Answer: On this graph, you could label integer points (0,-4) which is the vertex, and (-2, 4) and (2,4)
Step-by-step explanation:
The shape is a parabola opening upwards. The x-intercepts are (-1.414,0) and (1.414, 0) The positive and negative values of √2
The domain (x-values from left to right) All real numbers (-∞, ∞ )
The range (y-values bottom to top) All real numbers greater than or equal to -4 [-4, ∞ )
8x² + 64x = 0
8x(x + 8) = 0
8x = 0 or x + 8 = 0
x = 0 or x = -8
Answer: x = 0 or x = -8
Answer:
40
Step-by-step explanation:
First we need to subtract the 50 students enrolled in English class.
150 - 50 = 100
Next, let's add the mathematics students and the physics students.
80 + 60 = 140
Then we subtract the total amount of mathematics and physics students by the total number of students.
140 - 100 = 40
Therefore, there are 40 students who take both mathematics and physics.
