A. -5 < y < -3 is the correct answer.
Remark
This may be a little confusing, but because they are travelling in opposite directions, the distances add when you want to get how far apart they are.
d1 + d2 = 1541
Equation
Let the time this happens = t
d1 = 323*t
d2 = 347*t
323*t + 347*t = 1541 Combine like terms on the left.
670t = 1541 Divide by 670
t = 1541/670
t = 2.3 hours pass before the distance of 1541 miles are between the two planes. You might need the answer to be 2 hours 18 minutes.
Answer:
7
Step-by-step explanation:
Answer:
y = -x + 7
Step-by-step explanation:
The slope formula is as follows:
y = mx + b
So, in order to get x + y = 7 into slope intercept form we have to do the following things:
- Subtract x from both sides
If you do this step then your equation should look like this:
y = -x + 7

Compare each place value. It's kind of hard to explain without examples...
