Answer:

Least possible value of b is 9.

Step-by-step explanation:

It is given that $7b-8>4b+16$ and b is an odd integer.

We need to find the least possible value of b.

We have,

$7b-8>4b+16$

Isolate variable terms.

$7b-4b>8+16$

$3b>24$

Divide both sides by 3.

$b>8$

Since b>8 and b an odd integer, therefore the possible values of b are 9, 11, 13, 15, ... .

Hence, the least possible value of b is 9.

Write the explicit formula that represents the geometric sequence -2, 8, -32, 128

lora16 [44]

$a_{1}=-2 \\ \\ a_{2}=8 \\ \\ q= \frac{a_{2}}{a_{1}} \\ \\ q= \frac{8}{-2}=-4 \\ \\ a_{n}=a_{1}*q^{n-1} \\ \\ a_{n}=-2*-4^{n-1}$

A father is four times as old as his son. In 3 years, the father will be three times as old as his son. How old is each now?

matrenka [14]

4x+3=3(x+3)

4x+3=3x+9

4x-3x=9-3

x=6

So The Father is 24 and the Son is 6

Look at the example problem. Explain how you know 1 5/8 is little greater than 1 1/2.

natita [175]

Convert the fractions so both fractions have the same denominator. 1 1/2 is equal to 1 4/8 (1/2 * 4/4= 4/8). 1 4/8 is smaller than 1 5/8.
