Solve for x. x+15.09=−2.57 enter your answer as a decimal in the box. solve for x. −6> −30−4x enter your answer, as an inequality, in the box. solve for t. −22t> 66 enter your answer, as an inequality, in the box.

Answers:

1)In this first question we have to clear from the following equation:

2)Here we have to find the value of in the following inequality:

Then:

3)Here we have to find the value of in the inequality:

Note that -22 is a negative number and is dividing , this number goes to the other side of inequality dividing, and the direction of the inequality must change:

Finally:

5=812a+9+3

step 1: simplify both sides of the equation.

5=812a+9+3

5=(812a)+(9+3)(combine like terms)

5=812a+12

5=812a+12

step 2: flip the equation.

812a+12=5

step 3: subtract 12 from both sides.

812a+12−12=5−12

812a=−7

step 4: divide both sides by 812.

812a /812 = -7/812

a= -1/116

so the answer is

a=   -1/116

- both graphs increase on their domain.

- the graphs of both functions have the same x-intercept.

- neither graph has a y-intercept.
