What does this mean I don't understand sorry I can't help!
Answer:
Maya messed up on Step 1, David messed up on Step 2
Step-by-step explanation:
Maya:
Step 1 should distribute to 5x - 15 = 12
David:
Step 2 should be 3x - 2x = -2 - 3 after you combine like terms
The answer:
the main formula for computing the multiplicative rate of change is given by:
Mutiplicative Rate of Change = [f(x2)/f(x1)] / (x2 -x1)
this formula can be written as
[f(x2)/f(x1)] / (x2 -x1) = [f(x2) * (x2 -x1) /f(x1)]
for example we can take (x1, f(x1))= (0, 2) and (x2, f(x2))= (1, 5)
therefore,
Mutiplicative Rate of Change = [5/2] / (1-0)= 5/2= 2.5
the answer is 2.5
Answer:
12
Step-by-step explanation:
4-2x=-18
-4 -4
-2x=-24
-2 -2
x=12
The value of x is given by the pythagoras theorem
X^2 = 17^2 - 15^2
X^2 = 289-225
X^2 = 64
X = sqrt64
X= 8cm
