Answer:
y=-2x+2
Step-by-step explanation:
Slope (m) =
=
=
= -3
y - y₁ = m(x - x₁) ; where (x₁, y₁) is the point and m is the slope
y - 15 = -3(x + 2)
y - 15 = -3x - 6
y = -3x + 9
Answer:
Number of dogs = 6
Number of burgers = 11
Step-by-step explanation:
Number of dogs = x
Number of burgers = 2x - 1
Cost of a dog = $ 1.50
Cost of 'x' dogs = 1.5x
Cost of a burger = $ 2
Cost of (2x - 1) burger = (2x -1) * 2 = 2x *2 - 1*2
= 4x - 2
Total amount collected = $ 31
1.5x + 4x - 2 = 31 {add 2 to both sides}
1.5x + 4x = 31 + 2
1.5x+ 4x = 33
5.5x = 33
x = 33/5.5
x = 6
Number of dogs = 6
Number of burgers = 2*6 - 1 = 12 - 1 = 11
ANSWER
The answer is D
EXPLANATION
Let the exponential function be of the form
Each box on both the x and y axes is one unit.
The graph passes through the point
.
This point must satisfy the equation above.
This implies that,
The function now becomes,
The graph also passes through
We substitute this point too to get,
This implies that,
or
We substitute back to get,
The correct answer is D.
