Answer:
y = ± sqrt(x+7)
Step-by-step explanation:
y = x^2 -7 solve for 'x' .... add 7 to both sides
y+7 = x^2 sqrt both sides
+- sqrt(y+7) = x switch 'x' and 'y'
y = +- sqrt(x+7)
Answer:
ok in this case will represent the height with a the bells with b and the hypotenuse with c so it will be c squared is equals to a squared plus b squared 12 squared + 5 squared is equals to c squared 12 square is 144 while 5 squared is 25 when added it is 169 so csquared is equals to 169 to get c we find √ 169 source is equals to 13
