Answer:
Step-by-step explanation:
Divide by - 5
-5(2w + 1) / - 5 = 25 / - 5
2w + 1 = - 5
Subtract 1 from both sides.
2w + 1 - 1 = - 5 - 1
2w = - 6
Divide by 2
2w/2 = -6/2
w = - 3
-5(2w+1)=25
Multiply both sides by -5
(-5)(2w)=-10w
(-5)(1)=-5
-10w-5=25
Move -5 to the other side. Sign changes from -5 to +5.
-10w-5+5=25+5
-10w=30
Divide by -10 for both sides
-10w/-10=30/-10
w=-3
Answer: w=-3
Answer:
1/3
Step-by-step explanation:
To find the common ratio, take the second term and divide by the first term
9/27 = 1/3
Check by dividing the third term by the second
3/9 = 1/3
and so forth
1/3 = 1/3
etc
The common ratio is 1/3
The given expression are just three examples of the many possiblecombinations that can add up to 800.
To find three different ways in which two numbers can be added to equal 800, we can explore different combinations. Here are three examples:
1. Combination 1:
600 + 200 = 800
In this combination, the numbers 600 and 200 are added together to equal 800.
2. Combination 2:
400 + 400 = 800
In this combination, the numbers 400 and 400 are added together to equal 800.
3. Combination 3:
350 + 450 = 800
In this combination, the numbers 350 and 450 are added together to equal 800.
The key is to find two numbers whose sum equals 800. You can experiment with different pairs of numbers and add them together to find other valid combinations.

Answer:
Second graph
Step-by-step explanation:
The second graph is the correct one. Why? because the y intercept is (0, 3), and also because the base, 1/5, is between 0 and 1, which leads to a decaying exponential graph.
