Answer:
The solutions are -0.65 and 4.65.
Step-by-step explanation:
3x^2 - 12x = 9
Divide both sides by 3
x^2 - 4x = 3
To make a square with "x^2 - 4x", you need to have a "+ 4" after it so it can be simplified as (x-2)^2. So add 4 to both sides.
x^2 - 4x + 4 = 7
(x-2)^2 = 7
x - 2 = (square root) of 7
x = 2 (+/-) (square root) of 7.
x = {-0.65, 4.65}
The solutions are -0.65 and 4.65.
hope this helps:)sorry if it doesnt
The equations to represent the relationship are ƒx3/5=4 4/5 and 4 4/5 divided 3/5 =f
<h3>Ratio and proportion</h3>
Fractions are written as a ratio of two integers. For instance a/b is a fraction.
If Anastacio distributed 4 4/5 kg of seed among several bird feeders and put 3/5 kg of seed in each feeder, the expression that represents the number of bird feeders that Anastacio filled is given as;
Number of bird feeder = 4 4/5 ÷ 3/5
f = 4 4/5 ÷ 3/5
Multiply both sides by
f * 3/5 = 4 4/5 ÷ 3/5 * 3/5
f * 3/5 = 4 4/5
Hence the equations to represent the relationship are ƒx3/5=4 4/5 and 4 4/5 divided 3/5 =f
