Equation is y=kx.  We have four chance to figure out k; hopefully they all give the same result

x=9, y=63,  y=kx becomes 63=k(9) so k=63/9=7

x=4, y=28, 28=k(4), k=7

The constant of proportionality is 7; we check  2×7=14, 11×7=77

Answer: k=7,   y=7x

Answer:

y=kx

y=k(7)x

y=7x(11)

y=7*11

y=77

Step-by-step explanation:

So with useing the equation that I used the porportional relationship is 7 so just fill 7 in for k. Then take the x number and fill it in for x. you will then multiply and get the y value.

Since the first equation says y= x-4, substitution that for the y value in x + y = 6

x + x - 4 = 6

add up the x’s to get 2x - 4 = 6

add 4 to both sides to get 2x = 10

divide both sides by 2 to get x = 5

the x value is 5

then, to figure out the y value, substitute 5 for the x value in y = 5-4

the y value is 1

final answer: x = 5 and y = 1

hope this helped!!

The line with equation a + 4b = 0 coincides with the terminal side of an angle θ in standard position and cos θ > 0. What is
ankoles [38]

Answer:

Option A. -(\frac{\sqrt{17}}{17})

Step-by-step explanation:

Equation of a given line is a + 4b = 0 or b = -\frac{1}{4}a

This in the form of y = mx + b, which is slope-intercept form.

Here slope of the line is (-\frac{1}{4}).

Or tanθ = \frac{(-1)}{4}

This line coincides with the terminal side of the angle in standard position where cosθ > 0

Since tanθ = \frac{\text{Height}}{\text{Base}}

and sinθ = \frac{\text{height}}{\txt{Hypotenuse}}

Hypotenuse = \sqrt{\text{height}^{2}+\text{Base}^{2}}

                     = \sqrt{(1^{2}+4^{2})}

                     = \sqrt{17}

Since tanθ is negative and cosθ > 0 that means θ lie in fourth quadrant.

Therefore, sinθ will be negative.

[ \frac{-sin\theta}{+cos\theta}=-tan\theta ]

sinθ = -\frac{1}{\sqrt{17}}

       = -\frac{1}{\sqrt{17}}\times \frac{\sqrt{17} }{\sqrt{17}} = -\frac{\sqrt{17}}{17}

Answer will be option A.
