Answer:
f(- 3) = - 5
Step-by-step explanation:
Given the point (- 3, - 5)
where x = - 3 is the input and y = - 5 is the output
The function can be represented by
y = f(x), that is
f(- 3) = - 5
It's a equilateral triangle with each side being equal to the radius.
So the area is
Answer:
x=9, y=10. (9, 10). The two numbers are 9 and 10.
Step-by-step explanation:
3x+5y=77
x+y=19
------------------
3x+5y=77
-3(x+y)=-3(19)
---------------------
3x+5y=77
-3x-3y=-57
-------------------
2y=20
y=20/2
y=10
x+10=19
x=19-10
x=9
Answer:
$8.5 per hour
Step-by-step explanation:
Number of overtime hours = 4 hours
Since overtime starts after 40 hours, then the number of hours worked = 40 + 4 = 44 hours
Total amount earned = $391
Let Hourly pay = x
Overtime pay = 1 1/2x = 3/2x
Therefore ;
40x + (4*3/2x) = 391
40x + 6x = 391
46x = 391
x = 391 / 46
x = 8.5
Hourly pay = $8.5 per hour
Answer:
14
Step-by-step explanation:
We can find the sum of these numbers by adding them together.
The cumulative rule of addition lets us add numbers together in any order we want.
So, for 2 + 3 + 4 + 5 …
2 + 3 = 5
So now we have 5 + 4 + 5
5 + 4 = 9
Now we have 9 + 5
And 9 + 5 = 14
So, your answer is 14
Hope this helps!
