Answer:
Gradient = 2
Step-by-step explanation:
Gradient of a line = Slope of the line
Since, slope of a line passing through two points 
and 
is given by,
Slope = 
Given line in the graph passes through two points (1, 0) and (2, 2)
Therefore, slope or gradient of the line = 
= 2
Gradient = 2 will be the answer.
Solve the second equation for y so that you can substitute it in for y in the first equation..
y = 5x - 4
Substitute:
3x + (5x - 4) = 1
Step-by-step explanation:
7^2+8^2=113
Then square root 113 which is 10.63 to 2.d.p
So x=10.63
Answer:
C
Step-by-step explanation:
A&B are wrong because they imply that x can equal 250, which it can't, it has to be less than 250 so the max x can be is 249.
D is wrong because it is talking about greater than which it is not. It is less than
C is correct
