Answer:

Slope: -11/10

Step-by-step explanation:

always do y2 - y1/x2 - x1

12 - 1 / -19 + 9 = -11/10

Answer: 21/-20

Why?
To find skip you do the difference of Y/ the difference of x. So...
12+9/ -19-1 = 21/-20

Hope this helps :D

What is the algebraic rule?? And how do you find out what algebraic rule on a graph is (x,y)to (x,y+10)??? I know how to find ba

Arlecino [84]

Answer:

(x, y) ⇒ (-x, y)

Step-by-step explanation:

When you're looking for a rule that transforms one figure to the other, the first step is to look at the figures. You want to identify their orientation (order of vertices) and the relative locations of corresponding vertices.

Here, vertices VWX are in clockwise order. The corresponding vertices V'W'X' are in counterclockwise order. For that to happen, there must be a reflection involved.

The y-axis goes through the midpoints of VV', WW' and XX'. This means the y-axis is the line of reflection. The coordinates of V'W'X' have the same y-values as their originals, but their x-values have changed sign.

The algebraic rule for these two figures is ...

(x, y) ⇒ (-x, y) . . . . . . reflection over y-axis; sign of x changes

Additional comment

No rotation is involved here.

The rule (x, y) ⇒ (x, y+10) means the y-coordinate has had 10 added to it. That causes a translation upward by 10 units. This is the algebraic rule.

(a+b)²=d Isolate a on one side

PilotLPTM [1.2K]

Answer:

a=sqrt(d)-b, a=-sqrt(d)-b

Step-by-step explanation:

(a+b)^2=d

(a+b)=sqrt(d)

a+b=sqrt(d), a+b=-sqrt(d)

a=sqrt(d)-b, a=-sqrt(d)-b

Three brothers share 2 sandwiches equally how much of a sandwich does each brother get?

Valentin [98]

Answer:
Each brother gets $\frac{2}{3}$ of a sandwich

Explanation:
We know that the total number of sandwiches is 2 and that the number of brothers is 3.

Since we are given that the sandwiches will be divided equally among the three brothers, this means that each will get an equal share.

Therefore, to get the share of each, we will simply divide the number of sandwiches by the number of brothers as follows:
each one will get = $\frac{# sandwiches}{# brothers}$ = $\frac{2}{3}$ of a sandwich

Hope this helps :)
