Answer:
perpendicular
Step-by-step explanation:
4*(-1/4)=-1, so lines are perpendicular
Answer:
26, 64
Step-by-step explanation:
M=N-38
M+N=90
M=26
N=64
Hey girl! It's me again to explain this to you :)
Number 21.) If we start from our y-intercept -2 and move up 2 on our y-axis we get to point (0,0). If we move over 1 space to the right, we are on (1,0), which is the x-intercept.
Slope: 2/1 or just 2
Y-intercept: -2
You didn't ask for this but i'm gonna write it anyways. The equation for this line is y=2x-2
Number 22.) If we start from our y-intercept 2 and move down 2 on your y-axis we get to point (0,0). If we move over 1 space to the right, we are on (1,0), which is the x-intercept.
Slope: -2/1 or just -2
Y-intercept: 2
Again you didn't ask for this but the equation for this line is y=-2x+2
Hope this helped you understand and again make this brainliest and reply if you need more help or have any more questions :)
Step-by-step explanation:
Solution: We are given that the correlation coefficient between ages and numbers of violations is -0.61.
The ages and numbers of violations related as age increases, violations decrease.
Therefore, the option c. as age increases, violations decrease.
The correlation coefficient measures the strength of linear association between two variables. The value of the correlation lies between -1 to 1. -1 indicates the perfect negative linear relationship between two variables. The negative values of correlation means as the one variable increases, the other variable decreases. The correlation of +1 indicates that there is perfect positive linear relationship between two variables. The positive values of correlation means as the one variable increases, the other variable also increases.
In the above statement the correlation value is negative, therefore indicating as age increases, violations decrease.
Answer:
4x + 18
Step-by-step explanation:
This is called a composite function, meaning passing the range of one function as a domain of another function.
For f(f(x)), the inner-function's range is passed as the domain of the outer function.
We can do so by substitution,
The range of f(x) can be written as 2x + 6 for any defined x values,
So we will substitute 2x + 6 as the 'x' of another function which is in this case
f(x) again, so it looks like this 2(2x+6) + 6 which can be simplified into
4x + 18
