Answer:

C. None of the above

Step-by-step explanation:

You can get the equivalent expression by simplifying the expression above.

  • 5+(-3)(6x-5)
  • 5+ (-18x+15)
  • 5-18x+15
  • -18x+20

-18x+20 is not the same with 18x-20, therefore A is not a correct answer.

For example, the value of x is 2.

  • -18(2) + 20 = ?                    
  • -36 + 20 = ?
  • -16
  • 18(2) - 20 =?
  • 36 - 20 = ?
  • 16

<em>-16 and 16 are not the same</em>

8-1(x-y)=-3x+5 in standard form
pogonyaev
Standard form is
ax+by=c
get all x and y on one side

first distribute
-1(x-y)=-x+y

now weh have
8-x+y=-3x+5
add 3x to both sides
8+2x+y=5
minus 8 from both sides
2x+y=-3

Imagine that you are given two linear equations in slope-intercept form. You
Digiron [165]

Answer:

No solution.

Step-by-step explanation:

When two lines have the same slope but different y-intercepts, they are parallel.  Parallel lines never intersect, and therefore there is no solution.

Without solving, NO SOLUTION describes which equation?
CaHeK987 [17]

Answer:

The equation 'y = y + 1' represents NO SOLUTION.

Hence, option 'C' is true.

Step-by-step explanation:

a)

6a = 9a

subtract 9a from both sides

6a - 9a = 9a - 9a

-3a = 0

divide both sides by -3

-3a / -3 = 0/-3

Simplify

a = 0

b)

5x = 28

divide both sides by 5

5x/5 = 28/5

x = 28/5

c)

y = y + 1

subtract y from both sides

y - y = y+1-y

0 = 1

These sides are not equal, so

NO SOLUTION!

d)

y + 5 = 12

subtract 5 from both sides

y + 5 - 5 = 12 - 5

y = 7

Conclusion:

Therefore, the equation 'y = y + 1' represents NO SOLUTION.

Hence, option 'C' is true.

Delvig [45]
First, find how many flowers are in 4 arrangements: 10*4=40

You can set this up as a proportion:
²/₁₀ = x/₄₀



You can also just multiply 2 daisies by 4 arrangements.
