Answer:
-7
Step-by-step explanation:
(x,y) --> (0,-7) -7 is the y-intercept
<h3>
Answer: True</h3>
===================================================
Reason:
Replace x with 4 in each inequality
x > 0 becomes 4 > 0 which is true
x < 7 becomes 4 < 7 which is also true
Both inequalities are true, which confirms x = 4 is a solution.
----------
If you wanted, you can think of x > 0 as 0 < x
Then we have 0 < x and x < 7 become 0 < x < 7
Replacing x with 4 has 0 < 4 < 7 as a true statement.
Answer: y=29, x=-3
Step-by-step explanation:
eq. 1: 9x+y=2
9 • -3+y=2
-27+y=2
y=29
eq. 2: -4x-y=-17
4x+y=17
5x=-15
x=-3
3x - 42 = 30
3x = 72
x= 24
