3

3(f+g) = (y) 3
--------

f + g =3y

f - f + g = 3y - f

g = y - f

Find the Slope and Y- intercept of the line

lara [203]

Find slope by calculating rise over run (can pick whatever points are easiest for you). I'm choosing (0,2) and (-3,0)

(0-2)/(-3-0)
(-2)/(-3)
2/3

Slope=2/3

Y intercept is the value of y when x is 0. We can look to see the y intercept is 2.

Final answer: D

A wooden plank is cut into three pieces. The ratio of the length of the pieces of wood is 6:10:12. If the length of the original

iren2701 [21]

Answer:

290 centimetres

Step-by-step explanation:

The ratio of the length of the pieces of wood is 6 : 10 : 12.

We have to find the total ratio first:

6 + 10 + 12 = 28

The longer piece of wood has ratio 10.

The length of the original wooden plank is 812 centimetres, therefore, the length of the longer piece of wood is:

10/28 * 812 = 290 centimetres

A man receives an annual increase of #30000 and after a period of 10 years service, the man has the salary of #1014. Find his in

Paladinen [302]

I think you intended writing #30 as his pay rise instead of #30000. I solved the problem using #30 as his annual pay rise.

Answer:

The man's initial salary was #714

Step-by-step explanation:

Extracting the key information from the question:

*** A man got a pay raise for 10 years.

*** His current salary is #1,014

*** He gets a pay raise of #30 annually.

*** We are simply required to calculate his initial salary before he started receiving pay rise.

Now, To calculate his initial salary before he started receiving pay rise, let us denote that initial salary that we are currently unaware of by "a".

Since his salary as at today is #1,014 and he has also received this pay rise of #30 for 10 years, we can calculate his initial salary before he started receiving pay rise every year with the following equation:

a + 30(10) = 1014

That is -

Initial salary + [pay rise × number of years] = current salary.

a + 30(10) = 1,014

a + 300 = 1014

a = 1014 - 300

a = #714

Therefore the man's initial salary was #714
