Answer:
note :
The equation of a linear function in point-slope form is y – y1 = m(x – x1)
The point is A (x1 , y1)
Step-by-step explanation:
in this exercice : y - 4 = 5 +(1/2)x
y - 4 = 0.5 ( x - 5/0.5)
y - 4 = 0.5( x - 10).....
note : the standard forme is : y = ax +b
in this exercice : y = (1/2)x+9
Answer:
the son had $20 and the father had $200
Step-by-step explanation:
20 x 10 = 200
200 + 20 = 220
F (x)= x+12 is the inverse of the function
For x, the answer is x >= -(3 - y)/2, for y it's y <= 2x -3.
