Since you do not have a picture, i will give you the steps, and you can see where the differences are at.
6x - 1 = -2x + 9
Note the equal sign. What you do to one side, you do to the other. Isolate the x.
First, add 1 to both sides
6x - 1 (+1) = -2x + 9 (+1)
6x = -2x + 10
Next, add 2x to both sides to isolate the x
6x (+2x) = -2x (+2x) + 10
6x + 2x = 10
8x = 10
Finally, isolate the x by dividing 8 from both sides
8x/8 = 10/8
x = 10/8 (may be where they stopped at, but you can go further)
Simplify. Divide 2 from top and bottom
(10/8)/(2/2) = 5/4
x = 5/4 should be final answer
hope this helps
The y-intercept is 28, while the slope is
I did this by moving the x to left, then dividing everything by 4.
3,153,007 rounded to the nearest 100,000 is 3,200,000.
Answer: -2.6%
Step-by-step explanation:
Percent error is the difference between the measured and known value, and then we divide by the known value, and then multiply by 100%.
Estimated.number = 15.4 grams.
Actual number = 15.8 grams
Percentage error = (Estimated number - Actual number)/Actual number × 100
= (15.4 - 15.8)/15.8 × 100
= -0.4/15.8 × 100
= 0.0253 × 100
= 2.53
= -2.6% approximately
