Answer: There were 89 retail stores in 1997.
Step-by-step explanation:
Hi, to answer this question, first, we have to calculate the number of years since 1990(x).
1997-1990 = 7 years
Now, we simply substitute x=7 (years) in the equation given
y=11x+12
y=11(7)+12
y=77+12
y = 89 retail stores
There were 89 retail stores in 1997.

Answer:
ans is C. 63 ft.
Step-by-step explanation:
u, tree base n tree top form a right-angle triangle w/
an angle of 49deg
adjacent side = 55'
opposite side = tree height
using trig fn tan(angle)=opposite/adjacent
tan(49deg)=tree height/55'
tree height=55'*tan(49deg)
=63.27' rounding to 63 ft.
Applying the rational roots theorem because of the -9 and 4, -3/2 looks like a good bet because -3 is a factor of -9 and 2 is a factor of 4.
Plugging x = -3/2 into the function we have
4(-3/2)^4 + 8(-3/2)^3 - 7(-3/2)^2 - 21(-1.5) - 9 = 0
so -3/2 is a zero
x = 1 and x = -3/4 are not zeroes.
Answer:
a^2 + b^2 - c^2 + 2ab
Step-by-step explanation:
(a + b - c)(a + b + c)
1. expand
(a^2 + ab + ac + ba + b^2 + bc - ca - cb - c^2)
2. rearrange,
(a^2 + b^2 - c^2 + ab + ba + ac - ca + bc - bc)
3. add and subtract
(a^2 + b^2 - c^2 + 2ab)
