ANSWER
B. x=3,y=2
EXPLANATION
The given equations are
and
We add the two equations to eliminate y.
This implies that that:
Simplify:
Divide both sides by 2.
We put x=3 into any of the equations to find y.
Let us substitute x=3 into equation (1) to get:
Divide both sides by -3 to get;
The solution is therefore x=,y=2.
Answer:
Jul 9, 2017 - First lets find the range of -2 sqrt(x - 3) + 8x 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)
Step-by-step explanation:
Answer:
Hence Perimeter for new rectangle will be 27 units .
Step-by-step explanation:
Given:
A rectangle with enlarged factor of 1.5
L=7 and W=2
To Find:
Perimeter for new rectangle
Solution:
First calculate the new dimensions for new rectangle ,
Given that original length and width as 7 and 2 respectively and it is increasing by 1.5 times of the original ones
So
New length =1.5 *L
=1.5 *7
=10.5 units
And for width,
New width=1.5 *W
=1.5 *2
=3
Hence New dimensions are 10.5 and 3 units .
So perimeter of new rectangle =2(New length + New breadth)
=2(10.5+3)
=2(13.5)
=27 units
Step-by-step explanation:
buena suerte con todo....
