Answer:
y=-2x+1
Step-by-step explanation:
y=Mx+b is the slope formula. You want to move y over to the other side to get the equation equal to y
9x + 4 = 58
9x = 54
x = 6
The number is 6.
When multiplying the same number raised to different powers add the powers together.
3 + 2 + 5 = 10
Because you are also multiplying a value without a power you need to add 1 to the sum of the powers:
10 + 1 = 11
Answer: 6^11
A ↔ B ↔ C ↔ D ↔ E ↔ F
8 7 ???
AB + BC + CD = AD <em>segment addition postulate</em>
+ 8 + 7 = AD
+ 15 = AD
AD + 60 = 4AD
60 = 3AD
20 = AD
AB = = = 5
DE = = = 4
CD + DE + EF = CF <em>segment addition postulate</em>
7 + 4 + EF = CF
11 + EF = CF
Answer: 11 + EF
Note: You did not provide any info about EF. If you have additional information that you did not type in, calculate EF and add it to 11 to find the length of CF.
