Answer:

The stores at no point in time will charge same rate ( their rates will always be different)

Step-by-step explanation:

To get the value of x that they charge same rate, we simply equate the value of rate in both;

thus;

8x-5 = 2(4x + 6)

8x-5 = 8x + 12

From what we have here, we can conclude that the equation has no solution

Write the equation of a line in slope intercept form that has a slope of 1/5 and contains (-10,6)
VLD [36.1K]

Answer:

y = \frac{1}{5} x + 8

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 )

here m = \frac{1}{5}, hence

y = \frac{1}{5} x + c ← is the partial equation

To find c substitute (- 10, 6) into the partial equation

6 = - 2 + c ⇒ c = 6 + 2 = 8

y = \frac{1}{5} x + 8

In New York State, the minimum wage has grownexponentially. In 1966, the minimum wage was$1.25 an hour and in 2015, it was $8.75
Alona [7]

The Solution.

In 1966, which is the initial year(t); t = 0, and minimum wage(y), y = $1.25

Similarly.

In 2015, t = 49 years , (that is, 1966 to 2015), and y = $8.75

The rate of growth to the nearest percent is

\text{Rate of growth =}\frac{y_2-y_1}{t_2-t_1}\times100\begin{gathered} \text{Where y}_2=8.75,t_2=49\text{ years} \\ y_1=\text{ \$1.25},t_1=0 \end{gathered}

Substituting into the formula above, we get

\text{Rate of growth =}\frac{8.75-1.25}{49-0}\times100\text{Rate of growth = }\frac{7.5}{49}\times100=15.31\approx15\text{ \%}

Hence, the correct answer is 15%
