The final cost of a sale item is determined by multiplying the price on the tag by 75%. Which best describes the function that r

epresents the situation?
It is linear because the ratio of the change in the final cost compared to the rate of change in the price tag is constant.
It is linear because the function is continuous.
It is nonlinear because the final cost is determined by multiplying each price tag by 0.75.
It is nonlinear because the price tag and final cost columns do not have the same common difference

and with that template in mind,

notice from a parent function of   f(x) = x³,
a derived function with f(x+5) = (x + 5)³

has a C component of 5, C = 5, which means is the as the parent, just shifted to the left by 5 units.

Can you simplify 2 over 7
zmey [24]

Answer: No!

Step-by-step explanation:

2 is a prime number

7 is a prime number

They both are prime numbers so they cant be simplified further. They both are already simplified to the lowest terms.

Hope this helps :)

Write an equation of the line parallel to 3x + 5 = 2y that has a y-intercept of -1
denpristay [2]

Answer:

3x - 2 = 2y

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

Rearrange 3x + 5 = 2y into this form by dividing all terms by 2

\frac{3}{2} x + \frac{5}{2} = y ← in slope- intercept form

with slope m = \frac{3}{2}

Parallel lines have equal slopes and c = - 1, thus

y = \frac{3}{2} x - 1 ← in slope- intercept form

Multiply through by 2

2y = 3x - 2 ← equation of line
