Answer:
[5, 0]
Step-by-step explanation:
x-intercept is where <em>0</em><em> </em><em>=</em><em> </em><em>y</em><em>.</em><em> </em>Just simply plug in 0 for <em>y</em><em>,</em><em> </em>then your <em>x</em><em> </em>is given to you in your face.
If I can write your number as a fraction with whole numbers
on top and bottom, then your number is rational.
1.313233 = 1,313,233 / 1,000,000 yay !
I did it ! Your number is rational.
Here's a hint that will give you the rational/irrational answer
to probably 95% of the examples you ever see:
Any number that you can write down on paper, completely,
using digits (and a decimal point or fraction bar if necessary)
is always rational.
Answer:
24 : 13 or 24/13
Step-by-step explanation:
96/4 = 24
52/4 = 13
Answer:
-4e - 9
Step-by-step explanation:
This requires combining like terms, which means that you combine the same types of values. In this one there are two "types" of values: something that involves the variable e and just normal numbers. Let's say that the "e"s are oranges and the regular numbers are apples. Remember, you can't simply add oranges and apples together
let's start with apples (the regular numbers)
you have -19 (just pretend the minus sign is attached to the value following)
and +10
so -19+10 is -9
we have -9 apples
so now let's look at oranges, represented by e
you have 3e and -7e
if one e is one orange, then you could say that there are 3 oranges and -7 oranges
so if you subtract you get -4e, or -4 oranges
now let's add that back together with the apples, remembering that you can't actually combine them
so it would be -4e - 9
(-4 oranges and -9 apples)
U=2x+3, x=u/2-3/2
u^2+8u+11=0
u1=(-8+sqrt(64-44))/2=-4+sqrt(5)
u2=-4-sqrt(5)
x1=u1/2-3/2=-7/2+sqrt(5)/2
x2=u2-3/2=-7/2-sqrt(5)/2
