Answer:
3x - y = -5
<u>-3x -3x</u>
<u>-y</u> = <u>-3x</u> <u>-5</u>
-1 -1 -1
y = 3x + 5
Step-by-step explanation:
- subtract 3x from both sides. 3x cancel 3x, but it can't cancel -5 since it doesn't have any x.
- since y is negative, divide both sides by -1.
- the slope here is 3x, but the slope intercept form is y = 3x + 5
Answer: B. Controlled experiment
Step-by-step explanation:
This is a controlled experiment because the variables in the question are manipulated by the researcher. We are told that while one group watches television before going to sleep, the other group does not.
The controllers won't have control over the variables that were used if it was an observational study while for a survey, it has to do with collection of information regarding certain topics or happenings in order to have people's perception on the topic or area of interest.
For this case we propose a rule of three to obtain the number that represents 25% of 37.
So, we have:
37 --------> 100%
x -----------> 25%
Where "x" is the number that represents 25% of 37.
Finally, we have that 25% of 37 is 9.25.
Answer:
25% of 37 is 9.25.
(5x+4)(x+7) = (5x × x) + (5x × 7) + (4 × x) + (4 × 7)=
= 5x^2 +35x + 4x + 28 = 5x^2+39x+28
