Answer:
D(-2,0) E(-2,2) F(-5,2) G(-5,1)
Step-by-step explanation:
i believe that's correct
Right on top of 'a'. They'll look like one single point on the number line.
M + t + w = 19
t = 2m
w = 2m - 6
now we sub
m + (2m) + (2m - 6) = 19...combine like terms
5m - 6 = 19
5m = 19 + 6
5m = 25
m = 25/5
m = 5 <== she sold 5 books on Monday
t = 2m......t = 2(5)...t = 10 <== she sold 10 books on Tuesday
w = 2m - 6....w = 2(5) - 6....w = 10 - 6...w = 4 <== she sold 4 books on Wednesday.
Answer:
x = 12.1243557....
Step-by-step explanation:
14² = 7² + x²
Isolate x.
x² = 14² - 7²
x² = 196 - 49 = 147
√x² = √147
x = √147 = 12.1243557....
