Can someone me with these questions ?
1. which function pass through the points (1, 4), (2, 9), and (3, 16)?
y = (x + 1)2
y = (x + 3)2
y = 7x - 5
2. suppose that after swimming 1 lap in a pool, you can swim 10 laps in an hour. what is an equation that represents the total number of laps you have swam y in terms of the number of hours x?
y(x) = 10 + x
y(x) = 10(x + 1)
y(x) = 10x + 1
3. is the following an arithmetic sequence? if so, what is the common difference? {4, 2, 0, -2, -4, -6, …}
yes, d = -2
no
yes, d = 2
4. which function has the following graph?
y = -2x + 4 b. y = 2x + 4 c. y =12x + 4
5. what is the slope of the line containing (3, 5) and (2, 7)?
m = 2 b. m = -2 c. m = 125
6. the graph of a line passes through the point (-3, 2) and has a slope of 4. what is an equation of the line?
y = 4x - 10
y = 4x - 11
y = 4x+ 14
7. which line is parallel to y = 4x - 2?
y = -14x + 3
y = -4x + 5
y = 4x + 5
8. which system of equations has (2, 3) as a solution?
y = 2x - 1 b. y = 2x + 1 c. y = 4x - 5
y = x + 1 y = x - 1 y = 2x
