1. (2 points) the starship enterprise just picked up a strange creature called a tribble.
at first there was only one, but overnight the tribble spawned 3 more tribbles just like
it. the next night, each tribble spawned 3 more tribbles, and this continued happening
each night. how many tribbles were on the starship after the 7th night? (hint: show
that the number of tribbles follows the geometric series.)
pls y’all

21 tribbles on the 7th night

Step-by-step explanation:

every night 3 tribbles appear meaning that the tribbles spawn rate is y=3x

y= number of tribbles

x= number of nights

13

step-by-step explanation:

divide the cost of the total of sodas you bought by the cost of one soda, for example:

$24.57 divided by $1.89 is 13 which means you bought 13 sodas

so firstly, we need to isolate the y variables to be able to solve these inequalities. firstly, add 0.5x on both sides of the first inequality and subtract 1.5x on both sides of the second inequality:

now since the slope is positive for the first inequality, this means that the line going upwards belongs to the first inequality, and the line going downwards belongs to the second inequality.

next, since y ≥ in the first inequality, this means that the shaded region will be above the first inequality's line, thus shading regions a and b.

next, since y ≤ in the second inequality, this means that the shaded region is going to be below this line, thus shading regions a and c.

since both lines shade region a, this means that region a is the solution.
