The answer is for this question is 4/5
Answer:
x = -1
y = -3
Step-by-step explanation:
We have two equations:
x + y = −4 (1)
y = 2 * x - 1 (2)
What we will do is substitute (2) in (1) and we are left;
x + 2 * x - 1 = −4
3 * x = -4 + 1
3 * x = -3
x = -3/3
x = -1
Now, to find out and, I replace in (2), like so:
y = 2 * (- 1) - 1
y = -2 -1 =
y = -3
Therefore, the values are:
x = -1
y = -3
Answer:
-1500
Step-by-step explanation:
"descends," means to go down (ascend means to go up), so the number would be negative. The number given is 1500, so we use that, and get -1500.
