We want to use substitution to solve
-5x + 4y = 22 (1)
x - 3y = 0 (2)
From (2), obtain
x = 3y (3)
Substitute (3) into (1).
-5(3y) + 4y = 22
-15y + 4y = 22
-11y = 22
y = -2
From (3), obtain
x = 3y = 3*(-2) = -6
Answer: e. (-6, -2)
Answer:
<u>x=0</u>
all you have to do it plug the diffrent answers into as x and see which one works out, in this case 0 works on both side to get it equale
<u></u>
Answer:
-25, 22, -65, 0
Step-by-step explanation:
Answer:
The year is 2020.
Step-by-step explanation:
Let the number of years passed since 2010 to reach population more than 7000000 be 'x'.
Given:
Initial population is, 
Growth rate is, 
Final population is, 
A population growth is an exponential growth and is modeled by the following function:

Taking log on both sides, we get:

Plug in all the given values and solve for 'x'.

So, for
, the population is over 700,000. Therefore, from the tenth year after 2010, the population will be over 700,000.
Therefore, the tenth year after 2010 is 2020.
Answer:
TRUE
Step-by-step explanation:
y-4 = 2(x-1)
here, 4 is representing the y value and 1 is representing the x value.
And the slope is 2.
