Answer:
No solutions
Step-by-step explanation:
i did this via substitution so i hope it isn't a problem
3x+y=4
6x+2y=−4
Step: Solve 3x+y=4for y:
3x+y+−3x=4+−3x(Add -3x to both sides)
y=−3x+4
Step: Substitute−3x+4foryin6x+2y=−4:
6x+2y=−4
6x+2(−3x+4)=−4
8=−4(Simplify both sides of the equation)
8+−8=−4+−8(Add -8 to both sides)
0=−12
so there are no solutions
hope this helps!!
You may have $26 I not a genius but this is easy
3x4.35=13.05
13.05+5.65=18.7
18.7 Is your answer. Hope this helps!
The domain is the x-axis and the range is the y axis.
Example:
(-2,4) (6,7) (3,-8)
D:{-2,6,3}
R:{4,7,-8}
Step-by-step explanation:
(4x-5)(4x+5)
multiply each
4x×4x=16x^2
4x×5=20x
-5×4x= - 20x
-5×5= -25
16x^2+20x-20x-25
16x^2-25
