Anyone know the answer?

Answer:

Step-by-step explanation:

This is of the form

f(x)=a(x-h)^2+k

where h and k are the coordinates of the vertex, and the values that tell us the translation of the parent graph from its starting point (which is always the origin).  The 2 out front, the a value, tells us that the graph of this parabola is a bit slimmer than the parent graph, but does nothing to its translation (or movement).  It does, however, tell us which way the parabola opens.  Because the parabola opens upwards, the 2 is positive. The h value tells us our side to side movement.  The "(x - " part is very important because it doesn't change.  If we have (x - 2), then it is understood to be (x - (2)) which is movement 2 units to the right (because positive numbers move right or up, while negative numbers move left or down).  If we have (x + 2), then it is understood to be (x - (-2)) which is movement 2 units to the left.  Because our parabola is shifted 2 units to the right, it reflects (x - 2) squared.  It is shifted up 2 so the k value is a +2.  The equation for this parabola could be B only.

The what value complete the square for the expression x squared plus 16x
Troyanec [42]
Take the coefficient of the x-term, half it, then square that. add this to both sides

x² + 16x. coefficient of x is 16. half of 16 is 8. 8²=64

x² + 16x + 64 =64. this is your answer but to continue

x² + 16x + 64 = 64
(x+8)² = 64
x+8 = ✓64
x+ 8 = ±8
x = 0 or -16

At the corner store near Billy’s
nikklg [1K]

Answer:

d = 0.0175n    ---> required equation

Billy can buy 285.714 gram nut with $5

Step-by-step explanation:

cost of 100g loose nut = $1.75

dividing LHS and RHS by 100

cost of 100/100g loose nut = $1.75

Thus, cost of 1 gm loose nut = $0.0175

let the weight of loose nut be n gm

Multiplying LHS and RHS by n

cost of x g loose nut = $0.0175*n =  $0.0175n

It is given that Billy spent d dollars to buy n gm nuts

thus,

d = 0.0175n    ---> required equation

________________________________________________

He spent $5 to buy nuts

substituting value of d as 5 we have

0.0175n = 5

=>n = 5/0.0175 = 285.714

Thus, Billy can buy 285.714 gram nut with $5.

4000 / 328.70 = 12.17 weeks

 so it would take her 13 weeks
