I hope it did it corrects but It’s 90°
Answer:
Step-by-step explanation:
x=7 would be horizontal and would be 7 units to the right of the origin, y= -2 would be vertical and 2 units down from the origin
The Solution:
Given:
Plan A:
Each text sent or received cost $0.10.
If x=number of texts sent or received in a month, the total cost is:
Plan B:
Users pay a fixed charge of $12 and an additional $0.02 for each text sent or received. So, we have the expression for the total charges as:
Part (a)
Writing the inequality that shows that to use plan A is cheaper than using plan B, we have:
Part (b)
Solving the inequality in part (a) above, we have:
Dividing both sides by 0.08, we have:
Therefore, the correct answer is [option 2]
Answer:
<u>Yes</u>
- (2 · x) + (2 · 7) = 36
- x + 7 = 18
- 2x + 14 = 36
<u>No</u>
- 2x + 7 = 36
- 2(x + 7) = 72
- x + 14 = 36
Step-by-step explanation:
It is appropriate to eliminate parentheses as a first step. This can be done using the distributive property, resulting in either of ...
- 2x +2·7 = 36
- 2x +14 = 36 . . . . . 2·7 evaluated mentally
or by dividing the equation by the factor outside parentheses, resulting in ...
___
Any of the equations other than these represent violations of the equal sign. Something has been done to one side of the equation without the same thing being done to the other side.
