Simplify the equation 28st/-4t

Mathematics
1 answer:
Gnoma [55]3 years ago
7 0

We can simplify both the numeric and literal parts.

It could be useful to rewrite the fraction as follows, to make clear what we're simplifying with what:

\dfrac{28st}{-4t} = -\dfrac{7\cdot 4}{4}\cdot s \cdot \dfrac{t}{t}= -7\dfrac{4}{4}\cdot s \cdot \dfrac{t}{t}

The fractions 4/4 and t/t simplify to 1, since the numerator and denominator are the same. So, we're left with

\dfrac{28st}{-4t} =-7s

If f(x) =-2+8 and g(x) = square root of x+9 which statement is true
lidiya [134]

The statement that -6 is in the domain of f(g(x)) is true

<h3>Complete question</h3>

If f(x) = -2x + 8 and g(x) = \sqrt{x + 9, which statement is true?

  • -6 is in the domain of f(g(x))
  • -6 is not in the domain of f(g(x))

<h3>How to determine the true statement?</h3>

We have:

f(x) = -2x + 8

g(x) = \sqrt{x + 9

Start by calculating the function f(g(x)) using:

f(g(x)) = -2g(x) + 8

Substitute g(x) = \sqrt{x + 9

f(g(x)) = -2\sqrt{x + 9} + 8

Set the radicand to at least 0

x + 9 \ge 0

Subtract 9 from both sides

x \ge -9

This means that the domain of f(g(x)) are real numbers greater than or equal to -9. i.e. -9, -8, -7, -6, ...........

Hence, the statement that -6 is in the domain of f(g(x)) is true

Is (2, 3) a solution to the inequality y &gt; 6x + 3?
Sindrei [870]

Good morning

Answer:

NO

Step-by-step explanation:

Here we just substitute x and y by their values and see if the inequality still true or not

y = 3

6x + 3 = 6(2) + 3 = 15

since 3 < 15 then the inequality y > 6x + 3 is wrong.

What is the slope OF THE GRAPH, not what is A slope, what is THE slope
Oksanka [162]

Answer:

-3/1

Step-by-step explanation:

The slope can be found by putting the rise over the run.  

Pick 2 points on the graph that intercept the line.

I'll pick (0,2), and (1,-1)

Look at the rise.(How many places it goes up or down)

The rise vertical distance(rise), between the two points is -3.

Now look at the run(the horizontal distance.)  It's 1.

Rise/Run =  -3/1  AKA -3

If the equation of a function is y = x2 – 5, what is the output when the input is -1?
Nimfa-mama [501]
The input is the y
y = x^2 - 5
plug in what we're given
-1 = x^2 -5
add 5 to both sides
4 = x^2 
take the square root of both sides
2 = x

Hope this helps :)
