Answer:
Step-by-step explanation:
Equation for the linear function has been given as,
y = 26 - 4x
For x = 1,
y = 26 - 4(1)
= 26 - 4
= 22
For x = 2,
y = 26 - 4(2)
= 26 - 8
= 18
For x = 3,
y = 26 - 4(3)
= 26 - 12
= 14
For x = 6,
y = 26 - 4(6)
= 26 - 24
= 2
Therefore, table for the function will be,
x y
1 22
2 18
3 14
6 2
Let sister be s. Matthew, M
Matthew is 7years older than twice the age of his sister
M = 7 + 2s
13 = 7 + 2s. 7 crosses the equality to other side and becomes -7
13 - 7 = 2s
6 = 2s Divide both sides by 2
6/2 = 2s/2
3 = s
Sister is 3 years old.
Answer:
7
Step-by-step explanation:
It has a 45 45 90 ratio, so if the hypotenuse is 7 root 2, then the two sides have to be 7.
We are given with the following:
Effective annual interest, i = 0.0425
Future worth, F = $25000
Number of years, n = 18
We use the formula to solve for the present worth of the money:
P = F / (1 + i)^n
P = 25000 / (1 + 0.0425)^18
P = 11818.73
The closest answer is:
