None of these are choices, because in order to make 20ths equal a 45th, it was to end in a 20,40,60,80, or ending in 00.
First off, the function above is incomplete, however, by the looks of it, likely a quadratic, anyway, the values "x" can safely take on would be all real numbers, thus -∞ < x < +∞
Answer:
(2,-1)
Step-by-step explanation:
Multiply first equation by 2:
10x + 2y = 18
Subtract the second equation from this so that the 2y terms cancel:
10x - 3x = 18 - 4
7x = 14
x = 2
Plug into first equation to find y:
5(2) + y = 9
10 + y = 9
y = -1
The answer is (2,-1)
Answer:
square root of 34
Step-by-step explanation:
ok so S is for Squared
Cs= As+Bs
5s+3s= Cs
25+9=34
Cs=34
C= square root of 34
to get C we need to square root Cs
square root of 34
so C is 5.83
Answer:
Katie will collect more than 100 seashells in 5 and a half days.
Step-by-step explanation:
Katie already has 34 seashells in her collection.
Each day, she finds 12 more seashells on the beach.
Let x be the number of days Katie is collecting seashells.
In x days, she will collect 12x seashells.
In total, she will collect
seashells.
Katie wants to collect over 100 seashells, so

Solve this inequality. Subtract 34:

Katie will collect more than 100 seashells in 5 and a half days.
