Answer:
2
Step-by-step explanation:
Logarithm base 6 of 36 is 2 .
Hi there!
To find the answer, you divide one of the numbers by 3, and some others by -3.
I can show you how to do so! :D
243 ÷ -3 = -81
-81 ÷ 3 = 27
27 ÷ 3 = 9
Next three terms -
9 ÷ 3 = 3
3 ÷ 3 = 1
1 ÷ 3 = 0.3333, the 3 is repeating over and over again
I think this is the answer, based off my notes :)
That's your pattern!
Hope this helps!
Message me if you need anything else, I'd be happy to answer any other questions! :D
Answer x=-2,-6
The roots (zeros) are the
x
x
values where the graph intersects the x-axis. To find the roots (zeros), replace
y
y
with
0
0
and solve for
x
x
.
All you have to do is substitute the y value from the 1st equation into the second equation and solve...
a) y= 2-x
5x + 4y = 5
Substitute (2-x) into the second equation anywhere there is a y...
5x + 4y = 5
5x + 4(2-x) = 5
Now solve
5x + 8 - 4x = 5
5x - 4x + 8 = 5
x + 8 = 5
x = -3
Now that you have a solution for x, substitute -3 into either of the original equations anywhere there is an x then solve for y...
y = 2 - x
y = 2 - (-3)
y = 2+3 = 5
You solved for x and got -3 and solved for y and got 5, so your solution set is
(-3, 5).
Now check it by substituting both numbers into one of the original equations and you should have a true statement if it is correct...
y = 2 - x
5 = 2 - (-3)
5 = 2+3
5 = 5
True statement... it checks!
note* during the check, if the equation would have worked out to something like 2 = 5, then that is a false statement therefore the solution set would be wrong and you'd have to go back and find the mistake.
