Answer:
x=8
Step-by-step explanation:
Solve both formulas to y=mx+b (slope intercept formula) where m=slope and b=y-intercept
y=-3/1x+-7
x-2y=-14
-2y=-14-x
y=7+1/2x
Start with the b variable so for problem 1 put a dot on 0,-7 and for problem 2 put a dot on 0,7
Then from -7 for problem 1 depending on whether the slope is negative or positive go down 3 and over right 1 therefore another point for problem one is marked, at 1,-10; for problem 2 up 1 and to the right 2; 2,8
For problem one connect the dots of 0,-7 and 1,-10
For problem two connect the dots of 0,7 and 2,8
Answer: m=−y+3−x+2
x=2m+y−3m
Step-by-step explanation:
m(2−x)=3−y
Step 1: Factor out variable m.
m(−x+2)=−y+3
Step 2: Divide both sides by -x+2.
m(−x+2)−x+2=−y+3−x+2
m=−y+3−x+2
__________________________________________________
m(2−x)=3−y
Step 1: Add -2m to both sides.
−mx+2m+−2m=−y+3+−2m
−mx=−2m−y+3
Step 2: Divide both sides by -m.
−mx−m=−2m−y+3−m
x=2m+y−3m
Ava took 5 minutes out of 60 in an hour to do half a mile
5×2=10
60/10=6mph
Damon took 3 minutes out of 60
3×2=6
60/6= 10mph
Reina took 4 minutes out of 60
4×2=8
60/8= 7.5mph
Answer:
385.875 cm^3
Step-by-step explanation:
3.5/2 = 1.75
3.5^2 - 1.75^2 = 9.1875
3.5 * 9.1875/2 = 16.078
16.078 * 6 * 4 = 385.875
