Answer:
figure skates will be $1 cheaper.
Explanation:
<u>given equation</u>:
- to rent figure skates : f(x) = 1.50x + 2
- to rent hockey skates : h(x) = 2x +1.5
<u>solve for rent of figure skates</u>:
f(x) = 1.50x + 2.00
f(3) = 1.50(3) + 2.00
f(3) = 6.5
<u>solve for rent of hockey skates</u>:
h(x) = 2x + 1.5
h(3) = 2(3) +1.5
h(3) = 7.5
<u>cheaper - figure skates than hockey skates</u>:
$7.5 - $6.5
$1

The Correct choices are :
- the dependent variable is y
- the rate of change is not constant
- independent variable is x
- This is a negative relationship
- The relationship is nonlinear
Answer:
The number of kids NOT wearing socks in the gym = 20
Step-by-step explanation:
Here, the total number of kids in the gym = 80
Now, 75% of the kids are wearing socks.
Let us assume the number of kids wearing socks = m
⇒ 75 % of 80 = m
Calculating the value of m ,we get:

⇒ 60 kids are wearing socks.
Kids not wearing socks = Total kids in gym - Kids wearing socks
= 80 - 60 = 20
Hence, the number of kids NOT wearing socks in the gym = 60.
Answer:
Adnan is incorrect because cosx and sin(90 - x) are always equivalent in any right triangle ⇒ first answer
Step-by-step explanation:
In any right triangle there are two acute angles sum of them is 90°
∴ If one of them x°, then the other is (90 - x)°
∵ cos x = adjacent/hypotenuse
∵ sin(90 - x) = opposite/hypotenuse
∵ The opposite of ∠(90 - x) is the adjacent of ∠x
∴ cosx = sin(90 - x)
To solve this, just add like terms. 3y+2y=5y; -5x+-3x=-8x. So, the answer is -8x+5y or 5y-8x.
