How do i do this pls help me
Delvig [45]

Answer:

y =  \frac{1}{7} x + 7

Step-by-step explanation:

x-7y = -49

i) move x to the right-hand side and change its sign

-7y = -49-x

ii) change the signs on both sides of the equation

7y = 49+x

iii) divide both sides of the equation by 7

\frac{7y}{7}  = \frac{49}{7}  +  \frac{x}{7}

y = 7 +  \frac{1}{7}  x

iv) use the commutative property to reorder the terms

* commutative property: a+b = b+a

y =  \frac{1}{7} x + 7

Stella [2.4K]

Let  p represents the number of points scored in n number of games.

So, the graph, the number of games, n is on the horizontal axis and the points scored, p, is on the vertical axis.

After Game 1, the point scored is 14,

so, the first point, P_1, on the graph is

P_1=(1,14)

After Game 5, the point scored is 82,

so, the second point, P_2, on the graph is

P_2=(5,82).

After Game 10, the point scored is 129,

so, the second point, P_2, on the graph is

P_2=(10,129)

First, represent all the three points, P_1, P_2 and P_3, on the graph, then connect P_1- P_2 and P_2 - P_3 as shown in the figure.

If f(x) = 1/2x-14,then f^-1(x)=
Alik [6]

Answer:

f ^-1 (x) = 2x+28

Step-by-step explanation:

f(x) = 1/2x-14

Replace f(x) with y

y = 1/2 x -14

Exchange x and y

x = 1/2 y -14

Solve for y

Add 14 to each side

x+14 = 1/2 y -14+14

x+14 = 1/2 y

Multiply each side by 2

2(x+14)= 1/2 y*2

2x+28 = y

The inverse function is

f ^-1 (x) = 2x+28
