Slope = (y2-y1)/(x2-x1)
The points: (2,0) and (0,3)
(3-0)/(0-2) = 3/-2 = -3/2
The solution is -3/2
Answer:
A: 360
Step-by-step explanation:
Split the trapezoid into 2 shapes
Then find the area of the rectangle on the left:
18 × 15 = 270 square yards
Now for the triangle, first find the base by subtracting the 2 parallel lines:
25 - 15 = 10 yards
0.5(10 × 18) = 90 square yards
Add both areas to find total area:
270 + 90 = 360 square yards
All this can be seen in the figure below:
345 mi; if you travel 69 miles per hour, and drive 5 hours, you have to multiply 69 and 5 to find how far you travel in 5-- 69 times 5 is 345.
Answer:
The amount of the fee for the truck is $20 and cost per mile is $1.3.
Step-by-step explanation:
If they pay a fee x dollars for the truck and y dollars per mile they drive.
Carrie drives 150 miles and pays $215.
Her fee= $x for the truck + 150 X y =215
x+150y=215...(I)
Similarly, Dave drives 120 miles and pays $176
His fee =$x for the truck + 120 X y = 176
x+120y=176....(ii)
To determine the values of x and y, we solve Equations I and II simultaneously.
x+150y=215...(I)
x+120y=176....(ii)
Using elimination method (Subtracting equation II from I)
30y=39
y=1.3
Substitute y=1.3 into (I) to get x.
x+150y=215...(I)
x+(150X1.3)=215
x+195=215
x=215-195=20
Since x=20, y=1.3, The amount of the fee for the truck is $20 and cost per mile is $1.3.
