Sladkaya [172]

You are correct

for example f(1) = 3

and f(2) = f(2-1) - 2

= f(1) - 2

= 3 - 2 = 1

$A.\\-vp+40 < 95\qquad\text{subtract 40 from both sides}\\\\-vp < 55\qquad\text{change the signs}\\\\vp > -55\qquad\text{divide both sides by p}\\\\If\ p > 0\ then\ v>-\dfrac{55}{p}.\\\\If\ p < 0\ then\ v < -\dfrac{55}{p}$

$B>\\8w-3r=45\qquad\text{subtract 8 from both sides}\\\\-3r=-8w+45\qquad\text{change the signs}\\\\3r=8w-45\qquad\text{divie both sides by 3}\\\\r=\dfrac{8w-45}{3}$

Find the least whole number that can make this statement true 15<_*400

Tatiana [17]

Answer:

The least whole number is the number 1

Step-by-step explanation:

we have

$15 < (x)400$

Remember that

<u>Whole numbers</u> are positive numbers, including zero, without any decimal or fractional parts [0,1,2,3,4,5,6,...]

Solve the inequality for x

Divide both sides by 400

$15/400 < x$

$0.0375 < x$

Rewrite

$x > 0.0375$

therefore

The least whole number is the number 1

Simplify the expression.

levacccp [35]

Hi there! The answer is 30.

We need to use PEMDAS to simplify.
P = parenthesis
E = Exponents
M = Multiply
D = Dividing
A = Adding
S = Subtracting

$10(4 \times 10 \div ( {6}^{2} - {4}^{2} ) + 1)$
First find the exponents inside the middlest parenthesis.

$10(4 \times 10 \div (36 - 16) + 1)$
Now add inside the parenthesis.

$10(4 \times 10 \div 20 + 1)$
Multiply inside the parenthesis that are left.

$10(40 \div 20 + 1)$
Divide inside the parenthesis

$10(2 + 1)$
Add inside the parenthesis.

$10(3)$
Multiply.

$30$
~ Hope this helps you!
