Answer:
75
Step-by-step explanation:
If you flip the numbers around then all you have to do is 82-7 and when you do this then you get 75 which is the answer
Answer:
Step-by-step explanation:
1. Begin by graphing the y-intercept of +1. The y-intercept exists where x = 0; therefore, the coordinate of the y-intercept is (0, 1). Plot this point.
2. From the y-intercept, incorporate the slope by going up or down then right or left. The slope is 2, which can be written as +2/+1; this means from the y-intercept you will move up 2 units and then over to the right 1 unit and make another point.
3. Connect the 2 points to make your line.
Answer:
(a)
dependent
(b)
x = -3t - 12
y = -5t - 16
z = t
Step-by-step explanation:
2x - 3y - 9z = 24 Eq. 1
x + 3z = -12 Eq. 2
-3x + y - 4z = 20 Eq. 3
2x - 3y - 9z = 24
(+) -9x + 3y - 12x = 60 3 * Eq. 3
--------------------------------
-7x -21z = 84 Eq. 4
7x + 21z = -84 7 * Eq. 2
(+) -7x - 21z = 84 Eq. 4
-----------------------------
0 = 0
(a) The system is dependent.
(b)
z = t
x + 3z = -12 Eq. 2
x + 3t = -12
x = -3t - 12
2x - 3y - 9z = 24 Eq. 1
2(-3t - 12) - 3y - 9t = 24
-6t - 24 - 3y - 9t = 24
-3y - 15t = 48
-y - 5t = 16
-y = 5t + 16
y = -5t - 16
x = -3t - 12
y = -5t - 16
z = t
Answer:
the answer has to be 3(17-y)
Step-by-step explanation:
I'm pretty sure about that cause what I did at first is subtract the numbers.
<em>6</em><em>0</em><em>-3y-9</em>
=51-3y
factor our 3 from the expression.
3(17-y)
