Answer:
2
Step-by-step explanation:
Take 1/2 of 1 and square it and add to both sides
1/2 squared=1/4, add to both sides
x^2+x+1/4=19/4+1/4
factor perfect square
(x+1/2)^2=20/4
(x+1/2)^2=5
square root both sides
x+1/2=+/-√5
minus 1/2 both sides
x=-1/2+/-√5
x=-1/2+√5 or
x=-1/2-√5
B is answer
Area of parallelogram = bh
To solve for the height you'll have to divide the area by the base length.
Hope this helps :)
Hi sorry for the late response, I know the assignment was due at 5pm today but anyway here is the answer.
System:
<em>d= 5(0.75-t)</em>
<em>d= 20t</em>
<em>20t = 3.75 -5t</em>
Define Variables:
<em>d = how far Carol Skied</em>
<em>t = time it took Carol to go up/down</em>
Solve:
20t = 3.75 -5t
20t + 5t = 3.75 -5t + 5t
25t = 3.75
25t/25 = 3.75/25
t = 0.15
<u><em>Now we plug in the time into the Distances:</em></u>
20t = 3.75 - 5t
20(0.15) = 3.75 - 5(0.15)
3 = 3.75 - 0.75
3 = 3
Solution as Sentence:
<u><em>Carol Skied 3 miles</em></u>
<u><em /></u>
Answer:
Step-by-step explanation:
The point slope form is expressed as
y - y1 = m(x - x1)
Where
m represents slope
Slope, m =change in value of y on the vertical axis / change in value of x on the horizontal axis
change in the value of y = y2 - y1
Change in value of x = x2 -x1
y2 = final value of y
y 1 = initial value of y
x2 = final value of x
x1 = initial value of x
The given points are (2,6) and (-1,3)
y2 = 3
y1 = 6
x2 = - 1
x1 = 2
Slope,m = (3 - 6)/(- 1 - 2) = - 3/- 3 = 1
To determine the equation, we would substitute x1 = 2, y1 = 6 and m= 1 into the point slope form equation. It becomes
y - 6 = x - 2
