Answer:
The constant of proportionality k is given by k=y/x where y and x are two quantities that are directly proportional to each other. Once you know the constant of proportionality you can find an equation representing the directly proportional relationship between x and y, namely y=kx, with your specific k.
Step-by-step explanation:
Answer:
EF=8 FG=15
Step-by-step explanation:
EF+FG=EG
2x-12 + 3x-15 =23
5x-27 =23
5x=50
x=10
<em>Plug In:</em>
EF=8
FG=15
Answer:
1 is multipy the last term by 1/6
2 is geometric because you multiply by 2 every time.
3 is arithmitic sequence because you subtract 20 every time
Step-by-step explanation:
Answer:
3
Step-by-step explanation:
5x=15
x=3
Answer:
B
Step-by-step explanation:
The two triangles are congruent because they have three rispective side congruent
AB and AD are both radiuses and AC is in common
so m arc BC is 78 degrees
