Answer:
The slope should be -3.
Step-by-step explanation:

The factored form of 10xy - 15y is 5y(2x - 3)
<em><u>Solution:</u></em>
Given that, we have to write the given expression in factored form
<em><u>Given expression is:</u></em>
10xy - 15y
To find the factored form, let us first find the greatest common factor of 10 and 15
The factors of 10 are: 1, 2, 5, 10
The factors of 15 are: 1, 3, 5, 15
Then the greatest common factor is 5
Thus, factor out 5 from given expression

Now factor out the common term "y"

Thus the factored form is found
A + b = 87
a = b - 11
b - 11 + b = 87
2b - 11 = 87
2b = 87 + 11
2b = 98
b = 98/2
b = 49 <===
a = b - 11
a = 49 - 11
a = 38 <===
Answer:
33 inches
Step-by-step explanation:
The problem above shows a <em>"direct proportion,"</em> which means that when one quantity increases <em>(days)</em>, the other quantity increases<em> (inches of rain).</em>
Step 1: Represent the amount of rain by n.
Step 2: Setup a proportion.
=
(where 14 refers to the number of days in 2 weeks)
Step 3: Cross multiply:
15 x 31 = 14n
465 = 14n
Step 4: Find n by dividing both sides by 14.
n = 33.21
Step 5: Round off to the nearest inch.
n = 33 inches
