<h3>Answer:  21x+14  (choice A)</h3>

Explanation:

Use the distribution rule to multiply the outer 7 by each term inside

  • 7 times 3x = 21x
  • 7 times 2 = 14

We go from 7(3x+2) to 21x+14

Solve y=-x+2 and y=-2x-1 as a graph, substitution, or elimination?
kotegsom [21]

Answer:

(- 3, 5 )

Step-by-step explanation:

Given the 2 equations

y = - x + 2 → (1)

y = - 2x - 1 → (2)

Using substitution method.

Substitute y = - x + 2 into (2)

- x + 2 = - 2x - 1 ( add 2x to both sides )

x + 2 = - 1 ( subtract 2 from both sides )

x = - 3

Substitute x = - 3 into (1)

y = - (- 3) + 2 = 3 + 2 = 5

Solution is (- 3, 5 )

Take some points

  • 2x+3y<6
  • 3y<-2x+6
  • y<-2/3x+2

As here < sign present line will be dashed and shading should be done below the line

So

  • (1,1)
  • (1,0)
  • (2,0)

A book agent charges 15% to represent an author. If the agent earns $4.5 thousand from a book deal, how much does the author ear
netineya [11]

Answer: $25,500

Step-by-step explanation:

15/100 = 4500/x , we use this proportion to find out how much the entore book deal was.  When you multiply 4500 x 100 and divide by 15, it gives you an answer of 30,000.  30,000 is the value of the book deal.  The agent gets 15% but the entire deal would be worth 100%.  We subtract 15% from 100% to get 85%.  85% is what the author will receive.  85% of 30,000 is $25,500. We find the answer by multiplying 30,000 by 0.15. 0.15 is the decimal equivalent of 15.
