viva [34]3 years ago
5 0

Answer:

First blank = 236

Second blank = 60

Third blank = 656

Step-by-step explanation:

For first blank; n = 20

f(n) = 7(20) + 96

= 236

For second blank; f(n) = 516

⇒ 516 = 7n + 96

⇒ n = 60

For third blank; n = 80

f(n) = 7(80) + 96

= 656

Pleeeeease help me!!!

Hello!

We solve this algebraically

y + 6 = 3/2(x - 4)

We distribute the 3/2

y + 6 = 3/2x - 6

If you work with decimals easier we can make 3/2 into a decimal

y + 6 = 1.5x - 6

Add 6 to both sides

y + 12 = 1.5x

subtract y from both sides

1.5x + -y = 12

Hope this helps!

Find the given higher-order derivative.<br><br> f''(x) = 9- 3/x<br><br> f'''(x)=
Genrish500 [490]

Answer:

f'''(x)=\frac{3}{x^{2}}

Step-by-step explanation:

We are given with Second-order derivative of function f(x).

f''(x)=9-\frac{3}{x}

We need to find Third-order derivative of the function f(x).

f''(x)=9-\frac{3}{x}=9-3x^{-1}

We know that,

f'''(x) = (f''(x))'

So,

f'''(x)=\frac{\mathrm{d}\,f''(x)}{\mathrm{d} x}

f'''(x)=\frac{\mathrm{d}\,(9-3x^{-1})}{\mathrm{d} x}

f'''(x)=\frac{\mathrm{d}\,9}{\mathrm{d} x}-\frac{\mathrm{d}\,3x^{-1}}{\mathrm{d} x}

f'''(x)=0-3\frac{\mathrm{d}\,x^{-1}}{\mathrm{d} x}

f'''(x)=-3(-1)x^{-1-1}

f'''(x)=3x^{-2}

f'''(x)=\frac{3}{x^{2}}

Therefore, f'''(x)=\frac{3}{x^{2}}

9x-3+10-5x=9x-5x-3+10 the question is: list which of the associative and commutative properties are being used
Nataliya [291]

The given equation is:

9x-3+10-5x = 9x-5x-3+10

1. Associative property of addition: when three or more numbers are added the sum is same regardless of the grouping of the numbers.

(9x -5x) + (10-3) = (9x -5x) + (10-3)

2. Commutative property of addition: This property states that the numbers can be added in any order without changing the resulting answer/ sum.

9x-3+10-5x= -3+10+9x-5x
