Answer:
There are 19 big marbles
Step-by-step explanation:
10a + 3b = 209
a = 3b
3b = 3b
10a + a = 209
11a = 209
a = 209/11
a = 19
To find the perimeter you do length + width so you do 12.4 + 5.9 to get the perimeter.
Answer:
(c) 45x³y
Step-by-step explanation:
Terms of a polynomial expression are separated by + or - signs. If there is only one term, there is no need to separate terms with such signs.
<h3>One term</h3>
The one-term expression is ...
45x³y
__
<em>Additional comments</em>
If the coefficient of a one-term expression is negative, there will be a leading minus sign. There won't be another term on the other side of that sign.
The given expressions appear to suffer from poor editing. Ordinarily, exponents are rendered using a superscript font, as the 3 is in the first expression. However, the second term of that expression is 1x2, which we understand to be 1x². If the 2 were intended as a multiplier, rather than an exponent, we would expect it to be combined with the coefficient 1 in that term to give (xy)³ -2x.
It is this assumption that leads us to write 45x3y as 45x³y. If that is not the intention of the given expression, it could be simplified to 135xy.
Ordinarily, if an exponent is not rendered in superscript font, we expect it to be identified by the caret (^) operator, as in 45x^3y.
Step-by-step explanation:
do u mean 1,932 divided by six?
Answer:
B- the domain of function A is the set of real numbers is greater than 0
The domain of the function B is the set of real numbers greater than or equal to 1
Step-by-step explanation:
The function A is 
By definition we know that the function is not defined for values of 
Therefore the domain of is:
All real numbers greater than 0.
Function B shown in the graph is a curve that goes in x from x = 1 to infinity.
Therefore it can be seen that the domain of this function is:
all real numbers greater than or equal to 1.
.
Therefore the correct option is B.
