Answer:
y = 2^x +5
Step-by-step explanation:
The number of new houses doubles each month, so the base (b) is that multiplier, 2. Then x is the number of months since the construction started (presumably at the end of the open house). If you want x to be something else, then h needs to be chosen so that (x -k) is the number of months the doubling has been taking place.
The value h represents the initial build of 5 houses. This is confirmed by the number 261 = 256 + 5 = 2^8 +5.
So, your equation for the number of houses built over time is ...
y = 2^x +5
B. 33.5 is your answer
First you want to add 12+4 because it is in parentheses
8.5+16x2-7
Then you multiply 16 by 2
8.5+32-7
Then you add 8.5 to 32
40.5-7
Then you subtract 7 from 40.5 giving you your answer
33.5
Answer:
see below
Step-by-step explanation:
Slope intercept form is y = mx+b where m is the slope and b is the y intercept
y = x-7
m = 1
b = -7
y = 4
m=0
b = 4
y = -2x+3
m = -2
b = 3
Answer:
55
Step-by-step explanation:
Answer:
C) both
Step-by-step explanation:
-4x+7=2y-3
Plug in
(2,1)
-4(2) +7 = 2(1)-3
-8 + 7 = 2 - 3
-1 = -1
So (2,1) is the solution
(5,-5)
-4(5) +7 = 2(-5)-3
-20 + 7 = -10 - 3
-13 = -13
So (5,-5) is the solution
Answer:
C) both
