Answer:

Step-by-step explanation:

The point-slope form of the equation is y - y₀ = m(x - x₀), where (x₀, y₀) is any point the line passes through and m is the slope:

m = -1

(-5, 5) ⇒ x₀ = -5, y₀ = 5

The point-slope form of the equation:

y - 5 = -1(x + 5)

So:

y - 5 = -x - 5 {add 5 to both sides}

y = -x ← the slope-intercept form of the equation

Can someone please help me

Rzqust [24]

Answer:

the graph of the function is non-linear

the table can be represented by the equation y=4x+4

Step-by-step explanation:

non linear because 1+7=8 and then 10+2 = 12 so they have different numbers to add each time

represented by the equation because the x numbers (1,2,3,4,) all multiplied by 4 and added by 4 gives you y

any more help just ask :)

Jennifer needs to make an average of at least $350 per week. If she makes $385, $326, and $298 for the first 3 weeks of the mont

ella [17]

385 + 326 + 298 = 1,009 / 3 = 336.33

385 + 326 + 298 + x = 350

350 x 4 = 1,400
1,400 - 1,009 = 391

385 + 326 + 298 + 391 = 1,400 / 4 = 350

The answer is $391

Given the graph of a function f. Identify the function by name. Then Graph, state domain & range in set notation:A) f(x) +2B

WARRIOR [948]

The function in the graph has the name of square function.

The domain of a function is all values of x the function can have. The domain of this function is all real numbers:

$\mleft\lbrace x\in\R\mright\rbrace$

The range of a function is all values of y the function can have. The range of this function is all positive numbers, including zero:

$\mleft\lbrace y\in\R\mright|y\ge0\}$

In order to graph f(x) + 2, we just need to translate the graph 2 units up. To find the new points, we need to increase all y-coordinates by 2:

(-2, 6), (-1, 3), (0, 2), (1, 3), (2, 6)

Domain: {x ∈ ℝ}

Range: {y ∈ ℝ | y ≥ 2}

Then, in order to graph f(x) - 2, we just need to translate the graph 2 units down. To find the new points, we need to decrease all y-coordinates by 2:

(-2, 2), (-1, -1), (0, -2), (1, -1), (2, 2)

Domain: {x ∈ ℝ}

Range: {y ∈ ℝ | y ≥ -2}
