Reduced by half = 200cm/50 seconds.
20000/50 = 400.
200 x 400 = 80,000cm
Answer: both our A
Step-by-step explanation:
Coordinate form is (x,y) using the variables respectively.
2x+2y=-2
-2y
2x= -2-2y
/2
x=-1-y
9x-6y=36
9 (-1-y)-6y=36
-9-9y-6y=36
+9.
-9y-6y=45
-15y=45
/-15
y=-3
x=-1-y
x=-1- (-3)
x=2
answer: (2,-3)
Answer:
C. $16.00
Step-by-step explanation:
First, let's find how much they profit from one loaf
The profit is the difference between how much they sell it for and what they buy it for.
So, we can subtract what they buy the bread for from how much the sell it for
selling price-buying price
2.40-0.80=1.6
So, they profit $1.60 per loaf
To find how much they profit for 10 loaves, multiply their profit from one loaf by 10
profit*10
1.60*10=16
The profit for 10 loaves is $16, or choice C
Step-by-step explanation:
Given the table:
Month f(x) = Number of imports g(x) = Number of exports
January (1) 3 1
February (2) 4 3
March (3) 5 5
April (4) 6 7
From the table, it is clear that:
Number of imports = number of month + 2
so

also
Number of exports = 2(number of month) + 1
so

Therefore, number of imports equals the number of month plus one. i.e.
, which is a linear function.
If we compare it with slope-intercept form of the line

Then,
slope = m = 1
y-intercept = 2
Also number of exports equals is also a linear function.
i.e. 
Here,
slope = m = 2
y-intercept = -1
