The appropriate choice is ...
D: Function 1 shows a greater rate of change, because Maddy spends $20 each month and Caitlin spends $18 each month.
_____
Each time the month number in Function 1 goes up by 1, the account balance goes down by $20. Each time the month number in Function 2 goes up by 1, the account balance goes down by $18. Once you have figured out that $20 is more than $18, you know the first two answers cannot be right. The third answer is wrong because Caitlin cannot (and does not) spend -$18 each month.
Answer:
13,3,9
Step-by-step explanation:
f(3)=4(-3)-1
= -12-1
=13
f(1)=4(1)-1
= 4-1
= 3
f(5)=4(5)-11
= 20-11
= 9
Answer:
it's x=50 hope this helps
Answer:
x=5
Step-by-step explanation:
Plugin the number into sthe pythagroyean theorm (a²+b²=c²), with 3 replacing a, 4 replacing b, and x replacing c.
3²+4² = x²
9+16 = x²
25 = x²
√25 = √x²
x = 5
It's helpful to remember that if the opposite and adjacent sides of the triangle (in this case CB and AB) are the lengths 3 and 4, the hypotenuse (longest side of the triangle) is always equal to 5.
