Answer:
y=2x+5 is the answer ALSO CAN WE TALK ABOUT THE FACT THAT MOO975 IS ON THREE QUESTIONS AT THE SAME TIME
Step-by-step explanation:
-4 = y + 3
y = -4x - 3
Solve for Y in the first equation:
-4 = y +3
Subtract 3 from both sides:
y = -7
Now using the addition method:
rewrite the second equation as 4x+y = -3
Multiply y = -7 by - 1 to get -y = 7
Now add the two together:
4x +y = -3
-y =7
4x = 4
Divide each side by 4:
x = 4/4 = 1
Then replace x in one of the equations to solve for y which is -7
X = 1, Y = -7
Answer:
2
Step-by-step explanation:
(2/3)3= 2× 3/3 = 2×1 (since 3/3=1)
=2
Answer: 3p² + q² - 5pq - 10 < 0
<u>Step-by-step explanation:</u>
p² - q² + 2pq < -2p² - 2q² + 7pq + 10
since you didn't specify what to solve for, move everything from the right side to the left side of the inequality symbol using inverse operations.
(p² + 2p²) + (- q² + 2q²) + (2pq - 7pq) + (- 10) < 0
3p² + q² + -5pq + -10 < 0
3p² + q² - 5pq - 10 < 0
