Answer:

The new coordinates are:

Please check the attached graph.

Step-by-step explanation:

We know that when an object is dilated by a scale factor, it gets reduced, stretched, or remains the same, depending upon the value of the scale factor.

If the scale factor > 1, the image is enlarged

If the scale factor is between 0 and 1, it gets shrunk

If the scale factor = 1, the object and the image are congruent

Given the vertices of the triangle in the diagram

A (1, 4)

B(2, 2)

C(-2, 1)

In our case:

Rule to calculate the dilation by a scale factor 6 centered at the origin

P(x, y) → P'(6x, 6y)

Here, P'(6x, 6y) ) is the image of P(x, y).

Thus,

A (1, 4)  → A'(6(1), 6(4))  → A'(6, 24)

B(2, 2)  → B'(6(2), 6(2))  → B'(12, 12)

C(-2, 1) → C'(6(-2), 6(1))  → C'(-12, 6)

Therefore, the new coordinates are:

Answer:

60

Step-by-step explanation:

Answer:

A

Step-by-step explanation:

Given :

2x + 4y = 14  ---------- eq 1

4x + y = 20 ---------- eq 2

if you multiply eq 2 by -4 on both sides, you get

-4 (4x + y = 20) = -4 (20)

-16x -4y = -80 --------- eq3

we can see that eq. 1 and eq 2 together forms the system of equations presented in option A, Hence A is equvalent to the orginal system of equations given in the question.

The system of equations which is equivalent to the [tex]2x + 4y = 14[/tex],[tex]4x + y = 20[/tex]  is given in option [tex](A)[/tex] i.e. [tex]2x + 4y = 14[/tex] and [tex]-16x - 4y = -80[/tex].

System of equations comprises of two or more equations and seeks common solutions to the equations.

We have,

[tex]2x + 4y = 14[/tex]   [tex]........(i)[/tex]

  [tex]4x + y = 20[/tex]    [tex]........(ii)[/tex]

Now,

To check that which option suits best for system of equation,

Lets multiply equation [tex](ii)[/tex] by [tex](-4)[/tex],

  [tex](-4) (4x + y) = (-4)*(20)[/tex]

[tex]-16x-4y=-80[/tex],

So, this above obtained equation is in option  [tex](A)[/tex].

Hence, we can say that the system of equations which is equivalent to the [tex]2x + 4y = 14[/tex] ,[tex]4x + y = 20[/tex] is given in option [tex](A)[/tex] i.e. [tex]2x + 4y = 14[/tex] and [tex]-16x - 4y = -80[/tex].

Answer:

[tex]-\frac{1}{2}[/tex]

Step-by-step explanation:

"The sum of 8 times a number (x) and 7 equals 3."

Let, "a number" = x

8x + 7 = 3

Isolate the variable, x. Note the equal sign, what you do to one side, you do to the other. Do the opposite of PEMDAS.

PEMDAS is the order of operation, and equals:

Parenthesis

Exponents (& Roots)

Multiplication

Division

Addition

Subtraction.

First, subtract 7 from both sides of the equation:

8x + 7 (-7) = 3 (-7)

8x = 3 - 7

8x = -4

Next, divide 8 from both sides of the equation:

(8x)/8 = (-4)/8

x = -4/8

x = -1/2

-1/2 is your number, or -0.5

Answer: 840 people

Step-by-step explanation:

They surveyed 40 people in total and out of those 40, 21 said that sausage pizza was their favorite pizza.

The percentage of people who prefer sausage pizza is therefore:

= 21/40 * 100%

= 52.5 %

If there are 1,600 people in the festival and we assume that the sample is a representation of the people there, the estimated number of people who prefer sausage pizza will be:

= 52.5% * 1,600

= 840 people

Answer:

Nickel = 13

Dimes = 8

Quarters = 16

Step-by-step explanation:

Let N denote Nickel,

Let D denote dime

Let Q denote quarter

Now, from online conversions;

1 nickel = 5 cents

Also, 1 dime = 10 cents

Also, 1 quarter = 25 cents

Isabelle has $5.45 which is also 545 cents.

Thus, we have;

5N + 10D + 25Q = 545 - - - (eq 1)

We are told that;

she has five more nickels than dimes, and twice as many quarters than dimes.

Thus;

N = D + 5

Also, Q = 2D

Plugging them for N and Q in eq 1 givens;

5(D +5) + 10D + 25(2D) = 545

5D + 25 + 10D + 50D = 545

25 + 65D = 545

65D = 545 - 25

65D = 520

D = 520/65

D = 8

Thus; N = D + 5 = 8 + 5 = 13

Q = 2D = 2 × 8 = 16

Answer:

X=-1

Y=1

Solve using Elimination.

Step-by-step explanation:

Multiply the second equation by 7.

The two equations are now:

7x+6y=-1

-7x +14y=21

Combine the two equations

7x and -7x cancel each other out, 14y+6y is 20y, and 21 - 1 is 20.

The equation is now

20y=20, divide 20 on both sides to get Y=1.

Now, substitute 1 as Y in the second equation for -x+2(1)=3

-x+2=3, can be simplified, by subtracting 2 from both sides. Giving us

-x=1.

Divide both sides by -1 for X=-1

Final answers being X=-1, Y=1
