Answer:
a. 12/13
Step-by-step explanation:
Sin is opposite over hypotenuse.
Opposite side of K is 12 and your hypotenuse is 13
So to estimate, I would look at each set of numbers and determine which ones have higher numbers. For example in the first set the highest I see is 12x5=60
In the second set I see 14 AND 16 automatic telling me to estimate that Destiny has more using 14x4=56, but keeping in mind there is a 16 as well...
Answer:
where is the graph. without it i cannot answer your question
Step-by-step explanation:
A) Jamar rewrote the first equation as -2x + 10y = -4. He had justification for doing this because he multiplied all parts of the expressions on both sides of the equation by the same factor, -2.
B) Jamar combined -2x + 10y = -4 with the other equation, 3x-10y=11, to get x=7. To do this, Jamar used combination, combining each of the different parts of the equations together. The y variables cancel out, and the x variables leave 1x, and we subtract 4 on the right side of the equation, leaving x = 7.
C)The solution of the system in an ordered pair (x,y) is (7, -1). You can get the y variable by substituting the x variable that we know equals 7, back into either of the beginning equations, to get the y value.
D) You know, without graphing, that the graph of 4x-15y=13 passes through the point whose coordinates are the solution of the system, because if we plug in the ordered pair (7,-1) into the equation it is a true statement, meaning that the variables are a solution this equation too. Therefore, if it <em>were</em> to be graphed, it would go through the point (7, -1).
