The first system of equations has infinite solutions because you can write one equation as a linear combination of the other.The second system of equations has no solution because mathematically an incoherence results -14 = -2 / 7I attach the solutions for greater understanding.
x-4y=12; 5x-20y=60 --> infinitely many
y-7x=-14; 7y-49x=-2 --> none
Answer:
m = 1 + 2log(x)/log(y)
Step-by-step explanation:
Taking logarithms, you have ...
log(x) +m·log(y) = log(y) +3log(x)
m·log(y) = log(y) +2·log(x) . . . . subtract log(x)
m = (log(y) +2·log(x))/log(y) . . . divide by the coefficient of m
m = 1 +2·log(x)/log(y) . . . . . . . simplify a bit*

* The "simplified" form will depend on your preference. Here, I like the integer 1 brought out because most logs are irrational. The result may be very slightly more accurate if we add 1, rather than log(y)/log(y)--depending on your calculator.
No it is not equivalent
please can i have a brainliest
Shorty a lil baddy
Step-by-step explanation:
She be my lil boo thang
On Monday, she read 33 pages (33 out of 100). On Tuesday, she read 40 pages (4/10 is equivalent to 40/100). On Wednesday, she read 35 pages. In total, the book is 100 pages. 33+40+35=108 pages. You cannot read 108 pages if there are only 100, so the answer is no.
