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: 1.92 x 10^8
Step-by-step explanation:
Answer:
A
Step-by-step explanation:
Let's try choice A.
y = -5x-4
(10, -52)
-52 = -5(10)-4
-52 = -50-4
-52= -54
-52 is not equal to -54, so A is the answer.
11.
-8y=24
We want to isolate y to get the value of 1y. Divide both sides by -8
y= -3
Final answer: y=-3
12.
This is the associative property of addition (D).
It states that when adding three terms, the sum is equal no matter the grouping (parentheses).
