Y-intercept:8x +9y=40

Mathematics
2 answers:
Kobotan [32]3 years ago

Answer:

y-intercept or "b"= 40/9 or 4.4444

Step-by-step explanation:

To do this, we use the formula y = mx +b

m= slope

b = y intercept

The equation we are given is 8x +9y = 40.

First, we need to subtract 8x from both sides to isolate the y variable to one side:

8x +9y = 40

9y = -8x + 40

Now, we need to divide both sides by 9, to solve for "y". This will give use the format of y = mx +b.

9y = -8x +40

y = -8/9x + 40/9

Because 40/9 cannot be reduced (besides 4.44), it will be our "b" or y intercept.

y-intercept = 40/9

I hope this helps!

Amir drove from Jerusalem to the lowest place on Earth, the Dead Sea. His altitude relative to sea level (in meters) as a functi
Ierofanga [76]

The equation for the flowing rate of aamir is as follows y  =  -12x  +360

<h3>What is an 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.

First of all let's write the slope-intercept form of the equation of a line, which is:

y   =  mx  +  c

So we just need to find to solve this problem.

Moreover, this problem tells us that Amir drove from Jerusalem down to the lowest place on Earth, the Dead Sea, descending at a rate of 12 meters per minute. So this rate is the slope of the line, that is:

Negative slope because Amir is descending. So:

y    =  -   12x  +  b

To find, we need to use the information that tells us that he was at sea level after 30 minutes of driving, so this can be written as the point. Therefore, substituting this point into our equation:

y  =  -12x  +  b

0  =   -12(30)   +  b

b   =   360

Finally, the equation of Amir's altitude relative to sea level (in meters) and time (in minutes) is:

y  =  -12x  +360

Consider the sequence -2, 6, -18, 54,
hram777 [196]

Answer: The sequence is geometric

Step-by-step explanation:

In an arithmetic sequence, the consecutive terms differ by a common difference and this difference is linear.

Common difference = given term - the term before it

In geometric progression, the consecutive terms differ by a common ratio this difference is exponential.

Common ratio = given term/the term before it

Looking at the given sequence,

1) d = 6 - - 2 is not equal to - 18 - 6

Therefore, it is not an arithmetic sequence

2) r = 6/- 2 = - 18/6 = - 3

Therefore, it is a geometric sequence.
