Answer:
9 = -2/-1 +b
9 = 2 + b
b = 9-2
b = 7
Step-by-step explanation:
Answer:84
Step-by-step explanation:because 7x12=84
Answer:

Step-by-step explanation:
Parent function of the square root function has been given as,
f(x) = 
If the graph of the given function is stretched vertically by the scale factor = g(x) = 
If the graph is shifted 3 units to the left,
h(x) = 
Since, the graph of the function passes through a point (-2, 2),

2 = k
Therefore, the function is
.
The perimeter of a rectangle is 40m and one side of it is 5m. What is the length of the other side using an equation?
Perimeter of the rectangle =2(l+ b)=40m
If one of its side b=5, then l = (40/2)-5
= 20–5
= 15 m Therefore
Length= 15 cm
Breadth =5 cm
