Answer:
y = 4x - 1
Step-by-step explanation:
Assuming you require the equation of the line.
The equation of a line in slope- intercept form
y = mx + c ( m is the slope and c the y- intercept )
Here m = 4 and c = - 1, thus
y = 4x - 1 ← equation of line
Answer:
B
Step-by-step explanation:
A geometric sequence has a common ratio r between consecutive terms
r = 
= 
= ...
= 2
= 2
= 2
There is a common ratio of 2 between consecutive terms.
Hence sequence is geometric → B
Answer:
x^2 + (x + 2)^2 = 202
x^2 + x^2 + 4x + 4 = 202
2x^2 + 4x + 4 = 202
2x^2 + 4x - 198 = 0
x^2 + 2x - 99 = 0
x = -2/2 ± √((2/2)^2 - (-99))
x = 9 or x = -11
-11 is not a positive number so the number is 9.
The equation out of this is; what is 250/100 of a number x = 90?
=> Division of 250 by 100 gives 2.5.
=> Now multiply 2.5 by a number x resulting to 2.5x on the L.H.S.
=> make x the subject and come up with x = 90/2.5.
answer is 1/36.
