Answer:
Step-by-step explanation:
Two negative signs equate to a positive sign, so we can write as just :
Add up similar terms:
Add 21 to both sides:
Subtract x from both sides:
Divide both sides by 4:
Answer:
(1,4)
Step-by-step explanation:
The two lines intersect at 1,4 when you graph them
The first equation is already in slope intercept from, so you know the y-int. is 7 and the slope is 3. However, the second equation must be put in slope int. form.
5x+2y=3
move the y to the other side
5x=3-2y
move the 3 to the other side, so the y variable is by itself
5x-3=-2y
divide by -2 to the equation is equal to y
(-5x/2)+(3/2)=y
you now know the y int. of the second equation is 3/2 and the slope is -5/2
know that you know the slop int. formulas for both equations you can graph them
The sets containing π have that as an irrational element. The other numbers in the set are rational, so NO SET contains Only Irrational Numbers.
_____
Sets A and D appear to contain Only Rational Numbers.
Answer:
987.
Step-by-step explanation:
The terms in a Fibonacci series are obtained form the sum of the previous 2 terms. So the next number F(16) = 377 + 610 = 987.
