Please tell me if these answers are correct:
1. Is ( 0, 3) a solution to the equation y = x + 3?
Yes
No
2. Is ( 1, -4) a solution to the equation y = -2x?
Yes
No
3. Look at the following points:
( 4, 0)
( 3, -1)
( 6, 3)
( 2, -4)
Which are solutions to y = x - 4
(2 correct answers)
A. ( 6, 3)
B. ( 4, 0)
C. ( 3, -1)
D. ( 2, -4)
4. Give an example of an open equation
5. How can you use an equation to make a prediction from a pattern?
6. Pizza costs $1.50 per slice. Use a table and an equation to represent the relationship between the number of slices of pizza bought and the total cost.
I think
1. Yes
2. No
3. ( 4, 0) and ( 3, -1)
4. Well, an algebraic open equation (also known as an open sentence) is a mathematical equation that is neither true nor false. so an example of an open equation could be x + 3 = 7 or 2x = 12
6. y=1.50x; y=total number of slices x= the amount of slices 1.50=the cost of one slice
correct on 1,2,3,4,
6. No.
totalcost=numberslices*1.50
5. the equation gives the relationship between one variable and another.
1.A
2.B
3.B,C
4.B
1.a
2.b
3.bc
4.b
@Jazzzmin is correct! & so is everyone else with the same answer!
The answers you provided are mostly correct. Here are the correct answers:
1. Is (0,3) a solution to the equation y = x + 3?
Correct answer: Yes
2. Is (1,-4) a solution to the equation y = -2x?
Correct answer: Yes
3. Which points are solutions to y = x - 4?
Correct answers: B. (4,0) and C. (3,-1)
4. Give an example of an open equation.
Correct answer: An open equation would be something like x + 3 = 7, where x is a variable and the equation is not making a definitive statement.
5. How can you use an equation to make a prediction from a pattern?
Answer: You can use an equation to find the relationship between the variables in a pattern. Once you find the equation that fits the pattern, you can use it to predict values for other inputs in the pattern.
6. Pizza costs $1.50 per slice. Use a table and an equation to represent the relationship between the number of slices of pizza bought and the total cost.
Answer: You can create a table with the number of slices (x) and the total cost (y) and use an equation to represent the relationship. The correct equation would be y = 1.50x, where y is the total cost and x is the number of slices.
