Step-by-step explanation:
4 times the sum of x and y is: 4(x+y) where you're multiplying the expression x+y four times. the sum of 4 times x and y is: 4x+y where you only multiply x four times and y is left out of the multiplication.Jan
Answer:
22, 50, 106, 218
Step-by-step explanation:
Using the recursive formula with f(0) = 8
Substitute n = 1, 2, 3, 4 into the recursive formula and evaluate
f(1) = 2f(1-1) + 6 = 2f(0) + 6 = (2 × 8) + 6 = 16 + 6 = 22
f(2) = 2f(1) + 6 = (2 ×× 22) + 6 = 44 + 6 = 50
f(3) = 2f(2) + 6 = (2 × 50) + 6 = 100 + 6 = 106
f(4) = 2f(3) + 6 = (2 × 106) + 6 = 212 + 6 = 218
The answer is 43-30x because you always add the parenthesis first which now you have 18+25-10x3 then you calculate the product 18+25-30x. after all that you then add all the numbers and get 43-30x. hope this helps
56 / 5 = 11.2...so 11.2 x 5 = 56
Say you have 3 cakes. How many cakes would you have eaten if you ate 1/3 of the three cakes? One, you have eaten one cake, out of the three you have.
How many cakes do you have left if you eat 2/3 of the three cakes? Two, you have eaten 2 cakes, and have 1 cake left.
It is a similar approach here, except the confusing part is working "forward", when you really have to work "backward". If you have driven 30 miles, and you have driven 2 parts out of the trip when there is 3 parts of the trip, how many miles have you driven? Hint: Dividing 30 by 2 gives you what fraction of the distance to Jeff's grandmother?
