Answer:
A
Step-by-step explanation:
To calculate the scale factor k, find the ratio of corresponding sides
= 
= 6
= 
= 6
Hence the scale factor k = 6 → A
Answer:
f(-4) = 5
Step-by-step explanation:
Explanation of
_
| 5, x < -3
f(x) | 2x² - 4, -3 ≤ x ≤ 4
| 1 - 6x , x > 4
_
When the x in f(x) is less than -3 than f(x) = 5
When the x in f(x) is greater than -3 but less than 4 then f(x) = 2x² - 4
When the x in f(x) is greater than 4 than f(x) = 1 - 6x
- - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - -
Now that we know this lets look back at the question.
We want to find f(-4).
Looking at the piece wise function we see that f(-4) follow x < -3 as "x" or -4 is less than -3. When x is less than -3, f(x) = 5, hence f(-4) = 5
Answer:
1.75
Step-by-step explanation:
7 divided by 4 where yo would get 1.75 and it is already rounded to the nearest hundreth ( im a 6th grader not positive if i got it right)
The answer is B:68
All you have to do is base times height and divide by 2
A=bh/2
A=17(8)/2
A=136/2
A= 68
2.8 is greater than 2.78 :)
If you look in the tens place and compare the two numbers, you will see that 8 is greater than 7. That’s how you know that 2.8 is greater than 2.78
