Answer:

y = 17

Step-by-step explanation:

We have five values : 2 , 5 , 7 , y , 9

and the mean = 8

this means :

\frac{2+5+7+y+9}{5} =8\\\\then\\\\23+y = 8*5\\\\then\\\\y = 40 - 23\\\\then\\\\y=17

Verification: (2+5+7+17+9)÷5 = 8

B) If A (-3, 2) is translated by
Alona [7]

Answer:

A'(-6,4)

Step-by-step explanation:

A transformation of  (x, y) → (x-3, y + 2)  means:

  • x coordinate gets translated 3 units left [we subtract 3 from original x coordinate]
  • y coordinate gets translated 2 units up [we add 2 to original y coordinate]

The original x coordinate is -3 so we subtract 3 from it to get:

New x = -3 -3 = -6

The original y coordinate is 2 so we add 2 to get:

New y = 2 + 2 = 4

So A' is

A'(-6,4)

15 points!! Please help! please explain how you got you answers
Lynna [10]

We observe that a line will pass through 3 points, but to find a slope we only need two.

We see that it passes through points (assuming the scale of graph is 1 : 1) P_1(x_1,y_1)=P_1(0,1) and P_2(x_2,y_2)=P_2(2,-1).

We can use slope formula that applies for any line and produce the same slope for any two different points on the line

m=\dfrac{\Delta{y}}{\Delta{x}}=\dfrac{y_2-y_1}{x_2-x_1}=\dfrac{-1-1}{2-0}=-1

So the slope is -1 also it intersects y-axis at n=1 so the general form of the linear function is

f(x)=mx+n

That is in your case

\boxed{f(x)=-x+1}

Hope this helps.

How do you turn decimals into fractions?
RoseWind [281]
To turn decimals into fractions all you have to do is say it in your head!
For example: The decimal 0.284 is two hundred eighty four thousandths and that would equal to 284/1000
