Answer:
35 two pointers, 18 one pointers
Step-by-step explanation:
equations:
x + y = 53
x + 2y = 88
solving them:
y = 35
x = 18
Answer: True
The domain and range swap when you go from the original function to the inverse. This is because the x and y swap places. Recall that the domain is the set of possible x inputs and the range is the set of possible y outputs.
Always
a=b
subtract c from each side
a-c = b-c
Answer:
4x+3y-10=0
Step-by-step explanation:
first find the gradient of the line that is perpendicular to the line of interest.
y2-y1/x2-x1
3--3/6--6
=3+3/6+6
=9/12
3/4
The gradient of the line of interest is the negative reciprocal of 3/4. Therefore m is -4/3
next, substitute information into
y-y1=m(x-x1)
y-2=-4/3 (x-1)
multiply both sides of equation by 3
3y-6=-4 (x-1)
expand brackets
3y-6=-4x+4
rearrange in general form
4x+3y-10=0
