use a ti 84 or something
y hat= 5.425x + 76.406
r= 0.78598
the value of r shows a linear strong positive relationship between hours studied and test score
x=4 yhat= 98.106
Answer:
the right answer is x+1
Step-by-step explanation:
1/2x+1
therefore :
2×1/2x+1
x+1
now one denominator is x^2 + 8x + 15
if we factorise then (x +3)(x +5)
now in expressions which have like x+3 as denominator ...you multiply and divide them by x+5 and once u get denominator equal you can add numerator easily
