HELP WHAT IS THE SLOPE!!!!!!

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

Answer:

C

Step-by-step explanation:

[tex] \sin(30) = \frac{8}{x} \\ x = \frac{8}{ \sin(30) } = 16 \\ \tan(30) = \frac{8}{y} \\ y = \frac{8}{ \tan(30) } = 13.85 = 8 \sqrt{3} [/tex]

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)

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:

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

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

Answer:

b=21/1.5

b=14

Interest is the amount of money added on an amount invested. He have doubled her investment after 18 years

The 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
