Answer:
A. (0,445)
D.(118,209)
E.(172,101)
Step-by-step explanation:
The equation that we have in this problem is:
where
d is the number of dimes
n is the number of nickels
$22.25 is the total amount of money collected by Diego in the jar.
In order to find which pairs of values can be solutions to the equation, we just need to substitute each pair (d,n) into the left term on the equation, and check if the result is 22.25. Let's do it:
A. (0,445)
--> YES
B. (0.50,435)
--> NO
C. (233,21)
--> NO
D.(118,209)
--> YES
E.(172,101)
--> YES
So the correct pairs are:
A. (0,445)
D.(118,209)
E.(172,101)
Answer:
the graph is 1/2, y intercept is -6, last one in -7
Step-by-step explanation:
The equation for profit is expected to be
daily profit = (profit on plate)*(number of plates) +(profit on cup)*(number of cups)
We are told that
profit on plate = k
profit on cup = k-1
Matching these to the expression above, we find
x = number of plates
y = number of cups
You are asked what y represents. It is
A. The number of cups sold in one day.
X^4+3x^3-2x^2-5x+8 can be one example
you put it over 1 and divide it by 10
