Answer:
k=1
Step-by-step explanation:
-2k+10=64k-56
66=66k
k=1
Answer:
5.
Step-by-step explanation:
So 5x35 is 175. Divide by 35 and you get 5.
The answer would be letter B. You can see that the price of the demanded products as the time passes by decreases. So the answer is letter B.
To solve this system of equations, since y is already isolated in both equations, you can set the expressions to equal each other to solve for x:
-x + 2 = - 5x - 6
-x + 5x = -6 - 2
4x = -8
x = -2
Now that we have x, we can substitute it into one of the equations to find y:
y = -(-2) + 2
y = 2 + 2
y = 4
The last step is to substitute both values into both equations to see if they are correct:
4 = -(-2) + 2 --> 4 = 2 + 2 <--True
4 = -5(-2) - 6 --> 4 = 10 - 6 <--True
Answer:
x = -2
y = 4
