Maria solved the equation -5n = -9. Her answer was n = 1. She is fairly confident about her answer, but wants to do a quick check of her solution using estimation.
The solution to an equation is the true value of the equation
So, Maria's solution is incorrect
The equation is given as:
[tex]-5n = -9[/tex]
And the solution is given as:
[tex]n = 1[/tex]
To determine if her solution is correct, then she needs to substitute her solution in the given equation.
In other words, substitute 1 for n in [tex]-5n = -9[/tex]
[tex]-5 \times 1 = -9[/tex]
Multiply -5 and 1
[tex]-5 = -9[/tex]
The above equation is false.
This is so, because -5 does not equal -9
i,e, [tex]-5 \ne -9[/tex]
Hence, Maria's solution is incorrect

A 14
OB. 18
OC 21
OD 24
Interest is the amount of money added on an amount invested. He have doubled her investment after 18 years
Compound interestThe formula for calculating the compound interest is expressed as
A = P(1+r)^t
Given the following parameters
P = $500
r = 4%= 0.04
A= $1000 (doubled)
Substitute
1000 = 500(1+0.04)^t
2 = 1.04^t
t = ln2/ln1.04
t= 17.67 = 18years
Hence he have doubled her investment after 18 years

your answer dude mark me as brainelist give me thanks
Answer:
5x + 16
Step-by-step explanation:
3(x+2) +2 ( x+5)
divide the expression into 2 separate ones:
3(x + 2) and 2(x + 5 )
Now for 3( x + 2 ) Multiply 3 with x and 3 with 2. This gives:
3x + 6
Now for 2( x + 5 ) Multiply 2 with x and 2 with 5. This gives:
2x + 10
Now since there is a '+' sign between 3( x + 2 ) and 2( x + 5 ), the expression will be:
3x + 6 + 2x + 10
You can simplify the like terms together:
3x + 2x + 10 + 6
= 5x + 16

The value of Melissa's Jeep is $28,000 and is depreciating at a rate of 14% per year. Use an exponential function to find the value of the Jeep after 6 years. Round to the nearest cent. *
Answer:
$12,088
Step-by-step explanation:
Value = $28,000
Rate, r = 14% = 0.14
Time = 6 years
Using an exponential function :
A = Pe^-rt
P = initial value
A = final worth
A = 28000*e^-(0.14*6)
A = 28000 * e^-0.84
A = 28000 * 0.4317105
A = 12087.894
Worth after 6 years = $12,088

Answer:
y = 2327.49 ---> 25 hrs
starting plot points (0,640) and ending (25, 2327.49)
Step-by-step explanation:
b = 640
r = 5.3% = 0.053
t = 25
y = 640 ( 1 + 0.053)^25
y = 640 ( 1.053)^25
y = 2327.49 ---> 25 hrs
starting plot points (0,640) and ending (25, 2327.49)
sin0=? cos0=? tan1=?
Answer:
See explanations below
Step-by-step explanation:
Sin 0 = x
0 = arcsinx
Since 0 the angle is positive and lies in the 1st and second quadrant, sin 0 = 0 (in the first quadrant)
cos 0 = 1 (by punching the calculator)
tan 1 = 0.0174
All this values can easily be gotten directly from calculators
