11. 1. Which of the following equations defines a joint variation?A, y=kxB.y =k/xC.z= kxyD. Z=kx/y
Answer:
C
Step-by-step explanation:
Joint variation describes a situation where one variable depends on two (or more) other variables, and varies directly as each of them when the others are held constant. We say z varies jointly as x and y if. z=kxy. for some constant k.
12. the equalation is a, y=kx is called?
________________________________
ANSWER:"CONSTANT"
y=kx. for some constant k , called the CONSTANT of variation or constant of proportionality . (Some textbooks describe direct variation by saying " y varies directly as x ", " y varies proportionally as x ", or " y is directly proportional to x .

16. Find the equal roots of this quadratic equation: 2x^2-kx+5=0[tex]2x {}^{2} - kx + 5 = 0[/tex]
Answer:
Step-by-step explanation:
[tex]b^{2} -4ac=0[/tex]
a=2 b=-k c=5
[tex](-k)^{2} -4(2)(5)=0[/tex]
[tex]k^{2} -40=0[/tex]
[tex]k^{2} =40[/tex]
[tex]\sqrt{k^{2} } =\sqrt{40}[/tex]
[tex]k=2\sqrt{10}[/tex]
[tex]k=-2\sqrt{10}[/tex]
Substitute value of k to the equation:
[tex]2x^{2} -kx+5=0[/tex]
[tex]2x^{2} -2\sqrt{10}x+5=0[/tex]
[tex]2x^{2} +2\sqrt{10}x+5=0[/tex]

18. the mathematical phrase for y=kx is
Answer:
direct variation
Step-by-step explanation:
Direct variation describes a simple relationship between two variables.
Answer:
Two sets of values have direct variation, or directly proportional if y = kx, where k is the constant of variation.
This means that whatever you do to the x, the same applies to the y. So, for example, if you double the x, you also double the y as well.
Hope it helps!

23. kx²-49=(2x+7)(2x-7)4y²-kx²=(2y+3x)(2y-3x)what is the value of k?
Answer:
1. k = 4
2. k = 9
Step-by-step explanation:
kx²-49=(2x+7)(2x-7)
Let's solve for k.
kx² − 49 = (2x+7)(2x−7)
Step 1: Add 49 to both sides.
kx² − 49 + 49 = 4x² − 49 + 49
kx² = 4x²
Step 2: Divide both sides by x^2.
[tex]\frac{kx^{2} }{x^{2} } = \frac{4x^{2} }{x^{2} }[/tex]
ANSWER:
k = 4
----------------------------------------------------------------------------------------------------
4y²-kx²=(2y+3x)(2y-3x)
Step 1: Add -4y^2 to both sides.
−kx² + 4y² + −4y² = −9x² + 4y² + (−4y²)
−kx² = −9x²
Step 2: Divide both sides by -x^2.
[tex]\frac{-kx^{2} }{-x^{2} } = \frac{-9x^{2} }{-x^{2} }[/tex]

k = 9

a
Step-by-step explanation:
because that is direct variation
25. in direct variation equation y= kx=
Answer:
y = kx. In this case, you should use c and d instead of x and y and notice how the word “square root” changes the equation. Step 2: Use the information given in the problem to find the value of k. In this case, you need to find k when c = 6 and d = 256.

29. which is an example of an inverse variation?a. xy=10 b. y=k/x c. y=kx d. h=kx
Answer:
B.
Step-by-step explanation:
Inverse variation is always in the form of y= k/x
which in text is " the number y is inversely proportional to the number x". Don't worry about the k, it is usually constant.
30. direct Variation can be illustrated by the question_____.A. y=kxB. k=xyC. y=1/kxD. x=1/ky
