Zielflug [23.3K]

Answer:

(-1, -5) satisfies the inequality and will be the solution to the inequality.

From the attached figure, it is clear that  (-1, -5) is below the line.

Therefore, the correct option is:

''Yes, because 1-1, 5) is on the line​''.

Step-by-step explanation:

Given the inequality

y\le -\frac{3}{4}x-1

substituting (-1, -5)  to check whether it satisfies the inequality or not

-5\le \:-\frac{3}{4}\left(-1\right)-1

-5\:\le \:\frac{3}{4}-1

-5\:\le -\frac{1}{4}

TRUE

Thus, (-1, -5) satisfies the inequality and will be the solution to the inequality.

From the attached figure, it is clear that  (-1, -5) is below the line.

Therefore, the correct option is:

''Yes, because 1-1, 5) is on the line​''.

the price of the cell phone is expected to increase by 165% in September 2015. The current price of a cell phone is $62.80. What
Sladkaya [172]

Answer:

$166.42.

Step-by-step explanation:

We have been given that the price of the cell phone is expected to increase by 165% in September 2015. The current price of a cell phone is $62.80.

The price of cell phone in September 2015 will be $62.80 plus 165% of $62.80.

\text{The predicted cost of a cell phone in September 2015}=\$62.80+(\frac{165}{100}*\$62.80)

\text{The predicted cost of a cell phone in September 2015}=\$62.80+(1.65*\$62.80)

\text{The predicted cost of a cell phone in September 2015}=\$62.80+\$103.62

\text{The predicted cost of a cell phone in September 2015}=\$166.42

Therefore, the predicted cost of a cell phone in September 2015 will be $166.42.

X^2 + 6x - 18 solve for x​
Simora [160]

Answer:

x = - 3  ± √27 or if you want it in decimal form correct to  nearest hundredth:

x = -8.20, 2.20.

Step-by-step explanation:

x^2 + 6x - 18 = 0

this will not factor so we use completing the square:

x^2 + 6x = (x + 3)^2 - 9 so:

(x + 3)^2 - 9 - 18 = 0

(x + 3)^2 = 27

x+ 3 = ±√27

x = - 3  ± √27
