Answer:
-3x+4
Step-by-step explanation:
flipping over the x-axis turns the 3 to a negative and shifting up 4 units is simple, it's just adding a +4. Hope this helped!!
Answer:
The probability of rolling an even number would be or 50%.
Step-by-step explanation:
A standard number cube has 6 sides that features numbers 1 to 6 on each side. Since there are three even numbers (2, 4, 6) total on the sides of the number cube, that means the theoretical probability of rolling an even number would be , which simplifies to or 50%.
Answer:
12 nickels and 9 dimes
Step-by-step explanation:
1/ We have: n + d = 21 <=> d = 21 - n or opposite (n = 21 - d)
2/ We have: 0.05n + 0.10d = 1.50 and then we will put 1/ into 2/
=> 0.05n + 0.10(21 - n) = 1.50
=> 0.05n + 2.1 - 0.1n = 1.5
=> -0.05n = -0.6
=> n = 12
Nevertheless, d = 21 - n = 21 - 12 = 9
The equation of the value of the car over a year is 2357.14x + y = 33,000. Then the value of the car 4 years after it was purchased is $23571.43.
<h3>What is the linear system?</h3>
A Linear system is a system in which the degree of the variable in the equation is one. It may contain one, two, or more than two variables.
A new car is purchased for $33,000 and overtime its value depreciates by one half every 7 years.
Then the value of the car is given by the linear equation. Then the line is passing through (0, $33,000) and (7, $16,500). Then we have
Let y be the value of the car and x be the number of years. Then we have
Then the value of the car 4 years after it was purchased, to the nearest hundred dollars will be

So, after the nail set is bought, she will have 80-16 left, that is 64. If each pair of earrings costs 8 dollars, then she can buy 64/8 =8: She can buy 8 pairs of earrings.
I don't see how you can make an "inequality" with this.
If the question is interpreted that she doesn't spend all her money, then we could say, if we must that if y=number of earrings she can buy then
y≤8
