Answer:
a
Step-by-step explanation:
substitute n = 5 into the explicit formula , then
a₅ = 4 + (5 + 1)(- 5) = 4 + 6(- 5) = 4 - 30 = - 26
Answer:
-9
Step-by-step explanation:
1−15−(−5)
−14−(−5)
−9
The slope is -1/2x in this case because it is always next to a variable y=mx+b.
“10 more that” means “add 10 to something”
“twice” means “multiply something by 2”
Use “x” or another variable for “a number”
Twice a number: 2*x or 2x
10 more than twice a number: add 10 to 2x
Answer: 2x+10
This is simply testing if proportions are valid.
Guess-and-check, so the answer would be 40:48, since 5 x 8 = 40 and 6 x 8 = 48, where 8 is the set "constant" number
