Here is an inequality: −3x>18. 1. Which of the following describes the values for x that would make this inequality true. A. Any values greater than -6 A. Any values greater than -6 B. Any values less than -6 B. Any values less than -6 C. Any values greater than 21 C. Any values greater than 21 D. Any values less than 21 D. Any values less than 21 2. Explain how the solutions to the inequality −3x ≥18 different from the solutions to −3x > 18.
Answer: B because a negative x negative is a positive, making them all higher than 18. The first inequailty means it can be equal to 18 and the second means -3x has to be greater, ex 19 or above

Nancy has to find the reflection of a point across both the x- and the y-axes. Using what you've learned so far about reflections across the x-axis and reflections across the y-axis, can you come up with a rule for what happens to the signs when you reflect a point across both axes?
Answer:
Step-by-step explanation:
All she needs to know is that a reflection across the x-axis is when the x coordinate stays the same and the y-coordinates change.
Hope this helped.
Answer:
To find the reflection of a point across the x-axis and the y-axis, change the signs of both the x-coordinate and the y-coordinate.

Tom decides to pick up some pizzas and drinks for his family. He notices that the pizza costs the same as 7 drinks. The 2 pizzas and 8 drinks cost $33. What is the price of each item?
Answer:
Drinks = $1.5
Pizza = $10.50
Step-by-step explanation:
let d = drinks
p = pizza
p = 7d equation 1
2p + 8d = 33 equation 2
from equation 1, we know the price of one pizza, the price of two pizzas can be determined by multiplying by 2
2p = 7d x 2 = 14d eqn 3
Substitute for 2p in equation 2
14d + 8d = 33
22d = 33
Divide both sides of the equation by 22
d = $1.5
Substitute for d in equation 1
p = 1.5 x 7 = $10.5
A rental car agency charges $14 per day plus 12 cents per mile to rent a certain car. Another agency charges $19 per day plus 10 cents per mile to rent the same car. How many miles per day will have to be driven for the cost of a car from the first agency to equal the cost of a car from the second agency?

Answer:
One solution
Step-by-step explanation:
3-2x=5-x+3+4x
3-2x=3x+8 Combine like terms
3-8-2x+2x=3x+2x+8-8 Minus or add terms to get x on one side by itself
-5=5x Divide 5 to both sides to get x by itself
5 5
x=-1 The 5 is cancelled out on the side with the x and then divide it on the side with -5
Ty can jump rope at a rate of 6 jumps every 3 seconds. What is Ty's jump-roping rate in
jumos per minute? Explain your thinking.
Answer:
120 Jumps per Minute
Step-by-step explanation:
3 Seconds per jump
So we do 60 (seconds in a minute) / 3 (seconds)
We get 20, this is how many times we do the 6 jumps.
Then we simply do 6x20 to get 120 jumps per minute!

Answer:
102,9 cm^2
Step-by-step explanation:
First of all we can find the area of the two rectangles at the sides of the figure
A rectangle = length x width = 8 x 4 = 32 cm^2
the rectangles are two so:
32 x 2 = 64 cm^2
for the figure in the center we can proceed like this: we can initially assume that also it is a rectangle, so we have to find the length
length = 16-8 = 8 cm
A = 8^2 = 64 cm^2 (so we have discovered that is a square)
if we look we can see that there is also a semicircle that is not part of the figure. We have to find its area and subtract it to the area of the square
A semiciricle = (radius^2 π)/2
radius = 8/2 = 4 cm
A semicirlce = (4^2) π/2 = 25,13 cm^2
64 - 25,13 = 38,87 cm^2
At least we have to added up this value to the area of the two rectangles
total area = 38,87 + 64 = 102,87 = 102,9 cm^2

if the graph of f(x) = x is shifted up 9 units, what would be the equation of the new graph?
Answer:
x+9
Step-by-step explanation:
f(x) = x, going up 9
that is y=x, going up 9
if you wnat to go up, subtract 9 from y
y -9 = x
y=x+9
convert back to f(x)
f(x) = x+9
what is 4x – 97 + 12 – x = -80.5
Answer: x - 1.5
4x – 97 + 12 – x = -80.5
3 x - 85 = -80.5
3 x - 85 +85 = -80.5 + 85
3x = -80.5 + 85
3x = 4.5
x = 1.5
Step-by-step explanation: hope this helps
Answer:
x=1.5
Step-by-step explanation:
4x-97+12-x=-80.5
Combine like terms
-97+12=-85
4x-x=3x
now you have 3x-85=-80.5
add 85 to both sides and now you have
3x=4.5
Now divide 3 to both sides and you get x=1.5
one positive integer is 2 less than another. The product of the two integers is 24. what are the two integers?
If one is positive we can conclude that the other is also positive
Positive*positive=positive(24)
The product of the two numbers is 24
And the smaller number is less than the greater number by 2
Factors of 24=1*24,2*12,3*8,4*6.
The only pair with the diffrence of two is 4*6
Therefore the two integers are 4 and 6
Can someone help on really stuck
a number is two more than another number in number form?
From the information in the word problem we are able to set up the following inequality:
3y + 2 - y = 12 | where x is the larger number of two numbers in a set (x, y)
We know this because the problem states that [x = 3y + 2] or 3 times the smaller number plus two.
We also know that x - y = 12.
So, we substitute x in [x - y = 12] with 3y + 2 that we found out above, and we get the following:
3y + 2 - y = 12
Now, we solve the inequality
3y + 2 - y = 12
-> subtract 2 from both sides :: 3y - y = 10
-> subtract y from 3y :: 2y = 10
-> divide both sides by 2 :: y = 5
So now we have y, the smaller number, which is equal to 5. Next, to find x we simply plug y=5 back in to either the value of x, [3y + 2], or the inequality of x - y = 12. I will show both:
x - y = 12
-> substitute y for 5 :: x - 5 = 12
-> add 5 to both sides :: x = 17
OR
3y + 2 = x
-> substitute y with 5 :: 3(5) + 2 = x
-> multiply 3, 5 :: 15 + 2 = x
-> add 15, 2 :: 17 = x
So there you have it:
x = 17 , y = 5
You can go back and use these values to check your answer and make sure they work with the word problem.
Remember to look for the setup to an inequality in the word problem. Anything that says BLANK times this number, or 4 less than that number, is trying to set you up with an inequality problem.
