Answer:
x<-6
Step-by-step explanation:
You subtract 4 from both sides. Then, since the x is negative you have to divide it by a negative 1 on both sides so it turns into a positive. Since you divided by a negative, the inequality symbol flips.
Answer:
Step-by-step explanation:
f(x)=2x²+4x-1
=2(x²+2x+1-1)-1
=2(x²+2x+1)-2-1
=2(x+1)²-3
domain: all real values
Range:[-3,∞)
The sum of any two rational numbers is rational. Both of these numbers are rational, therefore adding them will give us another rational number.
Google it that’s what I will don
With finding the data that falls below a percentage, you need to look closely at the words.
Notice that it said 25% of... that word "of" means to multiply. But, what are you multiplying? Well, if you look more closely at the plot, you'll see that your dot and line is lying on 58. But make sure you put 25 over 100.
So, your equation would be set up like this: 58 ÷ x = 100/25
We're using "x" as our way of saying, "We need to find out this number."
After that, we'll need to multiply both sides of the equation by "x"
(58 ÷ x) × x = (100/25) × x
Now that you have your equation, you'll need to divide both sides by 4 to get "x".
x = 4 ÷ 58
58 ÷ 4 = 14.5
Your answer is 14.5 of the data that falls below the number.
