Answer:
(10, 14)
Step-by-step explanation:
To solve this system let's use substitution:
Solve the first equation for x, obtaining x = 24 - y, and then substitute 24 - y for x in the second equation:
3(24 - y) + 5y = 100
Performing the indicated multiplication, we get:
72 - 3y + 5y = 100
Combining like terms results in 72 - 100 = -2y, or -28 = -2y
Thus, y must be 14.
If y = 14, then the first equation tells us that x = 10.
Check: Is this true? 3(10) + 5(14) = 100 YES
The solution is (10, 14).

Answer:
-27+84n
Step-by-step explanation:
2. I think the answer is 24
subracting the last 2 inequalities we get
6x + 7y <= 42
3x + 2y <= 18 subtract:_-
3x + 5y <= 24

Step-by-step explanation:
Answer:
Using y = mx + c
slope = -17+5/3-1 = -12/2 = -6
Using point (1 , - 5)
y + 5 = -6(x - 1)
y + 5 = - 6x + 6
y = - 6x + 6 - 5
y = - 6x + 1
Hope this helps.
