Solve and graph: 7x-6&gt;22<br>(pls explain your answer, im confused on this)​
grandymaker [24]

Answer:

x>4

Step-by-step explanation:

Solving an inequality is very similar to solving an equation:

Given: 7x-6>22

Add 6 to both sides: 7x>28

Divide both side by 7: x>4

x>4 means that all x-values that are greater than 4 will work. Therefore you would write an open dot at x=4 on the number line to show that 4 isn't included, and draw an arrow going right to show all possible solutions greater than 4.

Solve for x:negative 4 over 3, multiplied by x minus 6 equals negative 26 a−27 b−15 c15 d27
rosijanka [135]

Answer:

C

Step-by-step explanation:

-4/3 x - 6 = -26

Add 6 to both sides

-4/3 x = -20

Divide both sides by -4/3, which is the same as multiplying by reciprocal

-20 * -3/4 = 15

x = 15
