The slope intercept form is:
Where is the slope of the line and the intercept with the y-axis.
To find the slope, take any two points from the table provided. For example:
(1, 1/5)
(3, 1)
So:
Now we find b substituting any point of the table in the equation:
We substitute the poiunt (3, 1) for example:
Now we solve for b:
Finally, the equation is:
The answer is the last option
Part 1) <span>Each sandwich costs $.02 per cubic inch to make. What is the cost of each sandwich?
</span>volume for cube sandwich is 125 in³
volume for pyramid sandwich is 41.67 in³
cost of each cube sandwich=0.02*125-----> $2.5
cost of each pyramid sandwich=0.02*41.67-----> $0.83
the answers Part 1) are
a) cost of each cube sandwich is $2.5
b) cost of each pyramid sandwich is $0.83
Part 2) <span>If each sandwich sells for $4.00 and Mr. Sammie sells 100 Cube sandwiches and 100 Pyramid Sandwiches, how much profit would Mr. Sammie make?
</span>
we know that
Profit=Sells-Costs
step 1
find the sells
Sells=200*$4-----> $800
step 2
find the costs
Costs=100*$2.5+100*$0.83----> $333
step 3
find the profit
Profit=Sells-Costs
Profit=$800-$333-----> $467
the answer Part 2) is
the profit is $467
So we need to factor it into (ax+b)(cx+d)
since we have 1x^2, a and c=1
so factor into (x+b)(x+d)
if we expand, we get
so we need 2 numbers that add to get the middle number and multiply to get the last number
I would factor the last number and see which ones add to the middle one
what 2 numbers multily to get 72 and add to get 17?
hmm, list factor of 72 and add them
1+72=73, nope
2+36=38, nope
3+24=27, nope
4+13=17, yep
so it facotrs to (x+4)(x+13)
You just have to multiple it and what you get is 224
