Answer:
y=2x+10
Step-by-step explanation:
In line equations its helpful to write your line in the form y = ax + b. This helps because a is always the gadient of the line and b is always the y intercept.
In this case it is y=2x+3
All parallel lines have the same gradient. The gradient of this line = 2.
If the line crosses the x axis at x=-5, then when x =-5 y = 0.
If you put all this in the form y =ax + b you get 0 = 2(-5) +b
So all you need to do to find b is rearrange. b = 10.
Therefore your line has gradient 2 and y intercept 10.
y = 2x + 10
Answer:
0.5* sin(x)
Step-by-step explanation:
As well known sin (2A)= 2sin(A)*cos(A)
As in our case A=x/2 => cos(x/2*sin(x/2)=1/2*sin(x)=0.5*sin(x)
Answer: You need to calculate the Area because it is a space being occupied.
Step-by-step explanation:
3/4 < 33/40 because 30/40 < 33/40
3/4 times 1 1/2 = 1 1/8
Hope this helps!
