10 the answer is c. i don’t know if that’s correct
Odd degree and negative leading coefient
means it goes from the top left to bottom right
goes infinitely down
as x aproaches infinity, y approaches neagtive infinity
<span>pennies = 0.01 $
nickels = 0.05 $
dimes = 0.1 $
quarters = 0.25 $
We must write the system of equations that best suits this problem and solve it:
Let:
x = pennies
y = nickels
z = dimes
w = quarters
Writing the equations
0.01x + 0.05y + 0.1z + 0.25w = 3.71
I have twice as many dimes as nickels
z = 2y
two more nickels than quarters
y = w + 2
three fewer pennies than three times the number of nickels
x = 3y-3.
Solving the system of equations:
x = 21
y = 8
z = 16
w = 6
answer
He has
21 pennies
8 nickels
16 dimes
6 quarters

Answer:
b = c - 3/4y
Step-by-step explanation:
move 3/4y to the other side with c:
c - 3/4y = b
b = c - 3/4y
To get the y coordinate that goes with the x-coordinate of 50, substitute 50 into the equation for x:
y = 3(50)-4
Now, solve for y by multiplying 3 times 50 and then subtracting 4:
y = 150 - 4
y = 146
So, now you know the y coordinate is 146 when the x coordinate is 50.
Hope that helps!
