Answer: b.
Step-by-step explanation:
Based on the information given, you can write the following expression:
Where k is the the constant of variation
If y=4/63 when x=3, then you can substitute these values into the expression and solve for k:
Substitute k into the expression. Then the equation is:
Substitute x=5 into the equation. Then, y is:
Answer:
Final cost of ticket = $205
Step-by-step explanation:
Speed limit is given: 60 miles per hour
Car travelling at a speed of: 78 miles per hour
Car is exceeding speed limit by: 78 - 60 = 18 miles per hour
We are given that the dine ticket includes $25 plus $10 for each mile over the speed limit:
Final cost of ticket = $25 + (miles over speed limit * 10)
= 25 + (18*10)
= 25 + 180 = $205
Answer:
a = -15.5, b = -32.5
Step-by-step explanation:
Let's say the first number is a, and the second is b.
a + b = - 48
a - b = 17
If you add both equations, you get 2a = -31, because the
+b and -b cancel each other.
So you would get a + a = 2a, then -48 + 17 = -31
2a = -31
--- ---
2 2
Divide both sides by 2 to get a by itself.
a = -15.5
Then let's go to the next equation (a - b = 17)
Plug in a..
-15.5 - b = 17
+ 15.5 + 15.5
------
-b = 32.5
--- ------
-1 -1
b = -32.5
Hope this helps.
Answer: –4rx –15x^2 + 8r + 26x
Step by step:
= 2x + −15x^2 + 24x + −4rx +8r
= (−4rx) + (–15x^2) + (8r) + (2x+ 24x)
= –4rx + –15x^2 + 8r + 26x
