We use y=mx+c we know that c= 4 A’s this is the y intercept . Next we need to work out the gradient(m). For every two squares along we go three squares up. This means are gradient is 1.5. Finally we input are values into the equation y=1.5x+4
The distance traveled by the balloon in every minute makes an arithmetic sequence with a first term equal to 40 ft and common difference equal to 20. The nth term of an arithmetic sequence is calculated by,
an = a1 + (n - 1) x d
Substituting,
an = 40 + (15 - 1) x 20 = 320
Thus, the answer is letter B. 320 feet.
Answer:
x>-4
Step-by-step explanation:
-3x<12
x>-4
The answer is A, because 7.5 times 400 is 3000 so you need at least 400 boxes.
Hello,
So they don't intersect !!!!!!!!!!!!!!!!!!!!!!!
