Answer:
The line of symmetry is x=2
Step-by-step explanation:
Given:
We are given a quadratic equation and to find the line of symmetry.
As we know the line of symmetry of parabola passes through the x value of vertex.
If vertex of parabola is (h,k) then equation of line of symmetry x=h
So, first we find the vertex of parabola.
For equation:
For given equation, a=-3 and b=12
Therefore,
Hence, The line of symmetry of given parabola is x=2
B) 5.8 in.
C) 52 in.
D) 80 in.
Answer:
correct answer is A
Step-by-step explanation:
1.5 in
Step-by-step explanation:
-12.6x - 4.9x = -154
-17.5x = -154
17.5x = 154
x = 154/17.5
x =8.8

Answer: Equation for Tina be
Equation for Rita be
Step-by-step explanation:
Since we have given that
Number of hours Rita worked for = r
Number of hours Tina worked for = t
Cost per hour = $ 11
Amount for overtime Rita earned = $32
So, the equation expressing total weekly wage for Tina be
The equation expressing total weekly wage for Rita be
Answer:
42.1
Explanation step-by-step:
Working out the lenght of the blue-dashed line:
SOH
47 is the Hypotenuse.
the blue line is the adjacent.
adjacent= Cos(30) x47
adjacent= 40.7
Working out x :
40.7 is the opposite this time.
x is the adjacent.
x = 40.7/ Tan(44)
x = 42.1
