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.

What is this I am so confused please help
goblinko [34]

Answer: A

Step-by-step explanation:

When you write exponential form to radical form, the fraction tells us that kind of root it is. Since it is a cubed root, as indicated by the 3 in front of the radical, we know that the fraction will be \frac{1}{3}. If it were to be \frac{1}{3}, the entire radical would be to the power of 1. Since the radical is to the power of x, our answer would be 125^{\frac{1}{3}x }.

Question 1
----------------------------------------------------------------
a² + b² = c²
9² + 14² = c²
c² = 81 + 196
c² = 277
c= √277
c = 17cm (Rounded to the nearest whole number)

What is the equation that goes through (4,5) and is parallel to y=2x+1
forsale [732]

Answer:

The equation would be y = 2x - 3

Step-by-step explanation:

To start, we need to note that they will have the same slope, since parallel lines have the same slope. Then, we can use the point-slope form to find the equation.

y - y1 = m(x - x1)

y - 5 = 2(x - 4)

y - 5 = 2x - 8

y = 2x - 3
