Answer:
2x + 15
Step-by-step explanation:
When you subtract an expression from another expression, it will be on the right side of the subtraction sign.
(4x + 9) - (2x - 6)
First, let's distribute the negative sign.
(4x + 9) - 2x + 6
Now combine like terms.
4x - 2x + 9 + 6
2x + 15
This is the fully simplified expression.
Hope this helps!

Answer:
all work is shown and pictured
Since we are given that the relationship between x and y
is linear. Therefore this means that the given equation takes the form of:
y = m x + b
where,
b is the y intercept of the equation
m is the slope of the equation
However we should take note that the slope m is directly
proportional to the coefficient of correlation. Since our coefficient of
correlation is negative, this only means that the value of y is decreasing with
increasing x, hence plot of y and x is descending with increasing x.
Furthermore, this also tells that for every 1 unit increase of x, there is a
0.75 units decrease of y.
