To solve this, plug in your given x value (9 minutes) in for x in your formula, so w(x)=60(9)=540 words as your answer.
Answer:
c
Step-by-step explanation:
have a good day :D
to find the slope you take two points and add the y values and divide it by the x values
so you take the points (0,-2) and (3,2)
the y values are -2and2
2+2=4
the x values are 0 and 3
0+3=0
4/3=4/3 so that table does represent an equation with a slope of 4/3
sorry if this doesnt make sense its hard to explain virtually

Answer:
Step-by-step explanation:
We have been given that Juan cuts a piece of rope that is 16 meter long into 2 equal pieces. We are asked to find the length of each shorter piece of rope.
To find length of each shorter piece of rope, we will divide total length of rope by 2 because Juan cuts the rope into two equal pieces.
Therefore, the length of each shorter piece of rope would be 8 inches.
The function is:
f ( x ) = x² - x - 72
This is a quatdratic function. So we can find the zeroes of the function with the formula:
x 1/2 = ( - b +/- √(b² - 4 ac) ) / ( 2a )
And we have: a = 1, b = - 1 and c = - 72
x 1/2 = ( 1 +/- √((-1)² - 4 · 1· ( - 72 )) ) / 2
x 1/2 = ( 1 +/- √( 1 + 288 ) ) / 2
x 1/2 = ( 1 +/- √289 ) / 2
x 1/2 = ( 1 +/- 17 ) / 2
x 1 = ( 1 - 17 ) 2 = - 16 / 2 = - 8
x 2 = ( 1 + 17 ) / 2 = 18 / 2 = 9
Answer: The zeroes are - 8 and 9.
