Which ordered pairs make the inequality true?

1 answer:

7 0

1.
$(-2,3) \\
x=-2 \\
y=3 \\ \Downarrow \\
-2+3 \times 3$

The ordered pairs (-2,3) and (5,1) make the inequality true.

2.
$15y-3(4y+10)=15y-3 \times 4y-3 \times 10= 15y-12y-30= \\
=3y-30$

The simplified form of the expression is 3y-30.

A scientist writes the equation n(h)100e^0.25h to model the growth of a certain bacteria in a petri dish, where N represents the

Natasha2012 [34]

Answer: Second option is correct.

Step-by-step explanation:

Since we have given that

$n(h)=100e^{0.25h}$

where, N represents the number of bacteria after 'h' hours.

So, we have given that there are 450 bacteria present.

N = 450

According to question,

$450=100e^{0.25h}\\\\\frac{450}{100}=e^{0.25h}\\\\4.5=e^{0.25h}\\\\\text{Taking natural log 'ln' on both sides}\\\\\ln (4.5)=0.25h\\\\1.50=0.25h\\\\h=\frac{1.50}{0.25}\\\\h\approx 6\ hours$

Hence, Second option is correct.
