Answer:
Can you reformat?
So far, 0 is a solution to none of these.
Answer:
1. nope
2. not sure
3. nope
Step-by-step explanation:
1.
-3(y - 1) > 3
-3y + 3 > 3
-3y > 0
y > 0
0 is not a solution since 0 is not greater than 0
2.
I'm not sure what this question means, is there a [tex]\geq or \leq[/tex] between the 4 and the 0?
3.
y + 8 < 2y + 8
8 < 2y - y + 8
8 - 8 < y
0 < y
0 is not a solution because 0 is not greater than 0

Jeremiah dad Ordered five large pepperoni pizzas in each large cheese pizzas for the birthday party he spent a total of 144 on pizza if a pepperoni pizza cost 12 right and solve a linear equation to find the cost of a cheese pizza
This question is incomplete because part of the information is missing; here is the complete question:
Jeremiah's dad ordered 5 large pepperoni pizzas and 8 large cheese pizzas for the birthday party. He spent a total of $144 on pizza. If a pepperoni pizza costs $12, write and solve a linear equation to find the cost of a cheese pizza.
The answer to this question is $10.50
Explanation:
The first step to solve this problem is to write a linear equation. In this, the unknown should be represented by an x, and other variables should be included using correct mathematical symbols. Here is the process:
1. In an equation there is always an equality symbol = and mathematical expressions on both sides.
2. In this situation, the value after the = symbol should be 144 or the total spend on pizzas.
3. The values missing should be expressed as 5 (12) + 8x because there are 5 pepperoni pizzas and each of these costs $12; also, this should be added to the 8 cheese pizza and x represents the missing value (the price of a cheese pizza.)
4. Solve the equation
5 (12) + 8x = 144 -Simplify using multiplication
60 + 8x = 144 - Solve by moving the number to the right side and changing the symbol
8x = 144 - 60
8x = 84
x = 84 ÷ 8
x = 10.5
Q. If the vertex of a parabola is (3,5), what is the axis of symmetry?
answer choices
y=5
x=5
x=3
There is not enough information provided.
Answer:
x=5
Step-by-step explanation:
The axis of symmetry is x = 3 if the vertex of a parabola is (3,5) option (C) is correct.
What is a parabola?It is defined as the graph of a quadratic function that has something bowl-shaped.
We know the vertex form of the parabola is:
y = a(x - h)² + k
Given,
h = 3
k = 5
y = a(x - 3)² + 5
The axis of symmetry:
x - 3 =0
x = 3
Thus, the axis of symmetry is x = 3 if the vertex of a parabola is (3,5) option (C) is correct.

Which is the first error that Tomas made? Tomas substituted the 3 for x when he should have substituted 6 for x. Tomas added 6 to both sides of the equation instead of subtracting 6. Tomas should have written the equation as . Tomas substituted 3 for x when he should have substituted 3 for y.
Answer:
Tomas added 6 to both sides of the equation instead of subtracting 6Step-by-step explanation:
Find the complete question in the comment section.
Given the equation 2x+6y=12 to represent the total cost, where x represents the number of pounds of granola and y represents the number of pounds of walnuts.
If he buys 3pounds of granola, and he need to get amount of walnut, he should have substituted x = 3 into the expression to get y as shown:
[tex]2x+6y=12\\2(3)+6y=12\\6+6y = 12\\subtract\ 6 \ from \ both \ sides \\6+6y-6 = 12-6\\6y = 6\\y = \frac{6}{6}\\ y = 1[/tex]
Comparing the calculation with Tomas's, we can see that Tomas added 6 to both sides of the equation on line 3 instead of subtracting 6 from both sides of the equation. This was Tomas first error.
Answer:
Tomas added 6 to both sides of the equation instead of subtracting 6.

What is Venn diagram?
"A Venn diagram in mathematics is a diagram that uses overlapping circles or other shapes to represent the logical relationships between two or more sets of items. "
What is probability?"For any experiment, a probability denotes the possibility of outcome for any event."
The formula to calculate the probability of an event:For event A, the probability of event A is,
P(A) = number of favorable outcomes/ total umber of outcomes
What is conditional probability?"Conditional probability is the probability of an event occurring given that another event has already occurred."
The formula to calculate the conditional probability:P(A|B) = P(A∩B)÷P(B)
For given diagram:
Let A represents a set of students playing Basketball and B represents a set of students playing Soccer
So, A = {Fran, Ian, Juan, Ella}
⇒ n(A) = 4
B = {Mickey, Marcus, Ella}
⇒ n(B) = 3
(A ∩ B) = {Ella}
⇒ n(A ∩ B) = 1
sample space: S = {Fran, Ian, Juan, Ella, Mickey, Marcus, Mai, Karl, Jada, Gabby}
⇒ n(S) = 10
Now, we calculate probability of B and A∩B.
P(B) = n(B)/n(S)
⇒ P(B) = 3/10
Also, P(A∩B) = n(A∩B) / n(S)
⇒ P(A∩B) = 1/10
So, the required probability would be,
⇒ P(A|B) = P(A∩B) ÷ P(B)
⇒ P(A|B) = (1/10) ÷ (3/10)
⇒ P(A|B) = 1/3
Therefore, P(A|B) = 1/3

The square of 356 is 126,736 and the square of 357 is 127,449. What is 3582? Try to solve this problem without multiplying. Show your work.
Answer:
The problem to get 358² is solved by adding 357 twice and then add 1 to the value of 357²
Step-by-step explanation:
The given information are;
The square of 356 = 126,736
The square of 357 = 127,449
We note that 357² = (356 + 1)² = 356² + 2×356 + 1 = 126,763 + 712 + 1 = 127,449
We can write the above equation as follows;
357² = (356 + 1)² = 356² + 356 + 356 + 1 = 126,763 + 712 + 1 = 127,449
357² = 127,449
Similarly, we have;
358² = (357 + 1)² = 357² + 357 + 357 + 1 = 128,164
358² = 128,164
We can also look at the question as forming squares with tiles
To form the square tile with 358 units per side, we add an extra row and column of 357 tiles each. Completing the figure with an extra tile at the top right or left corner
Therefore, the area of the 358 unit per side square = The area of the 357 unit per side + 357 + 357 + 1 = 128,164

How much would it cost to make 25 shirts?
$ Answer
How much would students earn if they sold 25 shirts?
$ Answer
Will students make more money than they spent if they make and sell exactly 25 shirts?
Answer:
The answer is below
Step-by-step explanation:
The total cost for producing x number of shirts = 100 + 7x
The price of each shirt is $15, therefore:
Revenue = price per shirt × number of shirts = 15 × x = 15x
Revenue = 15x
The cost of making 25 shirts is given as:
Cost = 100 + 7x = 100 + 7(25) = $275
The money earned from producing 25 shirts is given as:
Revenue = 15x = 15(25) = $375
Since the revenue is greater than cost, the students would make more money than they spent if they make and sell exactly 25 shirts
