Answer:
(1, 1 )
Step-by-step explanation:
Given the 2 equations
y = - 5x + 6 → (1)
y = 3x - 2 → (2)
Since both equations express y in terms of x, equate the right sides
3x - 2 = - 5x + 6 ( add 5x to both sides )
8x - 2 = 6 ( add 2 to both sides )
8x = 8 ( divide both sides by 8 )
x = 1
Substitute x = 1 into either of the 2 equations for corresponding value of y
Substituting x = 1 in (2)
y = 3(1) - 2 = 3 - 2 = 1
Solution is (1, 1 )
I think it would be b or c
Answer:
0.7 is the growth factor
0.3 is the growth rate
Step-by-step explanation:
Here, we want to get the growth rate and the growth factor
Let us consider the general form of an exponential equation
That will be;
y = a(1 + r)^n
The growth rate is r
while the growth factor is the term (1 + r)
From the given exponential function;
-0.3 is the rate of increase
Growth rate is 1-0.3 = 0.7
