Answer:

1. Multiply (2) by 2 to eliminate the x-terms when adding

2. Multiply (2) by 3 to eliminate the y- term

Step-by-step explanation:

Use this system of equations to answer the questions that follow.

4x-9y = 7

-2x+ 3y= 4

what number would you multiply the second equation by in order to eliminate the x-terms when adding the first equation?

4x-9y = 7 (1)

-2x+ 3y= 4 (2)

Multiply (2) by 2 to eliminate the x-terms when adding the first equation

4x-9y = 7

-4x +6y = 8

Adding the equations

4x + (-4x) -9y + 6y = 7 + 8

4x - 4x - 3y = 15

-3y = 15

y = 15/-3

= -5

what number would you multiply the second equation by in order to eliminate the y- term when adding the second equation?

4x-9y = 7 (1)

-2x+ 3y= 4 (2)

Multiply (2) by 3 to eliminate the y- term

4x - 9y = 7

-6x + 9y = 12

Adding the equations

4x + (-6x) -9y + 9y = 7 + 12

4x - 6x = 19

-2x = 19

x = 19/-2

= -9.5

x = -9.5

Answer:

We have a small circle, that is dilated by a factor of 5/3 creating a larger circle.

If the smaller circle has a diameter D, then after the dilation, the larger circle will have a diameter equal to: (5/3)*D

We know that the area of the larger circle is:

A = 100*pi cm^2.

And the area of a circle of diameter d, is:

a = pi*(d/2)^2

knowing that the diameter of the large circle is (5/3)*D, we can find the value of D.

A = pi*( (5/3)*D/2)^2 = 100*pi cm^2

let's solve this for D:

pi*( (5/3)*D/2)^2 = 100*pi cm^2

( (5/3)*D/2)^2 = 100 cm^2

( (5/3)*D/2) = √(100 cm^2) = 10cm

D/2 = (3/5)*10cm

D = 2*(3/5)*10cm = 12cm.

Then the area of the smaller circle will be:

a = pi*(D/2)^2 = pi*(12cm/2)^2 = pi*(6cm)^2 = pi*36 cm^2

and pi = 3.14

a = pi*36 cm^2 = 3.14*36cm^2 = 113.04 cm^2

Answer:

1634 and 142

Step-by-step explanation:

y+x=1776

- (y-x=1492)

equals:

2x=284

÷2 ÷2

x=142

y+142=1776

-142 -142

y=1634

First number and second number are 1,634 and 142.

Given that;

Difference of two number = 1,492

Sum of two number = 1,776

Find:

The numbers

Computation:

Assume numbers are 'a, b'

So,

a + b = 1776  ...... eq1

a - b = 1492  ...... eq2

Eq 1 - Eq2

2b = 284

b = 142

a + b = 1776

a + 142 = 1776

a = 1,634

Answer:

[tex]\displaystyle h=-\frac{1}{6}x^2+2x[/tex]

Step-by-step explanation:

We are given that the height of the tunnel is modeled by:

[tex]h=rx^2+tx[/tex]

Where r and t are constants.

We are also given that the maximum height of the tunnel h is six meters.

And at ground level, the width is 12 meters.

And we want to determine the equation of the parabola.

First, since this is a quadratic, our maximum height h will occur at the vertex of our equation.

Recall that the vertex is given by the formulas:

[tex]\displaystyle \text{Vertex} = \left(-\frac{b}{2a}, f\left(-\frac{b}{2a}\right)\right)[/tex]

In our case, we have the function:

[tex]h=(r)x^2+(t)x[/tex]

Hence, a = r; b = t; and c = 0.

Therefore, the x-coordinate of our vertex is:

[tex]\displaystyle x = -\frac{t}{2r}[/tex]

Therefore, if we substitute this back into our equation, the result should be six since six is the maximum height. Hence:

[tex]\displaystyle (6)=r\left(-\frac{t}{2r}\right)^2+t\left(-\frac{t}{2r}\right)[/tex]

Simplify:

[tex]\displaystyle 6=r\left(\frac{t^2}{4r^2}\right)-\frac{t^2}{2r}[/tex]

Simplify:

[tex]\displaystyle 6=\frac{t^2}{4r}-\frac{t^2}{2r}[/tex]

Subtract:

[tex]\displaystyle 6=\frac{t^2}{4r}-\frac{2t^2}{4r} = -\frac{t^2}{4r}[/tex]

Multiply:

[tex]\displaystyle 24r=-t^2, \, r\neq 0[/tex]

Solve for r:

[tex]\displaystyle r=-\frac{t^2}{24}[/tex]

Next, we are given that the width is 12 meters at ground level.

Hence, when h = 0, the difference of our roots is 12:

We have:

[tex]0=rx^2+tx[/tex]

Factor:

[tex]0=x(rx+t)[/tex]

By the Zero Product Property:

[tex]x=0\text{ or } rx+t=0[/tex]

Hence, the first zero is 0.

Therefore, the second zero must be 12 to ensure that our width is 12.

Let's isolate the second zero. Subtract t from both sides:

[tex]rx=-t[/tex]

Divide both sides by r:

[tex]\displaystyle x=-\frac{t}{r}[/tex]

We know that this zero must be 12. Thus:

[tex]\displaystyle 12=-\frac{t}{r}[/tex]

We have previously solved for r. Substitute:

[tex]\displaystyle 12=-\frac{t}{-\dfrac{t^2}{24}}[/tex]

Simplify:

[tex]\displaystyle 12=\frac{24}{t}[/tex]

Take the reciprocal of both sides:

[tex]\displaystyle \frac{t}{24}=\frac{1}{12}[/tex]

Multiply. Hence, the value of t is:

[tex]t=2[/tex]

Find r. Recall that:

[tex]\displaystyle r=-\frac{t^2}{24}[/tex]

Therefore:

[tex]\displaystyle r=-\frac{(2)^2}{24}=-\frac{4}{24}=-\frac{1}{6}[/tex]

Then in conclusion, our equation will be:

[tex]\displaystyle h=-\frac{1}{6}x^2+2x[/tex]

Answer:

1/2+1/4

4/8+2/8

6/8

3/4

Step-by-step explanation:

Answer:

The answer is 3/4.

Step-by-step explanation:

1/2+1/4

First we want to get a common denominator so that they can be added together.

1/2 * 2/2 = 2/4

We multiplied 1/2 by 2/2 so that both terms have a denominator of 4. Note that we also multiplied the top and bottom of 1/2 because we have to keep the value of the fraction the same.

Now we just add the fractions together.

2/4 + 1/4 = 3/4

So 3/4 is the answer. It is already in its simplest form meaning it cannot be simplified further.
