Answer:

no solutions

Step-by-step explanation:

-2x+3y=8

 2x-3y=10

We can use elimination to solve for x and y

Add the two equations together

-2x+3y=8

 2x-3y=10

---------------------

0 = 18

Since this is never true, there are no solutions to this system of equations

What is 80 in its simplest form as a fraction?
Ann [662]

I believe the correct given problem is:

“What is 80% in its simplest form as a fraction?”

 

Take note that you missed to place the percent sign which is very important.

 

Now to solve this, 80% when converted to decimal form is 0.80 which means that you have 80 parts per 100 parts. Therefore the fraction form of this would be 80 / 100.

fraction = 80 / 100

However this fraction is not yet the answer because we can still simplify this further. First step in simplifying is to divide both the numerator and denominator by 10 so that we are left with:

8 / 10

Next step is to divide by 2:

4 / 5

 

Now we can see that we can no longer divide this (numbers should be whole number). Therefore the simplest form as a fraction is 4/5

 

Answer:

4/5

You are saving money for a new phone. You must have at least $800 saved up in
NeX [460]

Let number of hours needed to work = x

Multiply number of hours by rate: 15x

Add what you already have saved:

15x + 215

This needs to equal at least 800:

The equation becomes:

15x + 215 >= 800

Solve for x:

15x + 215 >= 800

Subtract 215 from both sides

15x >= 585

Divide both sides by 15

X >= 39

They have to work at least 39 hours.

Consider the image of EFGH for the translation (x, y) → (x – 3, y + 1). What is the ordered pair of F′?
omeli [17]

Answer:

F'(-1,3)

Step-by-step explanation:

The rule for the translation is given as

(x,y)\rightarrow (x-3,y+1)

The coordinates of F are (2,2).

We substitute these coordinates into the translation rule to find the coordinates of F'.

F(2,2)\rightarrow F'(2-3,2+1)

F(2,2)\rightarrow F'(-1,3)
