Determine whether the value ๐ฅ=4 makes the following equations true or false.True False ๐ฅ+48โ1=06+๐ฅ=25โ๐ฅ2=โ113(7โ๐ฅ)+8=16
Question
Solution
Sure, let's solve these equations one by one:
-
๐ฅ+48โ1=0 Substitute ๐ฅ=4 into the equation: 4+48-1=0, which simplifies to 51=0. This is false.
-
6+๐ฅ=2 Substitute ๐ฅ=4 into the equation: 6+4=2, which simplifies to 10=2. This is false.
-
5โ๐ฅ^2=โ11 Substitute ๐ฅ=4 into the equation: 5-4^2=-11, which simplifies to 5-16=-11. This simplifies further to -11=-11. This is true.
-
3(7โ๐ฅ)+8=16 Substitute ๐ฅ=4 into the equation: 3(7-4)+8=16, which simplifies to 3*3+8=16. This simplifies further to 9+8=16, and finally to 17=16. This is false.
So, the value ๐ฅ=4 makes the third equation true, and the rest false.
