For each equation, tell whether or not it defines a linear function, and explain how you know.
alekssr [168]
A linear function is usually in the form: y=Mx+c. In equation 1, there is no x term and same for equation 3, leaving your only and correct answer to be equation 2. And if you rearrange equation 2, you will get: 5y = -2x + 8.

Jack is 3 times a as old as lacy. 8 years ago the sum of their ages was 25. how old are they now?
OlgaM077 [116]


Let x = age of jack

Let y = age of Lacy

x=3y (Jack age is 3 times that of Lacy)

(x+y)-8 = 25

Substituting value of x:

(3y+y) -8 = 25

4y - 8 = 25

4y = 33

y = 33/4 = 8.25 or 8 years 3 months (age of Lacy)

x = 3(8.25) = 24.75 or 24 years 9 months (age of Jack)

Checking:

Substituting in equation ( x + y ) -8 = 25

24.75 + 8.25 - 8 = 25

25 = 25

Find the common difference and the next three terms of the arithmetic sequence. 1/4,1/2,3/4,1,5/4
andriy [413]

Hi there! :)

Answer:

\large\boxed {\frac{1}{4}} Common difference

\large\boxed{\frac{3}{2}, \frac{7}{4}, 2} Next three terms

- - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - -

Find the common difference by subtracting the previous term from a term. We can use the terms 1/4 and 1/2:

Convert 1/2 into a fraction over 4:

1/2 · 2/2 = 2/4

Find the common difference by subtracting the fractions:

2/4 - 1/4 = 1/4. This is the common difference.

Find the next 3 terms by adding 1/4:

5/4 + 1/4 = 6/4 (Reduce fraction) = 3/2

6/4 + 1/4 = 7/4

7/4 + 1/4 = 8/4 (Reduce fraction)

Therefore, the next 3 terms are 3/2, 7/4 and 2.
