Answer:
b=8
Step-by-step explanation:
7b-7-8b=-15
Combine like terms
-b-7=-15
Add 7 on both sides
-b=-15+7
-b=-8
Divide by -1
b = 8
(9,3) I believe. Because to get from -3 to -9 you multiply by three, as well as 5 to 15. So you simply multiply multiply these coordinates by three.
Answer:
196
Step-by-step explanation:
half the middle number and then square it
14² = 196
(y + 14)(y + 14)
Answer:
On the context of the problem, the slope means the total paid for every month that the apartment is rented, 900 per month in this case, while the y-intercept means the initial cost for renting the apartment, 1400 upfront in this case.
Step-by-step explanation:
This function is linear, which means that it increases at a steady rate and has the following form:

Where "a" is the slope or the rate at which "y" changes for every change in "x". While "b" is the number at which the function crosses the "y" axis.
On the context of the problem, the slope means the total paid for every month that the apartment is rented, 900 per month in this case, while the y-intercept means the initial cost for renting the apartment, 1400 upfront in this case.
Answer:
The answer simplifies to zero
Step-by-step explanation:
3 sqrt(128) - 2 sqrt(6) * 4 sqrt(3)
3 sqrt(128) - 8 sqrt(6*3)
3sqrt(128) - 8 sqrt(18)
3 sqrt(64*2) - 8 sqrt(9*2)
3 sqrt(64)sqrt(2) - 8 sqrt(9) sqrt(2)
3 * 8 * sqrt(2) - 8 * 3 * sqrt(2)
24 sqrt(2) - 24 sqrt(2)
