Mrs. beaty buys sketchbooks and puzzles. each sketchbook costs $1 and each puzzle costs $3. which ordered pair represents the cost of 3 sketchbooks as the x-value and 3 puzzles as the y-value?

(3,9)
3 sketchbooks for a dollar each 3 times 1 = 3
3 puzzles for 3 dollars each 3 times 3 = 9

Answercounterclockwise rotation about the origin by 180 degrees followed by reflection about the y-axisexplanationthe given figure has verticesrecall that for counterclockwise rotation about the origin, when we rotate figure pqrs counterclockwise through an angle of 180° about the origin, the coordinates will becomenext, we reflect in the y-axis by negating the x-coordinates of the resulting figure to obtain,therefore the correct answer is c

Hello!

the answer is:

the correct option:

b.

why?

to solve the problem, we need to remember how to operate to simplify exponential expressions using the logarithms.

we are given the equation:

then, using placing logarith with base 7 on both sides of the equation, we have:

so, rounding the obtained result to two decimal places (nearest hundreth), we have:

hence, we have that the correct option:

b.

have a nice day!
