Answer:

$x=-\frac{83}{7}$

Step-by-step explanation:

use distributive property:

$10x+80=3x-3$

you have to move all the terms with $x$ to the left side of the equation:

subtract 3x from both sides

$10x+80-3x=-3$

combine like terms

$7x+80=-3$

subtract 80 from both sides

$7x=-3-80$

$7x=-83$

divide each term by 7

$\frac{7x}{7} =\frac{-83}{7}$

$x=-\frac{83}{7}$

Which expression can be used to approximate the expression below,for all positive number a,b and x where a =/ 1 and b=/ 1

rodikova [14]

Answer:

The correct option is 1.

Step-by-step explanation:

The given expression is

$log_ax$

The value of a is 1 and the value of b is 1.

According to the logarithm property,

$log_mn=\frac{log_pm}{log_pn}$

Using this property, we get

$log_ax=\frac{log_bx}{log_ba}$

The required expression is $\frac{log_bx}{log_ba}$ .

$log_1x=\frac{log_1x}{log_11}$

$log_1x=log_1x$ $[\because log_aa=1]$

Left hand side is equal to the right hand sides, therefore option 1 is correct.

A snack bar at an outdoor fair is open from 10 A.M. To 5:30 P.M. And has 468 bottles of water for sale. Sales average 1.3 bottl

ch4aika [34]

Answer:

the question is incomplete, so I looked for similar ones

the number of bottles of water remaining as a function of time:

f(x) = -78x + 468

1.3 bottles are sold per minute x 60 minutes per hour = 78 bottles per hour

x = number of hours

the slope is -78

the y intercept is 468

domain = 0 ≤ x ≤ 7.5 hours (from 10 AM to 5:30 PM)

range = 0 ≤ y ≤ 468 bottles

the snack will run out of bottles of water by 4 PM

78x = 468

x = 468 / 78 = 6 hours

if the snack wants to have enough bottles of water to serve all its customers, it will need:

78 x 7.5 hours = 585 bottles of water
