Mathematics
1 answer:
Aleksandr [31]3 years ago

Answer:

x =3

Step-by-step explanation:

3(4x + 4) = 2(5x+9) - 12

First step is to open the brackets by multiplying. It becomes

3×4x + 3×4 = 2×5x + 2×9 -12

12x + 12 = 10x + 18 - 12

Collecting like terms on the right hand side and left hand side of the equation, it becomes

12x -10x = 18 -12 -12

2x = -6

Negative sign on the right hand side of the equation overwhelms the positive sign on left hand side of the equation. It becomes

2x = -6

x = -6/2 = -3

Checking

3(4×-3 + 4) = 2(5×-3+9) - 12

-24 = -12-12= -24

So x = -3

I need to find the slope, vertical intercept and horizontal intercept of these 3 linear functions:
Bumek [7]
These are in y=mx+b form where m=slope
sometimes b=0

vertical intercept means the y-intercept and the horizonatl intercept is the x intercept so the x intercept is when y=0 and the y intercept is when x=0 so the first one is

y=5x-15
slope=5
y-intercept=-15
x-intercept=3

y=7-x
this can be written as
y=-1x+7
slope=-1
y-intercept=7
x-intercept=7

4x=2y=12
we must get it into slope intercept form
divide the whole thing by 2x=y=12
 we can disregard the 12 and get
2x=y or y=2x+0
slope=2
y-intercept=0
x-intercept=0

I have a car dealership employing 4 mechanics. I received 20 cars to repair today. How
schepotkina [342]

We are given that car dealership employed 4 mechanics. and 20 cars came there.

That means each employee should handle \frac{20}{4} = 5 cars

Which means we need to choose 5 cars from 20 cars first . For that we need to use combinations since order in which car is given to mechanic does not matter.

Hence number of ways =20_{C_{5} } =\frac{20! }{15! * 5!} =  15504 ways of allocating.
