Answer:

Step-by-step explanation:

To be rational means to be able to express the result as the ratio of two whole numbers.

a) 4/7 + (-1/3) = 12/21 - 7/21 = 5/21 so rational

b) √(4) • 2/5 = ±2 • 2/5 = ±4/5 so both solutions are rational

What is the slope of the following equation? 5x - 2y = 13
Mila [183]

Answer:

\frac{5}{2}

Step-by-step explanation:

5x - 2y = 13 \\ 5x - 13 = 2y \\ 2y = 5x - 13 \\ y =  \frac{5}{2} x -  \frac{13}{2}  \\ equating \: it \: with \\ y = mx + b \\ slope(m) =  \frac{5}{2}

Answer:

To create function h, function f was translated 2 units right , translated 4 units up and reflected across the x axis

Step-by-step explanation:

Given

f(x) = x^3

h(x) =-(x + 2)^3 - 4

Required

Complete chart

First: f(x) was translated right by 2 units

The rule of right translation is (x,y) \to (x + 2,y)

So, we have:

f'(x) = f(x + 2)

f'(x) = (x + 2)^3

Next: f'(x) was translated up by 4 units

The rule of down translation is (x,y) \to (x,y+4)

So, we have:

f"(x) = f'(x) +4

f"(x) = (x + 2)^3 +4

Lastly, f"(x) was reflected across the x-axis;

The rule of this reflection is: (x,y) \to (x,-y)

So, we have:

h(x) = -f"(x)

h(x) = -[(x+2)^3 + 4]

Remove bracket

h(x) = -(x+2)^3 - 4
