Drag and drop the constant of proportionality into the box to match the table. If the table is not proportional, drag and drop "

podryga [215]

Option B: 3 is the right answer

Step-by-step explanation:

If y varies directly as x, it can be expressed as:

y ∝ x

$y= kx$

If the values in table are directly proportional then the value of k should be same for all pairs.

$k = \frac{y}{x}\\k = \frac{6}{2} = \frac{9}{3} = \frac{12}{4} = \frac{15}{5} = 3$

the table is directly proportional and the value of k is 3

Hence,

Option B: 3 is the right answer

What is the solution set of the equation 8x+2=x+4x−6 ?

lara31 [8.8K]

$8x+2=x+4x-6\\\\8x+2=(x+4x)-6\\\\8x+2=5x-6\qquad\text{subtract 2 from both sides}\\\\8x=5x-8\qquad\text{subtract 5x from both sides}\\\\3x=-8\qquad\text{divide both sides by 3}\\\\\boxed{x=-\dfrac{8}{3}}$

write an equation in slope-intercept form for the line that has a slope of 4 and passes through the point (3,24)

Harman [31]

Answer:

y = 4x + 12

Step-by-step explanation:

y = mx + b

'm' represents slope

'b' represents the y-intercept

use the slope and the point (3,24) as your x and y inputs to find 'b'

24 = 4(3) + b

24 = 12 + b

b = 12

y = 4x + 12
