Which of the following expressions is the inverse of the function y equals quantity x minus 2 divided by 3?

Natalija [7]

Y = (x - 2)/3
3y = x - 2
x = 3y + 2

Solve using the quadratic formula 3x^2+11x+5=0

storchak [24]

Answer:

$3x^2 + 11x + 5 = 0 : x = \frac{-11 + \sqrt{61} }{6} , x = \frac{-11 - \sqrt{61} }{6}$

Decimal:

$(x = -0.53162..., x = -3.13504...)$

Step-by-step explanation:

$3x^2+11x+5=0$

Solve with the quadratic formula:

For a quadratic equation of the form $ax^2+bx+c=0$ the solutions are:

$x_{1,\:2}=\frac{-b\pm \sqrt{b^2-4ac}}{2a}$

For $a=3,\:b=11,\:c=5:\quad x_{1,\:2}=\frac{-11\pm \sqrt{11^2-4\cdot \:3\cdot \:5}}{2\cdot \:3}$

$x=\frac{-11 + \sqrt{11^2-4\cdot \:3\cdot \:5}}{2\cdot \:3} : \frac{-11 + \sqrt{61} }{6}$

$x=\frac{-11 - \sqrt{11^2-4\cdot \:3\cdot \:5}}{2\cdot \:3} : \frac{-11 - \sqrt{61} }{6}$

The solutions to the quadratic equation are:

$x=\frac{-11+\sqrt{61}}{6},\:x=\frac{-11-\sqrt{61}}{6}$

Hope I helped. If so, may I get brainliest and a thanks?

Thank you, have a good day! =)

An ounce is equal to about 28 g. If 1 g of soil contains 2.5 billion bacteria, how many bacteria are in 1 oz of soil?

Nimfa-mama [501]

Answer:

About 700 billion bacteria

Step-by-step explanation:

Given

$1oz \approx 28g$

$1g = 25\ billion\ bacteria$

Required

Number of bacteria in 1 oz

$1g = 25\ billion\ bacteria$

Multiply both sides by 28

$28 * 1g = 25\ billion\ bacteria * 28$

$28g = 700\ billion\ bacteria$

Recall that

$1oz \approx 28g$

This means:

$1oz \approx 700\ billion\ bacteria$
