The answer is a.
When you are solving problems like this you would use the equation y^2=4ax. The x and Y would be the coordinates. Based on the equation you have given the coordinates would be (6,12) and (6,-12), (24 is split up evenly between the y-axis).
Then we go on to solve the equation by plugging in the numbers 12^2=4a(6)
144=24a
144/24=24a/24
6=a
Solve for hypotenuse
Hypotenuse =
![\sqrt{a^{2}+b^{2}}](https://tex.z-dn.net/?f=%20%5Csqrt%7Ba%5E%7B2%7D%2Bb%5E%7B2%7D%7D%20)
Substitute 3 for A and 4 for B
![\sqrt{3^{2}+4^{2}}](https://tex.z-dn.net/?f=%20%5Csqrt%7B3%5E%7B2%7D%2B4%5E%7B2%7D%7D%20)
Solve exponents
3^2 = 9
4^2 = 16
![\sqrt{9+16}](https://tex.z-dn.net/?f=%20%5Csqrt%7B9%2B16%7D%20)
Add
9 + 16 = 25
![\sqrt{25}](https://tex.z-dn.net/?f=%20%5Csqrt%7B25%7D)
Solve square root
![\sqrt{25}](https://tex.z-dn.net/?f=%20%5Csqrt%7B25%7D)
= 5
5 is your answer
Answer:
$7.74
Step-by-step explanation:
0.75x46=34.5
0.52x63=32.76
34.5+32.76=67.26
75-67.26=7.74
Answer:
67796.61
Step-by-step explanation:
Multiply the first equation by -2 gives:_
-2y = -8 + 2x
2y = 8 - 2x
adding these 2 equations:-
0 = 0
This shows that the 2 equations are equal so there are infinite solutions
