[35/(25-54)]-{225/{(56-5)(729/81)}=

1 answer:

6 0

Consider the expressions separately:

$\frac{35}{25-5*4}= \frac{35}{25-20}=\frac{35}{5}=7$

$\frac{225}{( 5*6-5 )( \frac{729}{81} )}= \frac{225}{( 30-5 )( 9 )}= \frac{225}{( 25 )( 9 )}= \frac{9}{9}=1$

So: $\frac{35}{25-5*4}-\frac{225}{( 5*6-5 )( \frac{729}{81} )}=1-7=-6$

If I multiply a number L by another number M, I get 452,199. If I multiply L by the successor of M, I get 454,322. Find L x L.

Genrish500 [490]

Step-by-step explanation:

L * M = 452,199

L * (M + 1) = 454,322

Therefore L * (M + 1) = L * M + L.

=> 454,322 = 452,199 + L, L = 2,123.

Hence L² = 2,123² = 4,507,129.

Identify the values of m and b of the linear function y = mx + b, graphed below.

<h2>Finding the slope and y-intercept of a line given the graph</h2><h3>Answer:</h3>

$b = 4$

$m = -\frac{1}{3}$

<h3>Step-by-step explanation:</h3>

An equation of a line written in its Slope-intercept Form, $y = mx +b$ , has $b$ as its $y$ -intercept and $m$ as its slope.

$b$ or the $y$ -intercept is the $y$ -coordinate when $x = 0$ . On the given line, we can see that when $x = 0$ , $y = 4$ . It's $y$ -intercept is the point $(0,4)$ so $b = 4$ .

The slope, $m$ , of the line can be calculated by $\frac{y_2 -y_1}{x_2 -x_1}\\$ where $x_n$ and $y_n$ is the $xy$ -coordinates of any point $n$ on the line. In the given line, we can see that $(5,3)$ is on the line so this can be point $1$ . $(0,4)$ is also on the line (yes, you can also use the $y$ -intercept in calculating the slope of the line) so this can be our point $2$ .
