Okay first
22x+11=5x-7
You need to move the variables so it eaquals 0
22x+11-5x+7=0
Now combine like terms
17x+18=0
Move 18 over to divide
17x=-18
X= -1.1 or just -1
Good luck! :D
Im sorry, I cant see what it is you want me to do??
Answer:
a) two
b) S = {Orange, Purple}
c) 50%
d) 50%
Step-by-step explanation:
a)
When a marble is drawn from the jar, there are <u>two</u> possible outcomes. Either the marble will be orange or it will be purple.
b)
A sample space is a set of all possible outcomes of an event. Thus, the sample space in this case will be:
<u>Sample Space = {Orange, Purple}</u>
c)
The probability of an event is given as the number of favorable outcomes divided by the number of total outcomes.
Therefore,
Probability of selecting orange marble = P(Orange) = 1/2
<u>P(Orange) = 0.5 = 50%</u>
d)
Probability of selecting purple marble = P(Orange) = 1/2
<u>P(purple) = 0.5 = 50%</u>
X^2+x=2
first set to zero
x^2+x=2
subtract 2 from both sides
x^2+x-2=0
factor because if you have
x times y=0 then assume x and/or y=0 so
factor x^2+1x-2
to factor you find what 2 number add to 1 and multiply to get -2
the numbers are -1 and 2 so
it factors out to
(x-1)(x+2)=0
assume each is zero
x-1=0
add 1 to both sides
x=1
x+2=0
subtract 2 from both sides
x=-2
x=1 or -2
the first picture number 1 is a function
the second one the third one
but I'm not sure
