To solve this question, you need to know the rate in which the money is being spent. First, you know the y-intercept, which is 4000, or the money she owned before spending it. Next, you know, how much she had spent in the duration of 3 months. So, if you substitute those numbers into y=ax+b, it would be 2800=-3a+4000 (or 2800=4000-3a either way it is equivalent) If you solve this, you know that the college freshman is spending her money at a rate of $400 per month. Hope this helps :)
Ok so lets say D= Dog And C=Cat
D+C = 54
D = 8C
<span>
Now, substitute 8C for D in the first equation to get: </span>
<span>8C + C = 54 </span>
<span>Solving for the cat gives us C = 6 </span>
<span>D = 8 x 6 = 48
</span>Dog Weighs 48 Pounds

Answer:
B). (-4, 5)
Step-by-step explanation:
-2x – 3y = -7 | ×2 |
-4x + y = 21 | ×1 |
-4x – 6y = -14
-4x + y = 21
____________ --
-7y = -35
y = -35/-7
y = 5
-4x + y = 21
-4x + 5 = 21
-4x = 21 - 5
-4x = 16
x = 16/-4
x = -4
