First distribute the negative
(-x+2)(x-7)
Next multiply -x by x
Then multiply 2 by x
Then multiply -x by -7
Then multiply 2 by -7
-x^2+2x+7x-14
-x^2+9x-14 is your answer
Answer:
x = 5.57
Step-by-step explanation:
c² = a² + b² − 2ab cos C
x² = 10² + 6² − 2(10)(6) cos 29°
x = 5.57
Your answer and steps are correct.

Determine the difference in the highest speed and the average speed
<em>Hence, the highest speed is 283.2 miles/hour faster than the average speed</em>
Answer:
slope is undefined
Step-by-step explanation:
Calculate the slope m using the slope formula
m = (y₂ - y₁ ) / (x₂ - x₁ )
with (x₁, y₁ ) = (9, 2) and (x₂, y₂ ) = (9, - 5)
m = =
Since division by zero is undefined then the slope is undefined.
This indicates that the line is vertical.
-16 = 8x/5......8x/5 is the same as 8/5(x)
-16 = (8/5)x...divide both sides by 8/5
-16 / (8/5) = x
-16 * 5/8 = x
-80/8 = x
-10 = x <===
