Answer:
see below:
Step-by-step explanation:
2y–6=0
a. slope intercept form using y = mx + b
y = 6/2
y = 3
b. slope: use the slope intercept form: y = mx + b
slope = m = 0
c. y-intercept = (0,3)
I'll just clarify the choices you gave:
-<span>maximum amount of money you can charge on the credit card time before the credit card company starts charging late fees
</span>-l<span>east amount of money that must be paid at the end of a month
</span>-<span>period of time before the credit card company starts charging interest
If these are correct, then the answer is 'period of time before the credit card company starts charging interest'. </span>
Answer:
750 grams of 60% alloy
Step-by-step explanation:
Define x = amount of 60% alloy and y = amount of 20% alloy
Equating the amounts of gold:
0.6x+0.2y = 1000(0.5)
Since there must be 1000 grams total:
x+y = 1000
Writing the 2 resulting equations together:
0.6x + 0.2y = 500
x + y = 1000
Multiply the first equation by 5:
3x + y = 2500
x + y = 1000
Subtracting the 2nd equation from the 1st:
2x = 1500
x = 750
Answer: 750 grams of 60% alloy
The answers is A x=4.5y because for whatever y is you multiply it by 4.5 and it gives you your x. Trust me. They all match too; I checked.
That would be twenty-eight thousand, seven hundred and three.
Hope that helped :)
