Answer:
Answer is+28
Step-by-step explanation:
To solve this question,we will have to do the normal calculation first by opening the bracket then it's followed by substitution
Ok...let's start solving
Back to the question,
-2(3x-2)+x+9
Using bodmas rule
Bracket first,
-6x+4+x+9
Collect like terms
-6x+x+4+9
-5x+13
And in the question,it states that x=-3
Therefore we will have to substitute the value of x into our initial answer
-5(-3)+13
Remember that -×-=+
+15+13
=+28
So you can take 4/5 and make it easier by turning it into a decimal
If you do that you need to multiple so the Denominator is 10 so 4 times 2 and 5 times 2 so 8 divided by 6 or 8/6 is 1.3 Repeating
Answer: 1.3 Repeating
So the equation of a line is:
y = mx + b
You are given an x and a y and a rate, which is the slope of the line (m).
The rate is given as N per unit. This means the 'unit' whatever it is referring to will be your 'x' variable.
Then solve for y-intercept (b) by subbing in your x,y values.
----> b = y - mx
Example 3:
Rate is $8 per day. Days are my x variable, Dollars are my y variable.
Given: x = 3, y = 29
b = y - mx = 29 - (8)(3) = 29 - 24 = 5
Equation of line:
y = 8x + 5
Hope this helps
First you have to find out how much he is making off of that one pack. To do that, you must multiply the number of dollars for each bottle, by the number of bottles.
24 x $1.50 = $36
After you do that, you have to subtract the initial cost by the money earned.
$36 - $4 = $32
Mr. Lillie will make $32 in profit
