Answer:

Slope = $\frac{1}{3}$

Step-by-step explanation:

Write the equation in y =mx + c form

3x - 9y = 4

-9y = -3x + 4

$y = \frac{-3x}{-9}+ \frac{4}{-9}\\\\y =\frac{x}{3} - \frac{4}{9}\\m = \frac{1}{3}$

Bess [88]

Answer:

The equation to describe the situation is $p-3=17.$

And, the total weight of the basket of apples was 20 pounds.

Step-by-step explanation:

The question is incomplete so, the complete question is below:

Liang bought a basket of apples to make pies for her friends. The basket of apples weighed p pounds. Before she had time to make the pies, she ate 3 pounds of apples. There are 17 pounds of apples left to make pies. Write an equation to describe this situation. What was the total weight of the basket of apples?

Now, to write an equation to describe the situation. And to find the total weight of the basket of apples.

So, the basket of apples total weighed = $p\ pounds.$

Liang ate apples weighed = 3 pounds.

And the apples left for the pies weighed = 17 pounds.

Now, to write an equation describing the situation:

$p-3=17.$

Thus, the equation is $p-3=17.$

Now, to get the total weight of the basket of apples:

$p-3=17\\\\Adding\ both\ sides\ by\ 3\ we\ get:\\\\p=20$

Hence, the basket of apples total weighed = 20 pounds.

Therefore, the equation to describe the situation is $p-3=17.$

And, the total weight of the basket of apples was 20 pounds.

Which of the following represents

stealth61 [152]

Answer:

The correct option is (c).

Step-by-step explanation:

The given number is -0.904.

We need to represent the number in scientific notation.

Any number can be written in scientific notation as follows :

$a\times 10^b$

Where

a is a real number and b is an integer

We can write it as follows :

$-0.904=-9.04\times 10^{-1}$

Hence, the correct option is (c).

Can someone please help with this ?

Answer: -9n+20

This is the same as 20-9n

================================================

Explanation:

The jump from 11 to 2 is "minus 9"

The jump from 2 to -7 is also "minus 9".

Assuming this pattern continues on, we have an arithmetic sequence with

a = 11 = first term
d = -9 = common difference

The nth term can be found like so

$a_n = a + d(n-1)\\\\a_n = 11 + (-9)(n-1)\\\\a_n = 11 -9n + 9\\\\a_n = -9n+20\\\\$

Let's check the answer by trying n = 3

$a_n = -9n+20\\\\a_3 = -9*3+20\\\\a_3 = -27+20\\\\a_3 = -7\\\\$

This shows the third term is -7, which matches what the original sequence shows. The answer is partially confirmed. I'll let you check the other values of n. You should get 11 when trying n = 1, and you should get 2 when trying n = 2.
