The answer is -100 (10*10)- (-10*-10) - (10*10)
Answer:
± 8i
Step-by-step explanation:
note that 
= i
using the rule of radicals
• 
× 
⇔ 
, hence
= ± 
= ± 
× = ± 8i
Answer:
x = 1 and x = 9
Step-by-step explanation:
the known solutions are simply the values of x which causes the SAME number to show up in f(x) and g(x).
if we go down the table, we see that for x = 1, the same number 14 shows up for both f(x) and g(x), hence x=1 is a solution.
the same occurs for x = 9 giving 6 as the same solution for f(x) and g(x)
no other values of x causes this to occur.
hence the 2 known solutions are x = 1 and x = 9
18. All you need to do is divide.
First, you would need to multiply 25×3 since each student gets 3 markers, which equals out to 75 markers total. Then, you must divide since each pack has 8 markers, resulting in 75÷8= 9.375
The answer is 10 packages of markers.
Hope this helped.
