Answer:
(0,4)
(2,2)
Step-by-step explanation:
y=x^2-3x+4
x+y=4
the second one can be rewritten as y=4-x
so the system becomes
y=x^2-3x+4
y=4-x
therefore 4-x = x^2-3x+4
that is x^2-2x=0
we can write it as x(x-2)=0 a product is = 0 when one of its factors = 0
so the solutions for x are: x=0 and x-2= 0 that means x=2
to get y you simply use 0 and 2 as value of x for any of the two equations
and you get y=4 and y=2 respectively
Ok so... what wait weres the pic??

Choice A is false because they are rounding to the nearest tenth (one decimal place) and not nearest hundredth (two decimal places)
Choice B is false as well because 3.825 should round to 3.83. The 5 at the end tells you to round up.
Choice C is false too. The value 3.824 should round to 3.82. Not sure how they got 3.81, so it seems like a deliberate trick question or silly answer.
Choice D is true. The three decimal values are rounded properly to the correct number of decimal places.
Therefore choice D is the answer
For this case we have the following conversion:
1 pound = 16 ounces
Then we rewrite the sack weights:
14 pounds 9 ounces = 14 9/16
9 pounds 14 ounces = 9 14/16 = 9 7/8
Then, we subtract both values:
(14 9/16) - (9 7/8) = 4.6875 = 4 + 0.6875
Rewriting:
4 + 0.6875 = 4 + 6875/1000
4 + 1375/200 = 4 + 275/40
4 + 275/40 = 4 + 55/8
Answer:
the weight of the potatoes wendy use for the potato salad is:
4 + 55/8 pounds
