D and C.
You already stated the total ratio is 14:5 so that gives you the answer of choice C.
And 5+9=14 so that gives you the answer of choice D.
The answer is choice B in the upper right hand corner.
Choice B is the graph that is a straight line and it's a single unbroken straight line. There are no gaps or jumps or any kinds of bends like choice A shows. Choice A is an absolute value graph, which is the result of gluing together two linear functions. Overall, graph A is considered nonlinear. Choices C and D are nonlinear as well.
Answer: Step 5
===================================================
Reason:
The order of operations is PEMDAS
- P = parenthesis
- E = exponents
- M = multiplication
- D = division
- A = addition
- S = subtraction
The multiplication and division are on the same level of precedent, and the same goes for addition and subtraction. Some math textbooks may refer to PEMDAS as BODMAS, which is basically the same thing.
Notice how division comes before addition. So we must compute the
portion first before adding in step 4.
This is what steps 4 and onward should look like

So that's why the error is in <u>step 5</u>
If there was parenthesis around the "2+10", and we had
, then step 5 given by your teacher would be correct.
Answer:
I think it is B,D, and E. Hope that helps.
6&7. Also -7,-6 is the correct answer
