The slope is -5.
The point is (-3, 4)
The formula for point slope form is
y-y1=m(x-x1) where y1 and x1 are the coordiantes of the point and m is the slope.
This shows that the y coordinate is positive and the x coordinate is negative.
May seem counterintuitive. So just flip signs that you see in formula to make the actual point if you are confused.
Answer:
30
Step-by-step explanation:
25 times 1.2= 30
half of 43.6 is 21.8
9.6+12.2=21.8
9.6 length
12.2 width
9.6*12.2=117.12
so the area would be 117.12
Answer:
The answer to your question is car 1 = 30 gal and car 1 = 20 gal
Step-by-step explanation:
car 1 = a
car 2 = b
Efficiency of car 1 = 35 mi/gal
Efficiency for car 2 = 20 mi/gal
Total distance = 1450
Total gas consumption = 50 gal
Equations
35a + 20b = 1450 ------- (I)
a + b = 50 ------- (II)
Solve by elimination
Multiply equation II by -35
35a + 20b = 1450
-35a - 35b = -1750
Simplify
0 - 15b = -300
Solve for b
b = -300/-15
Result
b = 20
Substitute b in equation II to find a
a + 20 = 50
Solve for a
a = 50 -20
Result
a = 30
