Answer:
zeros: -11 , 7
Line of symmetry: x = -2
Step-by-step explanation:
y = 2x² + 8x - 154 = 2*(x² + 4x - 77) = 2*(x+11)(x-7)
y = 0
x = - 11 or x = 7
line of symmetry: x = 1/2 (-11 + 7) = -2
2x² + 8x - 154 = 2*(x² + 4x +4) - 162 = 2 * (x+2)² - 162
vertex (h , k): h = -2 , k = -162
Line of symmetry: x = -2
Answer:
If the company produce and sell 'x' no. of thing-a-ma-bob , then
C(x) = $ (8809 + 2.05x)
R(x) = $ 4.92x
To make a profit the company must produce and sell at least 3070 thing-a-ma-bobs.
Step-by-step explanation:
If the company produces and sells "x" no. of thing-a-ma-bob, then,
the cost function is given by,
C(x) = $ (8809 + 2.05x) ------------------------(1)
The revenue function is given by,
R(x) = $ 4.92x -------------------------------------(2)
If C(x) = R(x), then,
4.92x = 8809 + 2.05x
⇒ 2.87x = 8809
⇒ x = 
⇒ x
3069.34
So, to make a profit the company must produce and sell at least 3070 thing-a-ma-bobs.
Answer:
8 meals x 140 boys =1120 food
140boys +84 boys =224 boys
1120 food ÷224 boys = 5 meals
5meals to supply each boy
SW= MP
RV=DL
LAst one is
AN= KG
this pointed in a differ direction fix it the the same direction as the top one.
like number 1: SW is similar MP because then are similar but just differ letters hope that helps.
