Suppose that the following 40-letter alphabet is used for all plaintexts and ciphertexts: a-z with numerical equivalents 0-25, blank-26, m27, ? -28, $-29, the numerals 0--9 with numerical equivalents 30- 39. suppose that plaintext message units are digraphs and ciphertext message units are trigraphs (i. e., k 2, 1 .. 3, 402

step-by-step explanation:

answer: it actually depends on which is the independent variable and which is the dependent variable. let us say we're looking at a linear equation. y=2x+3. we theoretically could switch the equation to be x=(y-3)/2 and it would be the same line. so either a causes b or it can be that b causes a. so technically the answer is false

step-by-step explanation:

cool stunts are flippin i think

sitting on a chair

and using stick feet

given the equation is 8+9z=-6, the first step would be to subtract the 8 from both sides:

8+9z-8=-6-8

since 8 minus 8 = 0, this would cancel out the 8. and since -6 minus 8 equals -14, the equation would look like this

9z = -14
