Mr. and mrs. jefferson have a total of $5170 in a bank. at the end of the month, mr. jefferson deposit $450 into his account and mrs. jefferson deposit $626 into her account they now have an equal amount of money in their accounts. how much money did each of them have at first?
many students gets confused with these exponential problems, they often get misguided but understand that there is nothing to be confused of.
when you have a negative number, you just take the reciprocal of the whole exponent number.
what is a reciprocal?
let's take an integer for example, let's take the number 3.
the reciprocal for 3 is (1/3)
let's take an other number, let's take 2/3
the reciprocal for 2/3 is (3/2)
in conclusion, we just reverse the denominator and the numerator or just switch it.
we take 3 as (3/1) and that is the reason, the reciprocal would be (1/3)
now, coming to the negative integers. taking an example:
this would be become (1/2¹) = (1/2)
hence, the result of a negative integer is positive but would be a fraction.

choice a is correct answer.
y= mx+c is slope-intercept form for equation of line where m denotes slope and c denotes y-intercept.
slope is ratio of change in y to change in x.
slope= m = δy/δx
y-intercept is a point on graph where the value of x is zero.
given equation is :
y = 1/5x-6
hence,slope = m= 1/5 and y-intercept = c = -6
hence, choice a is your answer.
answer: you still need 52% which would be .52 if you want it in decimal form
