Answer:
A
Step-by-step explanation:
- to find x we use tan 60 = x/7
- rearrange, tan60*7 = x, x = 
- now you have two sides so you can use pythagoras to find z
y^2 + x^2 = z^2
z = 
z = 14
Answer:
y = x - 3
Step-by-step explanation:
y = mx + b
m is slope of a line, because the line is parallel to the line y = x - 5, slope should be the same, so m = 1
y=1*x + b
To find b, we have the point (1, -2)
-2 = 1 +b
b = -3
So line has the equation y=x - 3.
Answer:
C
Step-by-step explanation:
Rate of change is the slope
Function A:
Slope = change in y/Change in x
= (9-3)/(3-0) = 6/3 = 2
Function B:
Clearly the slope is 3
(y = mx + c, m is the slope)
Rate of change of B is more than A
