X = -21

Step 1: Subtract 6 from both sides -1/3x = -7
Step 2: Divide -1/3 from both sides x = -21

The graph of the function f(x)=4/5 sqrt x is shown. What is the domain of the function?

S_A_V [24]

Answer:

All real number greater than equal to zero.

Step-by-step explanation:

The function is given by

$f(x) = \frac{4}{5}\sqrt x$

The domain is defined as the input values so that the function is well defined.

here, the values of x should be all real number and zero also.

So, the correct option is (d).

How much work is done by a man who uses a force of 7 Newtons to push a box 3 meters across the room?

ElenaW [278]

The formula to calculate work done is -

Work done ( in joule, J) = Force (in Newton) X Distance (in meters)

So, we will use the formula to calculate work done,

Here, force is given as = 7 newtons

Distance is given as = 3 meters

So, work done will be -

Work done ( in joule, J) = 7 Newtons X 3 Meters

Work done ( in joule, J) = 21 J (in joule)

4. See if you can find "like-terms" in the expression and

WITCHER [35]

Answer:

After finding like terms and solving, we get $\mathbf{3x^2+3x+16}$

Step-by-step explanation:

We need to find like terms and simplify the expression $4- 2x + x^2 + 5x + 12 + 2x^2$

Like terms: The terms who have same variable and exponent are called like terms.

So, Combining like terms and solving:

$4- 2x + x^2 + 5x + 12 + 2x^2\\=4+12-2x+5x+x^2+2x^2\\Now \ solving:\\=16+3x+3x^2\\Rearranging \ the \ terms:\\=3x^2+3x+16$

So, after finding like terms and solving, we get $\mathbf{3x^2+3x+16}$

Note: In the question given we have - and + sign with the term 5x i.e 4- 2x + x^2 -+ 5x + 12 + 2x^2

I have solved using +5x, but if the term is -5x then the solution will be:

$4- 2x + x^2 - 5x + 12 + 2x^2\\=4+12-2x-5x+x^2+2x^2\\Now \ solving:\\=16-7x+3x^2\\Rearranging \ the \ terms:\\=3x^2-7x+16$

So, the answer will be: $\mathbf{3x^2-7x+16}$
