Answer:

the answer is Equal to zero

Step-by-step explanation:

hope it's help correct me if I'm wrong <3

Answer:

≥0

Step-by-step explanation:

This one may seem tricky. The denominator is ALWAYS one more than the numerator. So, let's take a look at some examples.

-2/-1

This is >0. And even if you keep going to a number as high as -10000/-9999, it will ALWAYS be >0.

0/1

Hmm...this one is equal to 0. Seems like we have ≥0 right now.

2/3

>0, right? Well, since we have expression ≥0, that's your answer!

Can someone help me pls I’ll give brainliest to whoever is right no scam links or your getting reported only answer if you know

Answers

Answer: 3b + 125 = 157.97

Step-by-step explanation:

The two things contributing to the total cost are the cost of the bags of dog food and the adoption fee, so they need to be added together.

There are 3 bags of dog food at an unknown price, so we need to multiply 3 by an unknown value represented by the variable b.

The $125 adoption fee should be added to the price of the bags of dog food, so add 125. This creates an equation of 3b + 125 = 157.97

What is the slope of the line?

Answers

Step-by-step explanation:

you know what the slope of the line is ? it is the inclination of the line. how strongly is it going up or down, or is it maybe flat ?

in the formulas the slope is always the factor of x. the slope is excised as ratio of y coordinate change / x coordinate change when going from one point to another.

we see here 2 clear points in my opinion :

(0, -3) and (3, 0)

that is where the line crosses the y and the coordinate axis.

so, going from (0, -3) to (3, 0) :

x changes by +3 (from 0 to 3)

y changes by +3 (from -3 to 0).

so, the slope is

+3/+3 = 1

Which of the following is the equation of a line that passes through the point
(1.2) and is parallel to the x-axis?
A. y = 1
B. y = 2
C. x = 1
D. X = 2

Answers

Answer: A line that is parallel to the x-axis is a horizontal line. In this case, the horizontal line passes through a point, (1,2). All points on a horizontal line will have the same y value. Therefore, y=2  for every point on this line and that is the equation of the line.

g/(g ^ 2 + 4g) - g/((g + 4) ^ 2) =?
Simplify.

Answers

Answer:

[tex] \frac{4}{(g + 4) ^{2} }[/tex]

Step-by-step explanation:

Factor the expressions that are not already factored in g/g² + 4g.

[tex] \frac{g}{g(g + 4)} - \frac{g}{(g + 4) ^{2} } [/tex]

Cancel out g in both numerator and denominator.

[tex] \frac{1}{g + 4} - \frac{g}{(g + 4) ^{2} } [/tex]

To add or subtract expressions, expand them to make their denominators the same. Least common multiple of g+4 and (g+4)² is (g+4)². Multiply 1/g + 4 times g + 4/g + 4.

[tex] \frac{g + 4}{(g + 4) ^{2} } - \frac{g}{(g + 4) ^{2} } [/tex]

Since g + 4/(g + 4)² and g/( g + 4)⁴ have the same denominator, subtract them by subtracting their numerators.

[tex] \frac{g + 4 - g}{(g + 4) ^{2} } [/tex]

Combine like terms in g+4−g.

[tex] \frac{4}{(g + 4) ^{2} } [/tex]

Expand (g + 4)².

[tex] \frac{4}{g^{2} + 8g + 16 } [/tex]
