Answer:
First One: Yes
Second One: No
Step-by-step explanation:
Direct Variation Formula: y=kx
1. every single on is y=x times 6, fits the formula
2. there is no easy multiplying repeating pattern of how x=y
Answer:
9.8
Step-by-step explanation:
14^2-10^2 =196-100=96
sqrt(96)~9.8
Answer:
a. The slope m is 0.02
b. The initial value b is 250
c. y = 0.02x + 250
d. His weekly income is $262 if the sales were $600.00
Step-by-step explanation:
the form of the linear equation is y = m x + b, where
- m is the slope (rate of change)
- b is the y-intercept (constant amount)
∵ A real estate sales agent receives a salary of $250 per week
→ This is a fixed amount every week
∴ b = 250
∵ They give a commission of 2% of sales
→ This value depends on the sales (rate of change)
∵ 2% = 2 ÷ 100 = 0.02
∴ m = 0.02
a. The slope m is 0.02
b. The initial value b is 250
∵ y represents the weekly income
∵ x represents the sales
∵ m = 0.02 and b = 250
∴ The equation is y = 0.02x + 250
c. y = 0.02x + 250
∵ The sales were $600.00
∴ x = 600
→ Substitute it in the equation to find y
∵ y = 0.02(600) + 250
∴ y = 12 + 250
∴ y = 262
d. His weekly income is $262 if the sales were $600.00
Answer:
The first term is 2.5
Step-by-step explanation:
The first term is 2.5 and it decreases 0.5 each time.
x= -0.5n+2.5
