Hope I helped!
Best regards!!
1) 2x+4y=10
3x+5y=14 .
find d2, dx2, and dy
2) Solve the system of equations algebraically and show your work.
2x + 3y = 12
2x - y = 4
3) Which of the ordered pairs (5,5),(5,0) and (-3,2) can be found in the shaded solution area for the system of inequalities below? (The ordered pair must be in the double shaded region or it is not a solution of the system.)
x+2y<6
2x+y > or equal too 9 so yea hoped this helped
Answer:
r = 7
Step-by-step explanation:
Given
r + 15 = 4r - 6 ( subtract 4r from both sides )
- 3r + 15 = - 6 ( subtract 15 from both sides )
- 3r = - 21 ( divide both sides by - 3 )
r = 7
Answer:
its A.
Step-by-step explanation:
When you write that equation, you get 3x^2+6=81.
Solving for x:
Subtract by 6 on both sides of the equation to get 3x^2=75.
Then, divide by 3 on both sides of the equation to get x^2=25.
Finally, do the square root on both sides of the equation to get x=5.
The number is 5.
