Answer:
<h2>
Larger number = 10</h2><h2>
Smaller number = 5</h2>
Step-by-step explanation:
Let larger number be x
Let smaller number be y
---> equation (i)
-----> equation (ii)
Equate equation (i) and (ii),
Move variable to L.H.S and change its sign:
Similarly, Move constant to R.H.S and change its sign
The difference sign (-) will be cancelled on both sides
Putting the value of y in equation (ii) in order to find the value of X ( larger number)
Plug the value of y
Calculate the product
Hence,
Smaller number = 5
Larger number = 10
Hope this helps..
Best regards!!
Answer:
in (x,y), it becomes (-x,y)
Step-by-step explanation:
Answer:
The dimensions are 9m by 18 m
Step-by-step explanation:
The perimeter will be
x+y+x for the three sides ( the wall is the fourth side)
2x+y = 36
Solving for y
y = 36-2x
The area is x*y and we want it maxed
A =x( 36-2x)
36x-2x^2
Taking the derivative
dA /dx = 36 - 2 * 2x
Setting this equal to zero to find the max
0 = 36 - 4x
4x = 36
Divide by 4
x = 36/4
x = 9
Now find y
y = 36-2x
y = 36 - 2*9
y = 36 - 18
= 18
The dimensions are 9m by 18 m
C? i’m pretty sure sorry if it’s wrong
Y-4=5(x-(-2)) this is the equation. I hope this helps and have a good day!
