Answer:
52.5
Step-by-step explanation:
WX curve is 105 degrees
so to find WYX, you need to divide the WX curve by 2:
105 / 2 = 52.5 degrees
I think this is right, I have not done this in years so I am rusty at this
Assume that,
adult = x
child = y
x+2y = 35 (1st equation)
2x+3y = 60 (2nd equation)
x = 35-2y (3rd equation)
Substitute 3 into 2 :
2(35-2y) + 3y =60
70-4y +3y = 60
y = 10
x+2y = 35
x+2(10) =35
x +20 =35
x = 15
One adult = $15
Answer: I am pretty sure it is y=-1/4x-8. Hope this helps!
Step-by-step explanation:subtract the 2x from both sides which gives you 8y=-2x-64. Then you want to divide both sides by 8 to get y=-1/4x-8
The answer is c). (x-5)(x-7)

<u>Step 1: Define</u>
g(x) = x³ - 4
h(x) = x² + 2
h(-2) is x = -2
g(-1) is x = -1
<u>Step 2: Find h(-2) - g(-1)</u>
- Substitute: ((-2)² + 2) - ((-1)³ - 4)
- Exponents: (4 + 2) - (-1 - 4)
- Add/Subtract: 6 - (-5)
