Answer:
12rf
Step-by-step explanation:
4 times 3 is 12 and r times f just becomes rf so you are correct.
Step-by-step explanation:
Hey there!
Given eqautions are:
y = 2x + 1......... (i)
y = 4x - 3...........(ii)
<em>Putting eqaution (ii) in eqaution (i), we get;</em>
4x - 3 = 2x + 1
<em>~ Keep like terms on same side.</em>
4x - 2x = 1+3
<em>~ Perform operations. ( +, -, *, /)</em>
2x = 4
x= 4/2
Therefore, X= 2.
<em>Putting the value of X in eqaution (i)</em>
y = 2x+1
y = 2*2+1
Therefore, y= 5.
Therefore, the ordered pair is (2,5).

Answer:
The probability is 0.05 or 5%
Step-by-step explanation:
Of 6 cars the probability of 3 being a lemon is:
[tex]frac{{3!3!}{6!}} [\tex]
Picking the first one a lemon is [tex]frac{{3}{6}} [\tex] , the second one also lemon [tex]frac{{2}{5}} [\tex] and the third one [tex]frac{{1}{4}} [\tex].
[tex]frac{{3*2*1}{6*5*4}} [\tex] can be rearanged as
[tex]frac{{3!3!}{6!}} [\tex]
