10 + 6x = 15 + 9x – 3x

Mathematics
1 answer:
ollegr [7]3 years ago
3 0

Answer:

No solution

Step-by-step explanation:

Step 1: Write equation

10 + 6x = 15 + 9x - 3x

Step 2: Solve for <em>x</em>

  1. Combine like terms: 10 + 6x = 15 + 6x
  2. Subtract 6x on both sides: 10 ≠ 15

Here, we see that <em>x</em> would equal no solutions. You can also think of it as parallel lines; they have the same slope but different y-intercepts, so they will never intersect.

Please solve #13-14
Serga [27]

Answer:

XZ = 44

KQ = 24

Step-by-step explanation:

XH is half of XZ, and XH is 22x so two times 22x will give you XZ.

XH times two equation - 2(22x)

XZ equation - 43x + 1

Set them equal

2(22x) = 43x + 1

44x = 43x + 1

x = 1

Put x in equation XZ

43(1) + 1 = 44

Please help on this question.
Sonbull [250]

Answer:

C

Step-by-step explanation:

\frac{ - 20 {x}^{2}  + 14x + 12}{5x - 6}  \\  \\  =   \frac{- (20 {x}^{2}   - 14x - 12)}{5x - 6}  \\  \\ =   \frac{ - (5x - 6)(4x + 2)}{5x - 6}  \\  \\  =  - (4x + 2 ) \\  =  - 4x - 2

Domain:

g(x) ≠ 0

5x - 6 = 0 \\ 5x = 6 \\  \\ x =  \frac{6}{5}

All real numbers ≠ 6/5

-5x+y+-2<br> -3x+6y= -12<br><br> solve for x and y
shtirl [24]

Step-by-step explanation:

y+6y-2= -12

7y-2 = -12-2

7y. = -14

7y/7y = -14/7y

y = -2

-5x+-3x

-8x-2-2= -12

-8x -4= -12-4

-8x = -16

-8x/-8x = -16/-8x

x = -2

A seven digit phone number consists of a three-digit prefix followed
Svetlanka [38]

10000 different phone numbers are possible for a  particular prefix if repetion of digits is allowed

5040 different phone numbers are possible for a  particular prefix if repetion of digits is not allowed

<em><u>Solution:</u></em>

Given that,

A seven digit phone number consists of a three-digit prefix followed  by four digits

We have to find the different phone numbers are possible for a  particular prefix

For a paricualr prefix, there are four digits

Total numbers from 0 to 9 are 10

Therefore,

Different ways for phone number for particular prefix:

If repetition is allowed:

Different ways = 10 x 10 x 10 x 10 = 10000 ways

If repetition is not allowed then:

Different ways = 10 x 9 x 8 x 7 = 5040 ways
