60'or50' just trying if I want to tryp
Im not sure why you said ur wrong b/c i got the same answer
f(x) = -15+ 7
f(x) = -8
question number one is 15 ft
question number two is 7 MI
tbh i forgot how to do the 3rd one
Answer:
2/8 OR simplified 1/4
Step-by-step explanation:
the denominators have to be the same so you multiply 1/4 by 2 so you get 2/8. Then its 4/8-2/8 so you get 2/8 as your answer
Looking at the equation, you could see that it is in vertex form. Vertex form looks like this: y=a(x-h)^2+k where a is the slope to find the first point away from the origin and (h,k) is the vertex. So, the vertex is (3,-1). The first point away from the origin is up two, over one, so the slope is 2. This means that a is 2. One way you could check this is by putting 2 in for a. If you put it into standard form, it would be 2x^2-12x+17. To find the x in the vertex when the equation is in standard form we use -b/2a. So it would give us 3 for x. If we put in 3 for x, we get -1 for y, so the vertex is (3,-1). This means that a is 2. Sorry for this lengthy answer, hope it helps.
