Answer:
(x,y) = -1/2 , 3/2
Step-by-step explanation:
Let y = x +2 ----- (1)
y = -3x ------ (2)
Put equal both sides x +2 = -3x
x = -3x -2
x +3x = -2
4x = -2
x = -1/2 Put it in 2nd equation
Y = -3 (-1/2)
y = 3/2
so (x,y) = -1/2 , 3/2
Hope you got it.

Answer:
y=-1/2x+2
the y-intercept is at 2 and the slope is -1/2
meaning the y coordinates with move down 1 while the x coordinates will move 2 in a positive (right) direction
Answer:
2,000(1.04)t
Step-by-step explanation:
To determine this answer, you would use the formula initial value (1 + interest) times the number of years. This would equal 2,000(1.04)t.
<u>Answer:</u>
The element is Chromium.
<u>Explanation:</u>
The atom has 24 protons and 12 neutrons.
We know that Cr has 24 number of protons, to the Chemical is Cr (Chromium)
Again, we know that the atomic number is the number of protons and the atomic mass is the sum of proton and neutron.
So, the atomic number is 24 and the atomic mass is (24+12)= 36
Therefore, the symbol is 
Answer:
300 people rejected part A and part B.
Step-by-step explanation:
First let's review the information given by the statement of the exercise.
1000 people surveyed.
600 reject part A, 500 part B and 200 reject no one. Therefore, of those 1000, 800 reject a party, either A or B, since 1000 respondents - 200 who do not reject = 800 who reject.
Among the respondents there are a total of 600 + 500 rejections, that is to say 1100 rejections in total.
But we know that there are only 800 respondents left, therefore the people who rejected two, is the difference between total rejections and the remaining respondents. that is to say:
1100 - 800 = 300, which means that 300 people rejected part A and part B.
