Answer:
-2 ≤ x ≤ 6
Step-by-step explanation:
For function f:
x - 7 ≤ 0 and x ≥ 0
For function g:
x + 2 ≥ 0 and x - 5 ≤ 0
The sum of the f + g:
x - 7 + x - 5 ≤ 0
2x - 12 ≤ 0
2x ≤ 12
∴ x ≤ 6
Also, x + 2 ≥ 0
x ≥ -2
Hence, -2 ≤ x ≤ 6
Answer:
the answer is 55 which its B
because you multiplay 22%of 250
you first have to move the decimal two times
like this .22 now you multiplay
.22×250=you will get 5500 but remember you plug in the decimal and move it two time
which it is 55.00 so its 55
Answer:
The answer is d (-21/2 , 2)
Step-by-step explanation:
That's where the lines meet up
Step-by-step explanation:
a=2
b=-7
c=-15
-(-7)+-sq root (-7)²-4(2)(-15) / 2(2)
7 +- sq root 169 / 4
7+- 13 / 4
7+13 / 4, 7-13 / 4
x=5 x=-3/2
