The table of solutions for the given equation (y = -2x²) include the following:
<u>x y_</u>
-2 -8
-1 -2
0 -0
1 -2
2 -8
Also, a graph of the solution of this equation (y = -2x²) has been plotted in the image attached below.
<h3>How to determine the solution?</h3>
In order to determine the valid and true solutions to the given quadratic equation, we would have to substitute the values of contained in the table into the quadratic equations as follows;
At x = -2, the value of point y is as follows:
y = -2x²
y = -2(-2)²
y = -2 × 4
y = -8
At x = -1, the value of point y is as follows:
y = -2x²
y = -2(-1)²
y = -2 × 1
y = -2
At x = 0, the value of point y is as follows:
y = -2x²
y = -2(0)²
y = -2 × 0
y = 0
At x = 1, the value of point y is as follows:
y = -2x²
y = -2(1)²
y = -2 × 1
y = -2
At x = 2, the value of point y is as follows:
y = -2x²
y = -2(2)²
y = -2 × 4
y = -8
In conclusion, we can logically deduce that the graph of this quadratic equation forms a downward parabola.

Answer:
The answer is: y = -4
Step-by-step explanation:
You are trying to get the value of y.
y + 8 - 4 = 0
y + 8 - 4 + 4 = 0 + 4
y + 8 - 8 = 4 - 8
y = -4

Answer:
The angle measure for the bottom two angles in order for the triangle to be classified as an isosceles triangle are 30 degrees each
Explanation:
An isosceles triangle has two of its angles equal.
Given that one angle is 120 degrees, assuming the remaining angles are equal, since the sum of the angles in a triangle is 180 degrees, we have:
120 + x + x = 180
120 + 2x = 180
2x = 180 - 120 = 60
x = 60/2 = 30
Each of the remaining angles measure 30 degrees
Answer:
0.3 L
Step-by-step explanation:
3 L / 10 students = 3/10 = 0.3 Liters per student
Hi there!

I believe your answer is:
"Add 4 to both sides, and then divide by 2. The solution is x = 12."

Here’s why:
⸻⸻⸻⸻
- To solve for 'x', we would have to use inverse operations.
- We would first have to add four to both sides to undo the negative four. Addition is the opposite of subtraction.
- We would then divide by 2 to isolate 'x'. Division is the opposite of multiplication.
