Answer:
17
Step-by-step explanation:
Let x be the number of books and y the number of CDs,
The prices of the products are multiplied with the quantity bought, therefore:
Multiplying the first equation by -5, then multiplying the two equations:
Answer:
-65
Step-by-step explanation:
h + 28 = -37
-28 -28
h = -65
Answer:
Step-by-step explanation:
Let the number of days be x because x is the independent variable
Any y is the number of calories consumed the dependent variable.
Now slope = y2 - y2/ x2 - x2
= 10600-4100/8-3
= 6500/5 = 1300
From our analysis we know it consumes 1300 per day so ideally on day 3 we expect him to consume 1300x3= 3900
But the given value is 4100
This means it's inherent energy is 4100-3900= 200
This is the y- intercept and it occurs when x= 0
from the above explanation we know that
C = 200. and it's the y- intercept.
Look at the general equation of a line
y = mx + C; when x= 0, y = C; note we define C as the value of y when x = 0
Step-by-step explanation:
Domain x belongs to [-4 , 0]
Range y belongs to [-4 , 4]
