If we take the graph with x as number of years and y as amount of dollars in it as mentioned in the equation;
gradient of the graph/ slope (m) = Change in y / change in x
so if we take a certain portion of the graph
x is the number of years, since we know the growth for one year,
lets take change in x as 1 year
y is amount of dollars, the change in amount of dollars for one year is 28
therefore change in y is 28
m(slope) = 28(change in y) / 1 (change in x)
= 28
Answer:
The standard form of the expression (5a+2)(a+4) is 
.
Step-by-step explanation:
Here, the given expression is (5a+2)(a+4).
Now, (5a+2)(a+4) = 5a(a+4) + 2(a+4)
= 
=
or, 
Also, Standard Quadratic form is 
Hence, the standard form of (5a+2)(a+4) is .
Answer:
a) reflection across the x-axis, shift 8 units left
b) vertical stretch of 2, reflection across the y-axis, shift up 1
Step-by-step explanation:
The negative sign outside the square root represents a reflection across the x-axis, and the +8 inside represents a shift 8 to the left
The 2 outside the square root represents a vertical stretch of 2, and the negative sign inside the square root represents a reflection across the y-axis. The +1 at the end represents a shift up 1
