Ian needs to save at least $85.00 for a new pair of basketball shoes. he has $25.00 in his piggy bank, and can save $12.00 from his allowance each week. how many weeks will ian need to save to earn at least $85.00

Lan need to save more than 5 weeks to earn at least $85.00

Step-by-step explanation:

Given :Lan has $25.00 in his piggy bank,and can save $12.00 from his allowance each week.

To Find : How many weeks will Ian need to save to earn at least $85.00

Solution :

Lan has $25.00 in his piggy bank

He can save per week = $12

Let x be the number of weeks

So, he can save in x weeks = 12x

So,. total saving in x weeks = 25+12x

Now we are given that Ian needs to save at least $85.00

So, Equation becomes :

So,  

Hence Ian need to save more than 5 weeks to earn at least $85.00 .

inverse property is the answer

step-by-step explanation:

step-by-step explanation:

to determine whether a given function is even, we simply substitute x with -x in the expression. if the result after simplification is identical to the original equation, then the function is said to be even other wise odd.

f(-x) = (-x)^2 - (-x) + 8

      = x^2 + x +8

the resulting function is not identical to the original one;

f(-x) ≠ f(x)

therefore, f(x) is not an even function
