Answer:
Option (4)
Step-by-step explanation:
Equation of a line passing through a point and with slope 'm' is,
y - y₁ = m(x - x₁)
Given → Slope 'm' = -2
Point through which the line is passing is (-1, -2)
x₁ = -1 and y₁ = -2
Therefore, equation will be,
y + 2 = -2(x + 1)
y = -2x - 2 - 2
y = -2x - 4
Option (4) is the correct option.
20 bills in all
6 one dollar
3/10
19 bills
2 10 dollar
2/19
3/10*2/19=6/190
Answer: 6/190 probability
Answer:
A) Neither
Step-by-step explanation:
If two lines have same slope then they are parallel lines
If slope of line1* slope of line 2 = -1
The the two lines are perpendicular
In this question slope of line = 2\7
Slope of line 2 = 7\2
Lets denote the numbers x and y:
The sum of two numbers 94 → x + y = 94
Their difference is 12 → x - y = 12
We have:
x + y = 94
x - y = 12
---------------- Add both equations
2x = 106
x = 106/2
x = 53
Using first equation:
x + y = 94
53 + y = 94
y = 94 - 53
y = 41
A/ The numbers are 53 and 41.
