Me i need to answer this before october for each table, identify the independent and dependent variables. represent the relationship using words, an equation, and a graph. number of chairs painted, p | paint left (oz), l 0 | 128 1 | 98 2 | 68 3 | 38 number of snacks purchases, s | total cost ,c 0 | $18 1 | $21 2 | $24 3 | $27 number of flights of stairs climbed, n| 0 | 1 | 2| 3 | elevation(ft above sea level),e |311|326|341|256| me  & you

ANSWER TO QUESTION 7

Independent Variable: Number of Chairs Painted(p)

Dependent Variable: Paint Left(L)

To represent the relationship using a graph, we draw two perpendicular axis, wth Number of Chairs Painted(p) on the horizontal axis, and Paint Left(L) on the vertical axis.

Then we plot the points

, , , .

Using a straight edge, we draw a straight line through the points as shown in the diagram attached.

From the graph the slope is given by

and the y-intercept is

The equation is given by

That is

In words, Paint level is reducing at a rate of oz

ANSWER TO QUESTION 8

Independent Variable: Number of snacks purchased(s)

Dependent Variable: Total Cost(c)

To represent the relationship using a graph, we draw two perpendicular axis, with Number of snacks purchased(s) on the horizontal axis, and Total Cost(c) on the vertical axis.

Then we plot the points

, , , .

Using a straight edge, we draw a straight line through the points as shown in the diagram attached.

From the graph the slope is given by

and the y-intercept is

The equation is given by

That is

In words, the Total cost increases is reducing at a unit rate of

ANSWER TO QUESTION 9

Independent Variable: Number of flight of stairs climbed(n)

Dependent Variable:Elevation (ft above sea level),E

To represent the relationship using a graph, we draw two perpendicular axis, with Number of flight of stairs climbed(n) on the horizontal axis, and Elevation (ft above sea level),(E) on the vertical axis.

Then we plot the points

, , , .

Using a straight edge, we draw a straight line through the points as shown in the diagram attached.

From the graph the slope is given by

and the y-intercept is

The equation is given by

That is

In words, the unit rate of rising above sea level is

fist on the left goes with the third on the right. second on the left goes with the fourth on the right. third on the left goes with the second on the right. the fourth on the left goes with first on the right

step-by-step explanation:

f(x)=2x^2 -1 

translation is a function transformation that transform the function in a way of translating. by translating the function its graph is moved  up an down. moving the function f(x) 2 units to the left will be the new function g(x) with the equation: g(x)=f(x+2)=2(x+2)^2 -1
