Enter the value of n so the expression (-y + 5.3) + (7.2y-9) is equivalent to 6.2y + n.Please explain what and how you did it. I've seen other answers for the same question, but they do not make sense.
Answers
(- y + 5.3) + (7.2 * y - 9) = - y + 5.3 + 7.2 * y - 9 = - y + 7.2 * y + 5.3 - 9 = 6.2 * y - 3.7
6.2 * y - 3.7 = 6.2 * y + n
n = - 3.7
The correct result would be - 3.7.

performed to derive the slope-intercept form of a linear equation.
Answers
Answer:
1. You first have to find the slope
2. Next, you have to find the y-intercept
3. Finally, you have to put it in y = mx + b form.
Step-by-step explanation:
The slope of 2 points is;
The y-intercept is;
y = mx + b
m is always the slope
b is always the starting point or y-intercept
Answer:y=mx+b
Step-by-step explanation:
To summarize how to write a linear equation using the slope-interception form you
Identify the slope, m. This can be done by calculating the slope between two known points of the line using the slope formula.
Find the y-intercept. This can be done by substituting the slope and the coordinates of a point (x, y) on the line in the slope-intercept formula and then solve for b.
Once you've got both m and b you can just put them in the equation at their respective position.

2:6 becomes 1:3
Eric received $420 and we want to know what Shan got
Eric received 1 unit, therefore we multiply $420 by 3 (because 1unit x 3 = 3 units)
$420 x 3 = $1260
Shan received $1260
2/6 = 1/3
E = Eric
S = Shan
E/S = 1/3 ⇒ 3·E = S·1 ⇒ 3E = S
S = 3E
S = 3·(420)
S = 1260
Answer: $ 1260

Answer:
4 cats : 5 dogs is your answer
Step-by-step explanation:
Divide common factors from both ratios. Find the factors:
12: 1, 2, 3, 4, 6
15: 1, 3, 5, 15
The greatest common factor is 3 (as they are factors for both). Divide 3 from both numbers:
12:15
(12)/3 : (15)/3
4:5
