Answer:
Equation:
A is correct
Step-by-step explanation:
Given: The graph of a function on x-y coordinate plane.
y-intercept: (0,1)
Graph starts from II quadrant touches x-axis at infinity.
End in I quadrant increases gradually.
This is property of exponential function.
y-intercept: (0,1)
Passing point: (1,3)
b=3
Equation of graph:

Answer:
The amount spent on the refrigerator is $ 800 .
Step-by-step explanation:
Given as :
The amount spent on television = $ 1600
Le The total amount in the account = $ A
so, The amount left in account after spent on television = $ A - $ 1600
The amount spent on refrigerator = × ( A - 1600 )
The amount left in his saving account = × A
Now, According to question
A - ( 1600 + × ( A - 1600 ) ) =
× A
Or, A - × A = 1600 +
× ( A - 1600 )
Or, × A = 1600 +
× A -
× 1600
or, × A -
× A = 1600 - 640
Or, × A = 960
or, × A = 960
∴ A =
I.e A = 3600
So, The amount in the saving account is $3600
∵ , The amount spent on refrigerator = × ( 3600 - 1600 )
Or, The amount spent on refrigerator = × 2000
I.e The amount spent on refrigerator = $ 800
Hence The amount spent on the refrigerator is $ 800 . Answer
2x + 7 = 1
Subtract 7 on both sides
2x = 1 - 7
2x = -6
Divide both sides by 2
x = -6/2
x = -3
Your answer is
Subtract 7 on both sides
2x = 1 - 7
2x = -6
Divide both sides by 2
x = -6/2
x = -3
Your answer is
