Answer:
graphs left to right have a=1, a=0.25, a=-1
Step-by-step explanation:
A negative value of 'a' makes the parabola open downward, so the rightmost graph goes with a=-1.
A value of 'a' less than 1 flattens the graph, so the middle graph goes with a=0.25.
A value of 1 gives a standard open-upward parabola, corresponding to the leftmost graph.
Answer:
C
Step-by-step explanation:
So the system is:
5x+13y=232
12x+7y=218
------------------
Let's look at the options to see which will work:
A) Multiply first equation by -13: -65x-169y=-3016
& second equation by 7 : 84x+49y=1526
There are no opposites in the either one of the variable columns so not this option.
B) Multiply first equation by 7: 35x+91y=1624
& second equation by 13 : 156x+91y=2834
There are no opposites in the either one of the variable columns so this is not option unless we were asked to subtract the equations.
C) Multiply first equation by -12: -60x-156y=-2784
& second equation by 5 : 60x+35y=1090
There is a column that contains opposites here so when you add the equations the x-variable will get eliminated.
Hundredths are the second number after the decimal, which is the 7. The number, 5.476, rounded is 5.48. You round numbers by looking at the number after what place you want to round by. For example, if I had 5.28 and wanted to round it to the nearest tenths, I would look at the number after 2, which is 8. If the number is 5 or higher and one to the place you need to the round. If it’s 4 or lower, just take away the numbers after the place you need to round, so it would be 5.3. However, if it was 5.23 and I wanted to round it to the tenths, I would just take away the three, making it 5.2
