aalyn [17]3 years ago
5 0

Step-by-step explanation:

{x}^{2}  =  \frac{mn + 1}{9}

(3x - 1)(3x + 1)

9 {x}^{2}  - 1

{x}^{2}  =  \frac{9 {x}^{2 } - 1 + 1 } {9}

{x}^{2}  =  \frac{9 {x}^{2} }{9}

{x}^{2}  =  {x}^{2}

So this identity is true.

Anyone help me solve for y.
riadik2000 [5.3K]

Answer:

y = - 4

Step-by-step explanation:

Given

y = 2x + ( - 2) , that is

y = 2x - 2 ← substitute x = - 1

y = 2(- 1) - 2 = - 2 - 2 = - 4

This is confirmed by the point (- 1, - 4 ) on the graph

THIS IS URGENT, IM ABOUT TO START CRYING!!!
tresset_1 [31]

PART A:

Finding the slope of the function f(x)

Choose any two pairs of coordinate from the table; (-1, -15) and (0, -10)

Let (-1, -15) be (x₁, y₁) and (0, -10) be (x₂, y₂)

Slope =

Slope of f(x) = 5

The function g(x) is given in the straight line equation form

Where,  is the slope and  is the y-intercept

Slope of g(x) = 2

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

g(x) = 2x + 8

Where, the slope (m) = 2 and the y-intercept (c) = 8

The y-intercept of g(x)  is 8

for f(x), we can read the y-intercept when x = 0.

From the table, when x = 0, y = -10

The y-intercept of f(x) is -10

Function g(x) has higher y-intercept
