With an equation like this. you will try to rewrite it in slope-intercept form:y=mx+b. Therefore you will start by trying to get y by itself.
Add x to both sides to get -2y=x-10.
Then proceed to divide both sides by -2 to get y=-1/2x+(-10/-5)
Two negatives dividing will result in a positive number.
Thus, your slope intercept will be y=-1/2x+5
Three points can be (0,5), (1,9/2), and (2,4).

Answer:

a) y = 9.187 * 1.09899^x

b) 2647.2695

Step-by-step explanation:

a) using calculator, (mine is ti84 plus ce), we use stat and edit. we plug in x and y. x will be in the L1 and y wil be in L2. Now, we go to stat, calc, and we press ExpReg, short for exponential regression. we calculate and get y = 9.187 * 1.09899^x

you can round if you want. well, i guess you shouldn't, cuz it changes it dramatically

b) Now, we use y = 9.187 * 1.09899^x into the y= and we put it in whatever slot we want. Now, we press trace. we press 60 to find the y,because the number is always x. the number , y, we want is 2647.2695 recommendations.

Oki so the missing angle is also 2x + 15 since that’s equal so add all three of those together and equal it to 180 and solve
