Answer:
Angles of a quadrilateral add up to 360
so x+36+72+144=360
x+252=360
x=360-252
x=108
So B is the correct answer
Step-by-step explanation:
Answer:
when x=0 y=7
when x=-1 y= 6
Step-by-step explanation:
to find x & y we can make the two x expressions equal to each other
x²+2x+7=7+x (we are going to set it equal to zero to find the roots/the x value)
x²+x=0
x(x+1)=0
x=0 x=-1 (two solutions for x)
now we just plug in these values and find the y values
when x=0 y=7
when x=-1 y= 6
Answer:
C=0.75m+3
Step-by-step explanation:
3=flat fee
0.75 per mile
m=mile
c=cost
6. d
7. a
8. f
9. b
10. c
11. (7x3)+(7x2)=
21+14=35
7x5=35
12. (6x3)+(6x3)=
18+18=36
6x6=36
13. (2x3)+(6x3)=
6+18=24
8x3=24
14. (9x5)+(9x3)=
45+27=72
9x8=72
