Integers are any whole number(not fraction) that can be possitive or negative however she can not buy a negative amount of tickets so that is not the answer
whole numbers are any not fraction number that is positive this is a possible answer
rational numbers are any number that is terminates if it is a decimal or is a repeating decimal this does not include decimals like pi that don't end and dont repeat this cant be the answer
a real number is any number rational or irrational this also cant be the answer
the answer is B
i hope i made sense
Answer: Y = -10
Step-by-step explanation:
-x + y = -27
-17 + y = -27
+17 +17
Y = -10
You can also check your work by plugging in the X and Y values and it should equal -27 . So -17 + -10 equals -27.
Answer:
x = - 4 , x = 
Step-by-step explanation:
given 2x² + 7x = 4
rearrange into standard form : ax² + bx + c = 0 : a ≠ 0
subtract 4 from both sides
2x² + 7x - 4 = 0 ← in standard form
Consider the product of the factors of the coefficient of the x² term and the constant term which sum to give the coefficient of the x term, that is
product = 2 × - 4 = - 8 and sum = + 7
The factors are + 8 and - 1
use these factors to split the middle term
2x² + 8x - x - 4 = 0 ( factor by grouping first/second and third/fourth terms )
2x(x + 4) - 1(x + 4) = 0 ( take out the common factor (x + 4) )
(x + 4)(2x - 1) = 0
equate each factor to zero and solve for x
x + 4 = 0 ⇒ x = - 4
2x - 1 = 0 ⇒ 2x = 1 ⇒ x =
Answer:
the answer to the inequality is C. g<1
Limit definition of Derivative of a function at x=a : :
lim (f(a+h)-f(a))/h =
h->0
From limit definition i need just h in the denominator, so i can substitute, h = x-pi/4 as
x -> pi/4, h ->0
also x = pi/4+h
Comparing this with limit definition f(a+h) and tan (pi/4+h), we can figure out , f(x) = tan x , and a = pi/4. I hope that this is the answer that you were looking for and it has helped you.
