6z+7
Step-by-step explanation:
Answer:
14
Step-by-step explanation:
It says 'Evaluate (y - 9) + (3 + x), when y = 15 and x = 5'.
So we'd put 15 in y's place. It'll look like this (15 - 9).
Then we'd put 5 in x's place. It'll look like this (3 + 5).
You subtract (15 - 9) which equals 6. And you'd add (3 +5) which equals 8. You add 6 + 8 together since those are your answer for the parentheses. Your final should be 14. Hopefully this helped!
Answer:
y = -2x + 5
Step-by-step explanation:
Find b using the m and (3, -1) given by plugging them into y = mx + b
-1 = -2(3) + b
-1 = -6 + b
5 = b
plub in m and b into y = mx + b
y = -2x + 5
They would be 76 miles apart.
Each boat is travelling for 2 hours. Therefore, we just need to multiply their speed by 2. This will give us the distance they traveled from the start.
2 x 17 = 34
2 x 21 = 42
34 + 42 = 76 miles apart
