For the fraction 28/10,
times 10 at 28 and 10,(to get the same denominator"100")
28×10=280
10×10=100

Thus,
28/10 become 280/100

We can plus the number above the denominator"100",which is 39 and 280.It is because they have achieved a same denominator.
39/100+280/100
=(39+280)/100
=319/100

The function f(x)= square root of x is translated using the rule (x, y) → (x – 6, y + 9) to create A(x). Which expression descri
Alex73 [517]

The function f(x)=\sqrt{x} is translated according to the rule

(x,y)\rightarrow (x-6,y+9).

This translation is translation 6 units to the left and 9 units up.

1. Translation of the function f(x)=\sqrt{x} 6 units to the left gives you the function g(x)=\sqrt{x+6}.

2. Translation of the function g(x)=\sqrt{x+6} 9 units up gives you the function A(x)=\sqrt{x+6}+9.

The domain of the function A(x) is [-6,\infty), then the range of the function A(x) is [9,\infty).

Answer: [9,\infty).

Serggg [28]

Answer:

b = 0.0138

Step-by-step explanation:

Given

Regression Equation:

DD=2.69+0.0138D

Required

Determine the slope of the regression line

The equation of regression is of the form

Y =  a + bX

Where b represents the slope;

Compare Y =  a + bX to the given equation

DD=2.69+0.0138D

We have that:

Y = DD

a = 2.69

b = 0.0138

X = D

Hence; the slope is:

b = 0.0138
