(2(3x4))+(2(4x8))+(2(3x8)) = 24+64+48 = 136
Answer: C
The consumption rate of the car from previous part was 55 mpg (miles per gallon).We convert this to kilometers per liter.
1km = 06214 miles
1 gallon = 3.788 liters
hence, 55 mpg will be;
55× 1/0.6214×1/3.788 = 23.4 km / L
Thus, its mileage will be 23.4 km/L
For a distance of 1800 km the car will use; 1800/23.4 = 76.923 L
but, we know that the car gas tank holds 45 L
Hence, for a distance of 1800 km the car will use 76.923/ 45= 1.7094 tanks
That will be 1.7 tanks ( two significant figures)
28 x 12 = 336
336 - 16 = 320
320 divided by 4 = 80
80

Just plug the corresponding x value on the left of a,b,c, and d into the equation. If you don't understand the equation, it is asking you to multiply x by 3 and then subtract 2.
These are the answers:
-11, -5, 1, 4.
Good luck!

Answer:
y = -1/2x+7
Step-by-step explanation:
First find the slope using the slope formula
m = ( y2-y1)/(x2-x1)
= (3-5)/( 8-4)
= -2/4
= -1/2
The slope intercept form is
y = mx+b where m is the slope and b is the y intercept
y = -1/2x+b
Substitute a point into the equation
3 = -1/2(8) +b
3 = -4+b
Add 4 to each side
3+4 = -4+b+4
7 = b
y = -1/2x+7
