Answer:
A
Step-by-step explanation:
A quadratic graph is a graph that is y=mx^2+B. The x in the equation is to the power of 2 meaning it must go both way. (not the best explanation sorry)
Answer:
x = 13/8
y = -45/8
Step-by-step explanation:
9x + y = 9
3x + 3y = -12
Divide the second equation by 3
x+y = -4
Multiply this by -1
-x -y = 4
Add this to the first equation to eliminate y
9x + y = 9
-x -y = 4
-----------------
8x +0 = 13
Divide by 8
8x/8 = 13/8
x = 13/8
Now find y
x+y = -4
13/8 +y = -4
Subtract 13/8 from each side
13/8 -13/8 +y = -4-13/8
y = -32/8 - 13/8
y = -45/8
Answer:
B. NO
Step-by-step explanation:
Figure B can only be a scale copy of Figure A if the ratio of their corresponding side lengths are equal.
Let's find out:
9/3 = 3
7.3/2.2 ≈ 3.3
Thus:
9/3 ≠ 7.3/2.2
Since the ratio of their corresponding side lengths are not equal, therefore Figure B is not a scale copy of Figure A.
The answer is NO.
