First, you need to isolate the x in the first equation.
-x + 5y = 1
Subtract 5y from both sides, leaving you with the following equation:
-x = 1-5y
Because you are trying to solve for positive x and not negative x, you need to make x positive. Therefore you divide both sides by -1. In Algebra, when 1 is the coefficient of the variable, it is not shown, but it is still there. The new equation will be the following: x = 5y-1
Now you just need to substitute the x within the second equation for the x equation we just solved for.
Therefore, the right answer will be 2(5y-1)+4y= -4. Now, all you have to do is choose the answer that states exactly that, which is the first choice.
Answer: B
Step-by-step explanation:
2/3 x 2/1 =4/3
Yes, 0.09 squared, or <span>0.0081, is a rational number.</span>
X - 8 = 23
x = 23 + 8
x = 31 <== originally on their 31 yard line
Answer: nonresponse bias
Step-by-step explanation:
According to the information obtained, we can say that it is a non-response bias, since the sample obtained to extrapolate the result was not homogeneous, so these biases arise when the type of response to the non-response is affected in a social experiment. meet a standard among the population muesta¡ra.
Cognitive biases are found in ideas that make us partial. These thoughts, along with certain external circumstances, create what are known as response biases.
