1. order pairs : (3,1), (-2,-1)

1 + 1 / 3 + 2 = 2 / 5 is the slope

2. order pairs : (2,-3), (-3,2)

-3 - 2 / 2 + 3 = - 5 / 2 is the slope

3. order pairs : (1,3), (-1,-2)

3 + 2 / 1 + 1 = 5 / 2 is the slope

I used the slope formula to get my answers.

Answer:

k = 0.2645

Step-by-step explanation:

Given model:

y = 4070 $e^{kt}$

y = no. of hits website received = 9000 (in 3rd month)

t= no. of months website has been operational = 3

put in the above equation:

9000 = 4070 $e^{3k}$

$\frac{9000}{4070}$ = $e^{3k}$

$\frac{900}{407}$ = $e^{3k}$

Taking natural logarithm on both sides, we get:

$ln\frac{900}{407}$ = $ln(e^{3k})$

$ln\frac{900}{407}$ = 3k lne

lne=1

$ln \frac{900}{407}$ = 3k

or k = $\frac{1}{3}$ $ln\frac{900}{(407)}$

k = $\frac{1}{3}$ (0.7936)

k = 0.2645

Nezzie is shopping for items for her daycare because the store is having a sale where everything in the store is 10% off. Nezzie

Harman [31]

Soo 100.26-15% off = $85.25 and 59.99 you need to crank it up 1 so $60-10% off=$54 last add $85.25+$54=$129.25

So no she is not right

Can someone solve this? and tell me how?

maksim [4K]

Answer:

1/3

Step-by-step explanation:

When working with balanced expressions (stuff on both sides of the equal sign), "what you do to one side, you do to the other", which keeps it balanced.

The first thing we notice is the exponent 1/4, which is one both sides, so we can get rid of it on both sides by using the reverse operation.

The reverse of exponents is square root.

$(4x + 10)^{\frac{1}{4}} = (9 + 7x)^{\frac{1}{4}}\\\sqrt[\frac{1}{4}]{(4x + 10)^{\frac{1}{4}}} = \sqrt[\frac{1}{4}]{(9 + 7x)^{\frac{1}{4}}}\\\\4x + 10 = 9 + 7x$
