C = 3b+2d is the same as 3b+2d = C
Let's isolate d. To do this, we first need to subtract 3b from both sides
3b+2d = C
3b+2d-3b = C-3b
2d = C-3b
Then divide both sides by 2
2d = C-3b
2d/2 = (C-3b)/2
d = (C-3b)/2
Take note of the parenthesis as they are very important. We want to divide ALL of C-3b over 2. We don't want to just divide -3b over 2.
The answer choices you have aren't 100% clear but I have a feeling your teacher meant to say d = (C-3b)/2 instead of d = C-3b/2 for choice A
If that assumption is correct, then the answer is choice A.
Answer:
Varying
Step-by-step explanation:
The reason why the rate of change is varying is because the dots on the graph do not connect to make a straight line when you draw a line through the dots. When the dots connect via a straight line, it is also known as a proportional relation. A straight line would be a constant change.
The absolute value of 7 would be 7
The slope formula is y2-y1/x2-x1 so 5-(-1) =6 Then. 1-(-1)=2 so 6/2. =3. THE ANSWER IS 3
Answer:
<h2><em><u>
2/9 is the answer.</u></em></h2>
Step-by-step explanation:
<em><u>1. First, make an equation.</u></em>
<em><u>Given:</u></em>
8/9 = length of wire
2/3 = length of a part of the wire
E = 8/9-2/3
<em><u>Unknown:</u></em>
Second part of wire
<em><u>2. Make the numbers have equal denominators</u></em>
2/3 * 3/3
= 6/9
<em><u>3. Solve</u></em>
8/9 - 6/9
= 2/9
