Answer:
5y = x + 11
Step-by-step explanation:
Given parameters:
Equation of the line ;
y = -5x + 1
Coordinates = (2, -1)
Find the equation of a line perpendicular;
Solution:
A line perpendicular to y = -5x + 1 will have slope that is a negative inverse of the given one.
Equation of a straight line is expressed as;
y = mx + c
y and x are the coordinates
m is the slope
c is the y-intercept
So, the slope of the new line perpendicular is 
;
Now let us find the y-intercept of the new line;
x = -1 and y = 2
2 = x (-1) + c
c = 2 + = 
The equation of the new line is;
y = x +
or multiply through by 5;
5y = x + 11
Answer:
.
Step-by-step explanation:
It is given that a die is rolled one time. So,
Sample space : 
Number is greater than 3 : 
Number is odd : 
Number greater than 3 and an odd number : 
It is conclude that,
The probability of getting a number greater than 3 and an odd number is
Therefore, the required probability is .
Answer:
Number = 15.
Step-by-step explanation:
Given : If you multiply a number by 3 and then subtract 5, you will get 40.
To find : what is the number.
Solution : We have given if you multiply a number by 3 and then subtract 5, you will get 40.
According to question :
Let the number = x
Multiply is with 3 = 3x
Subtract 5 from it we get 40 .
3x -5 = 40
On adding both sides by 5
3x = 45 .
On dividing both sides by 3
x = 15.
Therefore, Number = 15.
Answer:
y ≈ 2.1
Step-by-step explanation:
If you look at the graph and locate on the x axis 2, you can see that directly above on the line is a little more than 2.
