Answer: 25
Step-by-step explanation:
There are two variables which is u and v and is given that u is 3 and v is 7 so input that into the expression and solve.
2(3)^2 + 7 Solve the exponent first
2(9) + 7 Now multiply then add
18 + 7 = 25
3.5 miles per hour. 7/8 (.875) divided by 1/4 (.25) equals 3.5. Hope this helps!
Answer:
Step-by-step explanation:
a) the points (0,60) and (6.0) are the intercept points for the graph of the car slowing down ( accelerating in the opposite direction than it's traveling)
we already know the slope of the line b/c that the rate at which it's slowing .. -10 =m which is the slope of the line .. down 10
use the point-slope formula y-y1 = m(x-x1) and plug in either given point for (x1,y1)
b) y -60 = -10(x-0)
y= -10x+60
thats the slope-intercept form of the equation
Answer:
$92
Step-by-step explanation:
Since Sally plans to keep the kayak for 6 hours and it's $7 per hour we can multiply 6*7 to determine how much she will be charged for keeping the kayak.
6*7=$42
Now we add this to the original deposit of $50.
$50+$42=$92
