Hope this helps plz hit the crown:D

Answer:

B

X can be any real number, there are a lot of solutions for y = -3/2x+2 so the answer is not C or D

for a given x,y can only be y=-3/2*x+2 not any value y so the answer is not A

Since for a given x,y can only be y=-3/2*x+2 the solutions will be ~x,y = -3/2*x+2) or ~x, -3/2*x+2~ for all real numbers

A pencil holder shaped like a triangular prisms height is 12 cm, and the volume of the pencil holder is 216 cm3. What is the area of the base of the pencil holder in square centimeters

Answers

Answer:

The area of the base of the pencil holder in square centimeters is  18 square centimeters

Step-by-step explanation:

The volume of a triangular prism is given as base area X height.

To get the base area, we can quickly shuffle the order of the terms to make sure that the base area is the subject of the formula.

Base area = volume of prism / height

Base area = 216/12 = 18 square centimeters

Therefore, the area of the base of the pencil holder in square centimeters is = 18 square centimeters

Answer:

y = f(x+3) - 5.

Step-by-step explanation:

In general, the equation y = f(x-h) + k shifts the graph of f(x) h units to the right and k units upward. This graph shifts f(x) 3 units to the left (-3 units to the right) and 5 units downward (-5 units upward).

Therefore, the equation for the shifted graph is y = f(x-(-3)) + (-5), or simply y = f(x+3) - 5.

It was founded in 1812 by the Russian-American Company as an agricultural colony to feed Russian fur trappers in Alaska. With a population of 250 at its peak, Fort Ross was actually the central hub for a number of even smaller outposts as far south as Bodega Bay and the Farallon Islands, located 40 miles north and 18 miles west of San Francisco, respectively. The Russians dismantled the colony in 1841. But Mexico was still worried about the threat of Russian expansion in their land, so they invited Anglo-American settlers to California as a buffer against Russian expansion from Alaska. The Mexican government also considered inviting Chinese colonists and Irish famine refugees to California.
