Answer:
its b because the answer for y needs to change in order for the x column to be true
Answer:
A
Step-by-step explanation:
To evaluate f(2), substitute x = 2 into f(x), that is
f(2) = 2(2)² - 5(2) = 2(4) - 10 = 8 - 10 = - 2 → A
When it comes to hundreds and thousands and even millions, you can tell how much bigger something is by how many more zeros are at the end. Each new zero added, is another rank up. The system goes:
1=10x bigger
2=100x bigger
3=1000x bigger
4=10000x bigger
5=100000 bigger
so on and so forth. There are 2 zeros in 700, and only 1 zero in 70, the difference in zeros is 1, so you can refer to the chart and conclude that 700 is 10 times bigger than 70. You could also divide 700 by 70 to get 10. This is more accurate, but the chart is simpler.
Answer:
y=1/5x+7
Step-by-step explanation:
just checked it on paper
If two lines are perpendicular, then the product of their slopes is -1:
From the problem, we identify:
Then, using the equation (1), we calculate the slope of the green line:
