How to tell if an equation is linear or not

1 answer:

8 0

A linear function is in the form y = mx + b or f(x) = mx + b, where m is the slope or rate of change and b is the y-intercept or where the graph of the line crosses the y axis. You will notice that this function is degree 1 meaning that the x variable has an exponent of 1.

Write the square of the binomial as a polynomial: (-1 1/3p + 6q)^2

Thepotemich [5.8K]

Answer:

$\frac{16}{9}$ p² -16pq + 36q²

Step-by-step explanation:

Given

(- $\frac{4}{3}$ p + 6q)²

= (- $\frac{4}{3}$ p + 6q)(- $\frac{4}{3}$ p + 6q)

Each term in the second factor is multiplied by each term in the first factor, that is

- $\frac{4}{3}$ p(- $\frac{4}{3}$ p + 6q) + 6q(- $\frac{4}{3}$ p + 6q)

= $\frac{16}{9}$ p² - 8pq - 8pq + 36q² ← collect like terms

= $\frac{16}{9}$ p² - 16pq + 36q²

What is the solution to the system of equations 3x+2y=39 5x-y=13

Marta_Voda [28]

3x + 2y = 39

5x - y = 13

Multiplying the last by two:

10x - 2y = 26

Adding to the first

13x = 65

x = 5

y = 5x-13 =25-13=12

Check:

3(5)+2(12)=39 good

5(5)-12=13 good

Answer: x=5, y=12
