7.75+1.25x= 32.75
32.75-7.75=25
1.25x= 25
25 divided by 1.25
X= 20

Reptile [31]

Answer:

$\frac{14}{15}$

Step-by-step explanation:

$\frac{4}{5}$ × $\frac{3}{9}$ + $\frac{2}{3}$ ( firstly, multiply the 2 fractions together )

= $\frac{12}{45}$ + $\frac{2}{3}$

= $\frac{4}{15}$ + $\frac{2}{3}$

= $\frac{4}{15}$ + $\frac{2(5)}{3(5)}$

= $\frac{4}{15}$ + $\frac{10}{15}$

= $\frac{14}{15}$

Evaluate the indicated limit algebraically. Change the form of the function where necessary. Please write clearly with descripti

alukav5142 [94]

Answer:

$\displaystyle \lim_{x\to \infty}\frac{3x^2+4.5}{x^2-1.5}=3$

Step-by-step explanation:

We want to evaluate the limit:

$\displaystyle \lim_{x\to \infty}\frac{3x^2+4.5}{x^2-1.5}$

To do so, we can divide everything by <em>x</em>². So:

$=\displaystyle \lim_{x\to \infty}\frac{3+4.5/x^2}{1-1.5/x^2}$

Now, we can apply direct substitution:

$\Rightarrow \displaystyle \frac{3+4.5/(\infty)^2}{1-1.5/(\infty)^2}$

Any constant value over infinity tends towards 0. Therefore:

$\displaystyle =\frac{3+0}{1+0}=\frac{3}{1}=3$

Hence:

$\displaystyle \lim_{x\to \infty}\frac{3x^2+4.5}{x^2-1.5}=3$

Alternatively, we can simply consider the biggest term of the numerator and the denominator. The term with the strongest influence in the numerator is 3<em>x</em>²<em>, </em>and in the denominator it is <em>x</em>². So:

$\displaystyle \Rightarrow \lim_{x\to\infty}\frac{3x^2}{x^2}$

Simplify:

$\displaystyle =\lim_{x\to\infty}3=3$

The limit of a constant is simply the constant.

We acquire the same answer.
