Answer:
r = -8/5
Step-by-step explanation:
-7 log4 (-10r) = -14
Divide each side by -7
-7/-7 log4 (-10r) = -14/-7
log4 (-10r) = 2
Raise each side to the base of 4
4^ log4 (-10r) = 4^2
-10r = 16
Divide each side by -10
-10r/-10 = 16/-10
r = -116/10
r = -8/5
Answer:
C. A reflection over the line y = -x
Step-by-step explanation:
You need to reflect that over a line that goes between the two of them. That imaginary line has a rise of -1 (it goes down 1 unit) and a run of 1 (it goes one unit to the right). In other words, the slope is -1. The line should also have a y-intercept of 0 it starts at (0,0).
Put that information in slope-intercept form
y = -1x + 0
You can take out the 0 because it adds nothing to the equation, and you can remove the one because of the same reason, but leave the negative sign.
y = -x
Answer:
C.
Step-by-step explanation:
For Function 2
x=1 y=8
x=2 y=11
8=m+b
11=2m+b
11-8=2m-m
m=3
8=3+b
b=5
y=3x+5
Function 1
y=4x+5
Function 2
y=3x+5
....................
Function 1 has the same y-intercept and greater slope than Function 2.
Answer:
