Help please Order the numbers from smallest to largest: 10 , 23 , |-9|, and 1.2 × 101

0.03x+20=0.07x+5 original equation
0.03x+20-0.03x=0.07x+5-0.03x subtract 0.03x from both sides to combine like terms
20=0.04x+5
20-5=0.04x+5-5 subtract 5 from both sides
15 = 0.04x
15/0.04 = 0.04x/0.04 divide both sies by 0.04 to get x alone.
375 = x <-------WOOOOOO! theres the answer!

Which table shows a function that is decreasing only over the interval (–1, ∞)?

aleksandr82 [10.1K]

The table that shows a function that is decreasing only over the interval (–1, ∞) is:

A 2-column table with 6 rows. The first column is labeled x with entries negative 3, negative 2, negative 1, 0, 1, 2. The second column is labeled f of x with entries negative 1, negative 3, negative 5, negative 2, negative 1, 2.

<h3>When a function is decreasing?</h3>

A function is decreasing if when we increase the value of x, we decrease the value of y, and vice versa.

Decreasing on the (–1, ∞) means that as x increases on the interval, i.e. x = -100, then x = -10, then x = -2, the value of y decreases. The function that follows this pattern only on this interval is:

A 2-column table with 6 rows. The first column is labeled x with entries negative 3, negative 2, negative 1, 0, 1, 2. The second column is labeled f of x with entries negative 1, negative 3, negative 5, negative 2, negative 1, 2.

Is (2, 3) a solution to this system of equations? 2x + 5y = 19 X + 16y = 5 yes no

chubhunter [2.5K]

Answer:

No

Step-by-step explanation:

To check if (2,3) is a solution to the system of equations, we simply have to plug the coordinate points into the two equations and see if it is valid.

$2*2+5*3=\\4+15=\\19\\\\19=19$

(2,3) belongs in the first equation.

$2+16*3=\\2+48=\\50\\\\50\neq 5$

(2,3) does not belong in the second equation.

Therefore, (2,3) is not a solution to this system of equations.

I hope this helps! Let me know if you have any questions :)
