Answer:

One denominator you could use to add the two fractions 3/1 and 8/12 is 12.

Step-by-step explanation:

When adding the fractions 3/1 and 8/12, the first step is to multiply both the numerator and denominator by the same number until you end up with common denominators. Here, the best thing to do is multiply both 3 and 1 by 12 which ends in 36/12; from that point on, you just do the simple math of 36/12 + 8/12.

Step-by-step explanation:

The quotient of the given fractions is 6.

The division is one of the basic arithmetic operations in math in which a larger number is broken down into smaller groups having the same number of items.

Given that, 9/4 divided by 3/8.

When two fractions are divided, the first fraction is multiplied by the second fraction's reciprocal. Finding the reciprocal of the second fraction reversing its numerator and denominator is the first step in dividing fractions. Multiply the two numerators after that. Multiply the two denominators after that.

Here, 9/4 ÷ 3/8

= 9/4 × 8/3

= 3 × 2

= 6

Therefore, the quotient is 6.

Answer:

3d+15

Step-by-step explanation:

You would have to do distributive property. 3*d+3*5=3d+15

Step-by-step explanation:

first find the derivative and then substitute x=1

d/dx((x^2 -2)/(x^2 + 1)) = (2*x)/(1+x^2)+(4*x)/(1+(2*x^2)+x^4)+(-2*x^3)/(1+(2*x^2)+x^4)

substitute x=1

check the image above

slope = 1.5

The slope of the line tangent when x = 1 is 1.5.

An equation is a mathematical statement that is made up of two expressions connected by an equal sign.

Example:

2x + 4  = 9 is an equation.

We have,

y = (x² - 2)/(x² + 1)

y' = [(x² + 1)(2x) - (x² - 2)(2x)] / (x² + 1)²

Put x = 1

dy/dx = [(1² + 1)(2) - (1² - 2)(2)] / (1² + 1)²

dy/dx = (4 + 2)/4

dy/dx = 6/4 = 3/2 = 1.5

Thus,

The slope is 1.5.
