You move the +4a to the left side of the equal sign and that becomes a negative
9a-2-4a=c
You move -2 to the right side of the equal sign and that becomes a positive
9a-4a=c+2
Combine like terms
5a=c+2
Divide by 5 from each side
a=(c+2)/5
Answer:
The first one is equivalent, the other two are not
Step-by-step explanation:
6^(t^2-2t)
(6^(t^2))(6^(-2t))
(6^t^2)(1/36)^t
Answer:
Step-by-step explanation:
hello : y= 4x² + 5x + 2
the x-intercepts when y=0 means : 4x² + 5x + 2=0
a=4 b= 5 c=2
∆ = b²- 4ac ∆ = (5)²- 4(4)(2) =25-32 = -7
∆ < 0 no reals solutions no x-intercepts
