Answer:

(6, - 9 )

Step-by-step explanation:

Given the 2 equations

6x + 2y = 18 → (1)

- 4x - 2y = - 6 → (2)

Adding the 2 equations term by term will eliminate the y- term, that is

2x + 0 = 12

2x = 12 ( divide both sides by 2 )

x = 6

Substitute x = 6 into either of the 2 equationsand solve for y

Substituting into (1)

6(6) + 2y = 18

36 + 2y = 18 ( subtract 36 from both sides )

2y = - 18 ( divide both sides by 2 )

y = - 9

solution is (6, - 9 )

Answer:

(8, 2 )

Step-by-step explanation:

Given the 2 equations

x + 4y = 16 → (1)

- x + 3y = - 2 → (2)

Adding the 2 equations term by term will eliminate the x- term

0 + 7y = 14

7y = 14 ( divide both sides by 7 )

y = 2

Substitute y = 2 into either of the 2 equations and solve for x

Substituting into (1)

x + 4(2) = 16

x + 8 = 16 ( subtract 8 from both sides )

x = 8

solution is (8, 2 )

Answer:

y = 10√16) = 40

Step-by-step explanation:

This says, "y is proportional to the square root of x."  We are told that y = 60 when x = 36.  Find the formula for this function.  Then, determine what value y will take on when x = 16.

y = k√x  becomes 60 = k√36, or 60 = 6k.  Then k must be 10, and the formula is y = 10√x.

If x = 16, y = 10√16) = 40

The zeros for the function

[tex]x=6,\:x=4i,\:x=-4i[/tex]

Step-by-step explanation:

Given the expression

[tex]y=x^3-6x^2+16x-96[/tex]

Plug in y = 0 to determine all the zeros

[tex]x^3-6x^2+16x-96=0[/tex]

as

[tex]x^3-6x^2+16x-96=\left(x-6\right)\left(x^2+16\right)[/tex]

so the expression becomes

[tex]\left(x-6\right)\left(x^2+16\right)=0[/tex]

Using the zero factor principle

if ab=0, then a=0 or b=0 (or both a=0 and b=0)

[tex]x-6=0\quad \mathrm{or}\quad \:x^2+16=0[/tex]

solving

[tex]x-6=0[/tex]

[tex]x = 6[/tex]

solving

[tex]x^2+16=0[/tex]

subtract 16 from both sides

[tex]x^2+16-16=0-16[/tex]

[tex]x^2=-16[/tex]

[tex]\mathrm{For\:}x^2=f\left(a\right)\mathrm{\:the\:solutions\:are\:}x=\sqrt{f\left(a\right)},\:\:-\sqrt{f\left(a\right)}[/tex]

[tex]x=\sqrt{-16},\:x=-\sqrt{-16}[/tex]

as

[tex]x=\sqrt{-16}[/tex]

[tex]\sqrt{-16}=\sqrt{-1}\sqrt{16}[/tex]

as

[tex]\sqrt{-1}=i[/tex]

so

[tex]x=4i[/tex]

and

[tex]x=-\sqrt{-16}[/tex]

[tex]-\sqrt{-16}=-\sqrt{-1}\sqrt{16}[/tex]

as

[tex]\sqrt{-1}=i[/tex]

so

[tex]x=-4i[/tex]

Thus, the zeros for the function

[tex]x=6,\:x=4i,\:x=-4i[/tex]

Answer:

270

Step-by-step explanation:

Given that :

Ratio = 14:8:5

Houses : flats : bungalow

Number of bungalow = 50

Sum of ratio = (14 + 8 + 5) = 27

Let total number of households = x

Bungalow = 5/27 * x

5/27 * x = 50

5x / 27 = 50

5x = 50 * 27

5x = 1350

x = 1350 / 5

x = 270

Number of places to live = 270

Answer:

m = 28

Step-by-step explanation:

The given expression is :

0.1(0.5m+6)=2

Step 1.

Use distributive property:

0.1(0.5m) +0.1(6) = 2

0.05 m+ 0.6 = 2

Step 2.

Subtract 0.6 both sides

0.05 m+ 0.6 -0.6= 2 -0.6

0.05 m = 1.4

or

0.5 m = 14

Step 3.

Divide both sides by 0.5

[tex]m=\dfrac{14}{0.5}\\\\m= 28[/tex]

Gabi's third step is not correct. It should be m = 28 instead of m = 7.

Step-by-step explanation:

Answer:

On the surface, it seems easy. Can you think of the integers for x, y, and z so that x³+y³+z³=8? Sure. One answer is x = 1, y = -1, and z = 2. But what about the integers for x, y, and z so that x³+y³+z³=42?

That turned out to be much harder—as in, no one was able to solve for those integers for 65 years until a supercomputer finally came up with the solution to 42. (For the record: x = -80538738812075974, y = 80435758145817515, and z = 12602123297335631. Obviously.)

Answer: See explanation

Step-by-step explanation:

My friends calculation is wrong. 40% of 80 is not 200. It is:

= 40% of 80

= 40/100 × 80

= 0.4 × 80

= 32

He should have represented the missing number by x. Therefore,

40/100 = 80/x

Cross multiply

(40 × x) = (80 × 100)

40x = 8000

x = 8000/40

x = 200

The value of x and y in the given model of triangle are 4 and 28 respectively.

An equilateral triangle is a triangle in which all sides are equal and angles are also equal. The value of each angle of an equilateral triangle is 60°.

Given a tortilla chips that can be modelled as a triangle,

The sides and angles are labelled equal, so the given chips is an equilateral triangle

6x+3 = 27

6x = 24

x = 4

And, 2y+4 = 60°

2y = 56

y = 28

Hence, The value of x and y in the given model of triangle are 4 and 28 respectively.
