Which statments about the values 0.086 and 8.6 are true? A. 8.6 is 100 times more than 0.086
B. 8.6 is 1/10 of 0.086
C. 0.086 is 100 times more than 8.6
D. 0.086 is 1/100 of 8.6
E. 8.6 is 1/100 of 0.086

it is contrapositive

i could not see the question too well so check yourself again too . this is because i want you to get it correct.

hi,

the area of abcd is 245.

3*24=230

4*94=1039

2*12=24

add all of them up, you get 2450

(a) x intercepts: -6 and 2

you can obtain these by solving the equation 0=x^2 +4x-12 using your favorite quadratic formula. but it is easy to verify -6 and 2 indeed satisfy this equation.

(b) y intercept: -12

this is obtained by setting x=0: 0^2+4*0-12 = -12

(c) the minimum value is: -16 (this is the vertex)

you can get the vertex by rewriting the equation into the form:

there is no global or local maximum as the function goes to infinity, so only in the limit sense: +infinity.
