6 0

Answer:

Step-by-step explanation:

y−6−y−8−x4−x−5

=y+−6+−y+−8+−x4+−x+−5

Combine Like Terms:

=y+−6+−y+−8+−x4+−x+−5

=(−x4)+(−x)+(y+−y)+(−6+−8+−5)

=−x4+−x+−19

Answer:

=−x to the power of 4 minus x minus 19

Find the length of side x simplest radical form with a rational denominator

Nuetrik [128]

Answer:

The length of x in the simplest radical form with a rational denominator will be:

$x=\frac{5\sqrt{3}}{2}$

Step-by-step explanation:

Given

hypotenuse = 5

angle Ф = 60°

To determine

x = ?

Using the trigonometric ratio

cos Ф = adjacent / hypotenuse

here

Ф = 60°

adjacent of 60° = x

hypotenuse = 5

so substituting Ф = 60°, adjacent = x and hypotenuse = 5 in the equation

cos Ф = adjacent / hypotenuse

$cos\:60^{\circ }\:=\:\frac{x}{5}$

$\frac{\sqrt{3}}{2}=\frac{x}{5}$

switch sides

$\frac{x}{5}=\frac{\sqrt{3}}{2}$

Multiply both sides by 5

$\frac{5x}{5}=\frac{5\sqrt{3}}{2}$

Simplify

$x=\frac{5\sqrt{3}}{2}$

Therefore, the length of x in the simplest radical form with a rational denominator will be:

$x=\frac{5\sqrt{3}}{2}$

Solving simultaneous equations with one quadratic, x^2+y^2=16 and y=x+3

Svetlanka [38]

If $y=x+3$ , then in the first equation you have

$x^2+(x+3)^2=x^2+(x^2+6x+9)=2x^2+6x+9=16$

Rewriting a bit, you get

$x^2+3x+\dfrac92=8$

$x^2+3x+\dfrac94+\dfrac94=8$

$\left(x+\dfrac32\right)^2=\dfrac{23}4$

$x=-\dfrac32\pm\dfrac{\sqrt{23}}2$

Now, since $y=x+3$ , you also get

$y=-\dfrac32\pm\dfrac{\sqrt{23}}2+3=\dfrac32\pm\dfrac{\sqrt{23}}2$

So, there are two solutions here:

$(x,y)=\left(-\dfrac32+\dfrac{\sqrt{23}}2,\dfrac32+\dfrac{\sqrt{23}}2\right)$
$(x,y)=\left(-\dfrac32-\dfrac{\sqrt{23}}2,\dfrac32-\dfrac{\sqrt{23}}2\right)$

You've baked 26 cookies, which is two-thirds of all the cookies you planned to bake. How many cookies did you plan to make?

hodyreva [135]

Answer,

(26/2) * 3

= 39

Explanation,

26 cookies is only 2/3 of 3/3. So, we divide 26 by 2 to see how many cookies are in 1/3. We then can find out that when you make 1/3 of the cookies there are 13. Since that is only 1/3 and we want to find out 3/3. We multiply 13 by 3 and get 39 which is all the cookies she planned to make.

Hope this helps :-)
