He amount of money left in alma’s bank account is expressed by the linear equation y = -27x + 577, where x represents the number of weeks and y represents the amount of money left in her account. after how many weeks will alma have $145 left in her account?

After 16 weeks she will have 145 dollars left in her account.

Step-by-step explanation:

since 145 represents the amount of money in her account we will substitute that for "y" and solve for "x"

145=-27x+577

145-577=-27x

-432=-27x

-432/-27= -27x/-27

16=x

hello from mrbilldoesmath!

answer:

the domain is the set { -2, 0, 2, 3}

discussion:

the domain is the set of x values in the ordered pairs (x,y). taking the x, or first component, of each ordered pair gives   -2, 0, 2, 3.
