I'm not sure what we're being asked to find here but if this is putting the equation into slope-intercept form, then it's:
3x - y = -1
-y = -3x -1
y = 3x - 1
And
-3x + 4y = -14
4y = 3x - 14
y = 0. 75x - 3.5
But if you're asking to solve this as systems of equations then:
3x - y = -1
-3x + 4y = -14
Solving by elimination. Add both equations together.
3x - y = -1
+ -3x + 4y = -14
———————————
3y = -15
Divide both sides by 3.
y = -5
Now that we know the numerical value of y, we can solve for x.
3x - y = -1 -3x + 4y = -14
3x - (-5) = -1 -3x + 4(-5) = -14
3x + 5 = -1 -3x - 20 = -14
3x = -6 -3x = 6
x = -2 x = -2
So, the solution/coordinates to these system of equations are (-2, -5).
Answer:
i believe its the one with the dot at 2.6 for the square root of 7
Step-by-step explanation:
8 goes into 64 8 times. 8*8 equals 64. For example 8+8+8+8+8+8+8+8=64 that is 8 written out 8 times. I hope that helped :D
Answer:
P(1 |F) = 10/17
Step-by-step explanation:
Let events
1 = restaurant 1
2 = restaurant 2
F = full-time worker chosen
P = part-time worken chosen
P(1 and F) = 1/2 * 10/16 = 5/16
P(2 and F) = 1/2 * 7/16 = 7/32
P( (1 or 2) and F ) = P(F) = 5/16+7/32 = 17/32
P(1 | F) Probability of choosing restaurant 1 given a full-time was chosen
= P(1 and F) / P(F)
= 5/16 / (17/32)
= 5/16 * 32/17
= 10 / 17
