For the following linear equations, determine which inverse operation allows you to determine the solution of the equation. In y

VARVARA [1.3K]

Answer:

see explanation

Step-by-step explanation:

(1)

Given

$\frac{n}{5}$ = - 0.3

Since n is divided by 5 then use the inverse operation, multiplication.

Multiply both sides by 5 to clear the fraction

n = 5 × - 0.3 = - 1.5

(2)

Given

- 2n = 4 $\frac{1}{3}$ ← change to an improper fraction

- 2n = $\frac{13}{3}$

Since n is multiplied by - 2 then use the inverse operation, division.

Divide both sides by - 2

n = $\frac{13}{-6}$ = - $\frac{13}{6}$

How many distinct positive integer-valued solutions exist to the equation (x2 - 7x + 11)(x2 - 13x + 42) = 1

Anna35 [415]

Answer:

The given equation has TWO positive integer valued solutions, {6, 7}

Step-by-step explanation:

Here we are given two trinomial factors, each of which needs to be set equal to zero and in each case the resulting quadratic equation solved.

(x^2 - 7x + 11) has the coefficients {1, -7, 11}, and so the discriminant of this quadratic is b^2 - 4(a)(c), or 49 - 4(11), or 5.

Because this discriminant is positive, we know immediately that this quadratic has two real, unequal roots involving √5 (NO integer roots).

Next we focus on (x^2 - 13x + 42). The discriminant is b^2 - 4(a)(c), or

169 - 168, or 1. Again we see that there are two real, unequal roots:

+13 ± √1 +13 ± 1

x = --------------- or x = -------------

2 2

OR x = 14/2 = 7 (integer) or x = 12/2 = 6 (integer).

The given equation has TWO positive integer valued solutions, {6, 7}
