𝐢𝐟 𝐲 𝐯𝐚𝐫𝐢𝐞𝐬 𝐢𝐧𝐯𝐞𝐫𝐬𝐞𝐥𝐲 𝐚𝐬 𝐱, 𝐚𝐧𝐝 𝐲=13 𝐰𝐡𝐞𝐧 𝐱=6, 𝐟𝐢𝐧𝐝 𝐲 𝐰𝐡𝐞𝐧 𝐱=8.

Question

𝐚𝐧𝐲 𝐡𝐞𝐥𝐩 𝐰𝐨𝐮𝐥𝐝 𝐛𝐞 𝐚𝐩𝐩𝐫𝐞𝐜𝐢𝐚𝐭𝐞𝐝! 𝐭𝐡𝐚𝐧𝐤 𝐲𝐨𝐮.

Answer 1

If y varies inversely as x, then the general form will be y = k/x where k is the proportionality constant.

Then, solving for k: k = xy = (6)(13) = 78 based on the information given

So, when x = 8 y = k/x = 78/8 = 9.75
