Answer:
y=x-4
Step-by-step explanation:
Standard form is y=mx+b
the coordinates (0, -4) tell you that the y intercept is at -4 which means b will be -4. To find slope you have to find the change in y over the change is x. 1--4=5 and 5-0=5. 5/5 is 1 so the slope, or m, is 1. x stays the same since it's the variable. it'll become y=1x-4 and since you don't have to place a coordinate of one in front of a variable, you can just write it as y=x-4
Here, you are looking at two numbers, x and y, such that
, or, if you say that x is the larger of the two, simply
. You are looking to minimize the value for
. The smallest possible numbers are
. You might initially be tempted to think that you should choose an infinitely negative number and a number 18 more than it; however, the product of two negative numbers is positive, so this would become an infinitely large number. Then, it might be tempting to say 18 and 0, because their product, after all, is zero. But it is possible to get a negative product with a positive and a negative number. The least product is when
, and this will apply for any difference you choose, not just 18.
In sum, it's 9 and –9.
1.5+(-8.3)
=1.5-8.3
-6.8
The answer is -6.8
Answer:
10
Step-by-step explanation:
half of 10 is 5
Answer:
The Falcones have to travel at 25 m/h to make the trip in 2 hours.
Step-by-step explanation:
In order to find the answer you have to use the formula to calculate speed:
speed=distance/time
distance=50 miles. The stament indicates that the distance between Syracuse and Buffalo is 1 inch and that the map has a scale of inch = 50 miles.
time=2 hours
Now, you can replace the values on the formula:
speed=50 miles/2 hours
speed=25 m/h
According to this, the answer is that the Falcones have to travel at 25 m/h to make the trip in 2 hours.
