168 students because 28% of 600 is 168.
Step-by-step explanation:
the domain is the set or range of valid values for x.
the range is the set or range of valid values for y (= f(x)).
if you did not miss anything in your problem statement, then I see a function
y = 2x - 11 + 2
no restrictions are defined.
so, domain and range are both the interval
(-infinity, +infinity).
notice the round brackets, as "infinity" is never a value and cannot be included in an interval.
now, if you missed a division sign and the function looks like
y = 2/x - 11 + 2
then we know, x must never be 0, as a division by 0 is undefined.
so, the domain in that case would be
-infinity < x < 0, 0 < x < +infinity
or short
x <> 0
the range would still be every possible value in
(-infinity, +infinity).
The answer is 3.3. and represents a decimal and tenths is the place value right after the decimal
The vertex is (26,14)
Because it’s written in vertex form which y=a(x-h)^2 + k. H is the x for the vertex And h is changed to it’s opposite. So since 26 is negative it would actually be positive 26. While k ls the y of the vertex which is 14 in our case
Answer
Evaluate the expression
4ab + 5bc
when a = 2, b = –6, and c = –2.
To prove
As the expression given in the question be
4ab + 5bc
As given
a = 2, b = –6, and c = –2.
Put all the these values in the above expression.
= 4 × 2 × -6 + 5 × -6 × -2
= -48 + 60
= 12
Therefore the value of expression 4ab + 5bc be 12 .
(when a = 2, b = –6, c = –2 be -12)
