In this question, you're solving the systems of equations.
Solve:
2x + y = 1
3x - y = -6
<em>Since the y's could cancel out, lets solve for x</em>
2x + y = 1
3x - y = -6
-------------------
5x = -5
x = -1
Now, we know that x = -1, lets find y by plugging in -1 to x in any of the equations.
2(-1) + y = 1
-2 + y = 1
<em>Add 2 to both sides</em>
y = 3
This means that your answer would be (-1, 3)
Answer:
(-1, 3)
Answer:
x+20 ≤ x²+9
Step-by-step explanation:
the options you gave didnt have any square options, so imma just guess you meant this? if not, let me know.
Answer:
3 : 15pm
Step-by-step explanation:
2 : 25 pm + 50 minutes
2 : 25 pm + (35 minutes + 15 minutes)
(2 : 25 pm + 35 minutes) + 15 minutes
3 : OO pm + 15 minutes = 3 : 15 pm
Answer:
84
Step-by-step explanation:
12*3+6x=4.20(12+x)
36+6x=50.4+4.2x
6x-4.2x=50.4-36
1.8x=14.4
x=14.4/1.8
x=8 pounds of cashews is used.
Proof:
12*3+6*8=4.2(12+8)
36+48=4.2*20
84=84
