Y= -10x + 190
In using a linear function, follow the pattern y=mx + b.
In this scenario, the m (which represents slope) is -10 since $10 is taken away every time. The b(which represents y-int) is 190 because you start with 190 (x=0)
Answer:
Step-by-step explanation:
<h3><u>TO SOLVE:</u></h3>
Isolate by the x on one side of the equation.
<h3><u>SOLUTIONS:</u></h3>
First, subtract 3x from both sides.
Solve.
Sides are NOT equal.
Therefore, there are no solutions.

1 ice cream cone: $2.75
2 ice cream cones: 2 * $2.75 = $5.50
7.5% of $5.50 =
= 0.075 * $5.50

Step-by-step explanation:
The simple regression model is:
, then 
.
The statistic calculated for the hypothesis test of statistical significance, for the slope, in a simple regression model is given by:
with 
the slope estimator, 
the value of slope in the null hypothesis and 
the standard error of the slope. Thus,
