How do i solve this pls​
miskamm [114]
First we would solve both x’s
3x^2 - 5x
But 3 has the thingy thing (forgot the name haha)
Which means you have to multiply it by itself that many times which would be
3x3=9
So now it would be
9x- 5x = 4x
Which leaves 7 and 4x

Now you may subtract those two

7-4x= 3x

5-7k=-4(k+1)-3 add work pleasee!!!
marshall27 [118]

Answer:

k=4

Step-by-step explanation:

5-7k=-4(k+1)-3

Distribute

5-7k=-4k-4-3

Combine like terms

5-7k=-4k-7

Add 7k to each side

5-7k +7k = -4k+7k-7

5 = 3k-7

Add 7 to each side

5+7 = 3k-7+7

12 = 3k

Divide by 3

12/3 = 3k/3

4=k

. Which volume-to-surface-area ratio would be better for an ice cube— the lowest possible or the highest possible? Use the table
Oxana [17]

The volume-to-surface-area ratio would be better for an ice cube is the highest possible one.

<h3>How to explain the volume?</h3>

When you put ice into your drink, the goal is to have the ice chill your drink. This takes time. Therefore, you would want the ice to slowly melt and cool the drink for as long as you can.

You would want to have the highest possible volume to surface area ratio in an ice cube. If your ice cube is mostly surface area with less volume, it will melt quickly and water down your drink. If your ice cube has a higher ratio of volume to the surface area, it will stay solid longer and chill your drink longer.

Shannon graphed the system of equations.
ehidna [41]
All you need to do is plug -5 into the second equation and you see it is near (-5, -8). When plugged into the top, you get (-5, -27/4) which comes out to ABOUT -6.75 for the Y value. The closest is actually a tie. The first option is .8 from the first and .45 from the second leading in a total distance of 1.25. The second, which is the fellow answer, is 1.2 from the first and .05 from the second, leading to 1.25 away.

The third, which is next closest is 1.8 from the first and .55 from the second leading to a distance of over 2 from the optimal, so only the first two are answers.
