Annie is creating a stencil for her artwork using a coordinate plane. The beginning of the left edge of the stencil falls at (2, -1). She wants to align an important detail on the left edge of her stencil at (4, 1). She knows this is 1:4 of the way to where she wants the end of the stencil. Where is the end of the stencil located? a. (12, 9)
b. (10, 7)
c. (3.5, 0.5)
d. (2.5, -0.5)

you didn't post any answer choices, so its not 100% clear what your teacher is looking for

however, log(15/7) is equivalent to log(15) - log(7)

i'm using the rule log(x/y) = log(x) - log(y)

there are 25 people coming to the party

step-by-step explanation:

the text says that there will be 22 children at this party, 1 teacher, and 2 parents. so if you add them all together (22+1+2) it will equal 25. (=25)

1/8 is left? add a bit more info plz
