The rules about opositive and negative numbers include

Two like signs become a positive sign
Two unlike signs become a negative sign

<h3>How to illustrate the information?</h3>

It should be noted that two like signs become a positive sign. For example, (-2) × (-4) will be:

= (-2) × (-4).

= +8

Two unlike signs become a negative sign. This will be:

(-2) × (+4)

= -8

Select the all the numbers that would be apart of the pattern rule, "multiply by 6 and subtract 2

Cerrena [4.2K]

Answer:

A. 34; B. 40. D. 88

Step-by-step explanation:

The rule is, "multiply by six and subtract two."

So, if we add two to the number, it should be evenly divisible by 6.

We can check each number.

A. 34 + 2 = 36; 36/6 = 6. TRUE.

B. 40 + 2 = 42; 42/6 = 7. TRUE.

C. 55 + 2 = 57; 57/6 = 9½. False.

D. 88 + 2 = 90; 90/6 = 15. TRUE.

E. 119 + 2 = 121; 121/6 = 20⅙. False.

The numbers that satisfy the rule are 34, 40, and 88.

the interest earned on an account varies directly with the balance in the account. if an account with a balance of $200 earns $1

liq [111]

Answer:

$\$31.25$

Step-by-step explanation:

A relationship between two variables, x, and y, represent a proportional variation if it can be expressed in the form $y/x=k$ or $y=kx$

Let

y-------> the interest earned on an account

x------> the balance in the account

step 1

Find the constant k of proportionality

For $x=\$200,y=\$12.50$

$k=y/x$

substitute the values

$k=12.50/200=0.0625$

The equation is

$y=0.0625x$

step 2

Find the amount of interest earned on an account with a balance of $500

For $x=\$500$ substitute in the equation and solve for y

$y=0.0625(500)=\$31.25$
