Step-by-step explanation:
Multiply by the LCD (bd)
Answer: -1
Step-by-step explanation:
Find the two coordinates first.
In this case, they are (-4, 1) and (-2, -1).
Use the following formula to calculate slope:

Substitute in the coordinates:
=
= -1
ok, i will help you.
For the first equation, we have points
(-1, -4)
and
(1, -1)
we also know the y-intercept is
(0, -2)
we can make systems of equations to solve for the equation of this exponiental function
y=ab^x
-1=ab
-2=a*1
a=-2
-1=-2(b)
b=1/2
The exponiental fufnction here is y=(-2)(1/2)^x
2nd equation
(0, 6)
(1, 12)
12=ab
6=a*b^0=6
a=6
12=6(b)
b=2
2nd equation is
y=6(2)^x
He has $4.40, the quarters, nickels, and dimes added up to $1.80, subtract that from $6.20 and you get $4.40
