One solution was found : t ≤ -13 (Last answer choice)

Pull out like factors :

-3t - 39 = -3 • (t + 13)

Divide both sides by -3

Remember to flip the inequality sign:

Solve Basic Inequality :

Subtract 13 from both sides to get t≤−13

Tim Hanes' bank granted him a single payment loan of $1,000 for 100 days at 12 percent ordinary interest. What is the maturity v

mash [69]

Answer:

$1032.87

Step-by-step explanation:

First we need to calculate the interest

Interest = Principal * rate * time/100

Interest = 1000 * 12 * 100/365 * 100

Interest = 12000/365

Interest = 32.87

maturity value = Principal + Interest

maturity value = 1000 + 32.87

maturity value = $1032.87

Answer:

$\sf C. \quad \dfrac{1}{9}$

Step-by-step explanation:

<u>Addition Law for Probability</u>

$\sf P(A \cup B)=P(A)+P(B)-P(A \cap B)$

Given:

$\sf P(A)=\dfrac{1}{3}=\dfrac{3}{9}$

$\sf P(B)=\dfrac{2}{9}$

$\sf P(A \cup B)=\dfrac{4}{9}$

Substitute the given values into the formula and solve for P(A ∩ B):

$\implies \sf P(A \cup B) = P(A)+P(B)-P(A \cap B)$

$\implies \sf \dfrac{4}{9} = \sf \dfrac{3}{9}+\dfrac{2}{9}-P(A \cap B)$

$\implies \sf P(A \cap B) = \sf \dfrac{3}{9}+\dfrac{2}{9}-\dfrac{4}{9}$

$\implies \sf P(A \cap B) = \sf \dfrac{3+2-4}{9}$

$\implies \sf P(A \cap B) = \sf \dfrac{1}{9}$

Solve for all values of x in simplest form. 9-4|3+5x|=5

Zinaida [17]

Answer:

$x=-2/5\text{ or } x=-4/5$

Step-by-step explanation:

So we have the equation:

$9-4|3+5x|=5$

First, subtract 9 from both sides:

$-4|3+5x|=-4$

Divide both sides by -4:

$|3+5x|=1$

Definition of Absolute Value:

$3+5x=1\text{ or } 3+5x=-1$

Subtract 3 from both sides:

$5x=-2\text{ or } 5x=-4$

Divide both sides by 5:

$x=-2/5\text{ or } x=-4/5$

And we're done!
