Ok soo

First substitute the value for x Ok x=23/7 + 3/7 y. 2x-4y=-8

Second solve the equation 2(23/7 +3/7 y) -4=-8

Third substitute the value of y do y=51/11

Forth solve the equation X=23/7 +3/7 x 51/11

Fifths the possible solution is x=58/11

Sixth check the solution (x,y)=(58/11, 51,11)

Seventh simplify 7x58/11-3x51/11=23. 2x58/11-4x51/11=-8

The ordered pair is a solution 23=23. -8=-8

(x,y)=(58/11, 51,11)

$Q. 7x - 3y =23$

$Lets, \: Find \: x :-$

$7x - 3y = 23$

$7x - 3(0) = 23$

$x = 3.286$

$Now, Lets \: find \: y :-$

$7x - 3y = 23$

$7(0) - 3y = 23$

$y \: = -7.667$

The sum of three consecutive odd numbers is less than or equal to 33. Write an inequality and solve to determine the maximum val

Dmitry [639]

Answer:

9

Step-by-step explanation:

If first odd number is x

THen next consecutive odd number is x + 2

Next one is x + 4

Now, we can write the word problem as:

$x+x+2+x+4 \leq 33$

Now we solve:

$x+x+2+x+4 \leq 33\\3x+6 \leq 33\\3x \leq 27\\x \leq 9$

So, x is less than or equal to 9, so it can be

9, 7, 5 .....

What is the maximum value of the lowest number (x)?? It is 9

Your graph should look something like the one below, an exponential function (this is because your are raising a number to the power of x.
