Describe why it might not be a good idea to use a key where each symbol stands for 1 in a picture graph

1 answer:

4 0

In a picture graph, if there is no key specified, then it is already assumed that the viewer knows that each symbol would stand for 1. If each symbol stands for more than one, then a key is required, but if each symbol stands for one, you can assume that the viewer knows.

Answer: -4/3

Step-by-step explanation:

Formula to find a slope of two given points is

y(sub2) - y(sub1) / x(sub2) - x(sub1)

Plug the values in to get the answer.

-2 - 2 / -1 - (-4)

Solve the equation with rational exponents. (x minus 1 )Superscript 2 divided by 3 Baseline equals 64

Katarina [22]

Answer:

$x=513 \Rightarrow S=\{513\}$

Step-by-step explanation:

1) Rewriting for the sake of clarity:

$(x-1)^{\frac{2}{3}}=64$

2) To solve it, we need to turn the rational exponent equal to 1 via exponent rule of product. Multiplying 2/3 by its reciprocal 3/2 we get 1, since this is an equality we need to do it on the other side.

$(x-1)^{\frac{2}{3}}=64\\\\((x-1)^{\frac{2}{3}}]^{\frac{3}{2}}=(64)^{\frac{3}{2}}\\(x-1)=\sqrt{64^{3}}\\x-1+1=512+1\\x=513$
