Answer:

f=1

Step-by-step explanation:

To solve for f, we need to get f by itself. To do this, we need to move all the numbers to one side of the equation, and all the variables to the other

-f+2+4f=8-3f

Combine like terms

(-f+4f) +2=8-3f

3f+2=8-3f

Add 3f to both sides

3f+3f+2=8-3f+3f

6f+2=8

Subtract 2 from both sides

6f+2-2=8-2

6f=6

Now all the numbers are one sides, and the variables are on the other. f is still not completely by itself, it is still being multiplied by 6. To reverse this, divide both sides by 5

6f/6= 6/6

f=1

Answer:

f = 1

Step-by-step explanation:

-f + 2 + 4f = 8 - 3f

-f + 4f + 3f = 8 - 2

6f = 6

f = 6/6

f = 1

Hope it helps!!

If three times the larger of two numbers is four times the smaller and the difference between the numbers is 8, then the larger

MaRussiya [10]

Answer:

Larger number = 32

Step-by-step explanation:

Smaller number = x

Larger number = y

y - x = 8 -----------(I)

3y = 4x ---------------(II)

3y/4 = x

Plug in x = 3y/4 in equation (I)

$y - \frac{3}{4}y = 8\\\\\frac{4}{4}y - \frac{3}{4}y = 8\\\\\frac{1}{4}y = 8\\$

y = 8*4

y = 32

Plug in y = 32 in equation (II)

3y = 4x

3*32 = 4x

4x = 3*32

x = $\frac{3*32}{4}$

x = 3 *8

x = 24

Help please will mark brainliest

natima [27]

Answer:

A table that has (0,0), (-1,1), (-4, 2) and undefined for any positive x value

Step-by-step explanation:

Reflecting across the y axis just changes the x values, it makes them negative. so $\sqrt{x}$ has points (0,0), (1,1), (4, 2) and so on. reflecting over the y axis makes them(0,0), (-1,1), (-4, 2) and again so on.

Also good to mention in $\sqrt{x}$ negative x values are undefined, so flipped over the y axis positive x values are undefined.

As for the answer it doesn't look like any of those shown. The first one is close, but the x values would need to swap their signs.
