Answer:
23) x= 3, y = 4
24) Any (x,y) values where x = 1.5 - 2y
Step-by-step explanation:
For the first system(23), it goes like this
[1 2 | 7]
[2 1 | 8]
We need to do L2 = L2 - 2L1, so now it is
[1 2 | 7]
[0 -3 |-6]
So, now we have:
-3y = -6 *(-1)
3y = 6
y = 2
x + 2y = 7
x + 4 = 7
x = 3
Now for system 24, we have:
[-1 2 | 1.5]
[2 -4| 3]
We do L2 = L2 + 2L1, so we have:
[-1 2 | 1.5]
[0 0| 0]
So there are infinite solutions for this system. The solution for this system will be each (x,y) pair where x = 1.5 - 2y.
Answer:
Its 4 and -4 :)

Answer:
y - 2 = 1/2(x - 3)
Step-by-step explanation:
In this question, we need to write the given information in point-slope form.
Point-slope form: y - y1 = m(x - x1)
We know that our slope is 1/2
We are also given a coordinate: (3, 2)
Plug in the information to its correct spot in the equation:
y - 2 = 1/2(x - 3)
Your point-slope form would be: y - 2 = 1/2(x - 3)
Answer:
it is 8
Step-by-step explanation:
because EG is E+G which is 8+3 which equals 11 so it is 8
