Answer:
-3
Step-by-step explanation:
An increase in x-value from 9 to 10 is an increase of 1 unit. The slope of -7 tells you that the corresponding change in y will by -7 units:
v = 4 -7 = -3
The value of v is -3.
_____
<em>Alternate solutions</em>
You can see this easily on a graph, or you can use the equation of the line. We have a point and a slope, so the point-slope form is useful.
y = m(x -h) +k
y = -7(x -9) +4
For x=10, the value of y is ...
v = -7(10 -9) +4 = -7 +4
v = -3
Answer:
16%
Step-by-step explanation:
16 + 84 is equal to 100 students in total. 16 students (the number of students that are taking health) / 100 students (the total student body) equals .16, or 16%.

Answer:
The normal price of the drink is $1.2
Step-by-step explanation:
We are given the following in the question:
Number of drinks bought = 22
Discount on each drink = $0.35
Total money paid = $18.70
Let x be the normal price of the drink.
Thus, we can write the equation:
Thus, the normal price of the drink is $1.2
