To rationalise multiply by its conjugate.

The conjugate of [tex]\sqrt{3}[/tex] + [tex]\sqrt{5}[/tex] is [tex]\sqrt{3}[/tex] - [tex]\sqrt{5}[/tex] then

([tex]\sqrt{3}[/tex] + [tex]\sqrt{5}[/tex] )([tex]\sqrt{3}[/tex] - [tex]\sqrt{5}[/tex] ) ← expand using FOIL

= ([tex]\sqrt{3}[/tex] )² - [tex]\sqrt{15}[/tex] + [tex]\sqrt{15}[/tex] - ([tex]\sqrt{5}[/tex] )²

= 3 - 5

= - 2

Answer:

4x - 13

Step-by-step explanation:

( 6x - 4 ) - ( 2x + 8 )

The "-" sign outside of the parenthesis is equivalent to "-", hence one can distribute the "-" sign

( 6x - 4 ) - ( 2x + 8 )

6x - 4 - 2x - 8

Combine like terms

6x - 5 - 2x - 8

4x - 13

Answer:

  u = ±√(-m/(k+r+y))

Step-by-step explanation:

Subtract r, rearrange, then take the square root.

  [tex]\dfrac{m}{u^2}+r=-k-y \qquad\text{given}\\\\ \dfrac{m}{u^2}=-k-y-r\\\\-\dfrac{m}{k+r+y}=u^2\\\\ \boxed{u=\pm\sqrt{-\dfrac{m}{k+r+y}}}[/tex]

Step-by-step explanation:

Let's solve your system by elimination.

15j+12k=18;5j+4k=6

Multiply the second equation by -3, then add the equations together.

(15j+12k=18)

−3(5j+4k=6)

Becomes:

15j+12k=18

−15j−12k=−18

Add these equations to eliminate j:

0=0

Answer:

Infinitely many solutions

Answer:

y=6x

Step-by-step explanation:

In this function, the input is the variable x. The problem says that the output is six times the input, so we will need to multiply the input by 6. To write this as a function, set the output (y) equal to 6 times the input (x):

The graph of the equation is graph (D)

The equation of the graph is given as:

[tex]y- 4 = 3(x - 1)[/tex]

Add 4 to both sides of the equation

[tex]y = 3(x - 1) + 4[/tex]

Apply the distributive property

[tex]y = 3x - 3+ 4[/tex]

Evaluate the sum of -3 and 4

[tex]y = 3x +1[/tex]

The above means that, the graph of [tex]y- 4 = 3(x - 1)[/tex] has a slope of 3 and a y-intercept of 1

Hence, the graph of the equation is graph (D)

Answer:

False

Step-by-step explanation:

When you are squaring a number, you multiply the number by itself (7*7 or 12*12), so if you were to reverse that and find the square root of the number (let's say 49), you'd have to do some guess and check and figure out which number, when multiplied with itself, would equal that number (7*7 = 49).

The square roots of a number are the number by which multiply with the same number we will get the number thus the given statement is completely False.

The number system is a way to represent or express numbers.

Any of the multiple sets of symbols and the guidelines for utilizing them to represent numbers are included in the Number b.

Consider the number 9.

The square root of it is given as,

√(9) = 3

Now, if we multiply 3 by 3 then we get 9 as,

3 x 3 = 9

If we divide 3 by 2 then 3/2 = 1.25 is not 9.

Hence "The square roots of a number are the number by which multiply with the same number we will get the number thus the given statement is completely False".

Step-by-step explanation:

Try testing each graph by picking a point on the shaded region or none shaded region.

-1/5 and 6= y-intercept

4/5 and 2= slope

You may notice that it is in y-intercept form. So to find where the shaded region goes, test a coordinate and apply it to the equation, if the answer is false, than half of the line is not where the shaded region goes.

the answer is 4 words if not 6
