Answer: did u get it ? what was it
Step-by-step explanation:
First lets find the range of -2 sqrt(x - 3) + 8
x cannot be < 3 or f(x) would not be real
when x = 3 f(x) = 8
and for all other values of x f(x) will tend to - infinity
range is [8, - infinity)
if we do same for the 4 choices we'll see that - sqrt(x - 3)+8 will have same range
Answer:
3 paperback books
Step-by-step explanation:
Let the number of paperback Kate bought be a and the number of hard books be b.
Given that she bought 5 books then
a + b = 5
Also, If Kate paid 7d dollars then
a * d + b * 2d = 7d
Divide through by d
a + 2b = 7
Hence we have 2 equations
a + b = 5
a + 2b = 7
subtract the first from the second
2b - b = 7 - 5
b = 2
since
a + b = 5
a + 2 = 5
a = 5 - 2
= 3
Recall that the number of paperback she bought is a hence this is 3
Answer:
