Answer:

5% increase

Step-by-step explanation:

let's say your unit percent was 100, you had a 9 percent decrease thats 91 percent now you get a 14 percent increase which leaves you with 105 percent. compared to your original percent you got a 5 percent increase!

−6x + 14 < −28 OR 9x + 15 ≤ −12. solve for x.
sasho [114]

Answer:

x>7 or x ≤ -3

Step-by-step explanation:

Solving the 1st inequality

-6x +14 < -28 --------------- (Collect like terms)

-6x < -28 - 14

-6x < - 42 -------------------- (Divide both sides by -6)

Note: If you decide an inequality expression by a negative value, the inequality sign changes)

-6x/-6 > -42/-6

x > 7

Solving the 2nd inequality

9x + 15 ≤ −12 ----------- (Collect like terms)

9x ≤ −12 - 15

9x ≤ −27 ------------------(Divide both sides by 9)

9

9x/9 ≤ −27/9

x ≤ -3

Bring both results together, we get

x>7 or x ≤ -3

The final result is complex (i.e. can't be combined together).

Please help me out with this!!!!!
Scrat [10]

The exercise is basically asking: how much do we have to add to x to get y?

If you look at the table, the y value is always 4 more than the correspondent x value.

So, in order to get y, you must add 4 to x.

y=x+4
