80/16=5 since they were $3 off the regular price is 8

First divide 80 by 16: 80/16=5

Since they say the original price was $3 more than when the sale came you have to do 5+3=8

$8 is the original price of each hinge

If (-1, y) lies on the graph of y=2^2x then y=

zubka84 [21]

Answer:

y is 1/4 when x is -1 if I did interpret your equation right. Please see that I did.

I believe the equation to be $y=2^{2x}$ . If you meant $y=2^2x$ , please let me know.

Thanks kindly.

Step-by-step explanation:

If (-1,y) lies on the graph of $y=2^{2x}$ , then by substitution we have:

$y=2^{2\cdot -1}$ .

We just need to simplify to determine y:

$y=2^{2 \cdot -1}$

Multiply the 2 and -1:

$y=2^{-2}$

Use reciprocal rule for exponents to get rid of the negative:

$y=\frac{1}{2^2}$

$2^2$ just means $2(2)$ :

$y=\frac{1}{2(2)}$

$y=\frac{1}{4}$ .

<h3>Linear equation</h3>

A linear equation is in the form:

y = mx + b

where y, x are variables, m is the slope of the line and m is the y intercept.

Let y represent the total cost of hiring for x hours. Hence:

Using the points (0, 125) and (15, 950)

$Slope = \frac{y_2-y_1}{x_2-x_1} =\frac{950-125}{15-0} =55$

The rate of change is $55 per hour. The means that the hourly rate of the designer is $55 per hour
