100 times 7 is 700
678 times 56 is 37968
700 +8 - 37968
-37260
For this case we have that by definition, the point-slope equation of a line is given by:

Where:
m: It's the slope
b: It is the cut-off point with the y axis
We have two points:

We found the slope:

Thus, the equation is of the form:

We substitute one of the points and find "b":

Finally, the equation is:

Answer:

Answer:
x ≤ 6.12
Step-by-step explanation:
If the cost of 1 hamburger in a restaurant is $0.49, the amount of hamburger $3 can buy is expressed as shown
.
$0.49 = 1
$3 ≤ x (since you have maximum of $3 to spend. It cant be more than that)
cross multiply to find the expression for x.
$0.49 * x ≤ $3 * 1
$0.49x ≤ $3
Divide both sides by $0.49
$0.49x/$0.49 ≤ $3/$0.49
x ≤ $3/$0.49
x ≤ 6.12
The number of hamburgers you can buy is represented by the inequality x ≤ 6.12
Answer:
2(7y+19)
