<h2>10 + 5x ≤ -15</h2>
Step-by-step explanation:
<u>sentence</u> <u>—————————-——————></u> <u>math expression</u>
Ten increased by —————————————> 10 +
the product of a number ‘x’ and 5 —————> 5x
less than -15 —————————-——————> ...... ≤ -15
<em>Conclusion</em>:
10 + 5x ≤ -15
Step-by-step explanation:
1.(4,9) & (1,6)
m=y²-y¹/x²-x¹
m=6-9/1-4
m=-3/-3
m= 1
2.(5,3) & (5,-9)
m=y²-y¹/x²-x¹
m=(-9)-3/5-5
m=-12/0
3.(2,1) & (8,9)
m=y²-y¹/x²-x¹
m=9-1/8-2
m=8/6
m= 4/3
4.(14,-8) & (7,-6)
m=y²-y¹/x²-x¹
m=(-6)-(-8)/7-14
m=2/-7
m= -2/7
5.(4,-3) & (8,-3)
m=y²-y¹/x²-x¹
m=(-3)-(-3)/8-4
m=0/4
m=0
6.(-11,1) & (-2,6)
m=y²-y¹/x²-x¹
m=6-1/(-2)-(-11)
m=5/9
117 miles in 2.25 hours
Divide both numbers by 2.25
52 miles per hour
To solve this problem first subtract the 4 from 120.
120 - 4 = 3y + 4(-4) =
116 = 3y.
Then divide both sides by three.
116 / 3 = 3y / 3 =
38.6666666667 = y
y = <span>38.6666666667.</span>
To double check the answer , 38.6666666667 x 3 + 4 = 120.
