Answer:
Im taking this right now so Im not 100% sure
Step-by-step explanation:
y-intercept: 2 because the slope is passing through 2.
slope: take points (-1,2) and (-1,3)
m=Y2-Y1/X2-X1
m=3-2/-1-1
m=-1/2 or 1/-2(there is no difference)
so the slope is -1/2
b=2
in slope intercept, its going to be:y=-1/2x+2
btw, i noticed that the point isn't -1 it's 0.75 i think. Substitute the -1 for -0.75(-3/4) and finish the math. Sorry.
If three consecutive values add to 567 the middle value must be 567/3 = 189
Since the values are multiples of 9, the other values must be 189 - 9 and 189 + 9
The three values are 180, 189, 198
Answer:
See below
Step-by-step explanation:
I'll provide an example to help you. Let's say we were solving and we wanted to factor the quadratic on the left side. We can't do that because the factors of -7 don't add up to 5. So we'd have to use the quadratic formula. The quadratic formula is essentially the last resort that will solve all quadratic equations, so it could be seen as a preferred method. But, unless you can factor the quadratic, it's much easier to solve.
Now let's do another one. for example can be written as and we can easily get and as solutions since plugging them into the factors would produce 0 (from the Zero Product Property). If we used the quadratic formula, it would take more time to plug in the variables and solve when we can just simply factor.
Hopefully, this explanation helps you to think of your discussion post!
The quotient is 28/30 and the simplified versions is 14/15
