Her average rate of the entire trip would be 2 hours since 12mph for 10 miles and 12 miles going 10mph would crossed each other out and have 10 miles go 10mph (1 hour) and 12 miles going 12mph(1 hour)
1+1=2
There was no temperature change. Simple, easy math.
The POPULATION increased by 22000
Answer:
y = -6/7x + 16
Step-by-step explanation:
Use the slope intercept equation, y = mx + b
Plug in the slope and given point, then solve for b:
y = mx + b
4 = -6/7(14) + b
4 = -12 + b
16 = b
Plug in the slope and b into the equation:
y = mx + b
y = -6/7x + 16
So, the equation is y = -6/7x + 16
Answer:
x - 3y + z
Step-by-step explanation:
Terms are just names for objects inside the equation -- anything that isn't an operation. A coefficient the is the number a given term (variable) is being mulitpled by. In this case, -3 for y, and 1 for. x. We can deduce from this the start of the expression (x has no coeff. bc of multiplicative identity)
x - 3y
We know we are missing one term, and we also know that the third term cannot be constant, so it must be another variable. In this case I have chosen Z, in theory it shouldn't really matter but z is the best variable name in this case.
