What is the inverse of the function y-2 = 7x?

Sydney rolls a ball 63 inches across the floor. This is 7 times the distance that Brendan rolls his ball across the floor. Let n

9 inches across the floor Brendan rolls his ball if Sydney rolls a ball 63 inches across the floor.

<h3>What is linear equation?</h3>

It is defined as the relation between two variables, if we plot the graph of the linear equation we will get a straight line.

If in the linear equation, one variable is present, then the equation is known as the linear equation in one variable.

We have:

Sydney rolls a ball 63 inches across the floor. This is 7 times the distance that Brendan rolls his ball across the floor.

Sydney rolls = 7n

Here n represent the number of inches Brendan rolls his ball.

63 = 7n

n = 63/7 = 9 inches

Thus, 9 inches across the floor Brendan rolls his ball if Sydney rolls a ball 63 inches across the floor.

Hellen used a coupon she received in the mail at a local boutique that decreased her purchase of $85.20 by $12.78. Her sister us

Over [174]

Answer:

y = 12665 (100⁻¹) + b

Step-by-step explanation:

To model this relationship, you're to write the equation of a line; in the form

y = mx + b

Now let y represent the full coupon value,

mx represent the amount spent by Hellen and her sister

and b, the change that's left on the coupon.

So, the summary of Hellen's transaction is:

$85.2 became $(85.2 - 12.78) which is = $72.42

The summary of her sister's transaction is:

$63.8 became $(63.8 - 9.57) which is = $54.23

So y - (72.42 + 54.23) = b

y - 126.65 = b

y = 126.65 + b

Separating m from x in mx, you have

y = 12665 x 1/100 + b

y = 12665 (100⁻¹) + b

Where m = 12,665 and x = 100⁻¹

In a certain four-engine vintage aircraft, now quite unreliable, each engine has a 15% chance of failure on any flight, as

Romashka [77]

Answer:

0.0975 or 9.75%

Step-by-step explanation:

Assuming that no engines fail simultaneously, the probability that exactly one engine fails is the probability that the first engine fails (15%) multiplied by the probability that the second engine does not fail (100% - 35%):

$P = 0.15*(1-0.35)\\P=0.0975$

The probability of exactly one engine failure is 0.0975 or 9.75%

Korvikt [17]

We have an equation: ?/140= 15/100

Cross multiply:
100*?= 15*140
⇒ ?= 15*140/100= 21
