Answer:
<h2>
w = -8</h2>
Step-by-step explanation:
Given the equation solved by Ernesto expressed as 
, the extraneous solution obtained by Ernesto is shown below;
Hence, the extraneous solution that Ernesto obtained is w = -8
A 150% markup of a picture frame that costs 2.99 would cost : 4.49
To solve this, create an equation that follows 45% of a value is 18. This would look like x*.45=18. Now, solve for x, x*.45=18, divide by .45, x=18/.45=40, making your value 40. To check, plug in your value to the equation 40*.45=18 and see if it stays true.
.08 x .04 is the right answer
Answer:
The correct statment is B.
Step-by-step explanation:
A. is not correct: y = 2.4(30) - 1.8 does not equal 70...
<u>B. Is correct because the slope is 2.4 From the equation</u>
C. is not correct because the points have no 2.4 (maybe 2.2)? difference.
D. is not correct. the correlation isn't positive.
