Use the formula slope= y-y/x-x
-10-r/-2-8= 1/10
-10-r/-10= 1/10
Multiply the denominator (-10) on both sides
-10-r= -1
Add -10 to both sides
-r= 9
r= -9
Hope this helps!
Answer:
The minimum value of this quadratic function is -4.
At the point (-4, 0), the x-axis intercepts with the quadratic graph.
There is 1 root of this quadratic equation.
Approximately, when y=1, the x value could be -5 or -3.
Answer: On factoring out coefficient of variable for (4h-3) we get:
Explanation:
Coefficient of the variable is the number which is multiplying with the variable. Generally coefficient is written before the variable for example: 2 is the coefficient of x in equation (2x+1).
Here in the given equation (4h-3) the coefficient of the variable 'h' is 4.
When we factor out the coefficient of the variable 'h' from the given equation we will get:
Answer:
B. Variance = r2 = 0.7225
Step-by-step explanation:
Given the correlation coefficient, variance is obtained by squaring the correlation coefficient to obtain what is also know as coefficient of determination. Gives information on the predictive power of the model
Answer:
1 ≤ x ≤ 6 Option A
Step-by-step explanation:
When graph is constant it means, value of graph ( y-values) not to be change different values of x in given interval.
In other words, graph must be parallel to the x axis is known as the constant graph.
A function is a measure of the rate of change of function values with respect to change in input values.
In given graph horizontal line is lie on the interval from x ≥ 1 to x ≤ 6.
So, option A is correct.
