The answer for this is 1.39
Answer:
Step-by-step explanation:
The given expression is the sum of three non-negative expressions. The square is zero or positive, the absolute value is zero or positive.
<u>Since the sum is zero, each of the expressions should equal zero:</u>
- 2x + 5y - 7 = 0
- 4x - 2y = 0
- 5x - 1/2y + k = 0
<u>From the first 2 equations we get:</u>
- 4x = 2y ⇒ y = 2x
- 2x + 5(2x) = 7
- 12x = 7
- x = 7/12
<u>Find the value of y:</u>
<u>Substitute the values into third equation and find the value of k:</u>
- 5x - 1/2y + k = 0
- 5*7/12 - 1/2(7/6) + k = 0
- 35/12 - 7/12 = - k
- 28/12 = - k
- 7/3 = - k
- k = - 7/3
2/3*5/4
2*5/3*4
10/3*5
10/12 simplify
5/6
Answer: True: The graph of y=3x²-3 opens up
Graph the parabola using the direction, vertex, focus, and axis of symmetry.
Direction: Opens Up
Vertex: (0,−3)(0,-3)
Focus: (0,−35/12)
Axis of Symmetry: x=0
Directrix: y=−37/12
X={-2, -1, 0, 1, 2}
Y={9, 0, -3, 0, 9

Answer:
x=-8 then x times y coulum = x coulum answer same for if y=-9 then times x coulum =y coulum answers if y=x+5 solve for x be making y=0
Step-by-step explanation:
Start by piking the equations you want to use and put them on the lines below the box the take and put that into a table with that if it’s a x then you start with the y coulum and put -2,-1,0,1,2 ok then from their if you know what x is you times it by the y coulum and contiue to do that with all the x integers this is the same for the y integers except it’s switched. If you still don’t understand I suggest asking your teacher for help and be honest with them that you didn’t understand it.
