Answer:
Step-by-step explanation:
<u>Given functions f(x) and g(x). f(x) is:</u>
<u>Converted into vertex form, it is:</u>
<u>g(x) has vertex at (-2, -14), it's vertex form is:</u>
Comparing f(x) and g(x) we see both have same x- coordinate of the vertex (x = -2).
Both have positive leading factors, therefore the vertex is their minimum point.
Function f(x) has vertex above the x-axis as y-coordinate of the vertex is positive. Hence no intersection with x-axis.
Function g(x) has negative y-coordinate of the vertex, so it has two intersections with x-axis.
Correct choice is A
The answer is option 6! hope it helps
Answer:
x = will be the expression.
Step-by-step explanation:
In this question an expression has been given which represents the relation between average cost C and number of T shirts (x) manufactured.
We have to solve this expression for the value of x (number of T-shirts) in terms of C.
C = 5x + 410x
C = 415x
x =
Therefore, x = will be expression showing the number of T-shirts in terms of average cost.
Answer:
3x - y =13
Step-by-step explanation:
- y - y1 = m(x - x1)
- y - 2 = m(x - 5)
- distribute
- y - 2 = 3x - 15
- jump -2 across the equal sign and change the sign
- y = 3x - 15 + 2
- combine like terms
- y = 3x - 13
- use this equation to find the standard form
- y = 3x - 13
- jump the x and change the sign
- -3x + y = -13
- x must be positive, so change the sign of everything
- 3x - y = 13
