Answer:
Step-by-step explanation:
Given expression is 
Let us perform the operations inside the parentheses first.
Answer:
4 and 4/6
Step-by-step explanation:
We are looking for k in the equation
(x+4)(x+k/4) = x^2+7x+k
The left hand side expands to:
x^2+(4+k/4)x+k = x^2+7x+k
Comparing coefficients for the linear terms, we have the equation
(4+k/4)=7
Solving for k:
16+k=28
k=12
Thus the number to be subtracted is 15-k=15-12=3
The correct statement about when a scatterplot is constructed is the independent variable is the input variable and should be represented by the x-axis. Option A
<h3>Steps in constructing a scatterplot</h3>
- Choose independent and dependent variable
- Draw a known x-axis for the independent variable
- Add y-axis for the dependent variable
- Make all the points in the scatterplot
- Label graph and axes
From the given steps, we can see that when a scatter plot is constructed, the independent variable is the input variable and should be represented by the x-axis.
Hence, the correct statement about when a scatterplot is constructed is the independent variable is the input variable and should be represented by the x-axis. Option A
The complete question is;
Which statement is correct when a scatterplot is constructed? The independent variable is the input variable and should be represented by the x-axis.
The independent variable is the input variable and should be represented by the y-axis.
The dependent variable is the input variable and should be represented by the x-axis.
The dependent variable is the input variable and should be represented by the y-axis.
