You need to add the two quadratics together...
x^2+11x-6+6x^2-3x+9
7x^2+8x+3
Answer:
10 miles per hour
Step-by-step explanation:
speed= distance/time
30/3
=10
15. The answer that best fits the question would be the "First" option. the ( and ) are just things to say do the inner work first, then multiply.
16. The Third option is the answer that best fits the question. She is trying to find how many time she did something, so multiplication would be the answer.
Hope this helps!
The sum in sigma notation for the sequence will be as follows:
From
<span>5 + 10 + 15 + 20 + 25 + 30 + 35 + 40 + 45 + 50
first term=5
common difference=5
number of terms=10
n=nth term
thus the sum will be:
(i=2 to 10)</span>∑(5(n-1)+5)
Answer:
slope is undefined
ex. a straight vertical line like x = 2 would have an undefined slope
Step-by-step explanation:
formula is
y2-y1 / x2-x1
-13 + 9 / -5 + 5
-4 / 0
slope is undefined
straight vertical line like x = 2 would have an undefined slope
undefined slope is the slope of any vertical line that goes up or down. There is no horizontal movement and hence the denominator is zero while calculating the slope. Thus the slope of the line is undefined.
