Step-by-step explanation:
27 weeks minimum.
To get this, I divided 520 and 20. It equals 26, but there are still 5 dollars left. She cannot buy the bracelet without them, so you must add on 1 more week.
Good luck!
Answer:
what is r90 and I will be able to answer
Step-by-step explanation:
Standard form of an exponential function is y=ab^x
when x=0, y=3, 3=ab^0, so you can figure out that a=3
when x=-1, y=6, 6=3b^(-1), b^(-1)=2, b=1/2
so the equation is y=3(1/2)^x
Answer:
y>=2x-2
Step-by-step explanation:
You're gonna want to make one side equal to zero so subtract 8 from both sides
8x-4y-8 ≤0
Then you want to move the x and the constant back over by adding (-8x+8)
-4y ≤-8x+8
Then you'd flip the inequality sign and divide both sides by 4
y>=(8/4)x-(8/4)
Then you'd break the big numbers and make them exponents
y>=(2^3/2^2)x-(2^3/2^2)
Then you reduce the fraction by removing what appears in the numerator and denominator which in this case is 2^2
So your answer is: y>=2x-2
