Pythagorean Theorem: A^2 + B^2 = C^2
<span>We know A and C, let's find B by doing it backwards </span>
<span>C^2 - A^2 = B^2 </span>
<span>4^2 - 7 (square root of 7 squared is just 7) = B^2 </span>
<span>16 - 7 = B^2 </span>
<span>9 = B^2 </span>
I think the answer is 4x+7 for s
Only A is a function because it is the only one with just one input for every output. Function B has 4 in the x position twice.
2500/5=500 this is the unit rate
Answer:
60x + 15x = 210
