A linear function h models a relationship in which the dependent variable decreases 2 units for every 3 units the independent va
ratelena [41]

Answer:

Slope=-2/3,  y-intercept=2, x-intercept=3

Step-by-step explanation:

Let the independent variable be x and dependent variable be y

y=h(x)

h is a linear function so it is represented in the general form of y=mx+c where

m is slope and c is the y-intercept.


Given "the dependent variable decreases 2 units for every 3 units the independent variable increases."

When x increases by 3, y decreases by 2

So the slope = rate of change of y / rate of change of x = -2/3


Given h(0)=2, h(0)=m(0)+c=2

c=2


Combining slope and y-intercept, y=-2/3*x+2

x-intercept is when y=0

0=-2/3*x+2

2/3*x=2

x=2*3/2=3

x-intercept=3

The product of some negative number and 4 less than twice that number is 336. Find the number.
Dennis_Churaev [7]

Let the number be 'x'

Since, the product of number and 4 less than twice that number is 336.

x \times [(2 \times x) -4] = 336

x[2x -4] = 336

2x^2 -4x- 336=0

x^2-2x-168=0

Now, we will split the middle term, we get

x^2-14x+12x-168=0

x(x-14)+12(x-14)=0

(x-14)(x+12)=0

So, (x-14)=0 or (x+12)=0

So, x = 14 or x = -12

Therefore, the negative number is '-12'.
