Answer:
Step-by-step explanation:
y = -x - 9
y = 2x + 3
Find point of intersection
2x + 3 = -x - 9
x = -4
Intersection: (-4,-5)
Answer:
86 yd
Step-by-step explanation:
the area of the shaded region is 2924 yd²
let b the doted side next y :
the area of the total triangle is :
A = (y+b)*68/2 = 2924+ b*68/2
- = + 2924
- = 2924
- 68*y/2 = 2924
- 68y = 2*2924
- y= (2*2924)/68
- y= 86 yd
Review your notes before tests. If they ask to only do odds in your homework, then do evens as well when you have the time. There’s always more you can study
Answer:
<em>45 minutes </em>
Step-by-step explanation:
We want to know how long it takes to an airplane to fly a distance of 375 miles, if the speed of the airplane is 500 miles per hour.
For this, we should divide the distance/speed to get the time that the plane needs.
T = 375mi/(500mi/h) = 0.75 hours
The plane needs 0.75 hours or 0.75*60 = 45 minutes to fly that distance.
