Algebra 1 final semester 1

A child jumps straight in the air on a trampoline, y=-4t²+20t. How many seconds was the child in the air?

• 26sec
• 15sec
• 5sec
• 7sec

Simplify the expression, 8+√32 divided by 2.

• 4+2√2
• 8+2√4
• 5+2√4
• 2+2√3

To solve this equation, I first could

5x + 1 = -7x - 4

• add 5x to both sides

• add 7x to both sides

• add 1 to both sides

• subtract 4 from both sides

4x means 4 ___________ x

• plus

• minus

• times

• divided by

5x + 3 = 8x

• True

• False

What is the slope of this line:
2x - 3y = 21

• ⅔
• - 3/2
• - 3
• -7

complete the proportion:

• 130
• 47
• 180
• -12

Which coordinate is a solution to the inequality:

• (-2, -1)
• ( 3, 3)
• (4, 2)
• There is no solution

What is the equation of this inequality:

• y < -x + 2
• y < x - 2
• y > x + 2
• y ≤ 2x -2

Solve for x:
4x - 17 = 3x

• x = 17
• x = -17/7
• x = - 7
• No Solution
