Answer:
x = -10
Step-by-step explanation:
first you multiply both sides by -3
x + 7 = -3
then you subtract 7 from both sides
x = -10

It's 8! range is just the greatest value minus the lowest value
(=^_^=)
42 (1- 25/100) = 63/2 = 31.5 dollars
answer is $31.50

Answer:
see explanation
Step-by-step explanation:
- 7x = - 105 ( divide both sides by - 7 )
x = 15
A line with equation x = c is a vertical line parallel to the y- axis passing through all points with an x- coordinate of c
Thus x = 15 is a vertical line passing through all points with an x- coordinate of 15
Plot (15, 0 ) , (15, 3 ) and (15, - 3) and join a straight line through them for graph
First find the secant line. The slope of the secant line through
(when
) and
(when
) is the average rate of change of
over the interval

:
The tangent line to
will have a slope determined by the derivative:
Both the secant and tangent will have the same slope when
, or when
