Answer:
14 10 cent coins
Step-by-step explanation:
Assumption method:
Assume all are 10 cent
10x48=$4.80
8.20-4.80=3.40
10x47=$4.70
1x20=$0.20
$4.70+$0.20=$4.90
Gap= $3.40
Difference=$4.90-$4.80=$0.10
Gap÷Difference= $3.40÷0.10=34 20 cent coins
48-34=14 10 cent coins
I think its like this.

If f(x) is an exponential function where f(-2) = 1 and f(7) = 63, then find the
value of f(1), to the nearest hundredth.
An exponential function is represented as: [tex]\mathbf{f(x) = ab^x}[/tex]
The value of f(1) is 3.95
f(-2) = 1 means that:
[tex]\mathbf{ab^{-2} = 1}[/tex]
f(7) = 63 means that:
[tex]\mathbf{ab^{7} = 63}[/tex]
Divide both equations
[tex]\mathbf{\frac{ab^7}{ab^{-2}} = \frac{63}{1}}[/tex]
Apply law of indices
[tex]\mathbf{b^9 = 63}[/tex]
Take 9th root of both sides
[tex]\mathbf{b =1.58}[/tex]
Make a, the subject in [tex]\mathbf{ab^{-2} = 1}[/tex]
[tex]\mathbf{a = \frac{1}{b^{-2}}}[/tex]
[tex]\mathbf{a = b^2}[/tex]
Substitute [tex]\mathbf{b =1.58}[/tex]
[tex]\mathbf{a = 1.58^2}[/tex]
[tex]\mathbf{a = 2.50}[/tex]
So, we have:
[tex]\mathbf{f(x) = ab^x}[/tex]
[tex]\mathbf{f(x) = 2.50 \times 1.58^x}[/tex]
Substitute 1 for x
[tex]\mathbf{f(1) = 2.50 \times 1.58^1}[/tex]
[tex]\mathbf{f(1) = 3.95}[/tex]
Hence, the value of f(1) is 3.95

(3n-4n+1)-(8n-4n+17)
Answer:

Hey there!
5x - 50 + 2x + 80 - x = 180
COMBINE the LIKE TERMS
= 6x + 30 = 180
SUBTRACT 30 to BOTH SIDES
6x + 30 - 30 = 180 - 30
CANCEL out: -30 - 30 because that gives you 0
KEEP: 180 - 30 because it helps solve for the x-value
6x = 180 - 30
180 - 30 = 150
NEW EQUATION: 6x = 150
DIVIDE 6 to BOTH SIDES
6x/6 P 150/6
CANCEL out: 150/6 because that gives you the result of the x-value
x = 150/6
SIMPLIFY IT!
x = 25
Therefore, your answer is: x = 25

Answer:
neither
Step-by-step explanation:
put the first equation in slope intercept form
x-2y=-1
-2y= -x -1
y = 1/2x +1/2
the slope is not the same, and it is not the opposite, so it is neither
