Which graph shows the solution to the inequality -3x-7x<20

hjlf

A graph of this inequality would be a number line, with the number -2 circled (not filled in), and the number line to the right of -2 shaded.

To solve this, you will combine like terms first:

-3x-7x < 20
-10x < 20

Divide both sides by -10:
-10x/-10 < 20/-10

When you divide an inequality by a negative number, you flip the inequality symbol:

x > -2

The price of a specic model of a new car decreased from $23,000 to $21,000 in one year. What is the

Alex

The decrease is 8.7%

Step-by-step explanation:

Old price = $23000

New price = $21000

Difference = New price - Old price

Difference = 21000 - 23000 = -2000

The negative sign indicates the decrease.

$Percent\ decrease=\frac{Difference}{New\ value}*100\\\\Percent\ decrease=\frac{2000}{23000}*100\\\\Percent\ decrease=\frac{200000}{23000}\\\\Percent\ decrease=8.69\%$

Rounding off to nearest tenth;

Percent decrease = 8.7%

The decrease is 8.7%
