Step-by-step explanation:
Jake, Becky, and Max are meeting at Charley's Pizza for dinner and then plan to go to a movie. When they arrive at the pizza place, each one of them has a different coupon. They decide to use the coupon that will give them the best deal. Jake's coupon is $19.99 for a pizza and pasta meal deal; Becky's coupon is for two large one-topping pizzas--each at of the menu price; and Max's coupon is for three medium one-topping pizzas -- each at off the menu price. According to the menu, a medium one-topping pizza is $8.99, and a large one-topping pizza is $14.89. They also spend $1.25 each for sodas and $5.00 on the tip. At the movie theater, Max has a coupon that's good for off a third movie ticket when you purchase two other movie tickets at the regular price. The regular price of each movie ticket is $9.80.
Although Jake, Becky, and Max plan to split the cost of the pizza and movie, they decide that with the coupons, it's just easier if one of them pays at each place. So, the friends agree that Jake will pay for the pizza and Becky will pay for the movies. At the end of the night, they'll figure out how much Max owes both Jake and Becky.
If Jake gives the server $30 at the pizza place, he should receive back ______
$1.50 in change (after leaving the tip).
A: More than
B: less than
C: Exactly

Which expression is equivalent to negative one half open parentheses three minus two fifths close parentheses?
negative three halves minus one fifth
negative three halves plus one fifth
negative three and one half minus one fifth
negative three and one half plus one fifth
The correct option will be B that is "Negative three halves plus one fifth" as the expression is -1/2(3-2/5) as defined "negative one half open parentheses three minus two fifths close parentheses".
What is expression?A finite combination of symbols that are well-formed in accordance with context-dependent rules is referred to as an expression or mathematical expression. No, a mathematical expression cannot be solved because it lacks the "equal to" sign $(=)$, but it can be simplified. Mathematical expressions consist of at least two numbers or variables, at least one math operation, and a sentence. It's possible to multiply, divide, add, or subtract with this mathematical operation. A number, a variable, or a combination of numbers, variables, and operation symbols make up an expression. Two expressions joined by an equal sign form an equation. For instance: 8 plus 3 is the sum. The result of adding 8 and 3 is 11. written as 8 + 3.
Here,
-1/2(3-2/5)=negative three halves plus one fifth
As the expression is -1/2(3-2/5) as defined by "negative one half open parentheses three minus two fifths close parentheses," option B, which is "Negative three halves plus one fifth," will be the correct answer.

Answer:
1. m = 3x
2. Possibly doesn't have a constant rate of change, because if you were to multiply 4.9 to the other coordinates/points/x values provided, you would not get the correct value for y, this means that the rate of change is not constant. Not only that but if you are to find a value that can multiply and add up to each, it would not go with the first coordinate.
3. The constant rate of change is found to be: m = 0.375
Step-by-step explanation:
In the question, it is asking for the constant rate of change.
This can be found determined by the graphs:
x | y
5 | 15
8 | 24
12 | 36
24 | 72
From what is shown, on x's side, we can see that:
5 · 3 = 15
8 · 3 = 24
12 · 3 = 36
24 · 3 = 72
This means that the constant for the first graph is m = 3x.
x | y
2 | [tex]\frac{3}{4}[/tex]
4 | [tex]1\frac{1}{2}[/tex]
6 | [tex]2\frac{1}{4}[/tex]
8 | 3
If you change the fractions into decimals:
[tex]\frac{3}{4}[/tex] = 0.75
[tex]1\frac{1}{2}[/tex] = 1.5
[tex]2\frac{1}{4}[/tex] = 2.25
= 3.00
(The change is + 0.75)
0.75 + 0.75 = 1.5
1.5 + 0.75 = 2.25
2.25 + 0.75 = 3.00
(But what about multiplying it?)
It is found that 0.75 DOES NOT work with muliplying, BUT we can find the rate of change if we divide 0.75 by 2
[tex]\frac{0.75}{2}[/tex] = 0.375
This would be your rate of change!
