Answer:
Hello!
Step-by-step explanation:
The ordered pair answer is (1, 3) And I have attached a picture of the graph!
Answer:
D) x = -7.5
Step-by-step explanation:
x + 8 = 0.5
Subtract 8 from each side
x+8-8 = .5 -8
x = -7.5
Answer: (1, 3)
Explanation:
2x + 4x - 1 = 5
6x = 6
x = 1
y = 4(1) - 1
y = 4 - 1
y = 3
Answer:
Put it in between the 0 and -1. Put it on the last line closer to the -1 but not on the -1.
Step-by-step explanation:
This is because 3/4 in general is less than one.
Answer:
Fast car = 45.6
Slower car = 30.4
Step-by-step explanation:
Let the speed of the first car = x
Let the speed of the second car = y
Travelling towards each other.
x *1 + y*1 = 76 miles
x*5 - y*5 = 76 miles. This is kind of tricky. You have to understand that the first car that is 76 miles from the second car and makes up that 76 in 5 hours. The distance they both travel is subtracted out.
Divide by 5
x - y = 76/5
x - y = 15.2 The speeds differ by 15.2
x + y = 76
x - y = 15.2
2x = 91.2
x = 45.6
y = 76 - 45.6 = 30.4
When the two vehicles speeds are multiplied by 5, the difference is 76 km
