The answer is D
9x²+6x+1=
=(3x+1)²=
=(3x+1)(3x+1)
The y-intercept is 665, because of the ordered pair shown in the table, (0,665).
The rate of change is found by the formula of y2-y1/x2-x1.
So, (285-665)/(4-0)
-380/4
-95
Therefore, the rate of change in the table is (-95).
It represents the distance traveled (y) for every hour passed (x).
The equation for this table is
-95x+665.
If we were to continue the table, we would find that once 7 hours passes, the distance reached 0.
Therefore, a reasonable domain for this table is “x is equal to or more than 0, and x is equal to or less than 7”
A:665
B:-95
C:x is equal to or more than 0, and x is equal to or less than 7
As it is reduced by 10%, £810 is 90% of the original cost.
So you do (810 / 90) x 100 = £900
Answer:
x > 3

Step-by-step explanation:
<u>Step 1: Define</u>
<em>Identify</em>
8x - 6 > 12 + 2x
<u>Step 2: Solve for </u><em><u>x</u></em>
- [Subtraction Property of Equality] Subtract 2x on both sides: 6x - 6 > 12
- [Addition Property of Equality] Add 6 on both sides: 6x > 18
- [Division Property of Equality] Divide 6 on both sides: x > 3
