7 0

Use distributed property first
6*7x= 42x
6*9= 54
42x-54

add it to the equation

42x-54+15

combine like terms

-54+15 = -39

42x-39 is your answer

Are the graphs of the lines in the pair parallel? Explain. y=2\3x-17 4x-6y=-7

Papessa [141]

<span>y=2\3x-17and 4x-6y=-7 implies - 6y= - 4x -7, and then y= (-4/-6)x +7/6 and so
y=2/3x+7/6

but when we have y=ax+b and y=a'x+b', the two lines are parallels if a=a', in our case 2/3=2/3 the lines are parallel

Answer:

Step-by-step explanation:

The probability of obtaining a 3 is

P(3) = $\frac{1}{6}$

Then after 30 spins the predicted number of times it should land on 3 is

30 × $\frac{1}{6}$ = 5

A machine needs 2 of its gears replaced. You find 2 gears, one manufactured 5 years ago and the other manufactured 10 years ago.

Tcecarenko [31]

Probability that gear 1 will fail = 5/100 (upto 10 years)
and 8/100 (after 10 years)

Probability that both will fail = 5/100 * 8/100
= 40/10000
= 0.4 %

Dana Thacker's bank granted her single payment loan of 10,450 she agreed to repay the loan in 75 days at an exact interest rate

il63 [147K]

Using simple interest, it is found that the maturity value of the loan is of 10,638.

<h3>Simple Interest</h3>

The amount of money after <em>t years </em>in simple interest is modeled by:

$A(t) = A(0)(1 + rt)$

In which:

A(0) is the initial amount.

r is the interest rate, as a decimal.

In this problem:

A loan of 10450 is taken, hence $A(0) = 10450$ .

Interest rate of 8.25%, hence $r = 0.0825$

The loan will be repaid in 75 days, considering the time in years, $t = \frac{75}{365}$

Then, the maturity value of the loan is:

$A(t) = A(0)(1 + rt)$

$A\left(\frac{75}{365}\right) = 10450\left[1 + 0.0875\frac{75}{365}\right] = 10638$

The maturity value of the loan is of 10,638.
