Answer:

The friend caught the ball at 2 feet.

Step-by-step explanation:

1. False; the ball was not still in the air at 1 second the x-component of the vertex is 0.5.

2. False; the x-component of the vertex is 0.5

3. True; the ball was tossed at a height of 2 feet (when x=0, y=2), it is safe to assume the ball was caught at the same height.

4. False; when x = 0, y = 2.

Jill got an 85% on a math test if there were 40 questions in total,how many did she get wrong?
GrogVix [38]
You can solve this by setting up a proportion. You can put the number of items correct over the total number. and substitute the unknown number with x.

\frac{85}{100} = \frac{x}{40}   Cross-multiply
3400 = 100x   Divide both sides by 100
34 = x

40 - 34 = 6

So, Jill got 6 questions wrong.

What is the slope of the line?<br><br> 3(y-1)=2x+2
Aleks [24]

Answer: 2/3

Step-by-step explanation:

3(y-1) = 2x + 2

Expand: 3y - 3 = 2x +  2

Isolate the y by adding 3 to both sides: 3y = 2x +5

Isolate the y by dividing 3 from both sides: y = 2/3x +5/3

Remember, in y = mx + b, m = slope.

So, 2/3 is the slope.
