Answer:
The answere is y= 1/4x-2
Step-by-step explanation:
subtract 2x from both sides to get -8y=-2x+16
then divide -8 on all terms to get y=2/8x-2
then simplify the 2/8 to get y=1/4x-2
5^4 power. We can identify this because 5 is multiplying itself 4 times.
Hope this helps!
Didn't use algebra but Gary would be 3 and Karen would be 13 so in 2 years Gary would be 5 and Karen would be 15 and 5 x 3 = 15 so ya.
Answer:
3m and 9m
Step-by-step explanation:
length of the rectangle = 2w+3
width of rectangle = w
area = L*W
if area = 27m²
then (2w+3)w=27
=2w²+3w-27=0
using factorization w= 3 or -4.5
w=3m
L=9m
Answer:
4(x-4.5)^2
Step-by-step explanation:
h(x)=4x^2-36x+81
=4(x^2-9x)+81
=4(x^2-9x+20.25)-(4)(20.25)+81
=4(x-4.5)^2
