Answer:
(-6,4)
Step-by-step explanation:
since (y) is already solved, you would substitute the y in the second equation so:
y=4 and -4x-3y=12
-4x-3(4)=12 ( Distribute )
-4x-12=12.
( add 12 to both sides to remove the constant )
-4x=24
( divide both sides by the coefficient so -4)
x=-6
now write it as an ordered pair (x,y): (-6,4)
Answer:
Carl statement is correct
Step-by-step explanation:
Absolute value is the value of the number without considering the sign of the number.
Absolute value of two integer can be same
example absolute value of -3 and 3
absolute value of |-3| = 3
absolute value of | 3 | = 3
hence, two integer have same absolute value.
so, Carl statement is correct about the absolute value.
Cross multiply
2x(3x-4) = 3(x+2)
5x - 8x = 3x + 6
-3x= 3x+6
x = 6
I think
Answer:
[4, -1]
Step-by-step explanation:
Using the Elimination Method:
3x + y = 11
5x - y = 21
__________
8x = 32
__ ___
8 8
x = 4 [Plug this back into both equations to get the y-coordinate of -1]; -1 = y
The <em>y</em>'s are already <em>additive</em><em> </em><em>inverses</em><em> </em>[result in 0], canceling each other out.
