Answer:
19
Step-by-step explanation:
by replacing x and y with their given values ,
we get :-
=》2x + 7y - 10
=》(2 × 4) + (7 × 3) - 10
=》8 + 21 - 10
=》29 - 10
=》19
Answer:
x = 12 and y = 0
Step-by-step explanation:
Use elimination by adding the equations together.
-2x + 15y =-24
2x + 9y = 24
---------------
24y = 0
y=0
Then substitute y = 0 into one equation to find x.
-2x + 15(0) = -24
-2x + 0 = -24
-2x = -24
x = 12
diagonal for rectangle= sqrt( A^2 +b^2)
diagonal for square = sqrt(2) * Side
rectangle diagonal = sqrt (14^2+7^2) = 15.65 inches
square diagonal = sqrt(2) * 7 = 9.90 inches
9.9 *2 = 19.8
the diagonal of the rectangle is not two times the length of the square
Rate of change is 4. change of y over change of x= 20/5
