Answer:
1.1833 to 4 places of decimals.
Step-by-step explanation:
The general formula for change of base is
log_a x = log_b x / log_b a
So
log_7 10 = log_10 10 / log_10 7
= 1/ 0.845098
= 1.1833.
x²-8x=768
x²-8x-768=0
(x-32)(x+24)=0
x=32 x=-24
you use 32 because it can be negative
plug in for x
(32)(32-8)(1)=768
32×24=768
this isn't the completing the square method though this is zero product law
Line r is twice line m. i.e. r = 2s which means that they are linearly dependent.
Therefore there are infinitely many solution to the given set of equations.
8-22a
2(4-11a)
Take the largest number you can factor out of 8&22
