Solution for 1/3*-1/9y=3 equation:
<span>y in (-oo:+oo)

((-1*(1/3))/9)*y = 3 // - 3

((-1*(1/3))/9)*y-3 = 0

((-1/3)/9)*y-3 = 0

-1/27*y-3 = 0 // + 3

-1/27*y = 3 // : -1/27

y = 3/(-1/27)

y = -81

</span><span>y = -81</span>Solution for 2/3*1/5y=9 equation:
<span>y in (-oo:+oo)

((1*(2/3))/5)*y = 9 // - 9

((1*(2/3))/5)*y-9 = 0

((2/3)/5)*y-9 = 0

2/15*y-9 = 0 // + 9

2/15*y = 9 // : 2/15

y = 9/2/15

y = 135/2

y = 135/2

F(x)=x what is the equation of the new function shift 8 units left shift 3 units down
nasty-shy [4]
Think of the equation of a linear function:  
Recall y = mx + b   for vertical shifts, we just add or subtract from 'b' and that will move the line up or down accordingly.. However, for horizontal shifts, we will need to add or subtract from 'x'.  Note that the slope or 'm' stays the same for each type of shift.  

Now that we know how the shifts occur, we might consider a different form of the equation for a linear function:  y = a(x - h) + k  here the 'a' is just our slope, 'k' is our original y intercept, and 'h' will represent the amount of horizontal shift.  

So to get the desired transformations of a horizontal shift to the left of 8 and a vertical shift of down 3 from our original function y = x, we can make the following changes:   y = (x + 8) - 3  Now you might be confused with how we got the 'x + 8'..   Let's consider values of 'h'.  For positive values of h, the result will be a shift to the right and for negative values of h the result will be a shift to the left.  So since we want a shift to the left we need to use a '-8' and when we substitute that into our new form, y = (x - h) + k you can see the sign change.  

Now we can simplify of course and get the final equation: y = x + 5 or in function form f(x) = x + 5

42 + 6 for t = 12.<br> write the steps to evaluate the equation please. ☜(⌒▽⌒)☞
Kazeer [188]

Answer:

substitute 12 where it says t in the equation. So first step is to divide 12 by 6 and that = 2 and then add that to 42 which = 44.

Bradley has 64 1-inch cubic blocks.He uses all the blocks to build a rectangular prism that is 2 inches high and 2 inches wide.H
Lynna [10]

Answer:

The length of the rectangular prism is 16\ in

Step-by-step explanation:

step 1

Find the volume of the 64 1-inch cubic blocks

The volume of one cubic block is

V=(1)^{3}=1\ in^{3}

so

the volume of 64 cubic blocks is

V=64(1)=64\ in^{3}

step 2

Find the length of the rectangular prism

The volume of the rectangular prism is equal to

V=LWH

we have

V=64\ in^{3}

W=2\ in

H=2\ in

substitute and solve for L

64=L(2)(2)

64=4L

L=64/4=16\ in

What is the awnser to this The Hernandez family orders 3 large pizzas. They cut the pizzas so that each pizza has the same numbe
Rudiy27

The two true statements are the second statement (both lines contain the point (0,0)) and the fourth statement (If the Wilson family buys 3 pizzas, they will get more slices than the Hernandez family).

<h3>Which is the correct statement?</h3>

First, we know that the Hernandez family orders 3 large pizzas, such that they cut each pizza in the same number of slices, getting a total of 24 slices.

Then the number of slices that they get for each pizza is:

24/3 = 8

So from each large pizza, they get 8 slices.

So the relation between the number of pizzas bought (x) and the number of slices (y) is:

y = 8*x

In the other hand for the Wilson family we have the relation:

y = 10*x

Where y and x are the same ones as the defined above.

Then the true statements are:

<em>"If the Wilson family ordered 3 large pizzas from the same restaurant as the Hernandez family, they would have more slices than the Hernandez family after each family cut their pizzas into slices."</em>

This is true because Wilson family cuts each pizza in 10 slices, while the Hernandez family cuts each pizza in 8 slices.

<em>"For each family, a graph of the relationship between number of pizzas, x, and number of slices, y, goes through the point (0, 0) and is a straight line."</em>

The point (0, 0) means that if they buy 0 pizzas, they get 0 slices, which is true, so both relations contain this point.
