Answer:
10 hours
$43
Step-by-step explanation:
Given that:
Jonny:
Shoe rental = $13
Fee per hour = $3
Dustin :
Shoe rental = $3
Fee per hour = $4
Number of hours bowled is the same
Let number of hours bowled = x
$13 + 3x = $3 + 4x
3x - 4x = $3 - $13
-x = - 10
x = 10
Number of hours each bowled = 10
Amount spent :
Jonny:
$13 + 3x = $13 + $3(10) = $13 + $30 = $43
Dustin :
$3 + 4x = $3 + $4(10) = $3 + $40 = $43
Answer:
y=-3x-11
Step-by-step explanation:
y-4=-3(x+5)
y-4=-3x-15
y=-3x-11
Answer:
find derivative of function
sub in x value of point to find gradient of tangent
put gradient into y=(gradient)x+c
Sub in point and solve for c
you have found the equation of the tangent.
