Wally opened a savings account with a deposit of $100. He plans
to put $40 each week into the account. What is the equation of the
line in slope-intercept form that shows Wally's total savings?

y=40x+100

Step-by-step explanation: it’s growing by 40 every week so x=number of weeks and 100 is the starting point so you always add that. Ex) week 3: 40(3)+100 = 120+100=220

which expression represents the approximate length of bc?

step-by-step explanation:

the image is given below

since the options are not given so we draw it from the equation

the given equation is

y = (x-1) (x+4)

y = y² + 3x - 4

the above equation is a quadratic equation which will have two roots. if we draw the graph for it, it will look like this
