Answer:
y-intercept (0,1)
multiplicative rate of change: b
Step-by-step explanation:
If a table represents an exponential function of the form , then the y-value that corresponds to x=0 is 1.
In other words, the y-intercept (0,1) must be present in the table.
Also the ratio of a subsequent y-value to the previous y-value should give a value of b.
In other words the multiplicative rate of change from the table must be equal to b.
Move 9 over to the other side so your equation looks like this:
9n = 9 - 9
Then simplify
9n = 0
n = 0
Answer:
see below
Step-by-step explanation:
the temperature rose by 11. +11
the temperature dropped by 14 - 14
Let t = temperature
The expression is
t + 11 -14
Let x be positive chips and y be negative chips
xxxxx xxxxx x
yyyyy yyyyy yyyy
The result is -3
t-3
Step-by-step explanation:
y+7=6(x-4)
y+7=6x-24
y=6x-31
<span> −3|x + 7| = −12
* </span><span> −3(x + 7) = −12
-3x - 21 = -12
-3x = -12 + 21
-3x = 9
x = 9/-3
x = -3
</span>
* −3*[ -(x + 7)] = −12
3x + 21 = -12
3x = -12 -21
3x = -33
x=-33/3
x = -11
answer:
x = -11 and x = -3
