Answer:
Option (B)
Step-by-step explanation:
There are two lines on the graph representing the system of equations.
First line passes through two points (-3, 1) and (-2, 3).
Slope of the line =
=
m = 2
Equation of the line passing through (x', y') and slope = m is,
y - y' = m(x - x')
Equation of the line passing through (-3, 1) and slope = 2 will be,
y - 1 = 2(x + 3)
y = 2x + 7 ----------(1)
Second line passes through (0, 1) and (-1, 4) and y-intercept 'b' of the line is 1.
Let the equation of this line is,
y = mx + b
Slope 'm' =
=
= -3
Here 'b' = 1
Therefore, equation of the line will be,
y = -3x + 1 ---------(2)
From equation (1) and (2),
2x + 7 = -3x + 1
5x = -6
x =
x =
From equation (1),
y = 2x + 7
y =
=
=
=
Therefore, exact solution of the system of equations is .
Option (B) will be the answer.
Answer:
11/5 inches
Step-by-step explanation:
total snowfall for the day = snowfall in morning + snowfall in evening
= 8 over 5 + 3 over 5 (all in inches)
= 8/5 + 3/5 (all in inches)
Since the denominators are the same (5), we can simply add the numerators up while keeping the denominator
(8/5 + 3/5) inches= (8+3)/5 inches = 11/5 inches = total snowfall for the day
Good news: they are all like terms
9x + 5x -3x -8x = 3x
Answer:
4/36
Explanation:
There are 6 numbers and if spines twice other 6, if these are multiplied with each other there will be a total of 36 products or probabilities.
On total there are four 12
2 x 6
3 x 4
4 x 3
6 x 2
