Answer:
B. 12
Step-by-step explanation:
First, we need the degrees for <em>A</em>. So, cos<em>x </em>= 5/13 = 67.4
Now it will be easy to solve a. tan67.4° = a/5 = 12.011728511....
we round it to the nearest tenth and we get 12.
The correct answer is: [D]: "The relationship is NOT linear."

Answer:
Step-by-step explanation:
12(5+2y)=4y-(6-9y)
Distribute
12*5 +12*2y = 4y - 6 +9y
60 +24y = 4y - 6 +9y
Combine like terms
60+24y =13y -6
Subtract 13 y from each side
60 +24y-13y=13y-13y -6
60+11y = -6
Subtract 60 from each side
60+11y-60 =-6 -60
11y = -66
Divide by 11
11y/11 = -66/11
y =-6
Check
12(5+2(-6))=4(-6)-(6-9(-6) )
12 (5-12) = -24 - (6+54)
12(-7) = -24 -60
-84 = -84
True so the solution is correct
Answer:
That point would now be half as close to the origin, so (2,-1).
Answer:
Step-by-step explanation:
so first you need to make a equation
since we are trying to find out the amount of rides we can make that stand for x so..
we can first write it as 2.50x
(x = the numbers of rides)
since the entree fee is 17 dollars but they are two kids we have to times 17 by 2 giving us 34 we can add 34 dollars to the equation
34 + 2.50x
alex and kendra have only $51.50 dollars and they cant spend more then that so that means the whole equation has to equal $51.50
34 + 2.50x = 51.50
since we are trying to find the number of rides we can subtract 34 on both sides giving us
2.50x = 51.50 - 34
2.50x = 17.50
then we solve for x which you can divde 2.50 on both sides
x = 17.50 /2.50
x = 7
