Answer:
Algebra tiles would not be a good tool to use to factor because you would need to drag an x-squared tile, 18 x-tiles, and 80 plus tiles and it would take a lot of time to drag that many tiles on the board and there might not be enough space to hold all of them. and do u have time to drag 80 tiles? lol
Step-by-step explanation:
Answer:
<em>N = 1/2x + 6</em>
Step-by-step explanation:
We know that Jane has 6 more shoes than 1/2 of what Mercedes has. We can use this information to make an equation.
<em>N (or number of shoes Jane has) is equal to 1/2x (or the number of shoes Mercedes has) plus 6.</em>
When written out we get our answer of:
<em>N + 1/2x + 6</em>

4(2y - 3)
y = 2
<u>Step 2: Evaluate</u>
- Substitute in <em>y</em>: 4(2(2) - 3)
- Multiply: 4(4 - 3)
- Subtract: 4(1)
- Multiply: 4
Answer:
The second answer is the right one
Step-by-step explanation:
Let a be the average rate of change in the interval [0,4] for the function A
● a = (16-0)/(4-0) = 16/4 = 4
The average rate of change in [0,4] is 4 for the function A
Let b be the averagerate of change in [0,4] for the function B
● f(4) = 2×4-1 = 8-1 = 7
● f(0) = 2×0 -1 = -1
● b = (f(4)-f(0))/(4-0)= (7-(-1))/4 = 8/4 = 2
So the average rate of change in[0,4] is 2 for the function B
