Answer:
Step-by-step explanation:
-21-9k=-8(6k+3)
-21-9k= 48k+24
+9k +9k
-21=57k+24
-24 -24
-45=57k
divide 57 by -45
k= -1.2
idk if that helps, sorry

Answer:
y = 2x - 7
Step-by-step explanation:
Looks like we already have the slope of this line: It is 2. Working with the point (1, -5), we have x = 1 and y = -5 and can from this info easily find the y-intercept, b:
y = mx + b becomes
y = 2x + b, which in turn becomes
-5 = 2(1) + b, or
b = -7,
and so the desired equation is y = 2x - 7
Answer:
No, a negative "integer" can not be greater than a positive one (The opposite)
Step-by-step explanation:
Ex: <u>-2 0 2</u> two is over 0 so it is positive and greater.
Answer:
The statement is correct
see the explanation
Step-by-step explanation:
we know that
The equation of a exponential growth function is equal to

where
y is the area covered by the plant in percentage
x is the time in years since 2000
r is the rate of change
a is the initial value
In this problem we have


substitute the values


In the year 2005

substitute the value of x in the exponential function

48.6% is about 50%
therefore
The statement is correct
