Answer:

-1/2.

Step-by-step explanation:

Slope = rise / run

= (1 - -7) / (-1 -3)

= 8/-4

= -1/2.

Answer:

2

Step-by-step explanation:

line is passing through ( 3, -7) and ( -1, 1)

therefore, we take,

x1=3,

x2 =-1

y1 = -7

y2 = 1

let, S = y2- y1 / x2 - x1

now put the value,

S = 1 - ( -7 ) / (-1 ) - 3

S = 8 / 4

S = 2

therefore, slope of line is 2

If g(x)= 3x+1, evaluate g(-2)
seropon [69]

Hey there!

G(x) = 3x + 1

G(-2)

They just ask you to insert the value of -2 instead of x

= (-2)(3) + 1

G(-2)= -5

Match the real-world problem to its constant of proportionality.
OleMash [197]

Answer:

6.12

1.39

4.12

12

Step-by-step explanation:

If y ∝ x, then y = kx.

So, the constant of proportionality is given by k = \frac{y}{x}

Case 1:

$18.36 for 3 pizzas

Therefore, the constant of proportionality is \frac{18.36}{3} = 6.12

Case 2:

$4.17 for 3 pounds of bananas.

Hence, the constant of proportionality is \frac{4.17}{3} = 1.39

Case 3:

$16.48 for 4 pounds of potatoes.

Hence, the constant of proportionality is \frac{16.48}{4} = 4.12

Case 4:

2 cups of flour to make 24 cookies.

Hence, the constant of proportionality is \frac{24}{2} = 12 (Answer)

Let f(X)=3√x
SOVA2 [1]

g(x) = 3√(x-5) -1

The process of altering a graph to produce a different version of the preceding graph is known as graph transformation. The graphs can be moved about the x-y plane or translated. They may also be stretched, or they may undergo a mix of these changes.

Horizontal stretching: It means the graph is elongated or shrink in x direction.

Vertical stretching : It means the graph is elongated or shrink in y direction

Vertical translation : It means moving the base of the graph in y direction

Horizontal translation : It means moving the base of the graph in x direction

According to rules of transformation f(x)+c shift c units up and f(x)-c shift c units down.

Therefore, in order to  move the graph down 1 units, we need to subtract given function by 1 , we get

g(x) = 3√x -1

According to rules of transformation f(x+c) shift c units left and f(x-c ) shift c units right.

Therefore, in order to  move the graph left by 5 units, we need to add given function by 5 , we get

g(x) = 3√(x-5) -1
