Answers

Answer 1

Answer:

Yo sup??

y=3x+12

y-12=3x

x=y/3 - 4

f(y)=y/3 - 4

f(x)=x/3 - 4

where f(x) is the inverse of y.

Hope this helps

What is the greatest common factor of 35 and 63

Answers

The greatest common factor of 35 and 63 is,

⇒ 7

We have to given that;

Find the greatest common factor of 35 and 63.

Now, We can find LCM of number,

⇒ 35 = 7 × 5

⇒ 63 = 7 × 3 × 3

We know that;

The highest number that divides exactly into two more numbers, is called Greatest common factors.

Therefore, the greatest common factor of 35 and 63 is,

⇒ 7

Answers

1 and 3 have the same angle and 2 and 4 have the same angle. Since we know what 1 is we know what 3 is, add them together then subtract that from 360 = 148. To figure out the angles of 2 and 4 divide 148 by 2 = 74. 1 and 3 are 106 degrees and 2 and 4 are 74 degrees :)

Compare the ratios: 2/5 and 3/4

Answers

First, make your ratios into fractions.
You have 2/5 = 3/4.
Now, in your calculator, divide 2 by 5. You get 0.4
Then in your calculator, divide 3 by 4. You get 0.75
0.4 does not equal 0.75
Therefore, there is no solution/they are not equivalent.

System of Equations

y=x-5
3x+y=7

Solve?

Answers

$\sf{y=x-5}$
$\sf{3x+y=7}$

Lets solve this by substitution.

Lets plug in y=x-5 into 3x+y=7

So:

$\sf{y=x-5}$
$\sf{3x+y=7}$

Plugging it in:

$\sf{3x+(x-5)=7}$

Solve for x by simplifying that:

$\sf{3x+x-5=7}$

$\sf{4x-5=7}$

Add 5 on both sides

$\sf{4x=12}$

Divide by 4 on both sides

$\sf{x=3}$

Now simply plug x=3 back into any equation and solve for y

So:
$\sf{y=x-5}$

$\sf{y=3-5}$

Simplify that:

$\sf{y=-2}$

So we are left with our final answer which is
$\boxed{\bf{(3,-2)}}$

Y=x-5
-y=3x-7
Add them together
0=4x-12
12=4x
X=3
Y=-2

A student completed 1/4 of a workbook in 3/5 hour.He plans to work for 1 more hour at the same rate.What Fraction of the workbook should he expect to complete in 1 hour?

Answers

The fraction of the workbook he should expect to complete in 1 hour is 5/12

How to determine the fraction of work?

The student's rate is given as:

1/4 of a workbook in 3/5 hour.

The rate in this scenario is calculated using:

Rate = Workbook/time

So, we have:

Rate = 1/4 / 3/5

Express as product

Rate = 1/4 * 5/3

Evaluate

Rate = 5/12

This means that she would complete 5/12 of the workbook in 1 hour

Hence, the fraction of the workbook he should expect to complete in 1 hour is 5/12
