Like triangles sides they help by using the sides
Answer:
(2x-3)(2x+1)
Step-by-step explanation:
4x^2 - 4x - 3
we need two numbers that give 12 when multiplied and 4 when subtracted
the numbers are 6 and 2 because 6*2=12 and 6-4=4.
4x^2 - (6-2)x -3
4x^2 -6x +2x -3
take common
2x(2x -3)+1(2x-3)
take (2x-3) as common
(2x-3)(2x*1 + 1*1)
(2x-3)(2x+1)
Answer:
y = 0.1(4^x)
Step-by-step explanation:
An exponential function can be written as ...
y = a(b^x)
where 'a' is the y-intercept, and 'b' is the ratio of terms with consecutive x-values.
The table tells us a=0.1, and b=0.4/0.1 = 4. The equation is ...
y = 0.1(4^x)
