5x-7=4x-1
5x-4x=1x
1x-7=1
7+1= 8
1x=8 then divide 1 and 8 which shows x=8
Answer:
(5a-2)(5a-2) or (5a-2)^2
Step-by-step explanation:
25a^2-20a+4
factor out the trinomial,
(5a-2)(5a-2)
Find two numbers that when they multiply, you get the third term, which is 4 in this case. And when they add up, you get the second term, which is -20 in this case.
Answer:
The function given by will have a range of y < 3.
Step-by-step explanation:
The function given by will have a range of y < 3.
This is because, for any real values of x, the term will have a negative value. If we put x = 1, then, = - 2, and for x = -1, then = - 0.5.
That means for all real x.
Hence, < 0 + 3
⇒ y < 3 for all real x. (Answer)
A+B: the matrix with same dimension a A and B, the element in row i and column j is: Aij+Bij
Same for A-B, but with Aij-Bij
