     9y - 5x = 20
or, (9y - 5x) / 20 = 1
or, 9/20 y - 1/4 x = 1
compare with x/a + y/b = 1
you'll get
x intercept (a) = -4
y intercept (b) = 20/9

I have the answer, I just need to explain how I got it. Please help!

Answer:

<h2>Table 2 is correct, you have it wrong</h2>

Step-by-step explanation:

The way we determine if ratios are equivalent is by a proportion. It also helps to know that a foot is 12 inches, so you have the wrong answer. The correct answer is table 2. The way we solve is by dividing the number of inches by 12 to see if we get the number of feet specified on the table.

24/12 = 2

60/12 = 5

72/12 = 6

84/12 = 7

All of these match up to their respective foot measurements.

konstantin123 [22]

Answer:

128500

Step-by-step explanation:

This is an arithmetic sequence with a common difference of 3500

The formula for an arithmetic sequence is

an = a1+d(n-1)  where a1 is the first term and d is the common difference

an = 48000+ 3500(n-1)

We want n = 24

a24 = 48000+3500(24-1)

       = 48000+3500(23)

       =48000+80500

       =128500

Am I correct??????????
vekshin1
Yes,you got the correct answer!

To prove x≥-32:

\frac{x}{4}   \geqslant   - 8 \\ x  \geqslant   - 8 \times 4   \\  x  \geqslant - 32
Therefore x≥32.

Hope it helps!
