Answer:
There are two real roots because b²>4ac
in the equation, b²= 9² = 81.
4ac = 4×-4×-12= 72
Answer:
y=-9x+51
Step-by-step explanation:
-9x+45=y-6
add 6 to both sides to get
-9x +51=y
Answer:
y: 139 x: 139 too
Step-by-step explanation:
Answer:
the value of a and b is 68
Step-by-step explanation:
the other half is 224 so you minus 360 from 224 which will give us 136 then you divide by 2 to get a and b.
5x-2+x=9+3x+10
6x-2=3x+19
3x=21
x=21/3
x=7
