Answer: $z$

Step-by-step explanation:

To solve this problem you must apply the proccedure shown below:

Add 8.2 to both sides of the inequality. Then, you obtain:

$-1.2z-8.2+8.2>-9.7+8.2\\-1.2z>-1.5$

Now you must divide both sides by -1.2, as you can see below:

$\frac{-1.2z}{-1.2}>\frac{-1.5}{-1.2}$

(The direction of the sign will change).

Therefore, you obtain the following solution:

$z$

Use the Distributive Property to simplify the expression.I GIVE BRAINLEST AWNSER <br> 6(6+y)

ivanzaharov [21]

Answer:

36+6y

Step-by-step explanation:

you have to multiply 6 on 6+y because distributive property basically means to share out so you do 6(6)+(6)y

6(6) equals 36 (6x6) and 6(y) is just 6y

36+6y

wyatt opend a savings account 4 years ago. the account earns 4%interest compounded quarterly if the current balance is $1,000.00

Doss [256]

Answer:

He deposited initially $852.82

Step-by-step explanation:

The rule of the compound interest is $A=P(1+\frac{r}{n})^{nt}$ , where

A is the new amount

P is the initial amount

r is the rate in decimal

n is the period of the time

t is the time

∵ Wyatt opened a savings account 4 years ago

∴ t = 4

∵ The account earns 4% interest compounded quarterly

∴ r = 4% = 4 ÷ 100 = 0.04

∴ n = 4 ⇒ compounded quarterly

∵ The current balance is $1,000.00

∴ A = 1,000

→ Substitute these values in the rule above to find P

∵ 1,000 = $P(1+\frac{0.04}{4})^{4(4)}$

∴ 1,000 = $P(1+0.01)^{16}$

∴ 1,000 = $P(1.01)^{16}$

→ Divide both sides by $(1.01)^{16}$

∴ 852.8212622 = P

→ Round it to the nearest cent (2d.p)

∴ P = 852.82

∴ He deposited initially $852.82
