Answer: $19,610
Step-by-step explanation:
53000(.37)=19610
<em><u>Option B</u></em>
The result of addition is 2y = 24
<em><u>Solution:</u></em>
Given that we have to add the equations
<em><u>Given equations are:</u></em>
5x - y = -1
-5x + 3y = 25
We have to add both equations
This is similar to adding numbers. i,e 1 + 2 = 3
<em><u>For adding variables,</u></em>
When adding or subtracting terms that have exactly the same variables, you either add or subtract the coefficients, and let the result stand with the variable.
Example: 2x + 3x = 5x
Keeping this in mind, let us add the given equations
5x - y = -1
-5x + 3y = 25
----------------------------
0 + 2y = -1 + 25
[ 5x and -5x cancels each other. Combine -y and 3y which gives 2y]
2y = 24
Thus Option B is correct
Answer:
c.Observational study. The variable of interest is the result of either correct or incorrect to each trial.
Step-by-step explanation:
Observational study is the type of study when a researcher don't influence the outcome of an experiment by imposing a treatment and only observe the outcome of an experiment. A nine year old tested professional observes therapists choices and so this is the observational study.
A nine year old tested professional observes therapists choices and the choice of therapist can be correct or incorrect. So, the variable of interest is the result of either correct or incorrect to each trial.
Answer: 2
Each time x increases by 2, the outputs are multiplied by 4 (eg: 3 to 12 is times 4, or 12 to 48 is times 4)
Take the square root of 4 to get 2. So each time x increases by 1, y is doubled
x = 0, y = 3
x = 1, y = 6 <<-- y is doubled
x = 2, y = 12 <<-- y is doubled
and so on
