Answer:
1) A = -10, B = -4, distance = 6 units
2) Eqaution: 3(x+4) = 60
Tyler's age: 16 Samantha: 20
3) x < 1
Draw a number line from 1 towards left, with an open circle at x = 0
Step-by-step explanation:
1) A/2 = -5
A = -5×2 = -10
8 = -B/0.5
8×0.5 = -B
B = -4
Distance = -4 - (-10) = -4 + 10 = 6
2) S = 4 + x
3s = 60
3(4 + x) = 60
3S = 60 S = 20
4 + x = 20 x = 16
3) x/2 + ¼ < ¾
x/2 < ¾ - ¼
x/2 < ½
x < 1
Draw a number line going towards left from 1, with an open circle at x=1 because x=1 is not included
The gym teacher has $250 to spend on volleyball equipment. She buys 4 volleyball nets for $28 each. Volleyballs cost $7 each. How many volley balls can she buy
Answer:
she can buy maximum of 19 balls.
Step-by-step explanation:
Let the number of volleyballs be x
we know that
so substituting the values,
The answer is 32. Your welcome
The key features of the graph are:
- Vertex (-2, -1)
- Axis of symmetry x = -2
- y-intercept (0, 3)
- Minimum
- Domain, -∞ < x < ∞
- Range y > = -1
<h3>How to determine the key features?</h3>
The graph has a minimum value at (-2, -1)
This represents the vertex
The x coordinate of the vertex is the axis of symmetry.
So, we have
x = -2
The graph crosses the y-axis at (0, 3)
This represents the y-intercept
The graph opens up.
This means that the vertex is minimum.
The domain is the set of all real number, because the graph extends in both directions on the x-axis without end
While the range is y >= -1, because it has a minimum at this point
