Answer:
x = -1
Step-by-step explanation:
-x+4y= -17
-x= -17-4y multiply everything by -1
x=17+4y
-6X-2y=2
-6(17+4y) - 2y=2
-102-24y-2y=2
-26y=2+102
-26y=104
y= -104/26
y= -4
x=17+4y
x=17+4•4
x=17+16
x=33
The answer is D:)
the reason why is because on September 17, 1787, the Constitution of the United States of America was signed by 38 of the 41 delegates present at the conclusion of the convention.
Answer:
4x^2 -8
Step-by-step explanation:
f(x)=3x^2-9
g(x)=x^2+1
(f+g)(x)=3x^2-9 +x^2+1
Combine like terms
= 4x^2 -8
The architect's puzzle is to build as many different houses as possible from four cubes given that the cubes must be placed face to face. Orientation on the 'block of land' determines whether two houses are the same. If a house could be rotated on the block to fit the shape of another house, then the two are the same.
