The graph below shows the solution to which system of inequalities?
nlexa [21]

Answer:

Option D.

Step-by-step explanation:

Consider option D. y\leq \frac{3x}{4}+10\,,\,y\leq \frac{-x}{2}-3

Take point (0,0)

On putting this point in inequation y\leq \frac{3x}{4}+10 , we get

0\leq 10 which is true . So, solution is region towards the origin i,e region below the line y= \frac{3x}{4}+10 including the line itself .

On putting (0,0) in inequation y\leq \frac{-x}{2}-3 , we get 0\leq -3 which is false , so solution is region away from the origin i.e region below line y= \frac{-x}{2}-3 including the line itself .

So, common solution to both the inequations is the shaded part in the given figure .

In other words, we can say that the graph shown in the given figure represents system of equations: y\leq \frac{3x}{4}+10\,,\,y\leq \frac{-x}{2}-3

Mike's monthly pay after taxes is $2,300.
wlad13 [49]

Step-by-step explanation:

100%=>$2,300

45%=>x

x=$2,300×45÷100=$1035

The pay left for other purposes

$2300-$1035=$1265

Or:

100%=>$2,300

55%=>x

x=$2,300×55÷100=$1265.

Type the correct answer in each box. Use numerals instead of words.
Hatshy [7]

Answer:

(4,-3) and (-2,5)

Step-by-step explanation:


It was given that the points (-3,4) and (5,-2) are on the graph of the function f.


If g is the inverse function of f, then g will take the y-values as inputs and give the x-values as outputs.

Hence we will have the ordered pairs (4,-3) and (-2,5)

on g.


In other words, f and g are symmetric about the line y=x. This implies that when we reflect the points (-3,4) and (5,-2) in the line y=x we will obtain (4,-3) and (-2,5).


This point must lie on g.
