- 8 ( x + 2 ) + 5x = - 4
Start by distributing.....
- 8 x - 16 + 5x = - 4
Combine like terms.....
- 3 x - 16 = - 4
Add 16 to both sides.....
- 3x = 12
Divide both sides by -3 to get x by its self.....
x = - 4 is the answer
Answer:
The answer will be y=2x-1
Step-by-step explanation:
With the graph we are able to use the formula rise/run, which means we count down from the top point, and then over, and then divide.
Going down is 4 points, and over is 2.
4/2 is 2.
This leaves us with two answers. With this information, we look at the direction the graph is going, it is going upwards, making it positive. Which means that your answer is the first one. Plus the line goes through -1.
Thank you, if you need any more help let me know.
Answer:
The answer is x= 9.9
Step-by-step explanation:
3= x/3.3
Switch sides:
x/3.3 = 3
Multiply both sides by 3.3:
3.3x/3.3 = 3* 3.3
Simplify:
x= 9.9
Hope this helped :)
For the answer to the question above,
since the only variable used to determine earnings is the number of doors knocked, you can eliminate options 1 and 3 as they are based on the number of books sold, which is not a part of the equation.
<span>That leaves the only options being the increase of $20 or $50 for each door knocked. As the x value we multiply by 20, the correct answer is #2, her earnings will increase by $20 for each door knocked. </span>
<span>You can also check this by plugging in values: </span>
<span>Assume 10 doors are knocked: </span>
<span>E(10) = 20(10)-50 = 200-50 = 150 </span>
<span>Assume 11 doors (1 more door) is knocked: </span>
<span>E(11) = 20(11)-50 = 220-50 = 170 </span>
<span>The increase from 1 door is $20.</span>
