10p-30=40 is equivalent to 5(2p-6)=40
This is because you have to distribute 5 to 2p and negative 6
So 5 times 2p is 10p and 5 times -6 is -30
When you put this all together you get 10p-30=40
It would be D because when you solve for the vertex, first it says in the parentheses to add 3 which is to move 3 to the left. Then you see outside the parentheses to subtract 2 which is to move down. This is how you know it is D
We can make and use the equation: <em>A = 160( 1.03 )^y</em>: A = amount, 160 = amount put in, 1 + .03 = 1.03 = interest, and y as the number of years, as the money is compounded every year. (This is the compound interest equation, but I put in the numbers)
A) 160 * 1.03 = $164.80, 160 * 1.03² = $169.744 ≈ $169.74
B) 160 * 1.03⁵ = 185.48385 ≈ $185.48
The expression is the same as saying (((((160 * 1.03)1.03)1.03)1.03)1.03). This is like multiplying 160 * 1.03, which gives the amount for the first year. Then, that amount is multiplied by 1.03, which is the amount for the second year. This isi repeated until 5 years.
C) 160(1.03)³⁰
It is 24 my man.
Hope that help
