How am I so supposed to solve the question without the picture?
Answer:
(-7, -12)
Step-by-step explanation:
4x-3y=8
5x-2y=-11
Is there any of the like terms can be added and the result will be 0? No, so we have to multiple one OR both of the equations to make that one number do that.
(I will try to remove the y like terms so i will multiple both of them by the opposite so both of the ys will be 6)
2(4x-3y=8)
-3(5x-2y=-11)
8x-6y=16
-15x+6y=33
(now the easy part… cancel the 6s and add the equations)
8x+(-15x)=-7x
16+33=49
-7x=49
(divide 49 by -7)
x=-7
Replace x in any of the equations and you’ll get the y value.
4x-3y=8
4(-7)-3y=8
-28-3y=8
-3y=36
y=12
Threfore, there is one solution which is….. (-7,-12)
Answer:
2
A)-7y^3-3y^2-2y-8
B)-7x^3y^3-12x^2y^2-xy
C)2xy^3+3xy^2-5
3
A)14x^2
B)15a^2+30ab
Step-by-step explanation:
The correct answer is
Triangle A
Triangle D
This is the answer because they are the same triangle but only triangle D is flipped upside-down.
