Yes that would be the correct answer
I'd do this in reverse order. Mult. each of the 3 terms inside parentheses by 4:
8k^2 - 28k + 12
y=mx+b is the equation of a line;
m=slope , b= y-intercept
m=4 ; so we have : y=4x+b
We are give a set of points which it passes through, we can simply plug them in:
-2 = 4(3)+b (3 is the x and -2 is the y)
We get -2 = 12 +b .... -14=b
our final equation is : y=4x-14
Answer:
a)
<u>The equation would be:</u>
b)
Step 1. <u>Subtract 2 from both sides:</u>
Step 2. <u>Divide both sides by 3:</u>
c)
- A single box weights x= 4 units.
