Answer:
x=-20
Step-by-step explanation:
x-3/4x=3/10x-1
20x-15x=6x+20
5x=6x+20
5x-6x=20
-x=20
x=-20
Answer:

Answer: 19nickels and 7dimes.
Ps i really don’t know where the 50.05 came from if it is suppose to be there then I really don’t know how to solve this.
Step-by-step explanation:
Ok so if you know that there are 19nickels, let n=number of nickels.
The number of total coins subtracted by number of nickels will give you number of dimes.
165-number of nickels=number of dimes
Value of dimes=10(number of dimes) or total value of dimes/individual value (10cent)
Then you can substitute total as $1.65 and get the value of nickels by multiplying by 5cent ( my teacher taught me using whole numbers to make it easier so I turned $1.65 to 165 cent). Since the value of the dimes is the value of nickels subtracted from the total, I can subtract 95 from 165 and divide the difference by 10, to get the number of dimes.
5(n)=5(19)=95
(165-95)/10=number of dimes
70/10=7dimes
You can check by multiplying 7x10 and 5x15 again and adding them together to see if they equal 165 cent.
Answer:
{y|y≥−2}
Step-by-step explanation:
The domain is {x|x∈R}
The range is {y|y≥−2}
Answer:
at 0 the amount is 5
1 is 7.5
2 is 10
3 is 12.5
the initial value is the y intercept when the value ox x=0
the initial value is 5
the rate of change is the total change of a function of the out put (y) divided by the change of the input (x)
f(x2)-f(x1)/x2-x1
10-7.5/2-1
2.5/1=2.5
or m=y2-y1/x2/x1=10-7.5/2-1=2.5
y=2.5x+5
