Y = 6x - 4
basically, we just sub answer choices in to see which ones make the equation true.
answer is : (0,-4) , (1,2) , (3,14)
Answer:
it's 4
Step-by-step explanation:
Ok so this is the first page
1.
78 pizzas. 20% of 65 is 13. Add that to 65 and you get 78 pizzas.
It is a 1.08% decrease. When you divide 65/60 you get 1.08. Im not 100% sure about this one
2.
Online store=$208 and the superstore=$224
The difference is $16 so it would be cheaper to get it at the online store
3.
It is $4000. For the first year you would multiply $20,000 by 5% which is 20000*.05=1000. Then multiply 1000 by 4 years to get $4,000
Instead of multiplying the 1000 by 4, multiply by 2 to get 2000. Subtract 4000-2000 to get 2000. You saved $2,000
Answer:
6
Step-by-step explanation:
Arc length = radius * central angle
s = rθ
A circle is 2π radians, so 1/3 of that is 2/3 π.
Given that s = 12 and θ = 2/3 π:
12 = r (2/3 π)
r = 18/π
r ≈ 6
For short term remembering: It really works if you take notes in class. I also found making connections to things you've experienced helps too.
For long term remembering - I found reviewing what you've learned recently is extremely useful. You can usually do this once in a couple of days until you're sure you can remember it.
Hope this helps!
