What's x and y for x=1+y and 2y+x=10

2 answers:

Substitute the value of x in equation 2. Then you'll get y=3. Then again substitute the value of y in x=1+y, you'll get x=4

Y=3,x=4
You plug in 1+y for x in the other equation so it becomes 2y+1+y=10
Then, you combine the 2y and y to make 3y so its 3y+1=10
Then, move the 1 over so you get 3y=10-1 which makes 3y=9
Then, divide the 3 and you end up with y=3

To find x
plug y back into the ORIGINAL formula x=1+y OR 2y+x=10
assuming u used x=1+y you would get x=1+3
which gives you x=4

What is the area of this?

Vanyuwa [196]

$area = lw \\ area = (7.5)(6) \\ area = 45 {feet}^{2}$

$area = \frac{1}{2} bh \\ area = \frac{1}{2} (6)(4) \\ area = \frac{1}{2} (24) \\ area = 12 {feet}^{2}$

total area = 45 + 12

total area = 57 feet²

Describe one error that was made in the preparation of the

pashok25 [27]

Answer:

the axis labels are inconsistent with the graph title

Step-by-step explanation:

The independent variable is described as "% protein digested", and the dependent variable is described as "time." The graphed values suggest that these are reasonable descriptors for the data being plotted.

The title, however, says the data points are "percentage digestion per hour". This is in disagreement with the axis labels, and is inconsistent with the shape of the curve. (If the title is to be believed, the digestion rate is such that more than 100% of <whatever> has been digested after 10 hours.)

<em>Additional comment</em>

Another error is the vertical axis is graduated as though it were linear, but it is decidedly non-linear. Equivalent distances on the graph are shown for differences of 10%, 5%, 10% and 25%. That is the scale varies by a factor of 5 from one part of the graph to another.
