5x-6><span>9
--------------------
Add 6 on each side of the equation
</span><span><span>5x-6</span>+6</span>><span>9+6
</span><span>5x</span>><span>15
</span>--------------------------
Divide each side by 5
5x ÷ 5 > 15 ÷ 5
x > 3
-------------------------------------
x > 3 is your answer
Answer:
1 13/30
Step-by-step explanation:
First you want to make the denominators the same. You do this by multiplying them. However, whatever you do you to the denominator, you must also do to the numerator:
-
=
-
=
Now reduce to simplest terms:
=1
Answer:
(4b-9) (4b+9)
Step-by-step explanation:
16b^2 – 81
This is the difference of squares
(a^2 -c^2) = (a-c) (a+c)
a^2 = 16b^2 so a= 4b
c^2 = 81 so c = 9
(16b^2 – 81) = (4b-9) (4b+9)
Answer:
D. y= 0.3x2
Step-by-step explanation:
In quadratic functions, the value of a affects the wideness of the graph. The smaller the absolute value of a, the wider the graph. In these choices, 1/3 and 0.3 are the smallest. To understand which is smaller convert both to decimals; 1/3 is 0.3333 repeating. Therefore, 0.3 is slightly smaller and wider.
