$(y^2-7y-5)-(-3y^2+3y-4)=y^2-7y-5-(-3y^2)-3y-(-4)\\\\=y^2-7y-5+3y^2-3y+4$

<em>combine like terms</em>

$=(y^2+3y^2)+(-7y-3y)+(-5+4)=\boxed{4y^2-10y-1}$

Jackson purchases a new car for $48,000. The car's value can be modeled by the

vekshin1

We have been given that Jackson purchases a new car for $48,000. The car's value can be modeled by the following exponential function: $y = 48000(0.76)^t$ where y represents the car's value and t represents time in years. We are asked to find the decay rate as a percentage.

We know that an exponential decay function is in form $y=a\cdot (1-r)^x$ , where,

y = Final value,

a = Initial value,

r = Decay rate in decimal form,

x = time.

Upon comparing our given function $y = 48000(0.76)^t$ with standard decay function $y=a\cdot (1-r)^x$ , we can see that $1-r=0.76$ .

Let us solve for r.

$1-1-r=0.76-1$

$-r=-0.24$

$r=0.24$

Let us convert 0.24 into percentage.

$0.24\times 100\%=24\%$

Therefore, the decay rate is 24%.
