Answer:
when x = ±
Step-by-step explanation:
Since we can find a solution for this system of equations we can affirm this is an independent system with solution equal to (x,y) = (3,-1)
* If we graph a dependent system in the slope - intercept form, we can see that the graphs of each one are identical to each (beacuse we are representing the same line).
*An inconsistent system occurs when the equations have the same slope, but different values of intersection with the Y axis.
Answer:
x=8/7
2x times 7 divided by 2 = 8
solve for x
Answer:
The value of x = 110°
Step-by-step explanation:
=> x° + 90° + 90° + 70° = 360 ° { sum of angles of a quadrilateral is 360 }
=> x + 250° = 360°
=> x = 360 - 250
=> x = 110°
Probability of Reggae song: 2/7
Probability of Rock song: 3/6= 1/2
So the <span>probability that the first song is a reggae song and the second is a rock song: (2/7)*(1/2)= 2/14= 1/7
