Hello!

so, for this question you need to create a table for containers of yoghurt and their cost. what we know is that 12 containers costs 8. so in order to make our table easier you may want to divide 12 by 8 to get what is called the unit rate. this shows the cost of one container. the unit rate is 1.5 dollars per one container. now an equation for this can be 1.5x. now simply plug in the letter x for your container number and multiply. so, multiply 18 to 1.5 which gets you 27 dollars.

furthermore, to make the table, on the first column just go up by one container and plug in the container number into x for the equation 1.5x.

an example would be
1 1.5
2 3

so every time you add one to the container number, you add 1.5 to the cost!

hope this helps :) it takes practice!

Solve for x use the completing the square method x^2+6x=5

Mrac [35]

Answer:

$x_{1} =-3 +\sqrt{14} \\\\x_{2} =-3 -\sqrt{14}$

Step-by-step explanation:

$x^{2}$ +6x-5=0

we divide the coefficient of the X by half :

in this case: 6/2 = 3 , then we do the following

The result obtained is raised to square power: 3^2=9

we sum and subtract by 9 to maintain the balance of the equation:

$x^{2}$ +6x+9-9-5=0

we have:

$(x+3)^{2}$ -9-5=0

$(x+3)^{2}$ = 14

lets apply square root on both sides of the equation:

$\sqrt{(x+3)^{2}}=\sqrt{14}$

we know:

$\sqrt{a^{2}} = abs(a)$

so we have:

abs(x+3)= $\sqrt{14}$

from where two solutions are obtained

$x_{1} + 3 =\sqrt{14} \\\\x_{2} + 3 =-\sqrt{14}$

finally we have:

$x_{1} =-3 +\sqrt{14} \\\\x_{2} =-3 -\sqrt{14}$

HELP ME AND YOU'LL GET 95 POINTS ASAP

Makovka662 [10]

Answer: See explanation. Hope this helps, please consider making me Brainliest.

Step-by-step explanation:

To find the rate of change, subtract then divide. This is especially a good strategy when you have the x and y values when x = 0:

604 - 460 = 144

144 divided by 18 =

8

Therefore, the rate of change is 8. We can even go further to create an equation for this:

y intercept = 460 (because 0 multiplied by the rate of change would be 0).

slope = 8

Slope-intercept form: y = mx + b --> y = 8x + 460

Hope this helps, please consider making me Brainliest.
