Answer:
-23
Step-by-step explanation:
-8+(-15) means that you are subtracting 15 from -8. So you end up with -8-15=-23.
Answer:
56
Step-by-step explanation:
40/10= 4 every hour
14x4=56
In order to answer this, you need to find the equation of the line. The equation of a line is y= mx + b; mx being the slope and b being the y- intercept. The y intercept is located at (0, 20).
To find the slope, take two points. Let's use (1,40) and (2,60).
Use the slope formula: (y1 - y2)/(x1 - x2)
(60-40)/(2-1)= 20/1= 20.
The slope is 20, the equation is: y = 20x + 20.
Now plug 10 into x:
y = 20(10) + 20
y = 220
Your answer is 220.
8 ones 4 tenths 7 hundredths and 8 thousandths
I would say y = sin(x + 2).
Why?
1. Is it the sine function for sure.
2. The function y = sinx is moved two places to the right as indicated by the +2.
3. The function y = sin(x + 2) crosses the point (2,0).
