Amber pays a deposit of $45 dollars to rent a mustang for an upcoming trip. the company also charges $10 per day to rent the mustang. write an equation in slope-intercept form that models this situation if y is the total cost and x is the number of the days amber rents the mustang. plz !

The value of x in this system of equations is 1. 3x + y = 9 y = –4x + 10 substitute the value of y in the first equation: combine like terms: apply the subtraction property of equality: apply the division property of equality: 3x + (–4x + 10) = 9 –x + 10 = 9 –x = –1 x = 1 what is the value of y?

Y=21.95x+10 y=22.45x solve by substitution

Examine this system of equations. what integer should the second equation be multiplied by so that when the two equations are added together, the x term is eliminated? 3/4x+1/7y=6 1/8x-3/5y=16
