Answer:

[tex]Y' = (-2, 4\frac{2}{3})[/tex]

Step-by-step explanation:

Given

[tex]Y = (-3,7)[/tex]

[tex]Scale\ Factor = (\frac{2}{3}x,\frac{2}{3}y)[/tex]

Required

Determine Y'

Y' can be solved by multiplying the scale factor by Y

i.e.

[tex]Y' = Scale\ Factor * Y[/tex]

For, the x coordinates.

[tex]Y' = \frac{2}{3}x[/tex]

Where

[tex]x = -3[/tex]

[tex]Y' = \frac{2}{3} * -3[/tex]

[tex]Y' = \frac{-6}{3}[/tex]

[tex]Y = -2[/tex]

For the y coordinates:

[tex]Y' = \frac{2}{3}y[/tex]

Where

[tex]y = 7[/tex]

[tex]Y' = \frac{2}{3} * 7[/tex]

[tex]Y' = \frac{14}{3}[/tex]

[tex]Y' = 4\frac{2}{3}[/tex]

Hence:

[tex]Y' = (-2, 4\frac{2}{3})[/tex]

Answer:

Multiple the first equation by -1

Step-by-step explanation:

After doing this you add the two equations together and follow the systems of equations as normal

[tex]-3x+-5y=-16\\3x+2y=10\\-3y=-6\\\frac{-3y}{-3} =\frac{-6}{-3} \\y=2[/tex]

Therefore y = 2

Answer:

Once an expression has been factored, use the Distributive Property to expand the expression. The expanded expression should be the original expression.

Step-by-step explanation:

The distributive property for any binary operation Ф under * in the given set S where a, b, c ∈ S

The binary operation a * (b Ф c) = (a * b) Ф (a * c) .

The operation * distributes over the operation Ф.

Now, when factoring, suppose we have an expression ab + ac. To factor this, we have a(b + c).

To check that our answer is correct, since the expression has been factored, we then distribute the multiplication over the addition to check if the factorization is correct.

So, a(b + c) = ab + ac which is our initial expression.

So, to use the distributive property to check work when factoring, once an expression has been factored, use the Distributive Property to expand the expression. The expanded expression should be the original expression.

The way to use the Distributive Property to check your work when factoring is;

Option D; Once an expression has been factored, use the Distributive Property to expand the expression. The expanded expression should be the original expression.

The distributive property in algebra is expressed as; a(b + c) = ab + ac

Now, to use the distributive property to check the work when factoring, we have to expand the factored form first.

For example, we have; 2(3 + 4)

From distributive property, we have;

(2 × 3) + (2 × 4) = 14

This should be the same with the original factored expression; 2(7) = 14

Thus, the method is Once an expression has been factored, use the Distributive Property to expand the expression. The expanded expression should be the original expression.

Answer:

75 small triangles

Step-by-step explanation:

1. Reduce the ratio: 2-6 = 1-3

2. Write each of them as a fraction of a whole:

 Small total = 3/(1+3) = 3/4 of the total amount

3. Multiply the ratio to get the answer: 3/4 * 100 = 75

Answer:

8x^2-6a+9b+14

Step-by-step explanation:

P=(12a^2 + 5a + 9b + 16)

(4a^2 + 9a - 8)+ (2a + 2b + 10) +(x)= (12a^2 + 5a + 9b + 16)

(4a^2+11a+2)+(x)=(12a^2 + 5a + 9b + 16)

subtract (4a^2+11a+2) from both sides

x= 8x^2-6a+9b+14

76.1

Step-by-step explanation:

y = ice cream

z = Tempreature

y = 1.8(85) - 76.9

1.8(85) = 153

153 - 76.9 = 76.1

Answer:

76

Step-by-step explanation:

y = 1.8(85) - 76.9

y = 153 - 76.9

y = 76.1

and when you round to the nearest whole number,

y = 76

Answer:

120+ 4(square root)15

120+15.49=135.49

135.49 is the perimeter

The perimeter of the triangle having two angles 60 degrees, 60 degrees, and one side [tex]4\sqrt{15}[/tex] is, [tex]12\sqrt{15}[/tex] or 46.47

Perimeter is a mathematical term, which means total outer boundary of a figure, we define it only for two dimensional figures.

Perimeter = Sum of length of the all the sides

Given that,

the triangle having two angles 60 degrees, 60 degrees,

and one side

It is known that, total sum of all the angles of triangle is 180°

A = 60°

B = 60°

C = ?

A + B + C = 180°

60° + 60° + C =  180°

C =60°

Hence, it is a equilateral triangle

And for equilateral triangle length of all sides are equal

a =  [tex]4\sqrt{15}[/tex]

b =  [tex]4\sqrt{15}[/tex]

c =   [tex]4\sqrt{15}[/tex]

Perimeter =  [tex]4\sqrt{15}[/tex] +  [tex]4\sqrt{15}[/tex] +  [tex]4\sqrt{15}[/tex]

Perimeter = 12√15

So, the perimeter is 12√15

The instantaneous velocity at t = 1 will be:

Step-by-step explanation:

Given the position of an object at a time [tex]t[/tex]

[tex]s\left(t\right)=-8-9t[/tex]

As we know that determining the derivative of the position function with respect to time t would give us the instantaneous velocity, so

[tex]\frac{ds}{dt}=\frac{d}{dt}\left(-8-9t\right)[/tex]

Applying the sum/difference rule:

[tex]\left(f\pm g\right)'=f\:'\pm g'[/tex]

[tex]\frac{ds}{dt}=-\frac{d}{dt}\left(8\right)-\frac{d}{dt}\left(9t\right)[/tex]

as

[tex]\frac{d}{dt}\left(8\right)=0[/tex]    ∵ [tex]\frac{d}{dx}\left(a\right)=0[/tex]

and

[tex]\frac{d}{dt}\left(9t\right)=9[/tex]   ∵ [tex]\mathrm{Take\:the\:constant\:out}:\quad \left(a\cdot f\right)'=a\cdot f\:'[/tex]  and [tex]\frac{d}{dt}\left(t\right)=1[/tex]

so the expression becomes

[tex]\frac{ds}{dt}=-\frac{d}{dt}\left(8\right)-\frac{d}{dt}\left(9t\right)[/tex]

   [tex]=-0-9[/tex]

   [tex]=-9[/tex]

As the derivative is constant.

Therefore, the instantaneous velocity at t = 1 will be:
