Answer:
k = 48
For x = 6, y = 8.
Step-by-step explanation:
The general equation for inverse variation is
y = k/x
We are told that y = 24 when x = 2, so we plug in those two values in the general equation to find the value of k.
24 = k/2
k = 24 * 2 = 48
Now that we know k = 48, the equation for our case is
y = 48/x
Now we plug in x = 6 and find y.
y = 48/x
y = 48/6
y = 8
Which is more 4/5 or 0.71? Because decimals are usually easier to read, convert the 4/5 to a decimal. To do this, divide the numerator by the denominator. 4 / 5 = 0.8.
0.8 is bigger than 0.71. So, 4/5 is definitely bigger than 0.71.
But what about 1.2 and 1 2/9? Again convert 1 2/9 to a decimal.
2/9 = 1.222...
And 1.222 repeating is bigger than 1.2
Answer:
4×(x² - 4x + 2)
Step-by-step explanation:
4x2 - 16x + 8 = 4×x² - 4×4×x + 4×2 = 4×(x² - 4×x + 2)
