In order to assess which method of transportation is faster, we will look at the time they take, since the distance is the same for both. In order to compare the times, we must make the units that they are both measured in consistent. We must either convert 18.5 minutes into hour or 0.5 hour into minutes. We will go with the latter as it is easier:
0.5 hours = 0.5 hours x 60 minutes per hour = 30 minutes
Therefore, the public transport takes them to the mall faster, since it takes only 18.5 minutes, than cycling to the mall does, which takes 30 minutes.
Multiply the 1st row by 3
3x−12y=−3
3x+2y=39
Subtract the 2nd row from the 1st row.
−14y=−42
Solve for y (-14y=-42)
Divide both sides by −14.
Y= -42/-14
Two negatives make a positive.
Y=42/14
Simply 42/14 to 3
Y=3
Sub y=3 into both equations
3x-12x3=-3
X=11
Therefore,
X =11
Y=3
Answer:
it's false
the true is -1/2
Step-by-step explanation:
-5/2-2+4=-1/2
Answer: B
Step-by-step explanation:
The question asks for [n≥-5] to be true, which means any value that is greater or equal to -5 will be considered.
A. {-5, -5.5, -6}
-5 TRUE
-5.5 FALSE
-6 FALSE
B. {-5, -4.5, -3}
-5 TRUE
-4.5 TRUE
-3 TRUE
C. {-6, 0, 5}
-6 FALSE
0 TRUE
5 TRUE
D. {-6, -7, -8}
-6 FALSE
-7 FALSE
-8 FALSE
As shown above, we can clearly see that Set B is the set that makes the inequality true.
Answer: m = -5/8
Step-by-step explanation:
The general equation for slope is rise over run, also known as:
m=(y2-y1)/(x2-x1)
From the points (x, y), we can get all the variables we need.
(-1, -7) gives us x1 = -1 and y1 = -7
(-9, -2) gives us x2 = -9 and y2 = -2
If we plug all the values in, we get:
m = (-2 - (-7))/(-9 - (-1))
m = (-2 + 7)/(-9 + 1) the negatives cancel
m = (5)/(-8)
m = -5/8
