Answer:
y = 2/3
Step-by-step explanation:
first, you have to get y by itself. you do that by adding 2 to both sides, making the equation
3y = 2. next, you divide both sides by 3, to finish getting y by itself, making the equation y = 2/3
<span>Depending on the equation there can be three possible cases:
1- There can be 1 specific solution for the variable:
2x+4= 3
where x= -1/2
2- there can be an infinite amount of solutions:
2x+x-2=3x-3+1
where x=x
3- there can be no answer:
3+2x-x=5-3x+4x
where the solution doesn't exist</span>
The equation that best represent the actual prices of the skis is,
I x - 500 I ≥ 250
Solving the absolute value equation,
x ≤ 750 and x ≥ 250
Thus, the prices of the skis ranges from 250 to 750.
Answer:
B. 10
Step-by-step explanation:
First, we need to recognize that the two triangles are similar (the triangle with a leg value of 21 and the triangle with a leg value of 4 and hypotenuse x)
Let's first label the leg of the second triangle as y.
Then, we can set up this equation
Cross multiplying gives us
84=y^2
So, y=sqrt(84) or 2 sqrt(21).
Now, using the pythagorean theorem, we get
4^2+2sqrt(21)^2=x^2
100=x^2
x=10
I think that the answer is C.11
