Answer:
(3, - 1 )
Step-by-step explanation:
Given the 2 equations
2x - 3y = 9 → (1)
x + 2y = 1 → (2)
Rearrange (2) expressing x in terms of y by subtracting 2y from both sides
x = 1 - 2y → (3)
Substitute x = 1 - 2y into (1)
2(1 - 2y) - 3y = 9
2 - 4y - 3y = 9
- 7y + 2 = 9 ( subtract 2 from both sides )
- 7y = 7 ( divide both sides by - 7 )
y = - 1
Substitute y = - 1 into (3) for corresponding value of x
x = 1 - 2(- 1) = 1 + 2 = 3
solution is (3, - 1 )
Answer:
The correct option is
The origin is included in the shaded region and the shaded area is below the line.
Step-by-step explanation:
Y>3/2x + 2
Put x=0
Y= 2
(0,2)
Put y=0
X= -4/3
(-4/3,0)

Answer:
12
Step-by-step explanation:
To solve the problem, you have to leave the x alone,
To do so, you have to add 84 on each side
12x = 4x + 96
Then, subtract 4x on each side,
8x = 96
Then divide each side by 8, so
x = 12

Answer: B) 2r = v</h3>
================================================
Explanation:
r = amount of salad Reagan ate
v = amount of salad Olivia ate
"Olivia ate twice as much as Reagan", meaning
amount Olivia ate = 2*(amount Reagan ate)
v = 2*r
v = 2r
2r = v
Answer:
75
Step-by-step explanation:
We line up the tens place of 33 and 42 as well as the ones place so that it looks like:
33
+42
--------
Then we add first the ones, which is 3 + 2 for 5. Then we add the tens together, 3 + 4 is 7. We put the five first since its in the ones place and the 7 second since its in the tens place for 75.
