The expression is 5x - 2y
Use PEMDAS and work out the rest
x = 3 and y = 4
5 x = 5 x 3 = 15
2 y = 2 x 4 = 8
15( x ) - 8 (y) = 7
The answer is 7
Hope This Helps You!
Good Luck Studying :)
Answer:
2
Step-by-step explanation:
The average rate of change from x=1 to x=2 is the same as finding the slope of a line at x=1 and x=2.
So we are going to need to corresponding y coordinates.
What y corresponds to x=1? y=3
What y corresponds to x=2? y=5
So we have the ordered pairs (1,3) and (2,5).
Line the points up vertically and subtract vertically then put 2nd difference over 1st difference.
(2 , 5)
-(1 , 3)
-----------
1 2
The average rate of change is 2/1 or just 2.
Now since we were asked to find the average rate of change given the function was a line, it really didn't matter what two points you used on that line.

The best graph that fit the given description is option A
Answer:
area of shaded region: 21.07 ft²
<u>Given for semi circle:</u>
- radius of semi-circle: 7 ft
<u>Given for rectangle:</u>
<u>Find area of rectangle:</u>
Length * Width
14 * 7
98 ft²
<u>Find the area of semi circle:</u>
1/2 * π * r²
1/2 * 3.14 * (7)²
76.93 ft²
<u>Area of shaded region:</u>
area of rectangle - area of semi-circle
98 ft² - 76.93 ft²
21.07 ft²
Answer:
0.028 Gallons/mile
Step-by-step explanation:
1 Gallon = 3.78541 Litres
1 Mile = 1.60934 Km
Total Fuel Expenditure (Dec 2019) = PKR 7,000
Fuel cost / Litre = 114Litre/Km
Total Fuel consumption = (7000/114)
= 61.40 Litres or 16.22 Gallons
Total Distance Travelled in Dec 2019 = 921 Km or 572.28 miles
Fuel Economy = 16.22/572.28
= 0.028 Gallons/mile
One time tank fill up cost = PKR 1,500
