the quadratic 7 x^2 + 6 x - 1. The coefficient of x^2 is 7 and the constant term is -1. The product of 7 and -1 is -7. The factors of -7 which sum to 6 are -1 and 7. So 7 x^2 + 6 x - 1 = 7 x^2 + 7 x - x - 1 = (7 x - 1) + x (7 x - 1):

(7 x - 1) + x (7 x - 1)

Factor 7 x - 1 from (7 x - 1) + x (7 x - 1):

Answer: (7 x - 1) (x + 1)

What is the difference of the rational expressions below? 4/x^3 - 2x-1/3x
Paul [167]

Answer:

C

Step-by-step explanation:

Given

\frac{4}{x^3} - \frac{2x-1}{3x}

Multiplying the numerator/ denominator of the first fraction by 3 and the numerator/denominator of the second fraction by x² will ensure that the fractions have a common denominator.

= \frac{3(4)}{3x^3} - \frac{x^2(2x-1)}{3x^3}

= \frac{12}{3x^3} - \frac{2x^3-x^2}{3x^3} ← combine terms on numerator

= \frac{12-2x^3+x^2}{3x^3}

= \frac{-2x^3+x^2+12}{3x^3} → C
