Divide the fractions and simplify the answer . 1/2 ÷ 5/8

1 answer:

3 0

Dividing fractions is equivalent to taking the reciprocal of the second and multiplying them. In this case, we have 1/2*8/5=8/10=4/5.

Why are the southern slopes of mountains warmer than northern slopes?

lilavasa [31]

In the northern hemisphere a south-facing slope (more open to sunlight and warm winds) will generally be warmer and drier due to higher levels of evaporation and transpiration than a north-facing slope. So South facing slopes are much warmer.

1. Solve the system by substitution.

zubka84 [21]

Answer:

The required solution is (0.128,13.82)

Step-by-step explanation:

Consider the provided system of equation.

$-2.5x+y=13.5$ ......(1)

$12.25x - y=-12.25$ ......(2)

We need to solve the system of equation by substitution method.

Consider the equation 1.

$-2.5x+y=13.5$

$y=13.5+2.5x$ ......(3)

Substitute the value of y in equation 2.

$12.25x - (13.5+2.5x)=-12.25$

$12.25x-13.5-2.5x=-12.25$

$9.75x-13.5=-12.25$

$9.75x=-12.25+13.5$

$9.75x=1.25$

$x\approx 0.128$

Now substitute the value of x in equation 3.

$y=13.5+2.5(0.128)$

$y\approx 13.82$

Hence, the required solution is (0.128, 13.82)

F(x)=12x2-4x-8. G(x)=11x-6

AlekseyPX

Answer: Second option.

Step-by-step explanation:

Given the functions f(x) and g(x):

$f(x)=12x^2-4x-8\\\\g(x)=11x-6$

You need to divide them in order to find $(\frac{f}{g})(x)$ asked in the exercise. Then:

$(\frac{f}{g})(x) =\frac{12x^2-4x-8}{11x-6}$

Now, it is important to remember that, by definition, the division by zero is not defined. Therefore, the denominator of the function cannot be zero.

Let's find the value of "x" for which the denominator of the function would be zero:

1. You need to make the denominator equal to zero:

$11x-6=0$

2. Finally, you must solve for "x":

$11x=6\\\\x=\frac{6}{11}$

Therefore, as you can see, the answer is:

$(\frac{f}{g})(x) =\frac{12x^2-4x-8}{11x-6}$ , $x=\frac{6}{11}$
