Since she is doubling the box it will be 2 times bigger
y + 7 = 
(x + 4)
the equation of a line in ' point- slope form ' is
y - b = m(x - a)
where m is the slope and (a, b ) a point on the line
here m = and (a , b ) =( - 4, - 7)
y + 7 = (x + 4) → equation in point- slope form
(50-(x*50))+(40-(y*40))+20= discounted with 2 coupons
110-(z*110)= the price with the total coupon.
I believe these are the correct answers
Hello :
<span>
y=5x+8
y= -4x-1
5x+8 = -4x-1
9x =-9
x = -1
y = 5(-1)+8 = 3
</span><span>ordered pair is the solution to the system : ( -1 , 3)</span>
